Abstract
Disclosed is an imaging method which involves exposing to activating radiation in an imagewise manner a film comprised of a matrix polymer as the principal ingredient, a degradable polymer and a photo-oxidant. Exposure of the film causes degradation of the degradable polymer, e.g., poly(acetaldehyde), whereupon the film undergoes a change in optical density in the exposed areas to provide a visible image.
