Abstract
A silver salt photothermographic dry imaging material comprising a support having thereon a photosensitive layer comprising silver aliphatic carboxylate grains and photosensitive silver halide grains, a reducing agent for silver ions, a binder and a cross-linking agent, wherein the photothermographic material has a silver coverage of 1.0 to 1.7 g/m2; the photosensitive silver halide grains have a mean grain size of 0.03 to 0.055 μm and a degree of grain size dispersity of not more than 30%; after the dry imaging material has been subjected to photothermographic processing at a temperature of 100 to 200° C. for 5 to 50 seconds, the photosensitive layer exhibits a thermal transition temperature of 46 to 200° C.
