Abstract
A heat-developable color photographic material is disclosed. The material is comprised of a support having thereon a layer containing at least a light-sensitive silver halide and the photographic material containing an organic silver salt, a binder, a dye releasing activator and a dye releasing redox compound which releases a diffusible dye. The improvement comprises a support capable of receiving a released dye or a support having thereon a layer composed of an organic high molecular weight compound capable of receiving a released dye. The heat-developable color photographic material can easily provide a clear and stable color image by imagewise exposure to light and heat development procedure. A method of forming a color image using the heat-developable color photographic material is also disclosed.
