Method of coating a polyolefin molded part, which method comprises coating onto the polyolefin molded part without any pretreatment or with a pretreatment by washing with an aqueous medium an undercoating containing, as a major component, a composition consisting of 100 parts by weight of (A) an unsaturated dicarboxylic acid-modified chlorinated polypropylene having an acid value of 3 to 80, a degree if chlorination in the range of 18 to 28% by weight as a chlorine content and a weight-average molecular weight of 30,000 to 170,000, 1 to 50 parts by weight of (B) an epoxy resin having a weight-average molecular weight of 250 to 2,000 and an epoxy equivalent of 90 to 1,200, and preferably 2 parts by weight or less of (C) a catalyst, followed by coating a topcoating. |
