摘要： A photothermographic emulsion is prepared by chemically sensitizing silver halide grains formed by oxidative decomposition of a diphenylphosphine sulfide compound on or around the silver halide grains. This procedure uses a unique sequence of steps and provides increased photographic speed and manufacturing reproducibility.

摘要： 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.

摘要： The addition of certain aliphatic and non-aromatic carbocyclic polycarboxylic acids provides an improvement in natural age keeping properties of organic-solvent based photothermographic materials. This improvement is particularly useful in organic-based photothermographic materials containing phosphors in the photothermographic emulsion layer. Phosphor-containing materials can be particularly useful for direct radiographic imaging using X-radiation.
