PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive composition showing an excellent balance in adhesive force at a low peeling speed and a high peeling speed, and having excellent durability performance and reworking performance.SOLUTION: The pressure-sensitive adhesive composition comprises an acrylic polymer that is a copolymer comprising (A) a (meth)acrylate monomer having 4 to 18 carbon atoms in an alkyl group, (B) a copolymerizable monomer containing a hydroxyl group, (C) a copolymerizable monomer containing a carboxyl group, (D) a polyalkylene glycol mono(meth)acrylate monomer, and (E) at least one of a nitrogen-containing vinyl monomer containing no hydroxyl group and an alkoxy group-containing alkyl (meth)acrylate monomer, and the composition further contains (F) an isocyanate compound having three or more functional groups, (G) a crosslinking retarder, and (H) a crosslinking catalyst. In the composition, the acrylic polymer has an acid value of 0.01 to 8.0. |
