<p>PURPOSE:To improve finish appearance by using specific resin coating and a specific resin compsn. CONSTITUTION:Coating prepared by compounding a curing agent being a component C with a main agent cpmposed of a copolymer with a hydroxyl number of 20-150 obtained by polymerizing components A, B, C is once applied to the surface of a polyolefinic resin molded article consisting of components E, F, G, H and I without washing the surface of the molded article and applying undercoat primer coating thereto to form a finish coating film. Herein, A is cholinated polyolefin, B is a mixture of an acrylic monomer and an ethylenic monomer, C is a specific polyester prepolymer, D is a polyfunctional isocyanate compd. with an NCO/OH ratio of 0.4-2.0, E is polypropylene, F is a specific ethylene/alpha-olefin copolymer elastomer, G is a modified polyolefin having a polar group represented by formula I (wherein R1 is an alkylene group), H is a compd. represented by formula II or III (wherein R2 is a straight chain alkyl group and X is a compd. represented by formula IV) and I is an inorg. filler.</p> |
