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.
Claims14
A dry image-forming process which comprises image-wise exposing a light-sensitive silver halide material to radiation and transferring a dye imagewise formed as a consequence of the image-wise exposing, wherein the silver halide light-sensitive material comprises a support having thereon a light-sensitive silver halide, a binder and a dye-forming compound which forms the dye in a chemical reaction of the dye-forming compound upon a reduction reaction of the exposed silver halide to silver by heat development of the light-sensitive material into a dye-fixing layer of a dye-fixing material having a mordant and a thermal solvent in an amount of 20 to 200% by weight of the total coating amount for the light-sensitive material and the dye-fixing material at high temperature at which the thermal solvent is in a molten state, wherein said dye-fixing material contains at least one of a base and a base precursor.
