Abstract:
The present invention is directed to a photothermographic element comprising at least one imaging layer with a pyrrolotriazole coupler and a developing agent, or precursor thereof, the combination of which is capable of forming an image record in the infrared region of the light spectrum in response to a selected hue of visible light. This expedient leads to the formation of high quality images, especially when scanning photothermographic elements in which the silver halide, metallic silver, and/or any organic silver salts have not been removed. Also disclosed is a method for photothermographically forming a developed image comprising an infrared image record.
