Abstract
Described are encapsulated pigments having an outer water-soluble shell and a core containing organic and/or inorganic pigments and optionally solvents and/or conventional additives. The encapsulated pigments have very good dissolution rates in aqueous systems and are therefore particularly suitable for paints, coatings, printing inks, in papermaking and in cosmetic formulations.
