Field of the Invention
[0001] The present invention relates to a method for processing a silver halide photographic
light-sensitive material, particularly relates to a method for processing a silver
halide photographic light-sensitive material which is effective to reduce the amount
of waste liquid of photographic processing effluent.
Background of the Invention
[0002] Recently, makers of photographic material have made efforts for reducing the amount
of waste liquid formed in a photographic processing to a limit relating to a tendency
of environment protection.
[0003] On the other hand, C-41RA Processing of Eastman Kodak Co., Ltd., which is a processing
most widely used in-shop laboratories or mini-labo's, is composed of 4 steps, and
the replenishing amounts per roll of 135 size, 24 exp. film are 23 ml for color developing
step, 5 ml for bleaching step, 33 ml for fixing step and 40 ml for stabilizing step,
respectively. The replenishing amount for the stabilizing solution is largest in these
steps. Therefore, reducing in the replenishing amount of the stabilizing solution
has been demanded.
[0004] However, when the replenishing amount of the stabilizing solution is simply reduced,
a fixing agent such as thiosulfate, a component of a fixing solution, is accumulated
in the stabilizing solution. The fixing agent is carried into the stabilizing solution
from the previous fixing bath by a light-sensitive material processed on which the
fixing agent is adhered. The accumulated fixing agent causes formation of a stain
on the back surface of the light-sensitive material. The satin appears on a printed
picture from the light-sensitive material and causes a serious defect destroying the
commercial value of the print. Further, the renewing ratio of the stabilizing solution
is lowered by the reduction of the replenishing amount, which causes an extension
of time for oxidation of the stabilizing solution by air. As a result of that, a problem
of formation of defects caused by sulfurization is apt to raise. Further, formaldehyde
is usually contained in the stabilizing solution for preventing stain formation in
a unexposed area of the processed light sensitive material during storage and discoloration
of color image by blocking the reactive site of a unreacted magenta coupler remained
in the light-sensitive material. The formaldehyde reacts and forms an adduct with
sulfite, which is carried over from the fixing solution accompanied with the thiosulfate
to the stabilizing solution. As a result of that, the effect of formaldehyde improving
the stability of dye is lost and a serious problem of acceleration of sulfurizaton
in the stabilizing solution is raised.
[0005] Recently, solidifying a processing composition for a silver halide light-sensitive
material is tried from the view point of reducing environment pollution and improving
working load for preparating a processing solution. For instance, Japanese Patent
Publication Open to Public Inspection (JP O.P.I.) Nos. 5-119454/1993, 5-165174/1993
and 5-232656/1993 each describe a technology in which a solid processing composition
containing thiosulfate is directly supplied into a solution having a fixing ability.
[0006] It would be unquestionable that reducing the use of plastic bottles for bottling
a replenisher solution kit and lowering working load at the time of preparation of
a replenisher solution can be attained by applying the technology disclosed in the
above publications. However, it has been found that the problems mentioned below cannot
be solved by the above technology only.
[0007] In the above-mentioned patent publications, a fixing time of 90 seconds for color
negative film is disclosed as an embodiment of the technology. Generally, it is necessary
to increase the concentration of thiosulfate in a processing solution to a certain
level for attaining such rapidness of the processing. In the case in which thiosulfate
concentration is made higher, it is apt to occur a problem, when daily cleaning of
transferring rollers arranged between the first and the second fixing tank or a fixing
tank and next tank such as a stabilizing tank or a washing tank is failed, that a
hydrophobic decomposition substance of thiosulfate is formed by drying and air-oxidizing
of drops of the processing solution adhered on the rollers by a light-sensitive material
processed. The hydrophobic substance is tightly fixed on the surface of the rollers
