ABSTRACT:
A method of forming color photographic images which comprises developing an image-exposed photographic silver halide emulsion layer with a primary aromatic amino color developing agent in the presence of a yellow color forming coupler, in which one hydrogen atom of an active methylene group is substituted with a 5-alkylidene-3-hydantoinyl group and a color photographic light-sensitive element which comprises a silver halide emulsion containing a yellow color forming coupler, in which one hydrogen atom of an active methylene group of the coupler is substituted with a 5-alkylidene-3-hydantoinyl group. These yellow color forming couplers have a high coupling reactivity and additionally provide a stable coupler dispersion.
