摘要： A photothermographic material having, on at least 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 at least one non-photosensitive layer which is disposed on the same side as the image forming layer and farther from the support than the image forming layer, wherein (1) 50% by weight or more of the binder is a polymer latex having a monomer component having an acid group, and (2) the polymer latex has a core/shell structure having a core part and a shell part, and the monomer component having an acid group in the core part is 2 mol% to 20 mol% of a total amount of the monomer component having an acid group in the polymer latex. The invention provides a photothermographic material which exhibits excellent image uniformity with low fog.
