ABSTRACT:
Positive-acting photothermographic elements suitable for use in graphic arts and medical imaging comprising a photosensitive medium comprising a reducible silver source, a photo-acid generator, a binder and a reducing system for silver ion comprising a reducing agent for silver ion in which exposure of the element to actinic radiation causes the production of acidic species in the exposed regions which inhibit reduction of the silver source by the reducing system.
