Patent ID: 7108965

Claim:
A photothermographic material comprising a support, and an image forming layer provided on at least one side of the support, the image forming layer comprising at least a photosensitive silver halide, a non-photosensitive organic silver salt, a reducing agent and a binder, wherein: (1) a silver iodide content of the photosensitive silver halide is not less than 40 mole %; (2) the binder comprises a hydrophilic binder; (3) the image forming layer comprises a silver iodide complexing agent; and (4) the image forming layer comprises, as a silver carrier, at least one compound represented by the following Formula (I) or (II): (wherein Q represents an atomic group that is necessary to form a 5 or 6-membered imide ring); (wherein: R 5 independently represents a hydrogen atom, alkyl group, cycloalkyl group, alkoxy group, alkylthio group, arylthio group, hydroxyl group, halogen atom or N(R 8 R 9 ), where R 8 and R 9 each independently represents a hydrogen atom, alkyl group, aryl group, cycloalkyl group, alkenyl group or heterocyclic group; r represents 0, 1 or 2; R 8 and R 9 may be bonded to each other to form a substituted or unsubstituted 5 to 7-membered hetero ring; two groups represented by R 5 may be linked together to form an aromatic, heteroaromatic, alicyclic or heterocyclic condensed ring; and X represents O, S, Se or N(R 6 ), where R 6 represents a hydrogen atom, alkyl group, aryl group, cycloalkyl group, alkenyl group or heterocyclic group).
