<P>PROBLEM TO BE SOLVED: To provide a micro-capsulate material capable of highly exhibiting various functions in various industrial and technical fields and a method for producing the micro-capsulate material. <P>SOLUTION: A core material having an electric charge on the surface is covered with a first covering layer comprising a polymer, which has at the least a repeating structural unit (1) derived from an ionic polymerizable surfactant having the electric charge different from that of core material surface and/or an ionic monomer and another repeating structural unit (2) derived from another ionic polymerizable surfactant having the electric charge similar to or different from that of the core material surface, and covered with a second and succeeding covering layers each comprising the polymer having the above repeating structural units. These covering layers are formed by repeating a step of adding the polymer having the above repeating structural units to an aqueous dispersion of the core material having an ionic group on the surface, emulsifying the polymer-added dispersion and adding a polymerization initiator to the emulsified dispersion to initiate emulsion polymerization. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
