Abstract (en)

A silver halide color photographic material is disclosed. The material is comprised of a support base having a red-sensitive, green-sensitive and blue-sensitive 3 silver halide emulsion layers positioned thereon. One of the silver halide emulsion layers is comprised of a plurality of silver halide emulsion layers which include a highest-sensitive layer containing a high reaction rate coupler and a low sensitive layer containing a relatively low reaction rate coupler having a reaction rate in a range of 1/1.3 to 1/15 of that of the high reaction rate coupler and a diffusible DIR compound. The material of the invention can be exposed and developed to form an image which simultaneously has improved granularity and sharpness.
