ABSTRACT:
A method of forming a hard coat on a polyolefin base, a composite laminate or a formed article is disclosed, which comprises coating the surface of the polyolefin base with an ultraviolet-curable resin composition comprising (a) a polymer containing at least 80% by weight of methyl methacrylate and/or a modified polymer containing at least 80% by weight of methyl methacrylate and having introduced into the side chain thereof a (meth)acryloyl group, (b) a polyfunctional acrylate containing at least 50% by weight of dipentaerythritol hexaacrylate, the weight ratio of components (a) to (b) being from 1 to 10, and (c) a photopolymerization initiator, drying the coating to form an ultraviolet-curable resin layer, and curing the ultraviolet-curable resin layer by irradiation with ultraviolet light.
