Description

FIELD OF THE INVENTION

[0001] The present invention relates to a method for development processing a photographic material having a magnetic recording layer and, more particularly, to a processing method in which a read error of a magnetic information from the magnetic recording layer of a photographic material after development processing is prevented.

BACKGROUND OF THE INVENTION

[0002] In a silver halide photographic material (hereinafter, referred to as a photographic material or a film), it has been almost impossible to input various informations of the time when photographing using a camera (e.g., the date of photographing, the weather, the enlargement ratio, the number of sheets of printing), except for only being capable of inputting the date of photographing optically. Further, inputting informations to a photographic material when printing has been completely impossible, which has been hindrance to speedup of the processing and reduction in cost.

[0003] It is a very important means to input various informations into a photographic material for improving and more simplifying the manipulation of a camera in future. As such a means of inputting informations, a magnetic recording method has been variously studied because it is capable of arbitrarily inputting and outputting informations and due to its inexpensiveness.

[0004] It has become feasible to input various informations to a photographic material by providing a magnetic recording layer in a photographic material which was formerly difficult, that is, the conditions when developing and printing have become possible to be inputted in a magnetic recording layer of a photographic material, e.g., the date of photographing, the weather, the conditions of lighting, the conditions at the time of photographing such as the reduction/enlargement ratio, etc., the number of sheets of reprinting, the place to be zoomed, and the messages. Further, a magnetic recording layer can be applied as a means of input and output signals when a photographic material is directly outputted to a television/video signals to form images, therefore, this is a very promising field.

[0005] However, it has been found that, with respect to input and output of informations, the input and output error due to the space loss, in particular, the output error which is generated by development processing is a severe problem when handling a photographic material provided with a magnetic recording layer.

[0006] Major causes of the space loss include the components coated on the side of a photographic material on which a magnetic recording layer is provided (e.g., magnetic grains and binder components), dusts adhered on the film during development processing, components of the processing solution, dirt from the hands adhered on the film, and dust in the atmosphere. A magnetic output error is generated presumably because they adhere and accumulate on the surface of a magnetic head while a film is traveling to cause the space loss between the film and the magnetic head.

[0007] As a method for solving the input and output error attributable to the space loss, the techniques of inclusion of a lubricating agent in a magnetic recording layer have been proposed in JP-A-4-73743 and JP-A-4-124659 (the term "JP-A" as used herein refers to a "published unexamined Japanese patent application"). It is also disclosed in JP-A-4-73736 and JP-A-6-161033 that this problem can be resolved by the addition of grains insoluble in a developing solution into a surface layer of the support on which the magnetic recording layer is provided such that the surface has projections having an average height of about from 0.1 to 3.0 µm. However, neither of these methods could provide a sufficient effect with respect to the output reduction of magnetic recording after development processing.

SUMMARY OF THE INVENTION

[0008] An object of the present invention is to provide a processing method of a photographic material having a magnetic recording layer in which the magnetic output is not reduced after processing.

[0009] Other objects and effects of the present invention will be apparent from the following description.

[0010] The present invention relates to, as a first embodiment, a method for development processing a silver halide color photographic material comprising a support having thereon a magnetic recording layer, wherein the conductivity of a final processing solution of the development processing is 0.1 mS/cm or less.

[0011] The present invention also relates to, as a second embodiment, a method for development processing a silver halide color photographic material comprising a support having thereon a magnetic recording layer, wherein the calcium concentration in a final processing solution of the development processing is 5 mg/ℓ or less.

[0012] The present invention further relates to, as a third embodiment, a method for development processing a silver halide color photographic material comprising a support having thereon a magnetic recording layer, wherein the adhered amount of a final processing solution remained on a surface of the photographic material on which the magnetic recording layer is provided after development processing is 0.3 ml/m² or less.

[0013] In the first embodiment of the present invention, it is preferred that a color developing solution used in the method for development processing does not contain hydroxylamine, and it is also preferred that the final processing solution contains 1,2-benzisothiazolin-3-one.

