<p>PROBLEM TO BE SOLVED: To obtain an acrylic film which exhibits a good processibility even when subjected to bending, etc., at a high speed by producing it from a compsn. comprising a specific acrylic-rubber-contg. polymer having specified gel content, a particle size and a Ca content and an acrylic thermoplastic polymer having a specified glass transition temp. and a wt. average mol.wt. and formed from a methacrylic ester having an alkyl group having a specified number of carbon atoms and by imparting specified gel content and elongation at break to the film. SOLUTION: This film is produced from a compsn. comprising 70-95 pts.wt. acrylic-rubber-contg. polymer having a gel content of 60 wt.% or higher, a particle size of 0.08-0.16μm and a Ca content of 50-500 ppm and 5-30 pts.wt. acrylic thermoplastic polymer having a glass transition temp. lower than 70 deg.C and a wt. average mol.wt. of 100,000-300,000 and formed from 50-100 wt.% methacrylic ester having a 1-4C alkyl group, 50 wt.% or lower optional acrylic ester and 50 wt. % or lower optional copolymerizable monomer and has a gel content of 50-70 wt.% and an elongation at break in one direction of 180% or higher.</p> |
