Acrylic resin film, laminated film, production method for laminated film, and molded article

An acrylic resin film comprising graft copolymer particles (A) with a multilayer structure and graft copolymer particles (B) with a multilayer structure, wherein:

• the graft copolymer particles (A) have an average particle size in a range of 50 to 100 nm,
• the graft copolymer particles (B) have a larger average particle size than the graft copolymer particles (A),
• the graft copolymer particles (A) include:
• a cross-linked elastomer (A1) in an amount of 20 to 40 parts by mass compared to 100 parts by mass (A), comprising:
• one or more acrylate constituting 80% or more by mass of (A1) selected from the group consisting of ethyl acrylate, propyl acrylate, butyl acrylate, isobutyl acrylate, and 2-ethyl-hexyl acrylate,
• one or more other vinyl monomer copolymerizable with the acrylate of (A1) constituting 1% to 19.9% by mass of (A1) selected from a methacrylate, and
• one or more polyfunctional monomer constituting 0.1% to 10% by mass of (A1) selected from the group consisting of allyl methacrylate, allyl acrylate, diallyl phthalate, divinyl adipate, divinyl benzene, ethylene glycol dimethacrylate, and propylene glycol dimethacrylate;
• and
• a graft polymer layer (A2) in an amount of 60 to 80 parts by mass compared to 100 parts by mass (A), comprising:
• an alkyl methacrylate constituting 80% to 99% by mass of the graft polymer layer (A2), and
• a constituent unit derived from an acrylate with an alkyl ester moiety having two or more carbon atoms constitutes 1% to 8% mass of the graft polymer layer (A2);
• the graft polymer layer (A2) being closer to a surface layer than the cross-linked elastomer (A1),
• the graft copolymer particles (B) contain:
• a core comprising one or more cross-linked elastomer (B1),
• wherein the core comprises methyl methacrylate, butyl acrylate, allyl methacrylate, and styrene,
• wherein the core comprises a two-layer, or a three-layer structure, and the core comprises a hard polymer layer,
• an amount of constituent units derived from the methyl methacrylate and the styrene is 40.7% to 49.9% by mass of (B1), and
• an amount of a constituent unit derived from the allyl methacrylate is 0.1% to 10% by mass of (B1),
• conditions 1) and 2) that follow are satisfied:
• 1) a total amount of the cross-linked elastomer (A1) and the cross-linked elastomer (B1) in the acrylic resin film is 12 to 15 parts by mass per 100 parts by mass of the acrylic resin film, and
• 2) an amount of the cross-linked elastomer (B1) is 1.5 parts or more and 7 parts or less by mass per 100 parts by mass of the acrylic resin film,
• a thickness of the acrylic resin film is in a range of 40 to 300 μm, and
• when tested according to a cutter evaluation, the acrylic resin film has from 2 to 34 cracks that are 1 mm or more in length.
