The present invention relates to urethane acrylate (A) having an unsaturated group equivalent of 100 to 900 and a weight average molecular weight of 500 to 2500, and 65 to 90% by mass of methyl methacrylate (a) based on the total amount of copolymerization components, and hydroxyl group-containing polymerizability. Hydroxyl group-containing acrylic resin (B), polyisocyanate compound (C) and photopolymerization containing 10 to 35% by weight of unsaturated monomer (b) and 0 to 25% by weight of other polymerizable unsaturated monomer (c) as copolymerization components A coating composition containing an initiator (E) is provided. |
