Zusammenfassung:Provided is an acrylic resin composition capable of yielding a molded article or film having exceptional mechanical characteristics such as impact resistance and bending resistance, exceptional transparency or color tone, and suppressed retardation. In a resin composition including an acrylic resin and a graft copolymer, the graft copolymer includes the following inner layer and outer layer. Innerlayer: soft polymer (B) having, as structural units: a monomer mixture (b) comprising 40-99% by weight of an acrylic acid alkyl ester, 1-60% by weight of benzyl (meth)acrylate, and 0-40% by weight ofother monomers; and 0.1-5 parts by weight of polyfunctional monomers. Outer layer: hard polymer (C) having, as structural units: a monomer mixture (c) comprising 60-100% by weight of a methacrylic acid alkyl ester, 0-10% by weight of benzyl (meth)acrylate, and 40-0% by weight of other monomers; and 0-10 parts by weight of polyfunctional monomers. 本发明提供种丙烯酸系树脂组合物,其能够形成耐冲击性、耐弯折性等机械特性及透明性或色调优异且抑制了相位差的成型体或膜。在含有丙烯酸系树脂和接枝共聚物的树脂
