Abstract:
Supersensitization of photothermographic silver halide emulsions is effected by the addition of a metal chelating agent to a photothermographic emulsion which is or becomes spectrally sensitized.

Abstract:
Addition of a surfactant to either the under-layer, the image-receiving layer, or to both the under-layer and the image-receiving layer provides a quick-drying, transparent ink-jet recording film capable of achieving an optical density of at least 2.8 while still having a low haze and producing a number of grey levels.
Abstract:
Photothermographic materials are designed with increased photospeed by chemical sensitizing the photosensitive silver halide grains with a combination of compounds. A first chemical sensitizer is a specific gold(III)-containing compound and a second chemical sensitizer is a sulfur-containing compound that is a diphenylphosphine sulfide. The molar ratio of the gold(III)-containing compound to the sulfur-containing compound is at least 1:1.
Abstract:
A photothermographic emulsion is prepared by chemically sensitizing silver halide grains by oxidative decomposition of an organic sulfur-containing compound on or around the silver halide grains. This procedure uses a unique sequence of steps and provides increased photographic speed and manufacturing reproducibility. The resulting photothermographic emulsion can be used to prepare photothermographic materials.
