Abstract

Abstract:

The effectiveness of chemical sensitization technology in conventional silver halide photography, like sulfer sensitization, gold sensitizatin, sufer-plus-gold sensitization, was researched for photothermographic materials using silver benzotriazole as silver source and water-coated polyvinyl alcohol as binder. It was found that conventional chemical sensitization used in ex-situ method photothermographic materials with silver bromide as photosensitizer had a good impact in improving the sensitivity, and the sulfur- plus-gold sensitization has the best effection. However, conventional chemical sensitization used in in-situ method photothermographic materials reduced the sensitivity, and the sulfur- plus-gold sensitization reduced most seriously.

Key words: photothermographic material, silver benzotriazole, photosensitizer, sensitivity, chemical sensitization
