Patent ID: 7943714

Claim:
An adhesive system for fastening a non-paper polymeric label or metal foil to a surface, said adhesive system comprising: a) a film from at least two polymer fractions comprising a1) at least 5 wt. % of a hydrophilic polymer characterized as being an addition polymer that is a water soluble hydrophilic polymer and a2) at least 50 wt. % of a less hydrophilic polymer being characterized as an addition polymer having a glass transition temperature from about 10° C. to about 50° C. that is not water soluble and b) a water-based activation solution, wherein said film and activation solution are characterized by the conversion of said film from a non-tacky state to a tacky state in less than one second upon contact with said water-based activation solution wherein said less hydrophilic polymer is a copolymer comprising repeat units 10-85 wt. % of repeat units derived from C 1 -C 15 alkyl esters of (meth)acrylic acid monomer and 5-40 wt. % of repeat units from polar monomer containing carboxylic, sulfonic, sulfate, phosphate, and/or phosphonic acids groups and/or their salts.
