PURPOSE: Provided is a one-component type solvent pressure solvent adhesive containing a crosslinking component for improving the storage stability by controlling the amount of a cyclic ether group and a carboxyl group, thee amount of an additive, a solid content of the adhesive and a molecular weight of the adhesive, thereby improving cohesion when being formed in a pressure sensitive adhesive sheet. CONSTITUTION: The pressure sensitive adhesive composition comprises an acrylic polymer having a weight average molecular weight of at least 300,000 and produced by copolymerizing a C1-14 alkyl methacrylate, 0.2 to 1.8 phr of an ethylenic monomer having a cyclic ether group, and 4 to 8 phr of a polymerizable unsaturated carboxylic acid.
