Abstract
A film is obtained by forming a methacrylic resin composition comprising 100 parts by mass of a methacrylic resin (A) and preferably 1 to 10 parts by mass of a polycarbonate resin, the methacrylic resin (A) having a triad syndiotacticity (rr) of not less than 58%, a weight average molecular weight of 50000 to 150000, a content of fraction having a molecular weight of not less than 200000 of 0.1 to 10% by mass and a content of fraction having a molecular weight of less than 15000 of 0.2 to 5% by mass. A polarizer protective film comprising the above film is obtained.
