ABSTRACT:
The heat development process using an integral color photographic recording material carrying, on a preferably transparent layer support, both an image receptor layer and light-sensitive layers of binder with silver halide and associated dye releasing compounds, optionally with a light-reflecting layer of pigment between the image receptor layer and the light-sensitive layers, may be carried out as a one-step development process in which silver halide development and color transfer take place at the same time if an auxiliary sheet containing a thermal development and diffusion promoting substance in a layer of binder is used. The thermal development and diffusion promoting agent is preferably liquid under normal conditions and dispersed in a microencapsulated form in the layer of binder.
