Abstract:
1. A black-and-white organic solvent-based photothermographic material that comprises a support having thereon one or more thermally developable imaging layers comprising a hydrophobic binder and in reactive association, a preformed photosensitive silver halide, a non-photo-sensitive source of reducible silver ions that is a silver salt of a long-chain aliphatic carboxylic acid or a mixture thereof, and including at least silver behenate, a reducing composition for said non-photosensitive source of reducible silver ions that consists essentially of one or more hindered phenols, and in one or more of said thermally developable imaging layers, one or more mercaptotriazoles represented by the following Structure I as toner(s): wherein R 1 and R 2 independently represent hydrogen, or an alkyl, aryl, aralkyl, alkenyl, cycloalkyl, or aromatic or non-aromatic heterocyclyl group, M is hydrogen or a cation, or R 1 and R 2 taken together can form a saturated or unsaturated heterocyclic ring, or still again, R 1 and R 2 taken together can represent a divalent linking group, provided that R
