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.
