Patent ID: 7157218

Claim:
A photothermographic material comprising: a support having thereon an image forming layer containing a photosensitive silver halide, and a non-photosensitive organic silver salt, both of which have been separately prepared, a reducing agent and a binder, and a non-photosensitive outermost layer on a side of the support where the image forming layer is provided, the photosensitive silver halide which has been separately prepared containing silver iodide in an amount of from 40 to 100% by mole, a binder contained in the non-photosensitive—therein; outermost layer containing at least one of a latex polymer and a water soluble polymer that is not derived from an animal protein in an amount of 50% by mass or more based upon the total binder in the non-photosensitive—therein; outermost layer, and a layer adjacent to the non-photosensitive—therein; outermost layer, which contains a binder of a water soluble polymer that is derived from an animal protein in an amount of 50% by mass or more based upon the total binder in the layer adjacent to the non-photosensitive—therein; outermost layer.
