Abstract: An acrylic resin composition includes an acrylic resin and a graft copolymer. The graft copolymer includes an inner layer and an outer layer. The inner layer is a soft polymer (B) having, as structural units, a monomer mixture (b) containing 40 to 99 wt % of an alkyl acrylate ester, 1 to 60 wt % of benzyl (meth)acrylate, and 0 to 40 wt % of another monomer and 0.1 to 5 parts by weight of a polyfunctional monomer; and the outer layer is a hard polymer (C) having, as structural units, a monomer mixture (c) containing 60 to 100 wt % of an alkyl methacrylate ester, 0 to 10 wt % of benzyl (meth)acrylate, and 40 to 0 w % of another monomer and 0 to 10 parts by weight of a polyfunctional monomer.
