(57) [Abstract] [Purpose] To obtain a coating material composition having a high surface hardness, capable of forming a cured coating having excellent weather resistance, and capable of being coated without solvent. [Structure] (a) Crosslinkable polymerizable compound (a-) having at least two (meth) acryloyloxy groups in the molecule. 1), or a mixture of the compound (a-1) and a copolymerizable compound thereof, (b) cannot form a bond with the silane compound (b-1) and the component (a) which can form a bond with the component (a). A coating material composition containing silica fine particles whose surface is modified with a hydrolyzate of a mixture with a silane compound (b-2), and (c) an active energy ray polymerization initiator. |
