Abstract: Provided is a pressure-sensitive adhesive composition. The pressure-sensitive adhesive composition may form a pressure-sensitive adhesive having a fine phase separation structure by a block copolymer including a hard segment and a soft segment, and also has a high elastic modulus and an excellent pressure-sensitive adhesive property. For example, although applied to a thin polarizing plate on at least one surface of which a polarizer protective film is not used, the pressure-sensitive adhesive may allow the polarizing plate to exhibit excellent durability, moisture resistance, workability, a pressure-sensitive adhesive property and a light leakage inhibiting ability.

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.
