Abstract
Disclosed is a highly sensitive photothermographic material containing on a support a silver salt of an organic acid, a photosensitive silver halide, a reducing agent, a binder and, for example, 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.
Claims24
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.
