Abstract: An aim of the prevention invention is to provide a re-peelable water dispersion type acryl-based pressure-sensitive adhesive composition, which can prevent electrification at the time of peeling off under low humidity environments (an antistatic property for peeling off in low humidity) independently of an adherend and which can form a pressure-sensitive adhesive layer excellent in adherability and re-peelable properties. The re-peelable water dispersion type acryl-based pressure-sensitive adhesive composition of the present invention contains an acrylic emulsion-based polymer composed of a (meth)acrylic acid alkyl ester in an amount of 70 to 99.5% by weight and a carboxyl-containing unsaturated monomer in an amount of 0.5 to 10% by weight as raw material monomers, a crosslinking agent, and an ionic compound, wherein the acrylic emulsion-based polymer has an average particle diameter of 130 to 550 nm.
