Abstract
A photothermographic material including, on one side of a support, an image forming layer containing at least a photosensitive silver halide, a non-photosensitive organic silver salt, a reducing agent and a binder, and, on the other side of the support, a non-photosensitive back side layer. The total quantity of an alkaline earth metal contained in the non-photosensitive back side layer is 1×10−5 mol/m2 to 1×10−3 mol/m2.

A photothermographic material comprising, on one side of a support, an image forming layer containing at least a photosensitive silver halide, a non-photosensitive organic silver salt, a reducing agent and a binder, and, on the other side of the support, a non-photosensitive back side layer, wherein the non-photosensitive back side layer contains at least gelatin as a binder, and a total quantity of one or more water-soluble alkaline earth metals contained in the non-photosensitive back side layer is 1×10−5 mol/m2 to 1×10−3 mol/m2.
A photothermographic material comprising, on at least one side of a support, an optically functional layer containing at least one dye that can be discolored by thermal development processing, wherein the optically functional layer is a back layer, at least one of the optically functional layer and a layer adjacent thereto contains at least one polymer having a glass transition temperature of −10° C. to 120° C., the at least one polymer having a glass transition temperature of −10° C. to 120° C. is a latex of a styrene-butadiene copolymer, and the polymer in the back layer is in a range of 10% to 50% by mass based on gelatin in the back layer.
