ABSTRACT:
A thermally processable imaging element is disclosed having a protective coat overlying at least one thermographic or photothermographic imaging layer containing an organic silver salt and a thermally activated reducing agent for silver ion. The protective coat includes a film-forming binder comprised of a water dispersible polymer containing hydroxy pendant groups and, to reduce low density spots visible after thermal processing, a combination of anionic, non-ionic and fluorocarbon moiety containing surfactants satisfying formula defined selection criteria.
