An object of the present invention is to provide a pressure sensitive adhesive composition for an optical member, which is excellent in coating property because of low viscosity, can reduce an amount of an organic solvent used, and can form a pressure sensitive adhesive layer excellent in durability and having high surface uniformity. The present invention relates to a pressure sensitive adhesive composition for an optical member, which comprises a (meth)acrylic polymer, a C6 to C9 hydrocarbon-based solvent (A), and a high-boiling highly solubilizing solvent (B) having a boiling point higher than that of the above hydrocarbon-based solvent and having a higher ability to solubilize the (meth)acrylic polymer than that of the above hydrocarbon-based solvent, wherein a content of the hydrocarbon-based solvent (A) is 20 to 60 wt % based on the total amount of the solvents, and a ratio of the content (wt %) of the hydrocarbon-based solvent (A) to the content (wt %) of the high-boiling highly solubilizing solvent (B) (high-boiling highly solubilizing solvent (B)/hydrocarbon-based solvent (A)) is 0.05 to 4.

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.
