US 12,686,797 B2 · Acrylic-based adhesive composition with ethylene-based polymer

Abstract

The present disclosure is directed to a water-based pressure-sensitive adhesive composition. In an embodiment, the water-based pressure-sensitive adhesive composition includes (A) an acrylic dispersion composed of particles of (i) an acrylic-based polymer with a glass transition temperature (Tg) less than −20° C., and (ii) a surfactant. The water-based pressure-sensitive adhesive composition also includes (B) an ethylene-based polymer dispersion comprising an ethylene and vinyl acetate copolymer and an ethylene acid copolymer. Further disclosed are articles with the water-based pressure-sensitive adhesive composition.
