PCT No. PCT/US92/08760 Sec. 371 Date Apr. 14, 1994 Sec. 102(e) Date Apr. 14, 1994 PCT Filed Oct. 14, 1992 PCT Pub. No. WO93/08239 PCT Pub. Date Apr. 29, 1993.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 carbon atoms in the alkyl group and from about 20% to 10% by weight of a mixture of acrylic acid with at least an oleophilic unsaturated carboxylic acid, said emulsion polymer formed in the presence of anionic and nonionic surfactants to provide a polymer having a glass transition temperature of -15 DEG to -50 DEG C. 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 conditions of TAPPI Useful Method 213 and/or 204, and resistant to loss of adhesive properties on exposure to high humidity. |
