Patent ID: 7153646

Claim:
A photothermographic material comprising, on at least one side of a support, an image forming layer comprising at least a photosensitive silver halide, a non-photosensitive organic silver salt, a reducing agent, and a binder, and a non-photosensitive layer which is disposed on the same side of the support as the image forming layer and farther from the support than the image forming layer, wherein 1) the photothermographic material further comprises a non-photosensitive intermediate layer between the image forming layer and the non-photosensitive layer, and 50% by weight or more of a binder of the non-photosensitive intermediate layer is formed by a polymer latex; and 2) the photothermographic material contains a metal phthalocyanine dye represented by formula (PC-1): wherein, M represents a metal atom; R 1 , R 4 , R 5 , R 8 , R 9 , R 12 , R 13 , and R 16 each independently represent a hydrogen atom or a substituent; at least one of R 1 , R 4 , R 5 , R 8 , R 9 , R 12 , R 13 , and R 16 is an electron-attracting group; and R 2 , R 3 , R 6 , R 7 , R 10 , R 11 , R 14 , and R 15 each independently represent a hydrogen atom or a substituent.
