    Abstract: The present invention relates to a UV curable resin composition for coating, and especially relates to a UV curable resin composition useful for coating the surface of a polycarbonate resin molded article such as a lump cover for automobiles. In the UV curable resin composition for coating of the present invention, to 100 parts by weight of the film forming components (a) 10 - 70 wt. % of a mono- or bi- functional monomer having a molecular weight of 130 - 700, and having ether bond and one or two acryloyloxy groups per molecule, (b) 5 - 60 wt. % of an aliphatic urethane acrylate oligomer, (c) 10 - 30 wt. % of a methyl methacrylate polymer having a molecular weight of 10000 to 200000, and as necessary, and (d) 5 - 50 wt. % of a polyfunctional monomer having a molecular weight of 250 - 700 and having three or more acryloyloxy groups per molecule, there are mixed 2 - 10 parts by weight of a photopolymerization initiator, and 2 - 20 parts by weight of a UV absorber. By using the UV curable resin composition for coating of the present invention, it is possible to obtain a coating film having excellent crack resistance, adhesiveness and scarring resistance, even when used outdoors for long periods of time.
