Abstract
A photothermographic material having, 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 at least one non-photosensitive layer, wherein the photothermographic material contains a water-insoluble azomethine dye and a metal phthalocyanine dye represented by formula (PC-1): wherein M represents a metal atom; R1, R2, R3, R4, R5, R6, R7, and R8 each independently represent a hydrogen atom or a substituent; and at least one of them is an electron-attracting group. The invention provides a photothermographic material which exhibits preferable image tone and excellent image storability.
