| abstract |
A coating composition comprising (a) a crosslinking polymerizable compound (a-1) having at least two (meth)acryloyloxy groups in the molecule, or a mixture of this compound (a-1) and a compound (a-2) copolymerizable therewith, (b) finely divided silica having its surfaces modified by a hydrolyzate of a mixture composed of a silane compound (b-1) capable of forming a bond with component (a), and a silane compound (b-2) incapable of forming a bond with component (a), and (c) a high-energy radiation polymerization initiator. This coating composition can form a cured film having high surface hardness and excellent weather resistance, and can be applied in solventless form. |