by hydrophilic bonding. The hydrophobic substance tightly adhered on the surfaces
of the rollers may causes an irrevocable defect such as scratches on the light-sensitive
material.
[0008] Further, it has been found, in the relation between concentration of thiosulfate
and fixing property, that although the fixing property is raised with increasing the
thiosulfate concentration until a certain value, the fixing property is lowered in
reverse when the concentration exceeds the certain value. The thiosulfate concentration
for enabling the above-mentioned rapid processing corresponds to the above critical
concentration. Accordingly, when the amount of light-sensitive material to be processed
per day is small, the thiosulfate concentration in the processing solution is apt
to raised by evaporation of the solution. The raising in the thiosulfate concentration
causes a problem that the fixing property of the solution is degraded. Further, crystals
of thiosulfate are precipitated and grown in the processing solution when such the
concentrated processing solution as described above is stood under a low temperature
condition such as in a closing term in winter. The precipitation of thiosulfate causes
blocking of circulation of the processing solution and degrades the property of the
processing solution due to lowering the effective amount of thiosulfate in the processing
solution.
[0009] On the other hand, in a case that a solid processing composition is stored for a
prolonged period on the deck of a ship when the composition is transported by a ship,
a yellow water-insoluble sulfurous substance is formed in a thiosulfate-containing
solid composition for fixer or bleach-fixer during the storage under a such high temperature
condition. The insoluble sulfurous substance adheres to a filter stalled in the fixing
tank or bleach-fixing tank of processor and causes blocking of the filter. As a result
of that, photographic properties of the processing solution are degraded due to in
sufficient circulation of the processing solution. Further, it has been found that
the precipitated sulfurous substance adheres on the surface of the processed light-sensitive
material and considerably spoils the commercial value of the processed light-sensitive
material.
[0010] In case of the solid composition is in a form of granule or tablet, the formation
of sulfurous substance by decomposition of thiosulfate causes lowering the combining
force between components of the composition around the sulfrous substance in the granule
or the tablet. As a result of this, the solid composition is easily powdered by vibration
or friction.
[0011] A solution for processing a silver halide photographic light-sensitive material having
a fixing ability such as a fixier or a bleach-fixer contains compound which is capable
of forming a water-soluble complex salt by reaction with silver halide for example,
a thiosulfate such as potassium thiosulfate, sodium thiosulfate or ammonium thiosulfate,
a thiocyanate such as potassium thiocyanate, sodium thiocyanate or ammonium thiocyanate,
thiourea or a thioether is usually contained as a fixing agent. Among them, thiosulfate
particularly ammonium thiosulfate has been frequently used by reason of that the compound
is superior in the processing property, stability and solubility thereof.
[0012] However, a strong odor of evaporated ammonia is generated when ammonium ions are
contained in a processing solution. It has been tried, therefore, to reduce the using
amount of ammonium salt for improvement of working environment.
[0013] However, the solubility of potassium thiosulfate or sodium thiosulfate is lower than
that of ammonium thiosulfate. Accordingly, the fixing agent is easily precipitated
in a concentrated solution at low temperature when these thiosulfates are used instead
of ammonium salt. The concentration of the solution is particularly occurred in a
mini-labo when the amount of light-sensitive material to be processed is small. Further,
in a system with a small amount of replenishing, it is required to increase the concentration
of thiosulfate to compensate degradation in processing ability and stability of the
processing solution. It has been found that the increasing in the thiosulfate concentration
causes adhering sulfur on transferring rollers exposed to air, particularly on rollers
for transferring provided at a position between a processing tank and the next processing
tank (inter-tank rollers).

