ABSTRACT:
Improved color graininess can be obtained with a color photographic recording material containing in association with a silver halide emulsion layer unit a non-diffusing colored color coupler which, in the coupling position, contains a diffusion-proofing primary ballast group which is attached through an azo group and which is releasable during the color coupling reaction and which coupler gives a hydrophobic dye of limited mobility in the color coupling reaction.
