Abstract
Abstract A silver halide multilayered color photographic light-sensitive material is disclosed. The material is comprised of a support basde having thereon a green-sensitive emulsion layer having a maximum sensitivity of from 535 nm to 555 nm, a blue-sensitive emulsion layer having a maximum sensitivity in the range of 80 to 110 nm shorter than that of the green-sensitive layer and a red-sensitive layer having a maximum sensitivity in the range of 75 to 95 nm longer than that of the green-sensitive layer. The material also contains a compound capable of releasing a diffusible development inhibitor or its precursor by a coupling reaction with the oxidation product of a color developing agent. This compound is present within one of the emulsion layers or a light-insensitive layer adjacent to one of the silver halide emulsion layers. The material undergoes less changes in color reproducibility due to changes in color temperature of a light source upon photographing. Further, the material can reproduce color with high saturation and high fidelity.
