ABSTRACT:
A diffusion transfer heat-developable color photographic material comprising a support having thereon a layer containing at least a light-sensitive silver halide, and the photographic material containing an organic silver salt oxidizing agent, a reducing agent, a hydrophobic binder and a dye releasing coupler which releases a diffusible dye upon heat development. The diffusion transfer heat-developable color photographic material can provide a stable color image by imagewise exposure to light and heat development procedure. A method of forming a color image using the diffusion transfer heat-developable color photographic material is also disclosed.
