  • Water-dispersible pressure-sensitive adhesive and tape made therewith
    Patent number: 4413080
    Abstract: Water-dispersible pressure-sensitive adhesive useful for splicing carbonless paper without deactivating its color-generating system. Certain acrylate:acrylic acid copolymers are blended with acidic rosin or rosin derivative, partially neutralized with KOH in combination with NaOH and/or LiOH, and plasticized with an oily water-soluble polyoxyethylene compound. Repulpable splicing tapes can be made with the adhesive.
