    摘要: Disclosed is an active energy ray-curable coating composition containing (A) 10 to 70% by mass of a poly(meth)acrylate of a mono- or polypentaerythritol; (B) 5 to 50% by mass of (B-1) a polyester type aliphatic urethanedi(meth)acrylate compound which is obtained by reacting an aliphatic isocyanate compound, a caprolactone-modified polyester diol, and an acrylate having a hydroxyl group, (B-2) a compound represented by formula (2), or (B-3) a polyether type urethane di(meth)acrylate compound having two (meth)acryloyloxy groups in a molecule, wherein, in the case that component (B) is component (B-3), component (A) contains at least one caprolactone-modified (meth)acryloyloxy group; (C) 5 to 70% by mass of a poly[(meth)acryloyloxyalkyl](iso)cyanurate represented by formula (3) or (4); and (D) 0.1 to 10% by mass of a photopolymerization initiator. The active energy ray-curable coating composition can form a cured film excellent in weatherability, mar resistance, and adhesion to a base material.
