Abstract

Provided are a pressure sensitive adhesive composition, a protective film, an optical film and a display device. The pressure sensitive adhesive composition shows appropriate low-speed and high-speed peel strengths after formation of a cross-linked structure, and has a superior balance between the two. Accordingly, when the pressure sensitive adhesive composition is applied to a protective film, for example, a superior protection effect as well as easy peel-off upon high-speed peeling, which is advantageous for a high-speed process, are shown, and in addition, a superior antistatic property may be obtained during the process.
