PURPOSE:To form a coating film of a large adhesive force on the surface of a molding of a composition comprising a specified polyamide and a Zn ion-crosslinked ionomer. CONSTITUTION:A molding is produced from a composition prepared by mixing 100pts.wt. polyamide having a ratio of the concentration of the terminal carboxyl groups to that of the terminal amino groups of at least 1.5 with 1- 400pts.wt. Zn ion-crosslinked ionomer and, optionally, 1-15pts.wt. ethylene/ propylene/diene rubber of a propylene content of 10-50wt% and at most 150pts.wt. inorganic filler (e.g., talc). The surface of this molding is coated with a plastic resin paint (e.g., melamine-alkyd paint) to form a coating film thereon.
