Patent

CA 2121355

A water-dispersible, inherently tacky pressure-sensitive adhesive comprising a tacky emulsion polymer formed of from about 80 % to 90 % by weight of monomers comprising a major portion of at least alkyl acrylate containing from 4 to about 8 car- bon atoms in the alkyl group and from about 20 % to 10 % by weight of a mixture of acrylic acid with at least an oleophilic unsat- urated carboxylic acid, said emulsion polymer having a glass transition temperature of -15 to -50°C and formed in the presence of anionic and nonionic surfactants. A sufficient amount of chain transfer agent is employed to provide an emulsion polymer which when coated on a repulpable paper substrate enables recovery of paper fibers substantially free of adhesive under condi- tions of TAPPI Useful Method 213 and/or 204, and resistant to loss of adhesive properties on exposure to high humidity.
