Abstract
An imaging medium comprises a layer, depolymerizable by exposure to actinic radiation and undergoing a reduction in cohesivity upon at least partial depolymerization, disposed adjacent a layer of an imaging material, which has a cohesive strength greater than the cohesive strength of the depolymerizable layer after depolymerization. This medium is imagewise exposed to radiation, thereby causing at least partial depolymerization of the polymer in the exposed areas, so rendering these exposed areas lower in cohesivity than the unexposed areas. The exposed areas of the imaging material are then removed from the depolymerizable layer.
