Abstract:
A method for producing a multi-layer molded article comprising a skin material layer made of a vinyl chloride resin, a propylene resin core, and an adhesive layer present between said skin material layer and said core, in which said adhesive layer comprises:(A) a layer having(a) a first sublayer comprising 30 to 90 wt. % of a polyester resin, and a rest of an epoxy group-containing ethylene copolymer and optionally an ethylene copolymer, which is bonded to said skin material of the vinyl chloride resin, and(b) a second sublayer comprising at least one copolymer selected from the group consisting of an ethylene copolymer and an epoxy group-containing copolymer, and optionally a polyolefin, which is bonded to said propylene resin core,or(B) a layer obtained from an ethylene resin composition comprising 100 wt. parts of an epoxy-group containing copolymer (c) which comprises 20 to 99.9 wt. % of ethylene units, 0.1 to 30 wt. % of unsaturated carboxylic acid glycidyl ester units or unsaturated glycidyl ether units, and 0 to 50 wt. % of an ethylenically unsaturated ester units other than the unsaturated carboxylic acid glycidyl ester units, 0.1 to 50 wt. parts of a polybasic carboxylic acid having at least two carboxyl groups, and optionally 0.1 to 20 wt. parts of a heat decomposable blowing agent, which method comprises steps of:laminating a composite layer of said vinyl chloride resin skin material and said adhesive layer which are integrally laminated, on said propylene resin which has been preheated to a temperature higher then its melting point, with said adhesive layer of said composite layer facing said propylene resin, andpressing them, andwherein said composite layer is produced by powder slush molding.
