A trim strip is produced by extrusion coating a metallic insert with a vinyl chloride resin material through the medium of an acrylic resin type adhesive agent. The vinyl chloride resin material has the resin component thereof formed of 100 parts by weight of straight resin having an average polymerization degree, &upbar& P, in the range of 1,000 to 3,000 and 15 to 50 parts by weight of polymethyl methacrylate having an average molecular weight, &upbar& M, in the range of 1,000,000 to 4,000,000. The trim strip, therefore, produces high adhesive strength between the metallic insert and the vinyl chloride resin layer, enjoys satisfactory extrusibility, and entails substantially no formation of fisheyes in the coating of the produced trim strip. |
