<P>PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive composition excellent in adhesion reliability from which the charging prevention on the release of an adherend can be achieved and the contamination to the adherend is decreased, a pressure-sensitive adhesive sheet of an antistatic property, and a surface protective film, using the same. <P>SOLUTION: This pressure-sensitive adhesive composition is characterized by containing an ionic liquid presenting a liquid form at room temperature (25°C), and a polymer that has 0.1-10 wt.% of a (meth)acrylic acid ester having a 3-12C hydroxyalkyl group as a monomer unit, where the composition further includes 0.01-10 pts.wt. of a surfactant having an ether group based on 100 pts.wt. of the polymer, and the ionic liquid contains one or more kinds of cations shown by general formulas (A) to (D). <P>COPYRIGHT: (C)2013,JPO&INPIT |
