Patent number: 6576414Abstract: 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 lower pKsp relative to the organic silver salt in the core. This invention also provides a composition comprising the core/shell non-photosensitive organic silver salt particles, and a method of making the particles.Type: GrantFiled: November 21, 2001Date of Patent: June 10, 2003Assignee: Eastman Kodak CompanyInventors: Mark E.

Publication number: 20020132175Abstract: The present invention is directed to a method of scanning silver-halide-containing color photographic and photothermographic film. In particular, the present invention comprises record shifting by means by employing at least one infrared dye in a color unit of the film, thereby forming at least one image record in the infrared. 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.Type: ApplicationFiled: March 6, 2002Publication date: September 19, 2002Applicant: Eastman Kodak CompanyInventor: Richard P.