[0014] In the first embodiment of the present invention, it is further preferred that the adhered amount of the final processing solution remained on a surface of the photographic material on which the magnetic recording layer is provided after development processing is 0.3 ml/m² or less.

DETAILED DESCRIPTION OF THE INVENTION

[0015] The silver halide color photographic material having a magnetic recording layer of the present invention is subjected to ordinary color development processing (hereinafter referred to as only processing) then drying.

[0016] Magnetic recording is generally carried out before processing and reading is carried out after processing in many cases, and it has been found that adhered materials accumulate on the surface of the magnetic head during reading of the information after processing to cause the space loss between the film and the magnetic head, thereby an output is reduced. As a result of analyzing this phenomenon, the present inventors have found that the components of the processing solution adhered after processing on the side of the film on which the magnetic recording layer is provided, in particular, the ionic component causes the above reduction of the output.

[0017] The method of the present invention comprises conducting any one of reducing the conductivity of the final processing solution of the development processing to 0.1 mS/cm or less, reducing the calcium concentration in the final processing solution to 5 mg/ℓ or less, or reducing the adhered amount of the final processing solution to 0.3 ml/m² or less which is remained after development processing on the surface of the silver halide color photographic material on which the magnetic recording layer is provided.

[0018] Further, it has also been found that the curling characteristics after processing of the photographic material can be improved by the present invention.

[0019] In the present invention, the term "final processing solution" means a processing solution just before the drying process, that is, a stabilizing solution or a rinsing solution, with a stabilizing solution being particularly effective.

[0020] The present invention is conspicuously effective when a processing solution containing a surfactant is used as the final processing solution.

[0021] A method for reducing the conductivity of the final processing solution to 0.1 mS/cm or less (first embodiment) is described below.

[0022] A processing solution such as a stabilizing solution and a rinsing solution contains various compounds for stabilizing images or other purposes. For reducing the conductivity of the final processing solution, it is effective to reduce ionic compounds in the chemicals which are added as the components of the final processing solution, and also it is effective to previously remove ionic compounds from water to which these chemicals are to be dissolved (hereinafter referred to as preparation water). Further, it is also effective that washing and stabilizing steps are carried out by a multistage countercurrent system to reduce the amount of carryover of the previous processing solution by the photographic material.

[0023] As a method of removing ionic compounds from the preparation water, methods such as distillation, amphoteric ion exchange and reverse osmosis can be utilized. It is not preferred to apply these methods to a stabilizing solution or a replenisher thereof, since the performances of the stabilizing solution (e.g., stabilization of images, prevention of staining of a film, liquid extraction of a film) are deteriorated by the removal or reduction of the compounds added in the stabilizing solution.

[0024] Most preferred method of the above is a method of amphoteric ion exchanging the preparation water previously.

[0025] In the amphoteric ion exchange method, the preparation water is contacted with various ion exchangers such as an ion exchange resin and an ion exchange membrane with a method of using an ion exchange resin being most preferred. When using an ion exchange resin in the amphoteric ion exchange method, an H-type strongly acidic cation exchange resin and an OH-type strongly basic anion exchange resin are preferably used in admixture. It is preferred that the preparation water is passed through a column packed with the mixture of these resins. The passing rate is generally from 1 to 100 times, preferably from 5 to 50 times, of the volume of resins per hour. As the structure of a resin, a gel type, a porous type and a support carrying type can be used.

[0026] Specific examples of ion exchange resins include combinations of Amberlite IR-120B and IRA-400 manufactured by Rohm & Haas and Diaion SK-1B and SA-10A or SA-20A manufactured by Mitsubishi Kasei Corp. but the present invention is not limited thereto.

