  • Silver salt photothermographic dry imaging material
    Patent number: 6709809
    Abstract: A silver salt photothermographic material is disclosed, comprising at least a light sensitive layer and at least a light insensitive layer, the light sensitive layer comprising organic silver salt grains, a light sensitive emulsion containing light sensitive silver halide grains and medium, a reducing agent and a binder, wherein at least one of the light sensitive layer and the light insensitive layer contains a silver-saving agent and the photothermographic material which has been subjected to thermal development at 123° C. for 13.5 sec. exhibits an average contrast of 2.0 to 6.0 within the density range of 0.25 to 2.0 on a characteristic curve of the photothermographic material.
