Abstract
A light-sensitive color photographic material with improved color reproducibility which comprises on a support a plurality of light-sensitive silver halide emulsion layers including a red-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer, a blue-sensitive silver halide emulsion layer and at least one silver halide emulsion layer having reverse photo-response to that of the red-, green-, and blue-sensitive silver halide emulsion layers, being capable of forming a reverse dye image having substantially the same hue as that is to be formed in the green-sensitive silver halide emulsion layer, and having maximun sensitivity wavelength (.lambda.-G) of the spectral sensitivity distribution in the region of from 400nm to 500nm.