[0027] A reverse osmosis equipment for reverse osmosis treating the preparation water is preferably a low pressure type equipment, for example, about from 2 to 30 kg/cm². As a reverse osmosis membrane, a cellulose acetate membrane, an ethyl cellulose-polyacrylic acid membrane, a polyacrylonitrile membrane, and a polybutylene carbonate membrane can be used. Specific examples include NTR-959HR, NTR-950UP, NTR-729HF, NTR-7250, NTR-719HF, NTR-7410, and NTR-7450 manufactured by Nitto Kagaku Kogyo Co., Ltd., UTC-70, UTC-40HR, SC-3000, SU-700, SU-410, SU-600, SU-200S, and PEC-1000 manufactured by Toray Industries Inc., BW-30, HR-30, NF-40, NF-40HF, NF-50, and NF-70 manufactured by Film Tec (Dow) Co., and Permasep B-9, B-10, B-15 and C-1 manufactured by Du Pont, E.I. de Nemours.

[0028] The conductivity used herein is a value at 25°C and is measured by a commercially available conductivity meter. As a conductivity meter, for example, CM-40S and CM-60S manufactured by Toa Denpa Kogyo Co., Ltd. can be used.

[0029] The conductivity of the final processing solution is 0.1 mS/cm or less, preferably from 0.001 to 0.05 mS/cm, and more preferably from 0.003 to 0.03 mS/cm.

[0030] In the second embodiment of the present invention, the calcium concentration in the final processing solution is reduced to 5 mg/ℓ or less, preferably 3 mg/ℓ or less. The calcium concentration may be zero.

[0031] The calcium concentration means the total calcium concentration of the calcium compounds contained in one liter of the final processing solution and represented as the weight of calcium.

[0032] When reducing the calcium concentration in the final processing solution, as in the case of reducing the conductivity described above, it is also effective to reduce the calcium concentration in the processing chemicals and/or the preparation water thereof.

[0033] If the concentration of a calcium ion can be reduced, any of the above methods for reducing the conductivity can be used.

[0034] Other than the above methods, a cation exchange method can be used in which a calcium ion is exchanged with a monovalent ion such as sodium or potassium.

[0035] Examples of ion exchangers in the cation exchange method include an ion exchange resin, an ton exchange membrane and zeolite, with an ion exchange resin being most preferred of these.

[0036] A method of exchanging a calcium ion with an Na ion using a strongly acidic or a weakly acidic cation exchange resin as the ion exchange resin is preferred.

[0037] A method of using the cation exchange resin may be the same as the case of the above described amphoteric ion exchange method.

[0038] A method for reducing the adhered amount of the final processing solution to 0.3 ml/m² or less which is remained after development processing on the surface of the silver halide color photographic material on which the magnetic recording layer is provided (third embodiment) is described below.

[0039] The adhered amount of the remaining final processing solution used herein is the amount of the components of the final processing solution adhered on the film and remained after drying, and the remaining amount of the components of the final processing solution is expressed as the volume of the solution before drying.

[0040] The adhered amount of the remaining final processing solution can be measured by coating the surface of the film other than the surface having the magnetic recording layer after processing, extracting the components adhered on a definite area of the surface having the magnetic recording layer into distilled water at 25°C, and determining the concentration of the components in the water.

[0041] In general, the compound to be determined is the main component in the final processing solution but if such a compound cannot be determined, other compounds contained in the final processing solution may be determined. However, a compound that has a behavior of specific adsorption or an unstable compound cannot be used for the determination. In such a case, for the measurement of the adhered amount of the final processing solution, a definite amount of a compound (e.g., heavy metal ion or a fluorescent compound) is previously added in the final processing solution as a marker, and the determination can be conducted by measuring the marker in the solution extracted from the film after processing.

[0042] Various known methods can be used for reducing the adhered amount of the remaining final processing solution. Specifically, a method of squeezing the solution with a rubber blade or air, a method of wiping off the solution adhered with a water absorptive cloth or polymer, and a method of vibrating the film in the air before drying can be used.

