Novel enteric microcapsules containing an active compound as a core material, the coating walls of which consist essentially of ethylcellulose and an enteric polymer material, and optionally a water-swellable polymer material being incorporated into the core material, and a process for the preparation thereof. The microcapsules can easily release the active compound in intestinal tract while protecting the core material sufficiently in stomach.
