摘要： A heat-developable color photographic material is disclosed. The material is comprised of a support base, a binder, a light-sensitive silver halide, a dye releasing redox compound which reduces the light-sensitive silver halide and releases a hydrophilic dye by reacting with the light-sensitive silver halide by heating; and a base precursor. The base precursor is represented by the general formula: ##STR1## wherein the substituents are defined within the specification. The material is capable of forming dye images with high density by heating the material after exposure in a substantially water free state. The images can be obtained in a short period of time and maintain their color density during storage. Further, the material produces a relatively low degree of fog based on the high degree of image density obtained.
