A heat developable color light-sensitive material is disclosed. The material is comprised of a support base having thereon a light-sensitive silver halide, a binder, a dye-releasing material and a base precursor. The dye-releasing material is reductive to the light-sensitive silver halide and releases hydrophilic dye by causing a reaction with the light-sensitive silver halide by heating. The base precursor is a compound represented by the general formulae (A) and/or (B): ##STR1## wherein the substituents are defined within the specification. The material is capable of forming images by heating in a substantially water free state in order to provide high-density color images in a short period of time. The images formed have a decreased amount of fogging and higher density as compared with conventional materials. Further, the disclosed material has excellent stability when stored.
