<p><P>PROBLEM TO BE SOLVED: To provide an active energy ray-curable composition which can form cured films having sufficiently excellent weather resistance and abrasion resistance. <P>SOLUTION: The active energy ray-curable composition comprises an active energy ray-curable prepolymer (A) capable of being obtained by the reaction of a hydroxyl group-having acrylic prepolymer with an isocyanate group-having acrylic monomer (a4), an active energy ray-curable compound (B) having a benzotriazole group, one or more other active energy ray-curable compounds (C) different from the components (A) and (B), and inorganic oxide particles (D), wherein the hydroxyl group-having acrylic prepolymer is a copolymer containing a piperidinyl group-having acrylic monomer (a1), a hydroxyl group-having acrylic monomer (a2), and one or more other monomers (a3) as monomer units. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
