In a molded composite article formed by directly bonding a resin member comprising a polyamide-series resin to a resin member comprising a thermoplastic polyurethane-series resin, the polyamide-series resin comprises a polyamide block copolymer containing (A) a polyether segment having at least one terminal imino group. The polyamide-series resin may comprise a polyamide-series resin having a free amino group in a concentration of not less than about 10 mmol/kg. The molded composite article is producible, for example, by heating at least one of the polyamide-series resin and the thermoplastic polyurethane-series resin to bond the former to the latter. Thus obtained molded composite article is suitable for a member of a shoe and an industrial roll. In such a process, the polyamide-series resin member and the thermoplastic polyurethane-series resin member both of which are different in nature from each other can be directly and firmly bonded together.
A molded composite article which comprises (Ia) a resin member comprising a polyamide resin and (IIa) a resin member which is directly bonded to the resin member (Ia) and comprises a thermoplastic polyurethane resin, wherein the polyamide resin comprises a polyamide block copolymer containing (A) a polyether segment having at least one terminal —NH— group, and the thermoplastic polyurethane resin comprises a polyester polyurethane obtained from a polyester diol.
