Abstract:
A abrasion resistant coating composition comprising:(A) 1-50 parts by weight (as solids) of an ultraviolet-curable silicone prepared by chemically modifying 40-90% by weight (as solids) of particulate colloidal silica (a-1) with 10-60% by weight (as solids) of a radical polymerizable silane compound or a hydrolysis product thereof (a-2) represented by the following Formula (I), ##STR4##(where X represents CH.sub.2.dbd.CH--COO--, CH.sub.2 C(CH.sub.3)--COO--, or CH.sub.2.dbd.CH--; R.sup.1 is an alkylene group with 0-8 carbons; R.sup.2 and R.sup.3 are alkyl groups with 1-8 carbons; a is a positive integer of 1-3; b is a positive integer of 0-2; and a+b is a positive integer of 1-3);(B) 45-95 parts by weight of a monomer mixture comprising 30-90 parts by weight of a tris[(meth)acryloyloxy alkyl]isocyanurate(b-1) represented by the following Formula (II), ##STR5##(where X.sup.1, X.sup.2 and X.sup.3 are each either an acryloyl group or a methacryloyl group, R.sup.4, R.sup.5 and R.sup.6 represent an oxyalkylene group or polyoxyalkylene group) and10-70 parts by weight of a urethane poly(meth)acrylate (b-2) having an alicyclic skeleton along with at least two (meth)acryloyloxy groups in the molecule (wherein the total amount of components (b-1) and (b-2) is 100 parts by weight); and(C) 0.01-5 parts by weight of a photo-polymerization initiator (where the total amount of components (A)-(C) is 100 parts by weight).
