ABSTRACT:
Microcapsules are produced by dispersing and emulsifying hydrophobic material such as water insoluble material, color forming material, color forming assistant, oil and mixture of oil and various medicines dissolved therein in gelatin aqueous solution so as to produce minute particles, adding coacervate forming agent composed of phytic acid and/or its salt to the above system to form gelatin and coacervate on the surface of minute cores of the hydrophobic material thereby forming coating film thereon into capsule form.
