ABSTRACT:
A photothermographic material including, on at least one side of a support, an image forming layer including at least a photosensitive silver halide, a non-photosensitive organic silver salt, a reducing agent, and a binder, and a non-photosensitive layer, wherein the photothermographic material contains a metal phthalocyanine dye represented by formula (I):wherein, M represents a metal atom; R1, R2, R3, R4, R5, R6, R7, and R8each independently represent a hydrogen atom or a substituent, with at least one of them being a substituent; X1, X2, X3, and X4each independently represent a hydrogen atom or a substituent; and at least one of R1, R2, R3, R4, R5, R6, R7, R8, X1, X2, X3, and X4is an oil-soluble group. The invention provides a photothermographic material which exhibits preferable image tone and excellent image storability.