[0043] When processing is carried out using a hanging type automatic processor, if a processing solution is pooled at a hanger or a clip part supporting a film, the amount of the solution adhered that part increases, which causes staining of the film or the reduction of output when reading magnetic information. Therefore, the structure which does not pool a processing solution is preferred. Specifically, the contact area of a hanger with a film is preferably as small as possible and not to provide a closed space between the hanger and the film.

[0044] Further, when a film is turned up and processed, if the film is dried with keeping in contact each other in the vicinity of the lower ends, the amount of the solution adhered that part also increases. Accordingly, the structure in which the clips attached to the lower ends of the film keep a distance between the films is preferred.

[0045] The adhered amount of the final processing solution which is remained after development processing on the surface of the silver halide color photographic material on which the magnetic recording layer is provided is preferably from 0 to 0.2 ml/m², particularly preferably from 0 to 0.1 ml/m².

[0046] When the final processing solution has the effect of stabilizing images, the solution is called a stabilizing solution and solutions other than that are called a rinsing solution.

[0047] The stabilizing solution and the rinsing solution are explained below.

[0048] The stabilizing solution contains image stabilizers, for example, formaldehyde, benzaldehydes such as m-hydroxybenzaldehyde, bisulfite addition products of formaldehyde, hexamethylenetetramine and derivatives thereof, hexahydrotriazine and derivatives thereof, dimethylolurea, N-methylol compounds such as N-methylolpyrazole, organic acids and pH buffers. The preferred amount added of these compounds is from 0.001 to 0.02 mol per liter of the stabilizing solution, and the lower the concentration of the free formaldehyde in the stabilizing solution, the less is the splashing of the formaldehyde gas, which is preferred. From these points, m-hydroxybenzaldehyde, hexamethylenetetramine, N-methylolazoles such as N-methylolpyrazole disclosed in JP-A-4-270344, and azolylmethylamines such as N,N'-bis(1,2,4-triazol-1-ylmethyl)piperazine, etc., disclosed in JP-A-4-313753 are preferred as dye image stabilizers. In particular, a combined use of azoles such as 1,2,4-triazole disclosed in JP-A-4-359249 (corresponding to EP-A-519190) with azolylmethylamine such as 1,4-bis(1,2,4-triazol-1-ylmethyl)-piperazine, and derivatives thereof is preferred because the high image stability can be obtained thereby and also which generates low vapor pressure of the formaldehyde. Further, it is preferred to include various compounds in the stabilizing solution, if necessary, for example, ammonium compounds such as ammonium chloride and ammonium sulfite, metal compounds such as Bi and Al, a whitening agent, a hardening agent, alkanolamine disclosed in U.S. Patent 4,786,583, and preservatives which can be generally included in fixing solutions and bleach-fixing solutions, e.g., sulfinic acid compounds as disclosed in JP-A-1-231051. These compounds each is generally added in an amount of from 0.01 to 1 g/ℓ, preferably from 0.05 to 0.5 g/ℓ.

[0049] The rinsing solution and the stabilizing solution can contain various surfactants to prevent the generation of water marks during drying of the processed photographic materials. Nonionic surfactants are preferably used, and ethylene oxide addition product of alkylphenol is particularly preferred. Octyl-, nonyl-, dodecyl-, and dinonylphenol are preferred as the alkylphenol and the addition mol number of the ethylene oxide is preferably from 8 to 14. Further, it is preferred to use silicone surfactants which have the high defoaming ability. The surfactant is generally added in an amount of from 0.001 to 5 g/ℓ, preferably from 0.05 to 0.5 g/ℓ.

[0050] The rinsing solution and the stabilizing solution are preferred to contain various kinds of chelating agents. Preferred examples of the chelating agents include aminopolycarboxylic acid, e.g., ethylenediaminetetraacetic acid and diethylenetriaminepentaacetic acid, organic phosphonic acid, e.g., 1-hydroxyethylidene-1,1-diphosphonic acid, N,N,N'-trimethylenephosphonic acid, diethylenetriamine-N,N,N',N'-tetramethylenephosphonic acid, and a hydrolysis product of a maleic anhydride polymer disclosed in EP-A-345172, and the like. The chelating agent is generally added in an amount of from 0.001 to 5 g/ℓ, preferably from 0.01 to 0.5 g/ℓ.

