Patent ID: 6855386

Claim:
A hot melt pressure sensitive adhesive comprising a pressure sensitive adhesive having a flow temperature and a thermoplastic packaging material enveloping said wet stick pressure sensitive adhesive, said thermoplastic packaging material having a melting temperature lower than the flow temperature of the pressure sensitive adhesive, wherein said pressure sensitive adhesive comprises the polymerization product of: (a) about 30 to about 70 parts by weight of an (meth)acrylate ester monomer wherein the (meth)acrylate ester monomer, when homopolymerized, has a Tg of less than about 10° C.; (b) about 70 to about 30 parts by weight of a hydrophilic acidic comonomer; and (c) about 10 to 100 parts based on 100 parts (a)+(b) of a non-reactive plasticizing agent, wherein the pressure sensitive adhesive adheres to wet substrate surfaces.
