Dry image-forming process |
(57) A dry image-forming process is disclosed. The dry image-forming process of the invention
comprises heat developing a light-sensitive material comprising a support having thereon
at least a photosensitive silver halide, a binder, and a dye releasing redox compound,
said dye releasing redox compound being reductive to the photosensitive silver halide
and being capable of releasing a hydrophilic dye upon reaction with the photosensitive
silver halide under heating, after or simultaneously with imagewise exposure, to form
imagewise a mobile hydrophilic dye and heating, after simultaneously with the heat
development, the light-sensitive material together with a dye-fixing layer in the
presence of a hydrophilic thermal solvent to thereby transfer the mobile hydrophilic
dye onto the dye-fixing layer to form a dye image and fix the dye image. The heat
development is carried out in a state containing substantially no water, and the whole
of steps are carried out without particular supplying a solvent.
