The present invention provides a pressure-sensitive adhesive composition and a surface protective film capable of achieving both excellent antistatic performance and stain resistance. An adhesive composition containing an acrylic polymer, an antistatic agent and a crosslinking agent, wherein the acrylic polymer has a glass transition temperature of 0 ° C. or lower, the crosslinking agent is a trifunctional or higher isocyanate compound, and the antistatic agent is a cation and an anion. It is an ionic compound with a melting point of 25 ° C. or higher, wherein the anion is selected from the group consisting of trifluoromethanesulfonate anion, pentafluoroethanesulfonate anion, heptafluoropropanesulfonate anion, and nonafluorobutanesulfonate anion. It consists of paper and contains 100 weight part of said acrylic polymers as an essential component in the ratio of 0.01-10 weight part. |
