发明名称 MULTILAYERED INJECTION MOLDED OBJECT
摘要 PROBLEM TO BE SOLVED: To provide a multilayered injection molded object composed of a polyolefinic resin compsn. wherein a skin layer on the side of a design surface develops gloss or a depth feeling and scratch resistance equal to those of a coating film or a clear layer. SOLUTION: In a multilayered injection molded object consisting of a core layer composed of a polyolefinic resin compsn. and the skin layer applied to the periphery of the core layer, the skin layer is composed of a polyolefinic resin compsn. having characteristics (A) wherein the average thickness of the skin layer on the side of the design surface of the multilayered injection molded object is 20% or less of the average thickness of the molded object and characteristics (B) wherein the linear light transmissivity of the injection molded object obtained by the injection molding of the polyolefinic resin compsn. constituting the skin layer by using a mold having the same thickness as the skin layer on the side of the design surface of the multilayered injection molded object is 20% or more.
