Abstract:
A method for the production of a molded article comprising the steps of:inserting in between male and female molds an acrylic film or sheet, made from a resin composition comprising 95 to 50 wt. % of an acrylic resin which comprises methyl methacrylate as a main component and has a glass transition temperature in the range of 40 to 105.degree. C., and 5 to 50 wt. % of a three-layer-structured acrylic polymer consisting of an innermost layer made from a hard polymer comprising methyl methacrylate as a main component, an intermediate layer made from a soft elastomer comprising a copolymer of a polyfunctional monomer and an alkyl acrylate having 4 to 8 carbon atoms in the alkyl group, and an outermost layer made from a hard polymer comprising methyl methacrylate as a main component, wherein the three-layer-structured polymer is dispersed in the acrylic resin, andinjection molding a thermoplastic resin in the molds so that said acrylic film or sheet is simultaneously laminated to the surface of the molded material obtained.
