Abstract

PURPOSE:To obtain the microcapsules which are not mutually fused and do not lose flowability by constituting the microcapsule from a double wall films consisting of polyvinyl and ethyl cellulose. CONSTITUTION:The wall film of the microcapsule is constituted from a double wall films consisting of the wall film of polyvinyl acetate surrounding a core substance at first and the wall film of ethyl cellulose subsequently surrounding the polyvinyl acetate wall film. Because the microcapsules having thus obtained double wall films are not mutually fused during storage and do not lose flowability, they are useful for pharmaceuticals or foods.
