ABSTRACT:
A heat developable color light-sensitive material is disclosed, which comprises a support having provided thereon at least a light-sensitive silver halide emulsion, a binder, and a compound having a dye moiety within the molecule and which is capable of releasing, upon reduction of light-sensitive silver halide to silver at elevated temperatures, said dye moiety corresponding to or inversely corresponding to the reduction to form a dye different from said compound in terms of diffusibility, wherein said light-sensitive silver halide emulsion is prepared by forming silver halide grains in the presence of a sensitizing dye.
