ABSTRACT:
An aqueous developable chromogenic photographic dye-diffusion transfer element of two or more layers comprising a support, radiation sensitive silver halide, a dye-forming compound wherein said compound forms a heat transferable dye upon reaction of said compound with the oxidation product of a primary amine developing agent, a hydrophilic binder, and a solid particle thermal solvent dispersion, wherein said thermal solvent is a water-immiscible phenol derivative, has a melting point of between 50.degree. C. and about 200.degree. C., and is incorporated at 5 to 200% by weight of said hydrophilic binder, and where said thermal solvent dispersion contains a dispersing aid, is disclosed.
