Abstract

The invention relates to a coating composition suitable for the coating of a pharmaceutical or nutraceutical dosage form, comprising a core comprising one or more pharmaceutical or nutraceutical active ingredients, wherein the coating composition is comprising at least 20% by weight of an enteric core/shell polymer composition derived from an emulsion polymerization process, wherein either the core of the core/shell polymer composition is formed by a water-insoluble, not cross-linked polymer or copolymer and the shell of the core/shell polymer composition is formed by an anionic polymer or copolymer or vice versa.
