ABSTRACT:
Disclosed is a light-sensitive silver halide color photographic material comprising at least one light-sensitive layer, which is constituted of a plurality of silver halide emulsion layers having substantially the same color sensitiveness but being different in sensitivities and contains a dye image-forming coupler, provided by coating on a support, said material being constituted so as to satisfy at the same time the requirements that (a) said plurality of silver halide emulsion layers in said light-sensitive layer are provided by coating in the order from the support side a low sensitivity emulsion layer, medium sensitivity emulsion layer and high sensitivity emulsion layer, (b) a non-sensitive intermediate layer is provided by coating between said low sensitivity emulsion layer and said medium sensitivity emulsion layer, (c) the density of a dye image-forming coupler in said medium sensitivity emulsion layer is 10 to 60% of the density of a dye image forming coupler in said low sensitivity emulsion layer; and (d) the maximum color-formed density (D) in said medium sensitivity emulsion layer is 0.6<D<1.2.
