摘要:
To provide an acrylic film, composed of a resin composition (C) that includes an acrylic graft copolymer (A) containing an acrylic ester rubber-like polymer and a methacrylic polymer (B) containing 80% by weight or more of methyl methacrylate, wherein (1) the content of the acrylic ester rubber-like polymer in the resin composition (C) is 5% by weight or more and 30% by weight or less, (2) the average particle size of the acrylic ester rubber-like polymer is 500 to 2000 Å, (3) the relationship between the average particle size d (Å) of the acrylic ester rubber-like polymer and the amount w (% by weight) of crosslinking agent used in the acrylic ester rubber-like polymer satisfies the following equation: 0.002d≦w≦0.005d, (4) the graft ratio of the acrylic graft copolymer (A) is 30% or more and 200% or less, and (5) the reduced viscosity of methyl ethyl ketone soluble matter in the resin composition (C) is 0.2 to 0.8 dl/g.
