Abstract:
1. An article of manufacture, comprising: a substrate; and a capstock laminated with said substrate, said capstock being made from a resin composition for capstock, comprising: 80 to 40 parts by weight of an impact resistance modifier having a multilayer structure, and 20 to 60 parts by weight of a methyl methacrylate (co)polymer containing 50 to 100% by weight of methyl methacrylate and 50 to 0% by weight of a monomer(s) which is copolymerizable therewith, wherein the total amount of the impact resistance modifier and the methyl methacrylate (co)polymer is 100 parts by weight, wherein the outer layer of said impact resistance modifier and/or said methyl methacrylate copolymer is copolymerized with 0.5 to 40% by weight of reactive monomer(s) based on the total amount of the impact resistance modifier and the methyl methacrylate (co)polymer as a polymer component, wherein said reactive monomer is one or more monomer(s) selected from acrylonitrile, methacrylonitrile, glycidyl methacrylate, 2-hydroxyethyl acrylate, 2-hydroxyethyl methacrylate, 4-hydroxybutyl acrylate, acrylic acid, and methacrylic acid, wherein the homopolymer of said reactive monomer has an SP value of 9.8 (cal/cm wherein the impact resistance modifier has a two-layer structure and is obtained by polymerizing a monomer mixture containing (meth)acrylic ester(s) and copolymerizable monomer(s) in the presence of a crosslinked acrylic rubber.
