Abstract:
A surface protection film-attached optical film of the invention comprises: an optical film; and a surface protection film that comprises a substrate film and a pressure-sensitive adhesive layer and is provided on the surface of, the optical film through the pressure-sensitive adhesive layer, wherein a surface of the optical film in contact with the pressure-sensitive adhesive layer is activated by treatment, and the pressure-sensitive adhesive layer of the surface protection film contains an ionic antistatic agent. The surface protection film-attached optical film can reduce the amount of peeling electrostatic charge which can be generated when the surface protection film is peeled off from the optical film, and can be free from the problem of optical film surface contamination after the surface protection film is peeled off.
