Abstract:
1. An acrylic resin film comprising, an acrylic thermoplastic resin composition, comprising: a methacrylic resin (A); and a polyvinyl acetal resin (B), wherein the methacrylic resin (A) has a weight average molecular weight of 40,000 or more, a methyl methacrylate unit content in the methacrylic resin (A) is 80 to 99.9% by mass, an alkyl acrylate unit in the methacrylic resin (A) is 0.1 to 20% by mass, at least the methacrylic resin (A) forms a continuous phase, and among glass transition temperatures of the acrylic thermoplastic resin composition, a glass transition temperature, Tg wherein a mass ratio, (A)/(B), of the methacrylic resin (A) to the polyvinyl acetal resin (B), is 99/1 to 51/49.
