ABSTRACT:
There is disclosed a heat-developable color photographic light-sensitive material having on a base at least a light-sensitive silver halide, a binder, a coupler, and a reducing agent, wherein, as the reducing agent, a co-emulsion comprising at least one silver-developing reducing agent and at least one color-image-forming reducing agent is contained, and the silver-developing reducing agent is a specific sulfonamidophenol compound, and wherein the coupler forms a diffusion dye by reaction with an oxidized product of the color-image-forming reducing agent. The light-sensitive material can secure good discrimination by rapid processing and it is excellent in raw stock storability.
