ABSTRACT:
An imaging medium comprises a layer, depolymerizable by exposure to actinic radiation and substantially non-tacky prior to depolymerization but becoming tacky upon at least partial depolymerization, disposed adjacent a layer of an imaging material, which has a cohesive strength greater than the adhesive strength between the imaging material and the depolymerizable layer prior to 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 tacky and firmly attaching exposed areas of the imaging material layer to the depolymerizable layer. The unexposed areas of the imaging material are then removed from the depolymerizable layer.
