Patent number: 10829668Abstract: The present application relates to a pressure-sensitive adhesive composition, a protective film, an optical element and a display device. The pressure-sensitive adhesive composition of the present application has excellent storage stability, exhibits an appropriate low-speed and high-speed peel forces after the cross-linked structure is formed, and has excellent balance of both. Furthermore, the pressure-sensitive adhesive formed by the pressure-sensitive adhesive composition does not leave contaminants in the adherend after peeling, while exhibiting re-detachability. Accordingly, when the pressure-sensitive adhesive composition is applied to, for example, a protective film, it is also advantageous in terms of high-speed processes by being easily peeled off upon high-speed peeling as well as it exhibits an excellent protective effect, thereby being capable of exhibiting excellent antistatic characteristics.Type: GrantFiled: December 7, 2016Date of Patent: November 10, 2020Assignee: LG Chem, Ltd.Inventors: Sang Ha Son, Jeong Sik Bae, Jeong Ae Yoon, Sung Soo Yoon
