PURPOSE:To produce a microcapsule excellent in emulsifying capacity and wall film forming capacity. CONSTITUTION:In a method for producing a microcapsule by encapsulating a hydrophoblc core substance with a melamine/formaldehyde polycondensation resin film in the presence of an anionic polymeric electrolyte, as the anionic high molecular electrolyte, a vinyl toluenesulfonic acid/maleic anhydride copolymer A and a methylvinyl ether/maleic anhydride copolymer are used in a wt. ratio of A:B=50-90:10. |
