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.
Claims12
A black-and-white silver image-forming 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 magnesium and/or calcium element 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, an optically functional back layer containing at least one dye that can be discolored by thermal development processing, wherein at least one of the optically functional back 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.
