Abstract
A method for modifying the surface of a polyolefin resin molded article is disclosed, comprising contacting a polyolefin resin molded article with an ozone aqueous solution to oxidize the surface of said molded article. The surface of a polyolefin resin molded article can be modified easily and uniformly whatever shape the molded article may have. Previous cleaning of the molded article with an organic solvent is unnecessary. A coating layer can be formed on the thus modified surface with high adhesion.
