ABSTRACT:
A color image is formed by imagewise exposing a photosensitive material comprising at least (a) a photosensitive silver halide, (b) a binder, (c) a dye-providing substance which forms or releases a diffusible dye in response or counter-response to the reduction of the silver halide into silver at elevated temperatures, and (d) a specific-surface-active agent on a support, and heat developing the photosensitive material to form an image.
