Abstract

To provide an adhesive composition enabling formation of an adhesive layer having improved durability, an adhesive sheet containing an adhesive layer formed with the adhesive composition, and an optical film produced from the adhesive sheet.SOLUTION: An adhesive composition according to an embodiment of the present invention comprises an acrylic copolymer, a crosslinking agent, an alkylene oxide group-containing (meth)acrylate compound, and an ionic antistatic agent having an imidazolium cation and a bis(fluorosulfonyl)imide anion. An adhesive layer formed from the adhesive composition exhibits high adhesion to a substrate film and can provide an optical film with improved reworkability even after prolonged exposure to harsh conditions including high temperature and high humidity.SELECTED DRAWING: Figure 1
