Organic solvent-based photothermographic materials comprise one or more mercaptotriazoles represented by the following Structure I as toner(s): wherein R1 and R2 independently represent hydrogen, or an alkyl, aryl, aralkyl, alkenyl, cycloalkyl, or aromatic or non-aromatic heterocyclyl group, M is hydrogen or a cation, or R1 and R2 taken together can form a saturated or unsaturated heterocyclic ring, or still again, R1 and R2 taken together can represent a divalent linking group, provided that R1 and R2 are not simultaneously hydrogen or an unsubstituted phenyl group, and further provided that when R2 is hydrogen, R1 is not a methyl or phenyl group having a solubilizing substituent.
