Publication number: 20030073044Abstract: 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.Type: ApplicationFiled: August 13, 2001Publication date: April 17, 2003Inventors: James H. Reynolds, Leif P. Olson, Wojciech K. Slusarek, David H. Levy

Patent number: 6548236Abstract: The present invention is directed to a photothermographic element comprising silver halide, a blocked developer, a coupler, and core/shell particles, each such particle comprising a mixture of at least two non-photosensitive organic silver salts, which particle comprises a center portion comprising a non-photosensitive first organic silver salt and at least one shell portion covering the center portion, the shell comprising a non-photosensitive second organic silver salt. The organic silver salt in the shell has a higher pKsp relative to the organic silver salt in the core. This invention also provides a composition comprising core/shell non-photosensitive organic silver salt particles, and a method of making the particles.Type: GrantFiled: November 21, 2001Date of Patent: April 15, 2003Assignee: Eastman Kodak CompanyInventors: Mark E. Irving, David H. Levy, JoAnn D. Hanna, Stephen Swingley, Donald L. Black, Stephen C. Stoker