[0051] The rinsing solution and the stabilizing solution are preferred to contain 1,2-benzisothiazolin-3-one from not only stabilization of the processing solution but also capable of obtaining the effect of preventing the reduction of the magnetic output after processing. The amount added of this compound is from 0.01 to 0.5 mg, preferably from 0.03 to 0.3 mg, per liter of the processing solution.

[0052] The overflow generated by the replenishment of the above described rinsing solution and/or stabilizing solution can be reused in other steps such as a desilvering step, etc.

[0053] A processing method preferably used in the present invention is explained below.

[0054] The processing method may generally be effected by conducting a developing process, a desilvering process, and a finishing process, in this order.

[0055] The developing process may comprise color developing, or in a reversal process, black-and-white developing followed by color developing, and optionally a stopping process. The black-and-white developing may comprise a reversing process (such as reversal exposure and a reversal bath), a washing process, and a rinsing process.

[0056] The desilvering process may comprise a process, in which a material is processed with a solution having bleaching ability such as a bleaching solution and a bleach-fixing solution, and a process, in which a material is processed with a solution having a fixing ability, such as a fixing solution and a bleach-fixing solution. In the present invention, both the processes are conducted or only a bleach-fixing process is conducted.

[0057] After the desilvering process, a finishing process such as washing, rinsing or stabilizing is conducted. Any combination of them may be employed, and in general, washing or rinsing is conducted and stabilizing is then conducted.

[0058] The material thus processed by the above processes is then dried by a drying process.

[0059] The present invention can be applied to various silver halide color photographic materials such as color papers coated with a silver chlorobromide emulsion and a silver bromide emulsion, color autopositive paper, color negative films coated with a silver iodobromide emulsion, color reversal films and color reversal papers, and in particular, color negative films are preferred.

The above described binders can be used at this time, the same binders as the binder of the magnetic recording layer are preferably used. Photographic materials having a magnetic recording layer are disclosed, e.g. , in U.S. Patents 5,336,589, 5,250,404, 5,229,259, 5,215,874 and European Patent 466130.

The average molecular weight of the polyester used in the present invention is generally about 5,000 to 200,000. Tg of the polyester is generally 50°C or more, and preferably 90°C or more.

[0070] The polyester support may be heat treated at 40°C or more and less than Tg, more preferably at a temperature lower than Tg by 20°C or more and less than Tg, for the purpose of being reluctant to get curling habit. The heat treatment may be carried out at constant temperature within this range or may be carried out with cooling. The heat treatment time is from 0.1 hours to 1,500 hours, preferably from 0.5 hours to 200 hours. The heat treatment of the support may be carried out in a rolled state or may be carried out in a web state while transporting.

[0071] The surface of the support may be provided with unevenness (e.g., coating conductive inorganic fine grains such as SnO₂ or Sb₂O₅) to improve the surface state. Further, it is desired to contrive so as to prevent transfer of a cut end shape of the rolled support at the core part by providing knurling at the side edge part and making only the side edge part a little high. The heat treatment may be carried out at any stage of after formation of the support, after the surface treatment, after coating of a backing layer (an antistatic agent, a lubricating agent, etc.), or after undercoating, but preferably conducted after coating of an antistatic agent.

[0072] An ultraviolet absorbing agent may be incorporated into the polyester support. Further, light piping can be prevented by incorporating the commercially available dye or pigment for polyester such as Diaresin manufactured by Mitsubishi Kasei Corp. or Kayaset manufactured by Nippon Kayaku Co., Ltd. into the support.

SiO₂, TiO₂, inorganic fine grains or polymethyl methacrylate copolymer fine grains (0.01 to 10 µm) may be contained as a matting agent.

