ABSTRACT:
A dry image-forming process is disclosed which comprises transferring a mobile hydrophilic dye formed imagewise at exposure areas of a heat developable light-sensitive material comprising a support having thereon at least a light-sensitive silver halide, a hydrophilic binder, a reducing agent for the silver halide, and a non-diffusible 2-equivalent coupler by heating the light-sensitive material after imagewise exposure or simultaneously with imagewise exposure in the presence of a hydrophilic thermal solvent at a high temperature at which the hydrophilic thermal solvent is in a molten state without supplying a solvent from the outside, and fixing the dye in a dye-fixing layer.
