ABSTRACT:
A silver halide color photographic light-sensitive material is disclosed. The material is comprised of a support base having a plurality of silver halide emulsion layers positioned thereon. The material includes at least one silver halide emulsion layer having a particular sensitivity and color sensitivity, and a second silver halide emulsion layer having the same color sensitivity but having a greater sensitivity with respect to light, the second layer including a silver halide having a silver iodide content in the range of 9% by mol to 15% by mol. The material includes a DIR compound in a layer other than the second silver halide emulsion layer. The DIR compound releases a diffusible development inhibitor or precursor thereof by a coupling reaction. The resulting material has greatly improved granularity and sharpness.