[0075] Further, antistatic agents are preferably used in the photographic material of the present invention. Examples of such antistatic agents include polymers containing carboxylic acid, carboxylate and sulfonate, cationic polymers, and ionic surfactant compounds.

[0076] The most preferred antistatic agents are fine grains of a crystalline metal oxide of at least one selected from ZnO, TiO₂, SnO₂, Al₂O₃, In₂O₃, SiO₂, MgO, BaO, MoO₃ and V₂O₅ having a volume resistivity of 10⁷Ω·cm or less, more preferably 10⁵Ω·cm or less and having a grain size of from 0.001 to 1.0 µm or fine grains of composite oxides of them (Sb, P, B, In, S, Si, C), and fine grains of a metal oxide in the form of sol or fine grains of composite oxides of them. The addition amount to the photographic material is preferably from 5 to 500 mg/m² and particularly preferably from 10 to 350 mg/m². The ratio of the crystalline oxides or composite oxides thereof to the binder is preferably from 1/300 to 100/1, and more preferably from 1/100 to 100/5.

[0077] It is preferred for the photographic material of the present invention to have a lubricating property. The lubricating agent-containing layer is preferably provided on both of a light-sensitive layer side and a backing layer side. Preferred lubricating property is a dynamic friction coefficient of from 0.01 to 0.25. Measurement of the lubricating property is conducted using a stainless steel ball having a diameter of 5 mm at a transporting speed of 60 cm/min (25°C, 60% RH). In this evaluation, when the opposite material is replaced with the light-sensitive layer surface, almost the same level of value can be obtained.

[0078] Examples of the lubricating agent which can be used in the present invention include polyorganosiloxane, higher fatty acid amide, higher fatty acid metal salt, esters of higher fatty acid and higher alcohol.

[0079] Further, the photographic material of the present invention preferably contains a matting agent. The matting agent may be added to either of an emulsion layer side or a backing layer side but it is particularly preferably to be added to the outermost layer of emulsion layers. The matting agent may be either soluble or insoluble in the processing solution, preferably both types are used in combination. For example, polymethyl methacrylate, copolymer of methyl methacrylate and methacrylic acid (methyl methacrylate/methacrylic acid = 9/1 or 5/5 by mol), and polystyrene grains are preferably used. The average grain size is preferably from 0.8 to 10 µm, and grain size distribution is preferably narrow, preferably 90% or more of the entire grain number accounts for from 0.9 to 1.1 times of the average grain size.

Usually, a plastic patrone is produced using plastics including carbon black or a pigment to impart light shielding. The size of the patrone may be 135 size of the present as it is, or for a compact size camera, it is effective that the diameter of the patrone of 25 mm of the present 135 size may be decreased to 22 mm or less. The capacity of the case of the patrone is 30 cm³ or less and preferably 25 cm³ or less. The weight of the plastics used for the patrone and patrone case is preferably from 5 g to 15 g.

Preparation of Dispersion of Organic Solid Dispersion Dye

[0137] ExF-2 shown below was dispersed according to the following method. 21.7 ml of water, 3 ml of a 5% aqueous solution of sodium p-octylphenoxyethoxyethoxyethanesulfonate, and 0.5 g of a 5% aqueous solution of p-octylphenoxypolyoxyethylene ether (polymerization degree: 10) were put in a pot mill having a capacity of 700 ml, and 5.0 g of Dye ExF-2 and 500 ml of zirconium oxide beads (diameter: 1 mm) were added thereto and the content was dispersed for 2 hours. The vibrating ball mill which was used was BO type ball mill manufactured by Chuo Koki. The content was taken out after dispersion and added to 8 g of a 12.5% aqueous solution of gelatin and the beads were removed by filtration and the gelatin dispersion of the dye was obtained. The average grain size of fine grains of the dye was 0.44 µm.

