ABSTRACT:
Aqueous-based adhesive compositions having good adhesion to a non-polar polymeric surface and to cellulosic materials comprise a dispersion of an adhesive comprising an N-vinyl lactam polymeric resin, a tackifier for such adhesive, and an effective amount of an ethylene/vinyl acetate copolymer emulsion stabilizer for the resin and tackifier. Preferred N-vinyl lactam polymeric resins are vinyl pyrrolidone/vinyl acetate copolymers and a preferred class of tackifier are the rosin ester tackifiers.
