    摘要： 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.

    摘要： A photothermographic composition of enhanced photosensitivity is disclosed prepared by a process of (a) precipitating light-sensitive silver halide grains in the presence of a non-aqueous polymeric peptizer and (b) then combining the silver halide grains with a non-aqueous polymeric vehicle containing an oxidation-reduction image-forming combination comprised of an organic silver compound and a reducing agent for the organic silver compound. Light-sensitivity of the silver halide grains is enhanced by, prior to step (b), sensitizing the silver halide grains with a 1,1,3,3-tetra-substituted thiourea or selenourea having an acid dissociation constant of less than 7.0, the thiourea or selenourea being dissolved in an aqueous medium.

    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.
