Abstract: An acrylic resin film is provided that may include graft copolymer particles (A) with a multilayer structure and graft copolymer particles (B) with a multilayer structure, wherein the graft copolymer particles (A) may have an average particle size in the range of 20 to 150 nm, the graft copolymer particles (B) may have a larger average particle size than the graft copolymer particles (A). The graft copolymer particles (A) may include a cross-linked elastomer (A1) and a graft polymer layer (A2), the graft polymer layer (A2) being closer to a surface layer than the cross-linked elastomer (A1). Further, a constituent unit may be derived from an acrylate with an alkyl ester moiety having two or more carbon atoms constitutes 8% or less by mass of the graft polymer layer (A2), the graft copolymer particles (B) may contain a cross-linked elastomer (B1).

Abstract: A laminate having excellent moldability and including an acrylic-based resin film is provided. A method for producing a laminate having a specific crack elongation, includes a step (A) of forming, on at least one side of a specific acrylic-based resin film, a hard coat layer that contains a urethane acrylate resin, and a step (B) of forming, on the hard coat layer obtained in the step (A), a low refractive index layer that contains, in an amount of not less than 40%, hollow fine silica particles having a particle size of less than 100 nm and that contains an acrylate-based resin.

Abstract: Provided is a laminate that has excellent moldability and excellent wear resistance, and that contains an acrylic-based resin film. Excellent mouldability and wear resistance can be attained by providing a laminate including a specific acrylic-based resin film, and a specific ultraviolet-curable hard coat layer that is laminated on at least one side of the acrylic-based resin film. The laminate has a specific crack elongation and exhibits a Δhaze of not more than 1.0% in a steel wool wear test at 50 g/cm2 and 5 reciprocating motions.