Detailed Description of the Invention
[0019] The inventors found out that the concentration of thiosulfate salt necessary for
completing a fixing reaction can be reduced by adding at least one compound represented
by Formula I, II, III, IV or V (hereinafter also referred as compound of the invention")
into a fixing solution, and that the replenishing amount of a stabilizing solution
can be reduced without formation of a stain on the back surface of a light-sensitive
material processed and sulfurization or formation of a water-insoluble sulfurous substance
in the stabilizing solution by substantially omitting formaldehyde which is reactive
with sulfite carried over from the fixing solution.
[0020] The amount of thiosulfate necessary to complete a fixing reaction can be reduced
by addition of a compound represented by Formula I, II, III, IV or V to a solid processing
composition containing thiosulfate. By the reduction in the amount of thiosulfate,
adhesion of the decomposition substance of thiosulfate on the surface of the inter-tank
transferring rollers can be prevented and the fixing ability of the processing solution
can be stably maintained when the amount of the light-sensitive material to be processed
per day is small and the solution is concentrated.
[0021] The processing solution can maintain a stable fixing ability by the use of the above
compound even when the concentration of thiosulfate in the processing solution is
varied.
[0022] The inventors further found out that the concentration of thiosulfate salt necessary
for completing a fixing reaction can be decreased by adding at least one compound
represented by Formulas I to V into a fixing solution, and that the processing ability
of a fixing solution can be maintained without raising the thiosulfate ion concentration
by optimizing the ratio of the amount of ammonium thiosulfate to the amount of potassium
thiosulfate and/or sodium thiosulfate. Thus the present invention has been accomplished.
[0023] A processing method has been known in which a mercapto heterocyclic compound is added
to a processing solution. The method includes, for example, a method in which the
compound is added to a fixing solution such as described in Japanese Patent Publication
Open for Public Inspection (JP O. P. I.) No. 1-261640/1989, a method in which the
compound is added to a solution of prebath for a bleaching solution such as described
in JP O. P. I. No. 54-52534/1979, and a method in which the compound is added to a
bleach-fixing solution such as described in British Patent No. 1,138,842. However,
these publication does not describe with respect to any stabilizing solution containing
no formaldehyde to be used in the following step, and the technical concept of the
invention is not expected from the description therein.
[0024] The compound represented by Formula I to IV or V is known as a bleach accelerating
agent to be used in a bleaching process in which metallic silver is oxidized (refer
JP O.P.I. 61-250646/1986). However, it is surprising fact that the compound has a
fixing accelerating effect. The compound accelerates a fixing process which is applied
after the bleaching step, and silver ions are dissolved and removed from the light-sensitive
material in this process. The effect is a novel fact which is found by the inventors
as a result of try-and-error experiments carried out by the inventors.
[0025] The solubility of the solid processing composition can be stably maintained and the
precipitation of sulfurous substance formed from thiosulfate can be prevented by the
use of a compound represented by Formula I to IV or V even when the composition is
stored under a high temperature condition of 40 to 50°C for a prolonged period.
[0026] When the solid processing composition is in a form of granule or tablet, the powdering
of the composition after storage under a high temperature condition can be prevented
by adding at least one compound represented by Formula I to IV or V in the solid processing
composition.

