A method of increasing the tack of a pressure sensitive adhesive by exposing a polymeric pressure sensitive adhesive to an activating treatment, activatable articles containing such an adhesive and adhesive compositions resulting from such an activating treatment. The activatable, polymeric, pressure sensitive adhesive is preferably a water based adhesive prepared by free radical polymerization of acrylic acid, methacrylic acid, acrylate, or methacrylate monomers having from 1 to about 12 carbon atoms. The activating treatment is preferably corona charging or corona charging in combination with uv light. |
