ABSTRACT:
A heat-developable diffusion transfer color photographic material is disclosed. The material is comprised of a heat-developable color photographic element containing at least a light-sensitive silver halide, an organic silver salt oxidizing agent and a color image forming substance and an image receiving element capable of accepting a dye which is formed or released in the heat-developable color photographic element, the heat-developable color photographic element and the image receiving element being provided on the same support or being provided on different supports respectively, and either one of these elements or both of these elements contain a microcapsule comprising a water-immiscible compound which is liquid at a temperature of not less than 120.degree. C. as a core material and a water-insoluble polymer wall.
The heat-developable diffusion transfer color photographic material contains a diffusion accelerator for the dye in the microcapsule and can easily provide a transferred color image without adversely affecting the coating property and physical property of the light-sensitive element.
A process for forming a color image using the heat-developable diffusion transfer color photographic material is also disclosed.
