Beschreibung
Zusammenfassung:	A photothermographic element and composition for providing a dye image comprises (a) photographic silver halide in association with (b) an oxidation-reduction image-forming combination comprising (i) a silver salt oxidizing agents with(11) an organic reducing agent, (c) a polymeric binder for the element or composition and (d) a leuco-base dye which is oxidizable to form a dye image. After imagewise exposure of a photothermographic element or composition containing the described combination, a color image can be developed by overall heating the photothermographic element. Negative or positive dye images can be provided. The dye image can be transferred to an image receiver.
