<p><P>PROBLEM TO BE SOLVED: To provide an active energy ray-curable composition including an organic/inorganic composite microparticle and formable of a coating film excellent in solvent resistance, adhesiveness, scratch resistance and chemical resistance. <P>SOLUTION: This active energy ray-curable composition includes a radically polymerizable unsaturated group-containing compound (A), an organic/inorganic composite microparticle (B) and a photopolymerization initiator (C), where the organic/inorganic composite microparticle (B) is obtained by reacting a living polymer (b<SB POS="POST">1</SB>), inorganic microparticles (b<SB POS="POST">2</SB>) having a polymerizable unsaturated group, etc., in the presence of a solvent and, if necessary, vaporizing the solvent; and the living polymer (b<SB POS="POST">1</SB>) is obtained by living-radical polymerization of an unsaturated monomer (b<SB POS="POST">12</SB>) added with an aminoether compound (b<SB POS="POST">11</SB>), or a nitroxide compound and a radical polymerization initiator, as the initiator of living radical polymerization. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
