ABSTRACT:
The present invention provides a photothermographic material having, on at least one side of a support, an image forming layer including at least a photosensitive silver halide, a first non-photosensitive organic silver salt, a reducing agent, and a binder, and a non-photosensitive layer including a second non-photosensitive organic silver salt that is different from the first non-photosensitive organic silver salt on the same side of the support as the image forming layer and farther from the support than the image forming layer, wherein the photothermographic material further has a non-photosensitive intermediate layer between the image forming layer and the non-photosensitive layer, and 50% by weight or more of a binder in the non-photosensitive intermediate layer is a polymer latex. A photothermographic material, which exhibits improved image storability and improved resistance to image defects, is provided.
