Abstract:
1. A molded composite article in which a resin member comprising a non-urethane thermoplastic resin and a resin member comprising a thermoplastic polyurethane resin are directly bonded with each other, wherein the non-urethane thermoplastic resin is a non-urethane thermoplastic resin (Ib) which is (Ib-1) a polyamide resin comprising a polyamide component having an alicyclic ring and contains a terminal amino group in a concentration of not less than 15 mmol/kg, wherein a part of or all the terminal amino group is an alicyclic amino group, or (Ib-2) a resin composition comprising a non-urethane thermoplastic resin and an amino group-containing compound, the non-urethane thermoplastic resin (Ib) has an amino group in a concentration of not less than 15 mmol/kg, in the polyamide resin (Ib-1), the polyamide component having an alicyclic ring is at least one member selected from the group consisting of an alicyclic polyamide resin, an alicyclic polyamide elastomer, and a polyamide component having an alicyclic ring comprising an alicyclic polyamide component and a non-alicyclic polyamide component, wherein said alicyclic polyamide component is at least one member selected from the group consisting of an alicyclic polyamide resin, an alicyclic polyamide elastomer and an alicyclic polyamide oligomer; and said non-alicyclic polyamide component is at least one member selected from the group consisting of an aliphatic polyamide resin and an aromatic polyamide resin, in the resin composition (Ib-2), the non-urethane thermoplastic resin comprises at least one member selected from the group consisting of a polyamide resin, a polyester resin, a polycarbonate resin, and a polyphenylene sulfide resin, the amino group-containing compound is a polyamide oligomer having a number average molecular weight of 2000 to 9000, and the thermoplastic polyurethane resin is a thermoplastic polyurethane elastomer.
