ACRYLIC RESIN FILM FOR ELECTRON BEAM IRRADIATION

PROBLEM TO BE SOLVED: To provide an acrylic resin film for electron beam irradiation, which is prevented from yellowing after electron beam irradiation and has improved impact resistance and weatherability. SOLUTION: The acrylic resin film for electron beam irradiation is obtained by molding an acrylic resin composition containing a (meth)acrylic resin including acrylic rubber particles and a triazine compound as an ultraviolet absorber. The acrylic rubber particles (a) are obtained by copolymerizing 95-15 pts.wt. of a monomer mixture (a-2) comprising 50-100 wt.% of a methacrylic acid alkyl ester and 0-50 wt.% of other copolymerizable vinyl-based monomer in the presence of 5-85 pts.wt. of an acrylic acid ester-based cross-linked elastomer of at least one layer, wherein the acrylic acid ester-based cross-linked elastomer is obtained by polymerizing a monomer mixture (a-1) comprising 50-99.9 wt.% of an acrylic acid ester, 0-49.9 wt.% of other copolymerizable vinyl-based monomer, and 0.1-10 wt.% of a polyfunctional monomer having at least two copolymerizable non-conjugated double bonds in one molecule.
