  • Patent number: 9096781
    Abstract: An aim of the prevention invention is to provide a water dispersion type acryl-based pressure-sensitive adhesive composition for re-peeling, which can prevent electrification of an adherend at the time of peeling (peeling antistatic properties) and which can form a pressure-sensitive adhesive layer excellent in adherability and re-peelable properties, and also to provide a pressure-sensitive adhesive sheet having a pressure-sensitive adhesive layer formed of the pressure-sensitive adhesive composition. 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 and a carboxyl-containing unsaturated monomer as raw material monomers, a perfluoroalkyl-containing oligomer, and an ionic compound.
