Coating compsn. can be directly applied to a polyolefin moulded prod. comprising chlorinated polyolefin, an active hydride for urethane resin and a setting agent, major component being diisocyanate. In an example, a coating compsn. was prepd. by mixing chlorinated polypropylene resin (100 pts.wt.), polyester polyol (60 wt. portions), titanium oxide (50 pts.wt.), toluene (50 pts.wt.) and setting agent (100 ). The compsn. was directly applied to the polypropylene moulded prod. made for parts of motorcycle after degreasing the surface with benzene.
