Abstract: Chemical sensitization of silver halide photothermographic emulsions used in photothermographic elements, can be effected by the decomposition of sulfur containing compounds on or around the surface of the silver halide grains, usually under oxidizing conditions at elevated temperatures. Alignment of the sulfur containing compounds on the surface of the grains, can be accomplished with spectral sensitizing dyes and appears to be particularly effective in providing strong chemical sensitization effects.
Abstract translation: 用于光热敏成像元件的卤化银光热敏成像乳剂的化学增感可以通过在卤化银晶粒表面上或周围分解含硫化合物，通常在高温下的氧化条件下进行。 颗粒表面上的含硫化合物的排列可以用光谱增感染料实现，并且在提供强烈的化学增感效果方面似乎特别有效。
