A photothermographic imaging material containing a support having thereon: (i) a photosensitive layer containing photosensitive silver halide grains, light-insensitive organic silver salt grains, a binder, and a reducing agent for silver ions; and (ii) one or more non-photosensitive layers, wherein a powder compound which is preliminarily dried at a lower temperature than a temperature used for thermal development is incorporated in the photosensitive layer or in the non-photosensitive layer.

Silver salt photothermographic dry imaging material

A photothermographic imaging material comprising a support having thereon, (a) a photosensitive layer containing an organic silver salt, photosensitive silver halide grains, a reducing agent and a binder, (b) a light-insensitive layer, and (c) a protective layer, wherein a weight reducing value from 25&#xb0; C. to 100&#xb0; C. by a heat drying weight measurement of the photographic imaging material is not more than 0.4% based on a weight value at 25&#xb0; C.
