Abstract:
An aqueous developable chromogenic photographic element for non-aqueous thermal dye-diffusion transfer comprising 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 thermal solvent for facilitating non-aqueous thermal dye diffusion transfer wherein said thermal solvent has the structure I ##STR10##wherein(a) Z.sub.1, Z.sub.2, Z.sub.3, Z.sub.4, and Z.sub.5 are substituents, the Hammet sigma parameters of Z.sub.2, Z.sub.3, and Z.sub.4 sum to give a total, .SIGMA., of at least -0.28 and less than 1.53;(b) the calculated logP for I is greater than 3 and less than 10;with the proviso that said heat transferable dye formed upon reaction of said compound with the oxidation product of a primary amine developing agnt transfers at a temperature of from about 50.degree. C. to 200.degree. C.
