Abstract:

This acrylic resin film is formed as a result of containing: an acrylic multilayer polymer (A) comprising an outer layer comprising a thermoplastic polymer (III) and a layer of a crosslinked elastomer that is adjacent to and covers the outer layer; a methacrylic resin (B) that contains 99 mass% or more of methyl methacrylate units and has a weight average molecular weight of 50,000-200,000; and an ultraviolet radiation absorber (C) having a hydroxyphenyltriazine skeleton. The content of the ultraviolet radiation absorber (C) is 0.1-1.5 mass% relative to the total amount of the acrylic multilayer polymer (A) and the methacrylic resin (B). The layer of a crosslinked elastomer has an intermediate layer comprising a crosslinked rubber polymer (II) and an inner layer which comprises a crosslinked polymer (I) and is adjacent to and covers the intermediate layer. The layer of a crosslinked elastomer has an average diameter of 120 nm or less. The amount of acetone-insoluble components in the film is 35-55 mass%.
