ABSTRACT:
In a photothermographic element comprising a photosensitive layer containing an organic silver salt, a silver halide, and a reducing agent on one surface of a support, and a back layer on the other surface of the support, the outermost back layer is based on a polymer latex binder, and the back layer contains a dye of formula (I) satisfying a specific maximum absorption wavelength relationship. The element produces an image with high Dmax, ultrahigh contrast, satisfactory resolution, and minimized residual color.
