Abstract
A thermally-activatable overcoat-releasing laminate useful for the application of a protective overcoat onto a planar surface, such as a binary image surface on a peel-developed laminar imaging medium, is provided. The overcoat-releasing laminate comprises a durable layer and an adhesive layer firmly interconnected at an interface, the firm interconnection being resultant of polymerization of a photopolymerizable monomer by exposure to ultraviolet radiation. As effected by the firm interconnection, use of the overcoat-releasing laminate is characterized by reliable release of the protective overcoat from a carrier web.
