发明名称 MULTILAYER MOLDED ARTICLE AND METHOD FOR PRODUCING THE SAME
摘要 The present invention is directed to a multilayer molded article produced using a composite skin layer made of a skin material and a foam sheet on a core layer of a thermoplastic resin in which tensile modulus E of the skin material is not larger than 950 kg/cm2, and tensile modulus E (kg/cm2), heat shrinkage factor F (%) and thickness t (cm) of the skin material satisfy the following relationship: 20/(E x t) + F .gtoreq. 2.5. This produces a large size multilayer molded article having a complicated shape and no wrinkles, breakage or uneven marks in the skin material on the surface of the article.
