发明名称 Multilayer molded articles and process for producing the same.
摘要 <p>A multilayer molded article comprising a skin and a substrate consisting of a polypropylene resin composition having a crystallization rate of 45 second or less, said skin being integrally adhered to the substrate. Said multilayer molded article can be produced by feeding a skin material and a molten polypropylene resin composition having a crystallization rate of 45 second or less between a pair of upper and lower molds, molding the molten polypropylene resin composition in the molds with simultaneous adhering of the skin material to the surface of the molded resin composition and then cooling the molten resin composition to solidify the same. Said multilayer molded article has a small deformation degree without the soft feeling of the skin material being impaired. &lt;IMAGE&gt;</p>
