Abstract:
An acrylic resin film is provided that may include graft copolymer particles (A) with a multilayer structure and graft copolymer particles (B) with a multilayer structure, wherein the graft copolymer particles (A) may have an average particle size in the range of 20 to 150 nm, the graft copolymer particles (B) may have a larger average particle size than the graft copolymer particles (A). The graft copolymer particles (A) may include a cross-linked elastomer (A1) and a graft polymer layer (A2), the graft polymer layer (A2) being closer to a surface layer than the cross-linked elastomer (A1). Further, a constituent unit may be derived from an acrylate with an alkyl ester moiety having two or more carbon atoms constitutes 8% or less by mass of the graft polymer layer (A2), the graft copolymer particles (B) may contain a cross-linked elastomer (B1).
