ABSTRACT:
An aqueous-developable chromogenic photographic heat-transferable non-aqueous dye-diffusion-transfer photographic element is disclosed, wherein said element comprises 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 according to formula (I) ##STR1## wherein AH is a hydrogen bond donating group with an aqueous pK.sub.a value for proton loss of greater than 6;
