<P>PROBLEM TO BE SOLVED: To provide an active energy ray-curable composition obtainable of a cured coating film, whose hardness, even though obtained by active energy ray irradiation under oxygen atmosphere, is equivalent to the hardness obtained by active energy ray irradiation under nitrogen atmosphere, and which has excellent scratch resistance. <P>SOLUTION: The active energy ray-curable composition includes: a silsesquioxane compound (A) having organic groups directly bonded to a silicon atom, wherein at least one of the organic groups directly bonded to a silicon atom are organic groups having at least one selected from the group consisting of a secondary hydroxy group, a urethane bond, and a urea bond, and at least one (meth)acryloyloxy group simultaneously; and isosorbide di(meth)acrylate (B). <P>COPYRIGHT: (C)2013,JPO&INPIT |