[0127] Among the above-given exemplified compounds, C-(21) through (64) are preferable and
C-(21) through (48) are more preferable.
[0128] These saccharides may be added in an amount within the range of, preferably, 0.5%
(W/W) to 30% (W/W) and, more preferably, 1.0% (W/W) to 20% (W/W) of an unit weight
of the solid processing composition.
[0129] Saccharides are made widely present in nature and are readily available on the market.
A variety of derivatives can also readily be synthesized by carrying out a reduction,
oxidation, dehydration reaction or the like.
[0130] The above mentioned compounds represented by Formula (I), polyvinylpyrrolidones,
polyvinyl alcohols and suggars can enhance the effects of the solid processing compositio
when they are contained in the composition either in a form of the law material of
powder, in a granulated form or in a form granulated together with thiosulfates.
[0131] The prevention of formation of the sulfurous substance and of formation of powder
after storage under a high temperature condition in the solid processing composition
can be further enhanced by addition of a sulfite or a pyrosulfite. The sulfite and
pyrosulfite include ammonium salt, sodium salt and potassium salt thereof, and sodium
salt and potassium salt are preferable from the view point of the above-mentioned
effects. The shape of the solid composition includes a shape of powder, granule and
tablet. Among them the preferable shape is a granule and a table, particularly a tablet.
[0132] Here, "powder" means a mass of fine crystals. "Granule" means grains having a diameter
of 50 to 5,000 µm, which is preferably prepared by granulating a powder. "Tablet"
means one which is prepared by shaping a powder or granules in a required tablet form
by compression. As the shaping method of the tablet, it is preferable to tablet by
compression after granulating the powder or granules, because a stable processing
ability can be maintained by thus prepared tablet.
[0133] As the granulating methods for preparation of tablet, a known method such as a tumbling
granulation method, extrusion granulation method, compression granulation method,
crushing granulation method, agitation granulation method, fluid-bed granulation method
and spray granulation method can be used. The average size of the granulated particles
is preferably 100 to 2,000 µm, more preferably 200 to 1,500 µm, from the viewpoint
that a ununiformity or demixing of the composition is hardly formed at the time of
mixing and compression of the granulated particles for tableting. The granulated particles
preferably has a particle size distribution in which the 50% of the particles each
have a particle size falling within the range of ±250 µm. Thus obtained granulated
particles are used as granulated composition without any treatment. For compressing
the granulated particles, known compressing machines, such as an oil hydraulic pressing
machine, single tableting machine, rotary tableting machine and briquetting machine,
can be used. The tablet may be prepared by tabulating a mixture of the granulated
particles prepared by the above granulating method and crystals of a raw material
available on the market.
[0134] Although the solid processing composition prepared by compression can be take an
optional shape, a cylindrical shape or tablet shape is preferable from the viewpoint
of producibility, handling property and dust formation on the user's side.
[0135] The replenishing composition for the fixer is preferably one conntaining a small
amount of ammonium thiosulfate for improving the working environment. It is preferable
that the ratio of ammonium thiosulfate in the total amount of thiosulfates in the
fixing solution is not more than 70 mole %, more preferably not more than 30 mole
%. The ratio of the sum of the weight of compounds represented by Formula I to IV
or V to the weight of thiosulfate contained in the composition is preferabaly within
the range of from 0.05% to 5% by weight, more preferably within the range of from
0.2% to 2% by weight.
[0136] The interval from the time at which the fixing process of a light-sensitive material
is completed, to the time at which the light-sensitive material is touched with the
stabilizing solution, is preferably not more than 7 seconds, more preferably not more
than 5 seconds, further preferably 1 to 3 seconds.
[0137] The number of the stabilizing tank may be one, but the number of the tank may be
increased to 2 to 10. Although the replenishing amount of the stabilizing solution
can be reduced by increasing the number of stabilizing tank, the number of stabilizing
tank is preferably 2 to 6 from the viewpoint of the miniaturization of automatic processor.
The replenisher may be separately supplied at several portions, but it is preferable
that the replenishing is carried out by a counter-current method (multi-steps counter-current
method) in which the replenisher is supplied to a tank provided at a downstream portion
with respect to the flow of the light-sensitive material and the overflow solution
from the tank (including a solution flowing through a pipe when the tanks are connected
by a pipe provided under the surface of the solution) is pour into a tank provided
at upperstream of the tank. The counter-current method includes a cascade method.
It is further preferable that the replenisher is supplied to the last stabilizing
tank among two or more stabilizing tanks and the over flow solution is poured into
previous tank in sequence.
[0138] The replenishing amount of the stabilizing solution can be considerably reduced by
approximately 900 ml or less per square meter of the light-sensitive material processed
only by making use of the compound of the invention represented by Formula (1). However,
it is made possible to obtain the effects of the invention by using the above-mentioned
treatment within the range of the replenishing amount of 50 to 800 ml per square meter
of the light-sensitive material. For sufficiently enhancing the effects of the invention,
the replenishing amount of the stabilizing solution is preferably 100 to 650 ml, more
preferably 150 to 500 ml pre square meter of the light-sensitive material.
[0139] The replenishing amount can be further reduced by introducing a processing solution
pumped out from the stabilizing tank to the fixing solution in the fixing treatment
process.
[0140] In the processing method relating the invention, the processes of (1) Color developing
→ Bleaching → Fixing → Stabilizing, (2) Color developing → Bleaching → Fixing → 1
st Stabilizing → 2
nd Stabilizing, and (3) Color developing → Bleaching → Bleach-fixing → 1
st Stabilizing → 2
nd Stabilizing, are included.
Examples
[0141] The invention is described in detail by examples below.
Example 1
[0142] A processing was run for 20 days until the sum of replenishing amount of stabilizing
replenishing solution is attained to 2 times of the volume of the stabilizing tank
in which Konica Color Negative Film Super DD100, imagewise exposed in a camera, was
processed. Steps and conditions of the processing were described below.

