Photothermographic materials incorporating antifoggants

摘要

Incorporation of certain compounds into photothermographic materials provides materials with reduced initial image D_min and improved Raw Stock Keeping film stability without unacceptable loss in sensitometric properties. These compounds include certain e-i) zinc salts of an aryl sulfonic acid or of a fluorinated C₂-C₆ carboxylic acid, e-ii) non-encapsulated alkali metal salts of an aryl sulfonic acid or of a fluorinated C₂-C₆ carboxylic acid, and e-iii) fluorinated C₂-C₆ carboxylic acids.
