Photothermographic material

A photothermographic material comprising a support having provided thereon a light-insensitive organic silver salt, a light-sensitive silver halide formed independently of the light-insensitive organic silver salt, and a binder,

• wherein the main binder of an image formation layer containing the light-sensitive silver halide is a synthetic polymer latex having a glass transition temperature of 40.degree. C. or less, said image formation layer is formed by applying a coating solution in which 60% by weight or more of a solvent is water, and the light-sensitive silver halide is silver halide grains having a silver chloride content of 80 mol % or more per silver halide and having localized phases of silver bromide on surfaces thereof.
