Abstract:
A photothermographic material containing a silver salt of an organic acid, a photosensitive silver halide, a reducing agent and a binder on a support, which contains at least one compound selected from compounds of the following Types (i) to (iv):Type (i) a compound of which one-electron oxidized derivative produced by one electron oxidation of the compound is capable of releasing two or more electrons with a bond cleavage; Type (ii) a compound of which one-electron oxidized derivative produced by one electron oxidation of the compound is capable of releasing one more electron with a bond cleavage and which has two or more groups adsorptive to silver halide in the molecule; Type (iii) a compound of which one-electron oxidized derivative produced by one electron oxidation of the compound is capable of releasing one or more electrons after undergoing a bond formation process; Type (iv) a compound of which one-electron oxidized derivative produced by one electron oxidation of the compound is capable of releasing one or more electrons after undergoing an intramolecular ring cleavage reaction.
