    摘要： This invention comprises a thermally processable element comprising at least one imaging layer on a support, wherein the imaging element also comprises at least one photographically useful reducing agent ionically bound to an ion exchange matrix. The imaging element preferably is a photothermographic element in which the imaging layer comprises a light sensitive silver halide, an oxidizing agent, preferably an organic silver salt, and a reducing agent. The invention also comprises developing said photothermographic element by heating the element to a temperature above about 50° C. The invention also comprises a methods of forming an image by scanning the developed photothermographic element.

    摘要： The present invention is directed to the use of a mixture of non-light sensitive organic silver salts in a color photothermographic system comprising a blocked developing agent for color imaging. At least one of the organic silver salts is the sole or primary silver donor during thermal development and at least one other organic silver salt, present at levels in the range of 30,000 to 60,000 mg/mol of silver halide, effectively inhibits fog during thermal development of the photothermographic element. In one embodiment, and the system comprises a mixture of at least two organic silver salts, wherein the first organic silver salts exhibits a cLogP of 0.1 to 10 and a Ksp of 7 to 14 and wherein the second organic silver salt exhibits a cLogP of 0.1 to 10 and a Ksp of 14 to 21.

    摘要： This invention relates to packaged photographic film that is capable of being alternately processed, according to individual consumer choice, by either (1) a traditional wet-chemistry process with a phenylenediamine-containing developer solution followed by desilvering in one or more subsequent solutions to obtain a color negative film, or (2) a thermal process involving the use of a relatively minor amount of an aqueous solution containing a liberating agent such as alkaline base to activate (unblock) a blocked phenylenediamine developing agent located within the photographic element, followed by electronic scanning of the developed film without desilvering. This invention enables a single film stock to be developed in both a conventional deep tank process and in an apparently dry process.
