PURPOSE:To penetrate the specific liquid C to be incorporated into microcapsules contg. liquid A into the microcapsules by dispersing said microcapsules into the liquid B having no compatibility with the liquid A and adding the liquid C to the liquid B. CONSTITUTION:Water is incorporated into microcapsules prepared by an interfacial polymn. method or the like, and further the microcapsules are dispersed into benzene or the like having no compatibility with water. The liquid to be incorporated into the microcapsules is added into the benzene. Sulfonic acids, amines, inorg. acids and phosphorus compds. of which the solubility in water is at least two times of solubility in benzene and the solubility in water is at least 10g/100g solvent are acceptable for the liquid. Such liquid is penetrated in the microcapsules, whereafter the microcapsules are removed from the benzene liquid, and the microcapsules contg. the above-mentioned sulfonic acids, etc. are obtd. |
