发明名称 Process for forming color photographic images
摘要 A process for forming color photographic images having improved granularity, sharpness, and gradation by applying, after image exposure, a color reversal process including a step of performing color development in the presence of a competing coupler. The element processed is a multilayer reversal color photographic material comprising a support having coated thereon at least three differently sensitive photographic silver halide emulsion layers, the outermost layer of the color photographic material being blue-sensitive and containing a nondiffusible coupler forming a yellow dye by a coupling reaction with an oxidized primary aromatic amino color developing agent and represented by the following general formula (I) <IMAGE> (I) wherein R1 represents an alkyl group or an aryl group; R2 represents an aryl group or a heterocyclic group; and Z represents a non-metallic atom or the non-metallic atoms required to form a 4-membered ring, a 5-membered ring, or a 6-membered ring together with the <IMAGE> moiety, one of the other two layers being green-sensitive and containing a nondiffusible coupler forming a magenta dye by a coupling reaction with an oxidized primary aromatic amino color developing agent, and the other layer being red-sensitive and containing a nondiffusible coupler forming a cyan dye by a coupling reaction with an oxidized primary aromatic amino color developing agent.
