    摘要: To provide a protective film for a polarizing plate that shows a water vapor transmission rate (WVTR40) of 30 g/m2·day or less at 60° C. and a relative humidity of 40%, a water vapor transmission rate (WVTR95) 80 g/m2·day or more and 300 g/m2·day or less at 60° C. and a relative humidity of 95% and a value obtained by dividing the difference between WVTR95 and WVTR40 by the water vapor transmission rate (WVTR60) at 60° C. and a relative humidity of 60%, or (WVTR95-WVTR40) /WVTR60, 2.0 or more.
