摘要： A coating composition for the enteric coating of capsule halves made of water-soluble or water-swellable polymer material in a dipping process is provided. The composition is an aqueous dispersion or solution, containing a polymer mixture of at least one first (meth)acrylate copolymer, which is enteric, and at least one further (meth)acrylate copolymer, which is enteric or water-insoluble, and also auxiliaries which influence the viscosity of the dispersion and the elasticity of the dried polymer film. The solids content of the dispersion or solution is more than 25% by weight and the viscosity is 150 to 1500 mPa·s and a dried film produced from the dispersion or solution has an elongation at break of at least 200%. Also provided is a capsule composed of two capsule halves coated with the dispersion or solution in a dipping process does. The enteric capsule does not dissolve in 0.1 N HCl at pH 1.2 after two hours, but completely dissolves in buffer at pH 6.8 in less than 30 minutes. A method to prepare enteric coated capsule halves is also provided.
