摘要：
The present invention relates to a microcapsule having a core material encapsulated with a capsule wall obtained by coagulating the fine colloidal particles by using an electrolyte, and a process for producing such microcapsules. In the present invention, inorganic and/or organic colloidal particles are used as the wall material and such particles are coagulated by using an electrolyte to form the capsule wall, so that it is possible to produce the microcapsules under mild conditions and with simple operations, and in addition, even the physically and/or chemically instable core materials can be easily encapsulated.
