ABSTRACT:
A photothermographic element containing a transparent substrate having one major surface thereof containing the following layers sequentially coated thereon: an image-receiving layer; an opacifying layer; a first dry silver layer; an interlayer containing thermoplastic polymer; a second dry silver layer; an interlayer containing thermoplastic polymer; and a third dry silver layer, wherein the first, second, and third dry silver layers each contain a light-insensitive, reducible silver source; light-sensitive silver halide, and as a reducing agent for the light-insensitive, reducible silver source, a material oxidizable to a colored dye whose color differs from that capable of being formed in each other dry silver layer, each of the dry silver layers being individually sensitized to light of different wavelengths.
