Antistatic adhesive optical film and image display

摘要

The present invention aims at providing an antistatic pressure-sensitive adhesive optical film exhibiting excellent antistatic effect, optical properties, and water resistance and having excellent adhesion between the antistatic layer and the pressure-sensitive adhesive layer. An antistatic pressure-sensitive adhesive optical film, the optical film having an antistatic layer laminated on at least one side of the optical film, and a pressure-sensitive adhesive layer further laminated on the antistatic layer, wherein the antistatic layer comprises a conductive polymer and a sulfonic acid compound as raw material components, and the pressure-sensitive adhesive layer is formed of an acryl-based pressure-sensitive adhesive containing nitrogen.
