Abstract
In an uncured filled coating composition comprising (a) a polyfuntional acrylic-type carboxylic acid ester monomer or its prepolymer, (b) a polymerization initiator capable of curing said monomer or prepolymer (a), and (c) an inorganic solid filler; the improvement wherein said composition consists essentially of PA1 (A) 100 parts by weight of said polyfunctional acrylic-acid carboxylic acid ester monomer or its prepolymer (a), said polyfunctional monomer or prepolymer (a) being composed of 0 to 75% by weight of a trifunctional or higher acrylic-type carboxylic acid ester monomer or its prepolymer having a molecular weight of about 200 to about 700 and 25 to 100% by weight of a difunctional acrylic-type carboxylic acid ester monomer or its prepolymer having a molecular weight of about 160 to about 400, PA1 (B) 0.001 to 20 parts by weight of said polymerization initiator (b) capable of curing said monomer or prepolymer (A), and PA1 (C) 5 to 250 parts by weight of said inorganic solid filler (c), said filler (c) having a refractive index of 1.40 to 1.60 and an average first-order particle diameter of at least 1 m.mu. but less than 1.mu.; and a cured filled coating composition prepare…
