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 acid dispersion composed of (i) particles of an ethylene acid copolymer having from 3 wt % to less than 50 wt % acid comonomer and a melt index from 1 g/10 min to 100 g/10 min, and (ii) at least one of a dispersant or a neutralizing agent. Further disclosed are articles with the water-based pressure-sensitive adhesive composition.
