The present invention provides a photothermographic material having, on one side of a support, an image forming layer including at least a photosensitive silver halide, a non-photosensitive organic silver salt, a reducing agent for the organic silver salt, and a binder, and at least one non-photosensitive layer and, on the other side of the support, a non-photosensitive back layer, wherein a total amount of ammonia contained in the two sides is from 5×10−4 mol/m2 to 2×10−2 mol/m2, and a molar ratio (A2/A1) of an ammonia content of the non-photosensitive back layer (A2) to an ammonia content of the layer on the image forming layer side (A1) is from 0.3 to 5.0; or a photothermographic material according to the above, wherein the non-photosensitive back layer includes an ammonium salt, and an ammonia content of the non-photosensitive back layer is from 2 mg/m2 to 100 mg/m2.
A photothermographic material comprising, on one side of a support, an image forming layer comprising at least a photosensitive silver halide, a non-photosensitive organic silver salt, a reducing agent for the organic silver salt, and a binder, and at least one non-photosensitive layer and, on the other side of the support, a non-photosensitive back layer, wherein both of at least one layer on the side having the image forming layer and the non-photosensitive back layer comprise an ammonium salt of an organic acid, a total amount of ammonia contained in the two sides is from 5×10−4 mol/m2 to 2×10−2 mol/m2, and a molar ratio (A2/A1) of an ammonia content of the non-photosensitive back layer (A2) relative to an ammonia content of the at least one layer on the side having the image forming layer (A1) is from 0.3 to 5.0.
A photothermographic material comprising, on one side of a support, an image forming layer comprising at least a photosensitive silver halide, a non-photosensitive organic silver salt, a reducing agent for the organic silver salt, and a binder, and a non-photosensitive back layer on the other side of the support, wherein the non-photosensitive back layer comprises an ammonium salt of an organic acid, and an ammonia content of the non-photosensitive back layer is from 2 mg/m2 to 100 mg/m2.
