A color photographic silver halide material comprising a substrate, at least one red-sensitive silver halide emulsion layer containing at least one cyan coupler, at least one green-sensitive silver halide emulsion layer containing at least one magenta coupler and at least one blue-sensitive silver halide emulsion layer containing at least one yellow coupler, characterised in that the silver halide crystals of the red-sensitive layer have a chloride content of at least 95 mol %, the cyan coupler corresponding to formulawhereinR<1 >represents a hydrogen atom or an alkyl group,R<2 >represents an alkyl, aryl or hetaryl groupR<3 >represents an alkyl or aryl group,R<4 >represents an alkyl, alkenyl, alkoxy, aryloxy, acyloxy, acylamino, sulphonyloxy, sulphamoylamino, sulphonamido, ureido, hydroxycarbonyl, hydroxycarbonylamino, carbamoyl, alkylthio, arylthio, alkylamino or arylamino group or a hydrogen atom andZ represents a hydrogen atom or a group which may be split off under the conditions of chromogenic development andthe red-sensitive layer contains at least one compound of formulawhereinR<5 >represents H, CH3 or OCH3,R<6 >represents H, OH, CH3, OCH3, NHCO-R<7>, COOR<7>, SO2NH2, NHCONH2 or NHCONH-CH3 andR<7 >represents C1 to C4 alkyl,is distinguished by very good stability in storage simultaneously with very good latent image stability.
