Polymer emulsion compositions for use in printing inks and printing inks made from the compositions are provided. The emulsion compositions include an aqueous continuous phase containing water and a dissolved carboxylic acid-functional support polymer. The dispersed phase of the emulsion composition contains crosslinked, dispersed polymer particles. The emulsion compositions also include at least one multivalent metal crosslinker and at least one stabilizing agent. The polymer emulsion compositions display superior printability properties in inks and other coatings formulated with them, yet are stable at elevated temperatures for long periods of time.
