ABSTRACT:
A negative-acting photothermographic element comprises a support bearing at least one heat-developable, photosensitive, image-forming photothermographic emulsion layer that contains photosensitive silver halide grains doped with iridium and copper; a non-photosensitive, reducible source of silver; a reducing agent for the non-photosensitive, reducible source of silver; and a binder. A process of forming photothermographic emulsions from doped silver halide grains by forming silver soaps in the presence of those grains is also described.