[0144] The fixing step was performed by a two-tank counter-current system (45 seconds for
each tank) and the stabilizing step was performed by a four-tank counter-current system
(15 seconds for each tank). The cross-over time for each tanks was 3 seconds respectively.
[0145] Composition of the processing solutions used are described below.

[0155] The processing was run in which the mount of ammonium thiosulfate and the additive
in the fixer and the fixer replenisher were changed as shown in Table 1, and the additive
in the stabilizer and the stabilizer replenisher was also changed as shown in Table
1.
[0156] After completion of running of the processing, condition of stain formed on the back
side of the film and that of the second stabilizing tank were observed. Further, the
amount of silver remained in the unexposed area of the film was determined by a fluorescent
X-ray method. Thus obtained results are shown in Table 1.

[0157] In the above, formalin is an aqueous solution of formaldehyde with a concentration
of about 38%. The norm of the evaluation was as follows.
<Evaluation of stain on the back surface of film>
[0158]
A: No stain was observed on the back surface of film.
B: A little stain was observed on the back surface.
C: A serious stain was observed on the back surface.
<Evaluation of condition of the second stabilizing bath>
[0159]
A: No change was observed in the second stabilizing tank
B: A little contamination was found in the tank
C: Sulfurization in the tank was apparently observed,
[0160] which causes a problem in practical use.
[0161] The amount of remaining silver not more than 3 mg/dm does not cause any problem in
practical use.

[0179] The following experiments were carried out using thus obtained film sample.
[0180] The experiments were carried out in the same manner as in Example 1 using the stabilizer
and the stabilizer replenisher used in Experiments Nos. 1 to 5 except that formalin
(5 ml/l) in the stabilizer and stabilizer replenisher was changed as shown in Table
2.
[0181] Processed film was stored in dark for 10 days at 75°C and a RH of 10%, and the difference
of the yellow transfer density at the unexposed area of the film was and that of the
film before the storage (or yellow stain) was determined.
[0182] Thus obtained results are shown in Table 2.

[0183] From the above results, it is understood that the formation of yellow stain at the
unexposed area is improved by making use of a compound represented by Formulas (F-1)
to (F-13) in the stabilizing solution.
Example 3
[0184] Experiments were carried out in the same manner as in Example 1 using the stabilizer
and the stabilizer replenisher used in Experiments Nos. 1 to 4 except that various
amount of sodium thiosulfate was added maintaining the total moles with ammonium thiosulfate
at a constant so that the ratio (mole %) of ammonium thiosulfate in the total thiosulfates
is varied as shown in Table 3. Further, an odor in the fixing solution in the fixing
tank was checked.

[0188] From the results in Table 3, it is understood that the effects of the invention are
enhanced when ammonium salt content in the thiosulfates is not more than 70 mole %
(particularly not more than 50 mole %, further specifically not more than 20 mole
%), and the odor is also improved so as to change the working environment for the
better.
Example 4
[0189] Experiments were carried out in the same manner as in experiments Nos. 1 to 7 except
that 450 ml/m of film of the stabilizing solution is pumped by a bellows pump from
the stabilizing tank provided at the position nearest to the fixing tank among the
four stabilizing tanks and poured into the fixing tank adjacent to the stabilizing
tank, and the concentration of the fixing replenisher was raised to two times and
the concentrated fixing replenisher was supplied to the second fixing tank in an amount
of 450 ml/m of film. The processing was run in the same manner as in Example 1. As
a result of that, the remaining amount of silver after the running became to zero
and a improvement in the stabilizing properties is established. The other properties
are the same as those obtained in Example 1. Further it is confirmed that the amount
of waste liquid formed by the photographic processing is reduced by about 21%.
[0190] Accordingly, it is understood that the effects of the invention are enhanced and
the total amount of waste liquid formed by the processing can be reduced by adding
a part or all of the stabilizing solution of the invention to the fixing tank.
Example 5
[0191] Experiments were carried out in the same manner as in Experiment Nos. 2 to 3 of Example
2 except that compound (1-10) in the fixer and compound (F-1-16) in the stabilizer
were was replaced by compounds described in Table 4.

[0192] From the above-mentioned, superiority of the method in which the fixing contains
a compound of the invention and the stabilizing solution contains substantially no
formaldehyde is established.
Example 6
[0193] Experiments were carried out in the same manner as in Experiments Nos. 1 to 6 of
Example 1 except that the receipts of the fixer and fixer replenisher were changed
as follows and the replenishing amount of stabilizer is changed as shown in Table
5. The stain on the back surface of the film was evaluated.

