Abstract
An acrylic thermoplastic resin composition is obtained by melt-kneading a methacrylic resin (A) and a polyvinyl acetal resin (B) at a resin temperature of not less than 140° C. while applying shear at a shear rate of 100 secor more, and then cooling the kneaded product to not more than 120° C. In the acrylic thermoplastic resin composition, at least the methacrylic resin (A) forms a continuous phase, and among glass transition temperatures of the acrylic thermoplastic resin composition, a glass transition temperature Tgascribed to the methacrylic resin (A) indicates a value between a glass transition temperature (Tg) of the methacrylic resin (A) alone and a glass transition temperature (Tg) of the polyvinyl acetal resin (B) alone. A film- or sheet-like molded article is obtained by molding the resin composition. An acrylic resin composite is obtained by laying a layer of metal and/or metal oxide on at least one side of the acrylic resin molded article.
