Abstract
Various photothermographic elements are provided containing a transparent substrate; image receiving layers; dry silver layers; interlayers; and a translucent or opacifying layer. The translucent or opacifying layer can occupy a variety of positions in the photothermographic element relative to the dry silver layers. The translucent or opacifying layers serve to help produce a reflection print upon exposure of the photothermographic element to actinic light and subsequent heating of the exposed element for image development and dye transfer.
