Claims
- 1. A coated molded article comprising:
- (a) a body of a molded article comprising a plasticizing olefin resin; and
- (b) a finish coat consisting essentially of an acrylic urethane resin paint formed from a composition consisting essentially of:
- (i) graft copolymer comprising a polar group-introduced polyolefin as a main backbone chain and a plasticizing acrylic polyol resin as a side chain;
- (ii) a plasticizing acrylic polyol resin;
- (iii) a plasticizing polyester-containing polymer; and
- (iv) hexamethylene diisocyanate, the finish coat being formed directly on the body of the molded article.
- 2. A coated molded article according to claim 1, wherein the ratio of the graft copolymer to the plasticizing acrylic polyol resin to the plasticizing polyester-containing polymer is in a range of 4:3:3 to 8:1:1.
- 3. A coated molded article according to claim 1, wherein the polar group-introduced polyolefin is a chlorinated polypropylene.
- 4. A coated molded article according to claim 3, wherein the ratio of the plasticizing acrylic polyol resin to chlorinated polypropylene is in a range of 60:40 to 95:5.
- 5. A coated molded article according to claim 1, wherein the plasticizing olefin resin is a styrene-containing thermoplastic elastomer.
- 6. A coated molded article comprising:
- (a) a body of a molded article comprising a rigid olefin resin having a Rockwell hardness of 100 or more in R scale;
- (b) a primer coat consisting essentially of a modified polyolefin resin consisting essentially of:
- (i) a graft-copolymer comprising a polar group-introduced polyolefin as a main backbone chain and an acrylic polyol resin as a side chain; and
- (ii) a polar group-introduced polyolefin;
- (c) a finish coat consisting essentially of a rigid acrylic urethane resin paint formed from a composition consisting essentially of:
- (i) a modified acrylic polyol resin comprising an acrylic polyol resin and a polar group-introduced polyolefin;
- (ii) an acrylic polyol resin; and
- (iii) hexamethylene diisocyanate, the primer coat being interposed between the body of the molded article and the finish coat.
- 7. A coated molded article according to claim 6, wherein the ratio of the graft copolymer in the primer coat to the polar group-introduced polyolefin in the primer coat is in a range of 4:6 to 8:2.
- 8. A coated molded article according to claim 6, wherein the ratio of the modified acrylic polyol resin in the finish coat to the acrylic polyol resin in the finish coat is in a range of 5:5 to 8:2.
- 9. A coated molded article according to claim 6, wherein the polar group-introduced polyolefin in the primer coat is a chlorinated polypropylene, and wherein the ratio of the graft copolymer in the primer coat to the chlorinated polypropylene in the primer coat is in a range of 7:3 to 9:1.
- 10. A coated molded article according to claim 6, wherein the rigid olefin resin has been reinforced with a glass fiber and the primer coat contains a silane coupling agent.
- 11. A coated molded article according to claim 6, wherein at least one of the polar group-introduced polyolefin in the primer coat and the polar group-introduced polyolefin in the finish coat is a chlorinated polypropylene.
