ABSTRACT:
The invention discloses an aqueous-developable chromogenic photographic heat-transferable non-aqueous dye-diffusion-transfer photographic element comprising radiation sensitive silver halide, a dye-providing compound that forms or releases a heat-transferable, image dye upon reaction of said compound with the oxidation product of a primary amine developing agent, a hydrophilic binder, and a thermal solvent for facilitating non-aqueous diffusion transfer wherein said thermal solvent comprises a sugar group containing amphiphilic compound, said amphiphilic compound comprising from one to three independently constituted 3 to 22 carbon atom hydrophobic tail(s) with one or more attached hydrophilic mono or oligosaccaridic rings or chains such that the HLB value of the compound is less than about 13.
