A pressure sensitive adhesive composition is provided that includes a pressure sensitive adhesive polymer. The polymer includes: at least one copolymerized monoethylenically unsaturated (meth)acrylic acid ester monomer, wherein the (meth)acrylic acid ester monomer, when homopolymerized, has a Tg of less than about 25° C.; at least one copolymerized monoethylenically unsaturated reinforcing monomer, wherein the reinforcing monomer, when homopolymerized, has a Tg of at least about 25° C.; covalently bonded quarternary ammonium functionality; and, optionally, at least one copolymerized monoethylenically unsaturated poly(alkylene oxide) monomer. The composition optionally further includes at least one nonreactive poly(alkylene oxide) polymer and/or at least one antimicrobial agent.
