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 method of scanning silver-halide-containing color photographic and photothermographic film. In particular, the present invention comprises a photographic element comprising at least one infrared imaging dye-forming agent in a blue-sensitive color layer of the element, thereby forming at least one image record in the infrared region of the imagewise exposed and developed element. This expedient leads to the formation of high quality images when scanning photographic elements in which the silver halide, metallic silver, and/or any organic silver salts have not been removed.

Abstract: A light-sensitive silver-halide color photothermographic element comprises a typically magenta dye-forming pyrazolone coupler in the cyan record by rendering the hue of the resultant dye a cyan hue. The use of certain para-phenylenediamine developers, for example, containing a substituent group in both the 2- and 6-positions (ortho, ortho') relative to the coupling nitrogen, along with selected magenta dye-forming couplers, when oxidized, yield cyan dyes with certain couplers, resulting in the superior non-hue characteristics of magenta couplers in the cyan layer. By means of the present invention, light sensitive color photothermographic elements can form image dye records of consistent density forming ability and consistent stability in all three color records. Also disclosed is a method of processing such a color photographic element.

Abstract: Non-photosensitive direct thermographic materials comprise a reducing agent that is a specific ortho-amino-phenol, para-amino-phenol, or hydroquinone compound. These compounds can reduce silver(I) ion to metallic silver to produce a dense black silver image under the short time and high temperature conditions that occur when using thermal print-heads during direct thermal printing. The materials are characterized by their calculated aqueous deprotonation and their calculated anion HOMO energies.
