Abstract

An acrylic resin film comprising 50 to 99 parts by mass of a methacrylic resin (A) comprising not less than 80% by mass of a structural unit derived from methyl methacrylate, and 50 to 1 part by mass of a block copolymer (B) comprising 40 to 90% by mass of methacrylic acid ester polymer block[s] (b1) and 10 to 60% by mass of acrylic acid ester polymer block[s] (b2), provided that the total of the methacrylic resin (A) and the block copolymer (B) is 100 parts by mass, wherein the methacrylic resin (A) and the block copolymer (B) satisfy the inequations (1) and (2):0.5≤Mw/Mw≤2.3  (1)30000≤Mw≤120000  (2)in which Mwis the weight average molecular weight of the methacrylic resin (A), Mwis the largest weight average molecular weight among the methacrylic acid ester polymer block[s] (b1) and Mwis the largest weight average molecular weight among the acrylic acid ester polymer block[s] (b2).
