NOVELTY - A methacrylic resin film comprises resin composition comprising acrylic acid ester crosslinked elastic component particles (B) obtained by copolymerizing polyfunctional monomer (b2) having 2 or more nonconjugated double bonds and monomer mixture (b1) containing 0-50 weight% of methacrylic acid alkylester, and methacrylic resin (C) obtained by polymerizing monomer mixture containing 0-50 weight% of acrylic acid alkylester. Weight average molecular weight of methyl-ethyl-ketone soluble portion of component (C) is 50000-120000 based on polystyrene conversion.    USE - Methacrylic resin film is used for lamination sheet (claimed). Uses include but are not limited to solar cell surface protection film, mobile telephone, window frame, wallpaper, flooring, optical disk, light-guide plate for liquid crystal, housing of domestic electrical appliance, microwave oven cooking vessel and lens for illumination.    ADVANTAGE - The lamination sheet formed using the methacrylic resin film has excellent heat shrinkage property.    DETAILED DESCRIPTION - A methacrylic resin film comprises a resin composition comprising acrylic acid ester crosslinked elastic component particles (B) (18-40 weight%) obtained by copolymerizing polyfunctional monomer (b2) having 2 or more nonconjugated double bonds in a molecule and monomer mixture (b1) containing 0-50 weight% of methacrylic acid alkylester in presence of acrylic acid alkylester (50-100 weight%) and methacrylic acid alkylester (50-100 weight%), and methacrylic resin (C) obtained by polymerizing monomer mixture containing 0-50 weight% of acrylic acid alkylester. The methacrylic resin film having thickness of 40-75 mu m, has shrinkage rate of 21% or less in flow direction of the film after heating at 150 degrees C. The methacrylic resin (C) is two-layered structure polymer containing component (B) and methacrylic acid ester polymer (A). The content of polyfunctional monomer (b2) is 0.1-5 weight% with respect to 100 weight% of monomer mixture (b1), in component (B). The weight average molecular weight of methyl-ethyl-ketone soluble portion of component (C) is 50000-120000 based on polystyrene conversion. The average particle diameter of component (B) is 0.04-0.3 mu m. The copolymerization amount (bm) and weight average molecular weight (Mw) of polyfunctional monomer (b2) in component (B) satisfies a relation: (Mw/10000)/bm=3-8. An INDEPENDENT CLAIM is included for methacrylic resin lamination sheet, which is obtained by laminating methacrylic resin film on a thermoplastic resin sheet.
