Abstract

Abstract A silver halide colour pyhotographic light-sensitive material is disclosed. The photographic material comprises a support having thereon photographic component layers including a red-sensitive emulsion layer containing a cyan coupler, a green-sensitive emulsion layer containing a magenta coupler and a blue-sensitive emulsion layer containing a yellow coupler and at least one of these silver halide emulsion layers contains a diffusible DIR compound, wherein the total dry-thickness of the photographic component layers is not thicker than 16 µm and the whole silver halide content of the silver halide emulsion layers is not more than 6.5 g/m² in terms of silver and, a colloidal layer, formed in a position farther from the support than the silver halide emulsion layer which are farthest from the support, contains substantially non-light-­sensitive fine grain silver halide grains. The photographic material is improved in sharpness and color reproduction.
