Abstract (en)
A silver halide color photographic material light-sensitive is disclosed. The light-sensitive material comprises a red-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer and a blue-sensitive silver halide emulsion layer. The light-sensitive material satisfise the following requirements: (1) at least one of the red-sensitive emulsion layer and the green-sensitive emulsion layer comprises two or more emulsion sub-layers, (2) an emulsion sub-layer having the highest speed among the emulsion sub-layers contains silver halide grains having a volume average size of from 0.20 mu m to 0.55 mu m, (3) the light-sensitive material contains a diffusible DIR compound capable of splitting of a development inhibitor or its precursor which has a diffusibility not less than 0.34, and the amount of the DIR compound satisfise the following equation: A/B >/= 5.00 x 10<-><7> mole/cm<2> wherein A is the sum of molar amount of the diffusible DIR compound contained in one square meter of the light-sensitive material, and B is sum of the surface area of light-sensitive silver halide emulsion grains contained in one square meter of of the light-sensitive material represented by cm<2>. The light-sensitive material is improved in graininess, sharpness and color reproducibility. x
