An adhesive blend is comprised of a hydrophilic pressure sensitive adhesive comprising the polymerization product of (a) about 15 to about 85 parts by weight of an (meth)acrylate ester monomer wherein the (meth)acrylate ester monomer, when polymerized, has a glass transition temperature (T.sub.g) of less than about 10.degree. C.; (b) about 85 to about 15 parts by weight of a hydrophilic acidic comonomer; and (c) at least about 10 parts based on 100 parts of the sum of components (a)+(b) of a non-reactive plasticizing agent and a hydrophobic pressure sensitive adhesive comprising an elastomer or thermoplastic elastomer including styrene block copolymers (e.g., linear, radial, tapered, star) consisting of copolymerized styrene and isoprene, butadiene or ethylene-butylene; polyisoprene; polybutadiene; polyisobutylene; butyl rubber; styrene-butadiepe rubber; natural rubber; and poly-.alpha.-olefins (e.g., polyhexene, polyoctene and propylene-hexene).
