wherein in Equation 1b,
TS0 refers to the modulus before the film is treated in an autoclave, and
TS24 refers to the modulus after the film is treated in an autoclave, and the autoclave treatment means that an autoclave is filled with water and a film is treated therein at a temperature of 120° C. and a pressure of 1.2 atm for 24 hours,
wherein a content of a residual solvent in the film is 1,200 ppm or less,
wherein an IS value represented by the following Equation 7 is 5 to 160:, IS
