Abstract
A photothermographic material for a photomechanical process which is high in sensitivity and high in contrast and can provide an image low in Dmin by UV light, 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 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 gold-sensitized silver halide grains having a silver chloride content of 80 mol % or more per silver halide.
