The present invention provides a release material formed by irradiating a release material precursor having a shear storage modulus of about 1×102 to about 3×106 Pa at 20° C. and a frequency of 1 Hz, wherein the release material has a contact angle of 15° or more, measured using a mixed solution of methanol and water (volume ratio: 90/10) having a wet tension of 25.4 mN/m. The release material of the present invention has improved anchoring to certain substrates, ensuring relatively low release strength from certain pressure-sensitive adhesives, particularly even after the exposure to a high temperature. Thus, the release materials are capable of allowing the pressure-sensitive adhesive to maintain stable residual adhesion strength.
