Patent ID: 7229753

Claim:
A photothermographic material comprising: (a) a photosensitive silver halide, (b) a reducible silver salt, (c) a reducing compound represented by the formula (1) below, (d) a binder, and (e) a compound represented by the formula (2) below, wherein the amount of the compound represented by the formula (1) is 0.1–10 mole % of the amount of the compound represented by the formula (2), and an image can be formed by only a single sheet of the photothermographic material without a functional layer constituting a separate member; Q 1 —NHNH—R 1 Formula (1): wherein Q 1 represents a quinazoline ring bonding to NHNH—R 1 at a carbon atom, and R 1 represents a carbamoyl group of the formula —C(═O)—NH—R 11 wherein R 11 is an alkyl group having 1 to 10 carbon atoms or an aryl group having 6 to 10 carbon atoms, wherein V 1 to V 8 each independently represent hydrogen atom or a substituent, and L represents a bridging group consisting of —CH(V 9 )— or —S— where V 9 represents hydrogen atom or a substituent.
