Waterborne adhesive composition

Abstract

The present invention is directed to a waterborne dispersion for use in an adhesive composition, wherein the dispersion comprises dispersed polymer particles comprising both (i) a polyurethane and (ii) a vinyl polymer, wherein said dispersed particles comprising the polyurethane and the vinyl polymer in a weight ratio of the polyurethane to the vinyl polymer higher than 1, and the polyurethane-vinyl polymer comprises a crystalline phase having a melting temperature in the range from 30 to 80 °C and an enthalpy of fusion of at least 15 J / g, whereby the melting temperature and the enthalpy of fusion are determined by differential scanning calorimetry according to DIN EN ISO 11357-1:2017 (2017-02) at a heating rate of 20 K / min.
