A process is disclosed for forming an improved dye image in an aqueous-developable photographic dry dye-diffusion transfer element comprising the steps of: providing an aqueous-developable chromogenie photographic dry dye-diffusion transfer element comprising radiation sensitive silver halide, an aqueous-developable material containing color coupler wherein said coupler forms or releases a heat-transferable dye upon reaction of said coupler with the oxidation product of a primary amine developing agent, a hydrophilic binder, and a thermal solvent wherein said thermal solvent has the structure I <IMAGE> (I) wherein (a) Z1, Z2, Z3, Z4, and Z5 are substituents, the Hammer sigma parameters of Z2, Z3, and Z4 sum to give a total, SIGMA , of at least -0.28 and less than 1.53; (b) the calculated IogP for I is greater than 3 and less than 10; exposing said dye-diffusion transfer element to actinic radiation; contacting said dye-diffusion transfer element with an aqueous-developing solution, wherein said aqueous-developing solution comprises a primary amine developing agent; contacting said dye-diffusion transfer element with an aqueous stop bath; drying said dye-diffusion transfer element; providing a dye-receiving layer and contiguous support, where said dye-receiving layer is in physical contact with said dye-diffusion transfer element; heating said dye-diffusion transfer element and dye-receiving layer to effect dye-diffusion transfer; and separating said dye-receiving layer and contiguous support from said dye-diffusion transfer element.
