Disclosed are hollow polymer spheres prepared from one or more hydrophilic ethylenically unsaturated monomers containing acid functionality, one or more nonionic hydrophilic ethylenically unsaturated monomers, and one or more hydrophobic ethylenically unsaturated monomers. Disclosed is a process for preparing such hollow spheres. The hollow spheres exhibit controlled particle size, which can have larger particle sizes, narrow particle size distributions and high void volume percentages.

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 m, and a rubber-containing two-layer graft copolymer (C) containing rubber particles having an average particle size of 0.02 to 0.15 m.
