Zusammenfassung:Embodiments provide a paint protection film, in which a storage modulus measured at a temperature of n DEG C according to ASTM D4065 is En, where n is a number representing a temperature in degrees Celsius, E40/E20 is 0.75 or more and 1.1 or less, a tear strength is 500 gf or more and 800 gf or less, a change index dYI of yellowness according to ASTM E313 before and after UV irradiation, represented by Equation 1 below, is 0.8 or less, and, the UV irradiation is performed for 72 hours at an output of 3 W with light of any one wavelength from 280 nm to 360 nm [Equation 1] dYI = | YI - UV_YI | in Equation 1, YI is the yellowness of a paint protection film before the UV irradiation, and UV_YI is the yellowness of a paint protection film after the UV irradiation.
