An acrylic resin composition suitable for use as films excellent in transparency, weatherability, hardness, impact resistance, flex cracking resistance, and formability. The resin composition comprises an acrylic graft copolymer (A) including a rubbery acrylic ester polymer (A-a) and a methacrylic polymer (B) comprising 80 wt.% or more methyl methacrylate units, the acrylic resin composition having a specific value of reduced viscosity (0.2-0.8 dl/g), specific values of content (5-45 wt.%) and average particle diameter (50-200 nm) of the rubbery polymer (A-a), a specific relationship between the particle diameter and the crosslinking agent amount (0.02d‰ w‰ 0.05d; d, average particle diameter (nm) ; w, amount of crosslinking agent (wt.%)), and a specific value of the degree of grafting (50-2500). The resin composition contains an ultraviolet absorber incorporated therein through copolymerization. |
