Excellent and durable demisting property can be imparted to the surface of the transparent materials such as glass and plastics by coating onto the surface of said transparent materials a copolymer obtained by subjecting 2-hydroxyethyl methacrylate to solution polymerization and then graft-copolymerizing an allyl alcohol tribasic acid ester thereonto and then curing the copolymer by heating it. In this case, if an organo silicon nonionic surface active agent is added to said copolymer, more effective demisting property can be imparted to the surface of the transparent materials.
