ABSTRACT:
A heat-developable color light-sensitive material is described, comprising a support having thereon at least (1) a light-sensitive silver halide emulsion, (2) a dye providing substance which releases a dye having a different diffusibility from that of the dye providing substance in correspondence or countercorrespondence to the light-sensitive silver halide when the light-sensitive silver halide is reduced under the condition of high temperature and (3) an organic acid precursor containing a structural moiety bonded to carbon atoms that is represented by formula (I) ##STR1## The heat-developable color light-sensitive material can provide color images having a high S/N ratio and a high image density.
