Abstract

A photothermographic film and a method for making same is taught. The film includes a support, a photothermographic imaging layer coated on the support, and a complement film generally confining the photothermographic imaging layer between the support and the complement film. The complement film is applied to the photothermographic imaging layer prior to exposure of the photothermographic imaging layer. The complement film retains any volatile materials present in the photothermographic imaging layer generated when thermal energy is applied thereto to develop a latent image exposed on the photothermographic imaging layer.
