Abstract
A heat-developable color photographic material is disclosed. The material is comprised of a support having thereon a layer containing fine droplets of complex coacervate containing a light-sensitive silver halide, an organic silver salt oxidizing agent and a color image forming substance which are prepared by complex coacervation and hardened with a hardening agent. Color fog does not occur with the material and it can be easily prepared to provide a color image having good color balance by imagewise exposure to light and a heat development procedure. A process for forming a color image using the heat-developable color photographic material is also disclosed.
