Abstract
Abstract A silver halide light-sensitive color photographic material comprising a blue-sensitive, a green-sensitive and a red-sensitive negative type light-sensitive silver halide emulsion layers provided on a support, at least 80% of the silver halide grains contained in the light-sensitive silver halide emulsion layer farthest from said support or in the green-sensitive silver halide emulsion layer being constituted by regular-crystal silver halide grains. The color photographic material according to the present invention exhibits an improved sharpness of the dye image formed therein.
