Claims
- 1. A coated plastic molding comprising:
a molding body being molded with polyolefin plastic material, and having an elastic modulus in tension in a range of from 230 to about 2,000 MPa; and a final coating comprising acryl-urethane paint provided on said molding body, wherein a ratio E′/E is not smaller than 0.5, wherein E represents the elastic modulus in tension of said molding body according to ASTM D 638, and E′ represents elastic modulus in tension of said final coating according to JIS K 7244-4, and wherein said final coating resists a minimum of 30 reciprocal scratches applied by an abrading apparatus in substantially the same location under defined loading and velocity conditions before peeling.
- 2. A coated plastic molding according to claim 1, wherein said ratio E′/E is not larger than 5.
- 3. A coated plastic molding according to claim 1, wherein said acryl-urethane paint comprises a polyol component and a polyisocyanate component.
- 4. A coated plastic molding according to claim 3, wherein said polyol component comprises:
acryl graft chlorinated PO; polymeric acryl polyol having a glass transition point not lower than 5° C.; and polymeric polyester polyol having a glass transition point not higher than 10° C.
- 5. A coated plastic molding according to claim 3, wherein said polyisocyanate component comprises aliphatic polyisocyanate.
- 6. A coated plastic molding according to claim 3, wherein said polyisocyanate component comprises cycloaliphatic polyisocyanate.
- 7. A coated plastic molding according to claim 3, wherein said polyisocyanate component comprises aromatic polyisocyanate.
- 8. A coated plastic molding according to claim 1, wherein the ratio E′/E is not smaller than 0.6 and not larger than 2.5.
- 9. A coated plastic molding according to claim 1, wherein the defined loading and velocity conditions comprise a load of 500 g applied by the abrading apparatus at a velocity of 50 reciprocations per minute.
- 10. A coated plastic molding, comprising:
a molding body being molded with polyolefin plastic material, and having an elastic modulus in tension in a range of from 230 to about 2,000 MPa; and a final coating comprising acryl-urethane paint provided on said molding body, wherein a ratio E′/E is not smaller than 0.5, wherein E represents the elastic modulus in tension of said molding body, and E′ represents elastic modulus in tension of said final coating, and wherein said final coating resists a minimum of 30 reciprocal scratches applied by an abrading apparatus in substantially the same location under defined loading and velocity conditions before peeling.
