Kind Code:
A1
Abstract:
A pressure sensitive adhesive composition characterized by containing an ionic liquid and a water dispersible (meth)acrylic polymer in which 50 to 99.9 wt.% of (meth)acrylate having a C1-C14 alkyl is contained as a monomer component. Accordingly, 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.
