More Information
Summary:A coating composition comprising: (a) a cross-linking polymerizable compound (a-1) having at least two (meth)acryloyloxy groups in its molecule or a mixture of the compound (a-1) and a compound (a-2) copolymerizable therewith ; (b) fine silica particles with their surfaces modified with a hydrolyzate of a mixture of a silane compound (b-1) capable of binding with the component (a) and another silane compound (b-2) incapable of binding with the component (a ); and (c) an initiator for actinic radiation-induced polymerization. The composition can give a cured coating having a high surface strength and an excellent weathering resistance, and is applicable without using any solvent .