[0138] Solid dispersions of ExF-3, ExF-4 and ExF-6 were obtained in the same manner. The average grain sizes of fine grains of the dyes were 0.24 µm, 0.45 µm and 0.52 µm, respectively. ExF-5 was dispersed according to the microprecipitation dispersion method disclosed in Working Example 1 of EP-A-549489. The average grain size was 0.06 µm.

[0139] The thus prepared photographic material was cut to a size of 24 mm in width and 160 cm in length, and two perforations of 2 mm square at an interval of 5.8 mm were provided 0.7 mm inside from one side of the width direction in the length direction of the photographic material. The sample provided with this set of two perforations at intervals of 32 mm was prepared and encased in the plastic film cartridge explained in FIG. 1 to FIG. 7 in U.S. Patent 5,296,887.

[0140] This sample was charged in a camera and photographed standard subjects with the optimal exposure. Subsequently, digital saturation recording of recording wavelength of 50 µm was conducted from the side of the support having the magnetic recording layer using an audio type magnetic recording head made of Permalloy with head gap of 5 µm, the number of turns of 50 at a feed rate of 100 mm/sec.

[0141] One hundred and two sheets of the samples thus written with magnetic informations were continuously processed using the following described automatic processor with each stabilizing or rinsing solution.

[0142] Processing was carried out using a pendant type automatic processor H4-220S type manufactured by Noritsu Koki Co., Ltd. The center part of the film was hung on a hanger with the emulsion surface outside and clips were attached at both ends of the film. The hanger supported the near sides of the film edges so as not to touch the image part, and so that the processing solution did not stay at this part. A plastic pole was fixed between clips of both ends to make an interval of 10 cm to prevent the film from touching each other.

[0151] Water only

[0152] With respect to each processing solution in stabilizing process, Sample Nos. 4, 6 and 8 were processed with tap water, Sample Nos. 1, 5 and 7 with the following described amphoteric ion exchange water, Nos. 2 and 3 with the mixed water of amphoteric ion exchange water and tap water, and No. 9 with the cation exchange water shown below.

Amphoteric Ion Exchange Water

[0153] Tap water was passed through a mixed bed column packed with an H-type strongly acidic cation exchange resin (Amberlite IR-120B of Rohm & Haas) and an OH-type strongly basic anion exchange resin (Amberlite IR-400 of Rohm & Haas) and treated so as to reduce the calcium concentration to 3 mg/ℓ.

Cation Ion Exchange Water

[0154] Tap water was passed through a mixed bed column packed with an Na-type strongly acidic cation exchange resin (Amberlite IR-120B of Rohm & Haas) and treated so as to reduce the calcium concentration to 1 mg/ℓ.

[0155] The above photographic materials after processing were measured for the output signal level of the isolated reproduction wave using a magnetic reproducing head made of Sendust with head gap of 2.5 µm, the number of turns of 2,000.

[0156] The same magnetic reproducing heads were arranged in series with the intervals of 5 cm and measurement was conducted using the rear head.

[0157] From the above results, the average output level of the first photographic material was taken as 100, and the average output of the 100th based on the first output was represented by percentage and shown in Table 1 (magnetic output).

[0158] Further, 101st photographic material after processing was allowed to stand for 5 hours in a room of 20°C, 50% RH with the emulsion surface down, then the length in the width direction at the center of the film was measured using calipers. In the case of the film curls, the length is less than 24 mm (curling characteristics).

Criteria of evaluation:

[0159] 

AA:

24.0 mm (no curling)

A:

23.8 mm or more

B:

23.5 mm or more and less than 23.8 mm

C:

less than 23.5 mm

[0160] The results are also shown in Table 1.

[0161] The adhered amount of each of the final processing solution of the backing layer side of the 102nd photographic material was measured, all were 1.0 ml/m² or more.

[0162] The measured value was obtained by extracting 1,2-benzisothiazolin-3-one adhered on the backing layer side with distilled water and determined through a liquid chromatography.

[0163] The conductivity of each final processing solution was the value at 25°C measured with a conductivity meter CM-60S manufactured by Toa Denpa Kogyo Co., Ltd. Further, the concentration of calcium in the final processing solution was measured according to the atomic absorption method.

