PURPOSE:To provide a laminated material in which the adhesion between the PVC layer of poor adhesion and the ultraviolet-curing resin is improved by forming an ultraviolet-curing resin coating layer prepared by polymerizing a specified monomer on the surface of a film containing such a specified monomer and polymerizing the monomer contained in the film. CONSTITUTION:A laminated material prepared by forming an ultraviolet-curing resin coating layer obtained by polymerizing an ethylenically unsaturated monomer and/or its oligomer on the surface of a film containing polyvinyl chloride, a plasticizer and an ethylenically unsaturated monomer and/or its oligomer, and polymerizing the monomer and/or the oligomer contained in the film. Examples of the curable monomers used include acrylic esters having one to several functional groups in the molecule and methacrylic acid. As the oligomers, photopolymerizable oligomers such as epoxy acrylate and urethane acrylate usually used for ultraviolet-curable coating materials are desirable. |