[0233] Fig. 3 shows a cross section of another supplying device for a solid processing composition,
which can be used processing composition in a form of granule or powder. In the supplying
device 70, a processing composition in a form of granule or powder is put into a hopper
71. A piston 75 is moved for horizontal (right) direction, according to the amount
of light-sensitive material processed, to put a prescribed amount of granules or powder
of processing composition into an amount measuring hole 72. Then the piston 75 is
moved for reverse (left) direction to supply the powdered or granulated processing
composition to a filter chamber through an exit hole 74. The device is adjusted so
as to supply 10 g of the powdered composition per time of supply.
[Granule method]
[0234] Granules prepared in operation (7) in Example 7 was used as fixer replenishing granules.
Supplying device for fixer replenishing granules
[0235] The supplying device of Fig. 1 used in Example 7 was replaced by that shown in Fig.

powdered and mixed so that the average particle size of the powder to be 30 µm. The
powder was granulated with 50 ml of water in a stirring granulating machine at a room
temperature for about 10 minutes. After granulation, the granules were dried at 60°C
for 120 minutes so that almost moisture contained in the granules was removed. The
dried granules were classified so that average size to be 800 µm and 50% of the granules
to be within a deviation range of ±200 µm to ±250 µm.
(II) Tableted fixer replenishing composition
[0240] The above obtained granules were mixed with 30 g of sodium N-lauroylsarcosine for
5 minutes in a mixing machine installed in a room conditioned at 25°C and a RH of
40% or less. The mixture was tableted by a tableting machine, modified Tough Press
Collect 1527UH, manufactured by Kikusui Seisakusyo, in a rate of 10 g per tablet.
Thus a tablet having a diameter of 30 mm and a thickness of 10 mm was prepared.
[0241] Thirty grams the above powder and granules, and three of the tablets were each sampled,
and the samples were each enclosed and shielded in a high-density polyethylene bag
having a size of 10 cm x 10 cm. The bags containing these samples were stored for
one month at 50°C and a RH of 50%.
[0242] Each of the samples was dissolved in water after the storage and was made to 100
ml. Thus obtained solutions were visually observed after stirring. Further the solutions
were filtered and the concentration of S₂O
3 2- in the filtrates were determined by reversal iodine titration method.
[0243] The above granulated processing composition stored for one month at 50°C and a HR
of 50% was taken out from the bag and sieved to remove particles each having a diameter
of not more than 149 µm and remained granules were weighed. The remained granules
were enclosed again in a polyethylene bag and shaken by a vibration testing machine
BF-UA manufactured by TDEX Co. with a shaking condition in which the sample was shaked
for 5 minutes while varying the shaking cycles 5 to 67 Hz and the shaking was repeated
for 24 times, 120 minutes in total. After the shaking test, the granules were sieved
again for removing particles of not more than 194 µm and remained granules were weighed.
The degree of powder formation during the storage in the granulated composition was
evaluated by the following equation. The tableted processing composition was evaluated
in the same manner in the above after storage at 50°C and a RH of 50% for 1 month.

[0244] The followings are evaluation ranks of the appearance of the solution in which the
solid processing composition after stored at the high temperature was dissolved, and

replenishing composition caused by decomposition of S₂O
3 2- during the prolonged storage can be prevented and deterioration in the solubility
of the composition and power formation in the composition can also be prevented by
applying the compound of the invention.
Example 11
[0256] Experiments and evaluations were carried out in the same manner as in Example 7 except
that the supplying amount of water, the supplying interval of solid composition and
the weight ratio of the addenda of the invention to thiosulfate were changed as shown
in Table 11. Thus obtained test results are shown in Table 11.

use of the compound of the invention and adjusting the ratio of the weight of the
compound to the weight of thiosulfate in the composition to the preferable range,
even when the concentration of thiosulfate is lowered. Further, the formation of scratch
and adhesion of smudge on the surface of the light-sensitive material, which are caused
by the crystals precipitated during storing the processing solution at a low temperature
and the substance precipitated on the surface of the transfer roller between the fixing
tanks, can also be prevented by making use of the compound of the invention and adjusting
