Abstract:
1. Acrylic pressure sensitive adhesive composition comprising: a) 100 part by weight of acrylic copolymers; b) 0.01 to 20 part by weight of ester plasticizer having at least one ether linkage in the molecular structure represented by the following formula (1): wherein, R c) 0.01 to 12 part by weight of metal salts consisting of alkali metal cation, and anion which is counter-ion of super strong acid and has perfluoro alkyl group represented by the following formula (2): wherein, the metal salts have one or more anions selected from the group consisting of bistrifluoromethanesulfoneimide, bispentafluoroethanesulfoneimide, and bisperfluorobutanesulfoneimide, and one or more cations selected from the group consisting of lithium, sodium, and potassium, wherein the ester plasticizer having at least one ether linkage forms a complex with the metal salts.
