Abstract
The present invention provides a photothermographic material having, on at least one side of a support, an image forming layer including at least a photosensitive silver halide, a first non-photosensitive organic silver salt, a reducing agent, and a binder, and a non-photosensitive layer including a second non-photosensitive organic silver salt which is different from the first non-photosensitive organic silver salt, wherein particles of the second non-photosensitive organic silver salt have a mean equivalent circular diameter of from 0.03 μm to 0.5 μm. A photothermographic material, which exhibits improved color tone of developed silver images, improved resistance to damage from fingerprints, and high resistance to image defects, is provided.

A photothermographic material comprising, on at least one side of a support, an image forming layer comprising at least a photosensitive silver halide, a first non-photosensitive organic silver salt, a reducing agent, and a binder, and a non-photosensitive layer comprising a second non-photosensitive organic silver salt which is different from the first non-photosensitive organic silver salt, wherein the first non-photosensitive organic silver salt is a silver salt of a fatty acid, and the second non-photosensitive organic silver salt is a silver salt of a nitrogen-containing heterocyclic compound having a mean equivalent circular diameter of from 0.03 μm to 0.5 μm, and a ratio of an amount of the second non-photosensitive organic silver salt relative to an amount of the first non-photosensitive organic silver salt is from 0.5 mol % to 50 mol % on the basis of silver molar ratio.
