ABSTRACT:
A process which comprises transferring a dye imagewise formed on a silver halide light-sensitive material comprising a support having thereon a light-sensitive silver halide, a binder and a mobile dye-forming compound which forms a dye in a chemical relation of the compound upon a reduction reaction of the silver halide to silver by a heat development of the light-sensitive material after or simultaneously with an image exposure, into a dye fixing layer in the presence of a thermal solvent at a high-temperature at which the thermal solvent is in a molten state. The process can be conducted without supplying solvent from the outside.
