Abstract:
1. A photothermographic material comprising at least an image-forming layer on at least one surface of a support, the iamge-forming layer containing a photosensitive silver halide, a non-photosensitive organic silver salt, a reducing agent, and a binder, further comprising: an outermost layer containing a binder as a layer furthest from the support on the side of the support where the image-forming layer is provided; a non-photosensitive intermediate layer A containing a binder and provided adjacent to the image-forming layer and between the image-forming layer and the outermost layer, wherein the binder of the non-photosensitive intermediate layer A contains 80% by mass or more of a polymer formed by copolymerizing a monomer represented by following Formula (M), a non-photosensitive intermediate layer B containing a binder and provided between the non-photosensitive intermediate layer A and the outermost layer, and at least one binder of the binder of the outermost layer and the binder of the non-photosensitive intermediate layer B contains 50% by mass or more of a hydrophilic polymer derived from animal protein: wherein R 01 and R 02 represent each independently a hydrogen atom, an alkyl group of from 1 to 6 carbon atoms, a halogen atom or a cyano group.
