Abstract
PURPOSE: To improve the durability of forms, and to increase the number of repeated rotation by laminating a plywood surface and a resin film surface with ultraviolet curing adhesives and curing the adhesives by applying ultraviolet rays from the upper section of a resin film. CONSTITUTION: Ultraviolet curing adhesives comprising an approximately 40-80 pts.wt. photosensitive resin prepolymer having one or more of reactive functional groups and molecular weight of approximately 500-10000, an approximately 10-50 pts.wt. crosslinking agent and an approximately 0.5-10 pts.wt. sensitizer is constituted. Either one or both of a transparent resin film surface having thickness of approximately 5-200 μm, preferably 10-100 μm or a plywood surface are coated with ultraviolet curing adhesives, plywood and a resin film are laminated, and the adhesives are cured by applying ultraviolet rays from the upper section of the resin film, and the resin film is stuck onto plywood.
