Abstract

A color photographic recording material comprising a support and at least one photosensitive silver halide emulsion layer, with which a yellow coupler of the pivaloyl or benzoyl acetanilide type dissolved in a polymeric ester of aromatic or aliphatic dicarboxylic acids is associated, is distinguished by greater color purity and better dark-fading stability.
