Abstract

Stable water-borne polymer compositions are disclosed. The compositions comprise a water-borne polymer, a metal cross-linking agent and a stabilizing agent comprising from 2 to 10 carbon atoms and at least two functional groups independently selected from hydroxy and carboxy. The stabilizing agent is present a 1.4 mole percent or more of the amount of metal cross-linking agent. Inventive compositions are particularly suitable for use in water-based inks and coatings. Methods of making and using the coating compositions are also described.
