<P>PROBLEM TO BE SOLVED: To provide an active energy ray-curable coating material composition excellent in curability that affords a molded product having a surface of a cured film excellent in smoothness and being excellent in adherability of the cured film to a metal substrate as well as moisture resistance, and to provide a molded product having the cured film laminated thereon. <P>SOLUTION: The active energy ray-curable coating material composition comprises: 30-60 pts.mass of a copolymer (A) containing a dibutyl fumarate unit and a hydroxy group-containing monomer unit and having a mass-average molecular weight of 20,000-40,000 and a hydroxy value of 40-60 mgKOH/g; 25-69.9 pts.mass of (meth)acrylate (B) having at least one (meth)acryloyloxy group in the molecule; and 0.1-15 pts.mass of a photoinitiator (C), wherein the total amount of the copolymer (A), the (meth)acrylate (B) and the photoinitiator (C) is 100 pts.mass. The molded product is obtained from the composition. <P>COPYRIGHT: (C)2012,JPO&INPIT |
