ABSTRACT:
A process of forming images with a heat-developable color light-sensitive material is disclosed. The process of forming images comprises steps of exposing imagewise a heat-developable color light-sensitive material which comprises a support having thereon a light-sensitive layer containing a binder, light-sensitive silver halide emulsion and dye donating substance capable of forming or releasing a diffusible dye upon heat development and superposing a dye image receiving material which comprises a support having thereon a dye receiving layer, over the light-sensitive material during, or after completion of, heat development to transfer dye images to said dye image receiving layer; wherein the dye image receiving layer contains a hydrophilic binder and polymer particles; a weight ration of the hydrophilic binder to the polymer particles is from 1:05 to 1:20; and the heat development and transfer of dye images to the dye image receiving layer are carried out in the substantial absence of water.
