ABSTRACT:
A photographic silver halide emulsion containing a yellow color forming coupler, in which one hydrogen atom of an active methylene group is replaced by a 2,5-dioxo-1-imidazolidinyl group, in which a nitrogen atom at 3-position and a carbon atom at 4-position are connected to form a ring through a divalent aliphatic radical, a photographic element containing the emulsion and a method for forming color photographic images which comprises developing the image-exposed photographic silver halide emulsion with a primary aromatic amino developing agent. These yellow color forming couplers have a high coupling reactivity as well as no adverse effect on the bleaching of developed silver and thus they are suitable for use in rapid processing type color photographic materials.
