摘要: A multilayer article such as a door trim board is fabricated by the steps of extruding melted resin layers (13m), (12m) and (11m) respectively forming a soft skin material (13), a foamed soft intermediate layer (12) and a base member (11) in the form of a multilayer resin sheet from a die-head (40) of an extruding machine, supply the extruded multilayer resin sheet to a molding machine in such a manner that the resin layer for the skin material is placed on a lower molding die of the molding machine and molding the resin layers in the form of the multilayer article. The resin layer for the skin material consists of thermoplastic elastomer, the resin layer for the intermediate layer consists of ethylenic copolymer copolymerized with ethylene and at least radical copolymerizable acid anhydride, and the resin layer for the base member consists of olefinic resin. The thermoplastic elastomer for the skin material is prepared in the form of olefinic thermoplastic elastomer and/or styrenic thermoplastic elastomer The melting flow rate of the thermoplastic elastomer is determined to be 0.1-200 g/10 min at 230.degree. C. under load of 2.16, and the shore A hardness of the elastomer is determined to be in a range of 50-96.
