<P>PROBLEM TO BE SOLVED: To provide a polarizer plate protection film which can be bonded to a polarizer at a high speed by using a photo-curable adhesive without sucking air, and has high heat resistance and adhesion to the polarizer, and to provide a polarizer plate having the polarizer plate protection film. <P>SOLUTION: The polarizer plate protection film includes: cellulose ester (A) satisfying 2.00≤DSac(A)+DSay(A)≤2.90, 1.50≤DSay(A)≤2.80, 1000≤Mw(A)≤80000, 120°C≤Tg(A)≤147°C; and cellulose ester (B) satisfying 2.00≤DSac(B)≤2.90, 100000≤Mw(B)≤300000, 150≤Tg(B)≤190. The content mass ration of the cellulose ester (A) and (B) is in a range of 1:99 to 30:70, and a glass transition temperature Tg of the polarizer plate protection film is in a range of 148 to 190°C. <P>COPYRIGHT: (C)2013,JPO&INPIT |
