PURPOSE:To enhance the isolation capacity of a component at room temp. and mass permeability under heating by reacting a compound represented by a predetermined chemical formula with a component selected from water, polyvalent amine and polyhydric alcohol to form a microcapsule. CONSTITUTION:A compound represented by formula I (wherein Ar1, Ar2 and Ar3 may be same or different and are respectively an arylene group such as phenylene or naphthylene and may have a substituent such as an alkyl group, an alkyloxy group or a halogen atom) is dissolved in a hydrophobic liquid such as kerosene or paraffin and the resulting solution is emulsified within an aqueous solution containing an emulsifier to form fine liquid droplets. Next, a synthetic film of polyurethane and/or polyurea is formed to an oil-water interface. |
