Abstract:
A coating composition, comprising 50 to 99 parts by weight of a monomer or monomer mixture (M) composed of 50 to 100% by weight of a polyfunctional (meth)acrylate monomer (m-1) having at least two (meth)acryloyloxy groups in the molecule and 0 to 50% by weight of a monofunctional (meth)acrylate monomer (m-2) copolymerizable with the monomer (m-1), and 1 to 50 parts by weight of colloidal silica which is acryl-functionalized colloidal silica having a surface modified with a hydrolysate of a silane compound copolymerizable with a monomer or monomer mixture (M), wherein the colloidal silica contains colloidal silica in a narrow and long form having an average diameter of 5 to 20 nm and an average length of 40 to 300 nm in an amount of 5 to 100% by weight based on the total colloidal silica weight.
