Zusammenfassung:	PURPOSE:To obtain the titled copolymer useful as an anti-fogging agent for glass, etc., having adhesivity to glass, and high moisture absorption strength, by copolymerizing an hydroxyl group-containing acrylic ester, etc. with a sulfonic group-containing acrylic ester, and a Si-containing acrylic ester. CONSTITUTION:(A) An acrylic monomer shown by the formula I [R is H, or methyl; X is group shown by the formula -OR OH (R is alkylene), or group shown by the formula NHC(CH3)2CH2COCH3] is copolymerized with (B) a sulfoalkyl (meth)acrylate shown by the formula II (M is alkali metal; n is 2, or 3) and (C) a trialkoxysilylalkyl (meth)acrylate shown by formula III (R is 1-2C alkyl) in a weight ratio of 1
