Abstract (en)
[origin: EP0329016A2] A colour-photographic recording material consisting of a base and at least one silver halide emulsion layer applied to a base, and associated with at least one colour coupler having a coupling rate constant at pH = 10.2 and 38 DEG C of >/=10<4> [l/mol x sec] and at least one DIR coupler having a coupling rate constant at pH = 10.2 and 38 DEG C of >/= 10<4> [l/mol x sec], wherein a silver halide emulsion is used which, with the abovementioned colour couplers and DIR couplers, gives at 38 DEG C in a colour developer of the following composition sodium tripolyphosphate 2.0 g sodium sulphite (anhydrous) 2.0 g sodium hydrogen carbonate 8.0 g potassium or sodium hydrogen sulphate 7.0 g potassium bromide 1.8 g potassium or sodium carbonate (anhydrous) 30.0 g hydroxylamine sulphate 3.0 g N<1>-ethyl-N<1>-(2-hydroxyethyl)-3-methyl-1,4-phenylenediammonium sulphate (monohydrate) 2.6 g water to make up to 1000 ml pH = 10.2 a relative maximum colour density = <IMAGE> of at least 50 %, shows a small range of variation with respect to sensitometric data (sensitivity, gradation and fog) in the event of variations of the processing conditions.
