US Patent 7223531 Photothermographic material

The invention provides a photothermographic material containing, on a support, an image forming layer having at least a photosensitive silver halide, a non-photosensitive organic silver salt and a reducing agent, and at least one non-photosensitive layer, in which the non-photosensitive layer contains a crosslinking agent precursor, in which the crosslinking agent precursor is a compound which releases a crosslinking agent which crosslinks a binder of the non-photosensitive layer at the time of thermal development. A photothermographic material in which water resistance and scratch resistance of an image have been improved is provided.
