ABSTRACT:
A diffusion transfer heat-developable color photographic material. The material comprises a support, a photosensitive silver halide, an organic silver salt, a hydrophobic binder, a dye releasing activator, and a dye releasing redox compound which releases a diffusible dye. Color images are obtained with the material by transferring a dye released by heat development. The material makes it possible to obtain clear color images by a simple procedure and the images obtained are stable over a long period of time.
