ABSTRACT:
An imageable composite dry-transfer sheet that comprises (a) a cover sheet transmissive to actinic radiation that has at least one oleophilic surface, (b) a photopolymerizable layer on the oleophilic surface of the cover sheet that comprises a cationically polymerizable organic material, a cationic photopolymerization initiator, and, optionally, a thermoplastic hydrocarbon resin that is chemically inert to said organic material and said initiator and (c) a base sheet with an oleophobic surface on the photopolymerizable layer wherein, after image-wise exposure to activating radiation, the interfacial adhesion of the unexposed areas of the photopolymerizable layer is greater for the cover sheet than for the base sheet; the interfacial adhesion of the exposed areas of the photopolymerizable layer is greater for the base sheet than for the cover sheet; and wherein, after separation of the cover and base sheets, the unexposed areas of the photopolymerizable layer are rendered burnishable by subsequent exposure to activating radiation through the cover sheet.
