The present invention provides a pressure-sensitive adhesive composition and a surface protection film capable of achieving both excellent antistatic performance and stain resistance. A pressure-sensitive adhesive composition comprising an acrylic polymer, an antistatic agent, and a crosslinking agent, wherein the acrylic polymer has a glass transition temperature of 0 ° C. or less, the crosslinking agent is a trifunctional or more isocyanate compound, and the antistatic agent is a cation and an anion 1 selected from the group consisting of a trifluoromethanesulfonate anion, a pentafluoroethanesulfonate anion, a heptafluoropropanesulfonate anion, and a nonafluorobutanesulfonate anion. It is a paper, and contains the said antistatic agent as an essential component in the ratio of 0.01-10 weight part with respect to 100 weight part of the said acrylic polymer. |
