摘要：
A pressure-sensitive adhesive optical film of the present invention comprises an optical film; and a pressure-sensitive adhesive layer laminated on at least one side of the optical film, wherein the pressure-sensitive adhesive layer is formed from an acrylic pressure-sensitive adhesive comprising a (meth)acrylic polymer comprising 30 to 99.99% by weight of an alkyl(meth)acrylate monomer unit and 0.01 to 15% by weight of a functional group-containing monomer unit, and the (meth)acrylic polymer in the acrylic pressure-sensitive adhesive is crosslinked by electron beam irradiation. The pressure-sensitive adhesive optical film has a high level of reworkability, durability and workability.
