摘要: Disclosed is a paint protection film having a storage modulus measured at a temperature of n ° C. according to ASTM D4065 of En, where n is a number representing a temperature in degrees Celsius, wherein E40/E20 is 0.75 or more and 1.1 or less, wherein the paint protection film has a change index dYI of yellowness according to ASTM E313 before and after a UV irradiation, represented by Equation 1 below, of 0.8 or less, where the UV irradiation is performed for 72 hours at an output of 3 W with a light having wavelength from 280 nm to 360 nm:
dYI=|YI−UV_YI| [Equation 1]
in Equation 1, YI is the yellowness of the paint protection film before the UV irradiation, and UV_YI is the yellowness of the paint protection film after the UV irradiation.-
