A process for improving a latex comprising the steps of (a) providing a latex comprising a polymer binder, wherein said polymer binder is formed by polymerization of a monomer mixture comprising one or more ethylenically unsaturated carboxylic acid functional monomer, and (b) passing said latex comprising said polymer binder over a cation exchange resin.The said latex is used in inks as polymeric binder. Procédé pour améliorer un latex comprenant les étapes consistant à (a) prendre un latex comprenant un liant polymère, ledit liant polymère étant formé par polymérisation d'un mélange de monomères comprenant un ou plusieurs monomères fonctionnels d'acide carboxylique éthyléniquement insaturés, et (b) faire passer ledit latex comprenant ledit liant polymère sur une résine d'échange de cations. Ledit latex est utilisé dans des encres en tant que liant polymère.