[0164] As is shown in Table 2, in the processing using comparative final processing solutions, as Nos. 4, 6 and 8, when reading of the magnetic recording informations of 100 sheets were conducted continuously, the output of the 100th film was largely reduced.

[0165] On the contrary, in the processing using processing solutions of the present invention, 70% or more of the magnetic recording informations have been secured, and the lower the conductivity or the lower the calcium concentration, the better was the results obtained. Further, with respect to curling characteristics, excellent results were obtained when using the final processing solutions of the present invention.

[0166] After 102 sheets of the above films were processed in each processing, color negative films 160S manufactured by Fuji Photo Film Co., Ltd. which were exposed with white light so as to obtain magenta density of 1.5 were processed. The films after processing were preserved under 60°C, 60% RH conditions for three days, then magenta density was measured. Nos. 5 to 8 were all discolored to 1.3 or less but densities of Nos. 1 to 4 and No. 9 were all 1.45 or more and image stabilizing effect was sufficient.

EXAMPLE 2

[0167] In processing of No. 4 of Example 1, after coming out from the final processing solution and before entering drying section, films were subjected to treatment of reducing the adhered amount of solution on the back surface by blowing dry air (Nos. 11 to 13). In processing of No. 3 of Example 1, the same procedures as in Nos. 11 to 13 were conducted (Nos. 14 to 16). Control of the adhered amount of solution was conducted by changing the blowing time of dry air.

[0168] Evaluation was carried out in the same manner as in Example 1. As shown in Table 3, magnetic output and curling characteristics were improved by reducing the adhered amount of the final processing solution. Particularly, extremely superior results were obtained if the conductivity of the final processing solution was 0.1 mS/cm or less.

EXAMPLE 3

[0169] The following processing was carried out with samples' prepared in Example 1.

[0170] Each processing was conducted using an automatic processor FP-560B manufactured by Fuji Photo Film Co., Ltd. according to the following. The processor was modified such that all of the overflow from the bleaching bath was introduced to the waste solution tank not to the next bath. FP-560B is loaded with the evaporation compensation means disclosed in Kokai Giho No. 94-4992, Hatsumei Kyokai.

[0171] The processing step and the composition of each processing solution are shown below.

[0173] Stabilization and fixation were conducted in a countercurrent system from (2) to (1), and the overflow from the washing tank was all introduced into the fixing tank (2). Further, the amount of carryover of the developing solution into the bleaching step, the amount of carryover of the bleaching solution to the fixing step, and the amount of carryover of the fixing solution to the washing step were 2.5 ml, 2.0 ml and 2.0 ml per 1.1 meter of 35 mm wide photographic material, respectively. Further, the crossover time was 6 seconds in each case, and this time is included in the processing time of the previous step.

[0174] Open areas of the above processor were 100 cm² with the color developing solution, 120 cm² with the bleaching solution and 100 cm² with other processing solutions.

The pH of this washing water was in the range of from 6.5 to 7.5.

Stabilizing Solution

[0181] The same as No. 2 in Example 1.

[0182] Each developing solution was aged in a processor for one week while controlling the temperature, then processing was carried out.

[0183] The processing in which the preservatives shown in Table 4 were used was evaluated for magnetic output in the same manner as in Example 1.

[0184] As is understood from Table 4, if hydroxylamine is used in a color developing solution, magnetic output is deteriorated.

[0185] Further, processing was carried out in the same manner as No. 21 except for removing 1,2-benzisothiazolin-3-one from the stabilizing solution in No. 21. in Table 4 (No. 25) and evaluation of magnetic output was conducted. As a result, the magnetic output of No. 25 was 85%, from which it was found that the reduction of the output of No. 25 was large compared with No. 21.

[0186] While the invention has been described in detail and with reference to specific examples thereof, it will be apparent to one skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope thereof.
