Abstract
The present invention provides a process for producing a multilayer molded article having a skin material laminated with at least a part of the surface of a substrate formed of a thermoplastic resin. The process has steps of supplying a skin material to between a pair of mold halves and supplying a molten thermoplastic resin to between the skin material and the molding surface of one of the mold halves. The process uses, as the skin material, a skin material which has at least a foamed urethane layer and a nonfoamed backing layer wherein the product of the density, &rgr; (g/cm ), of the foamed urethane layer and the weight, W (g/m ), of the backing layer is not less than 2. This process prevents crush of the foamed urethane layer and can produce a multilayer molded article with good appearance.
