Estimating the term…
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.
A light-sensitive color photothermographic imaging element comprising at least one pyrrolotriazole coupler in reactive association with a developer, or developer Visor that liberates a developing agent, wherein the pyrrolotriazole coupler and the developing agent have the property that it is capable of forming a reaction product that is an infrared dye with a λmax of greater than 700 nm.
A method of processing an imagewise exposed photothermographic element comprising a plurality of recording layer units, which method comprises thermally developing the imagewise exposed photothermographic element to form an image and then scanning the element to form an electronic image representation of the developed image in the element, wherein at least one image recording layer in at least one of the recording layer units comprises an infrared dye that is the reaction product of a pyrrolotriazole coupler and a developer, or developer precursor that liberates a developer, wherein the infrared dye has a λmax of greater than 700 nm.
