Abstract:
A pressure-sensitive adhesive composition characterized by comprising a water-dispersible (meth)acryl-based polymer containing, as a monomer component, 50 to 99.9% by weight of a (meth)acrylate having an alkyl group with a carbon number of 1 to 14, and an ionic liquid. There is provided a pressure-sensitive adhesive composition that attains static charge prevention at peeling between pressure sensitive adhesive layer and adherend not rendered antistatic, thereby reducing contamination of the adherend. Also, there are provided, making use of the same, an antistatic pressure sensitive adhesive sheet and surface protective film.
