ABSTRACT:
A photothermographic element comprising a reflective base having coated thereon one or more layers constituting a photothermographic imaging medium in which a bleachable antihalation medium is coated over said photothermographic imaging medium, the components of the antihalation medium being in non-reactive association with components in the photothermographic imaging medium. The topcoat antihalation layer allows a wide latitude in the selection of dye bleach systems and binders and surprisingly is at least as effective as the use of antihalation underlayers.
