ABSTRACT:
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.
