摘要：PURPOSE:To obtain a cimcrocapsule having a dense wall film, free from coagulation and rich in flowability, in preparing the microcapsule due to the phase separation of ethyl cellulose, by using a certain kind of an org. solvent as a coagulation preventing agent. CONSTITUTION:In preparing a microcapsule by forming a ethyl cellulose wall film on a core substance by the phase separation of ethyl cellulose, as a coagulation preventing agent in the phase separation of ethyl cellulose, an org. solvent of which the hydrogen bonding component deltah of a dissolving parameter is 3.5- 11.0 [(Cal/cm<2>)1/2] and which is dissolved or partially dissolved in cyclohexane, for example, mathanol or ethanol is used. By this method, a microcapsule having a dense wall film, free from coagulation and rich in flowability can be prepared.
