ABSTRACT:
A photothermographic element comprises a combination of certain energy sensitive organic dyes capable of forming or destroying an active spcies upon selective exposure to actinic radiation to give a positive or negative image after heat development of the element. The element also comprises an oxidation-reduction image-forming composition comprising a silver salt oxidizing agent and a non-radiation sensitive organic reducing agent.
