Abstract: A method of processing photographic color papers is carried out using a photographic bleach-fixing composition in a bleach-fixing step that is carried out for less than 60 seconds. The bleach-fixing composition comprises certain aliphatic or aromatic sulfur-containing compounds that include a —N═C(SH)— group. The bleach-fixing composition can be prepared from a two-part bleach-fixing kit having two solutions that can be added directly to a processing chamber or premixed to form a replenisher solution.

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.
