摘要： Disclosed herein is an acrylic resin film that is less likely to whiten on bending when laminated on a plastic molded body or the like, has well-balanced physical properties such as high surface hardness, excellent transparency, and excellent cracking resistance, and is therefore suitable for use in decorative molding. The acrylic resin film is obtained by forming, into a film, a methacrylic resin composition (D) containing a specific methacrylate-based resin (A), a rubber-containing four-stage graft copolymer (B) containing rubber particles having an average particle size of 0.2 to 0.4 μm, and a rubber-containing two-layer graft copolymer (C) containing rubber particles having an average particle size of 0.02 to 0.15 μm.

摘要： The present invention provides a (meth)acrylic resin composition comprising a carboxylic acid group produced by heating a (meth)acrylic-based resin (C), wherein the (meth)acrylic-based resin (C) is obtained by polymerizing a monomer mixture (A) containing 80 to 99 wt % of a linear alkyl (meth)acrylate and 1 to 20 wt % of tertiary-butyl (meth)acrylate, in the presence of an acrylic acid ester-based crosslinked elastic particle (B) that is obtained by mixing and polymerizing 0.5 to 5 parts by weight of a polyfunctional monomer having at least two non-conjugated double bonds per molecule, with respect to 100 parts by weight of a monomer mixture containing 50 to 100 wt % of an alkyl acrylate monomer and 0 to 50 wt % of an alkyl methacrylate monomer. This composition can be used to produce a film having excellent chemical resistance (in particular, sun-screening agent resistance).
