Abstract

PURPOSE:To manufacture capsules of dense and excellent film by using a maleic anhydride copolymer as an emulsifier in the micro-capsulation of a hydrophobic liquid by an interfacial polymeization. CONSTITUTION:In the micro-capsulation using a film-forming reaction of a multivalent isocyante and a compound with active hydrogen, e.g., an amine, an alcohol, etc., a maleic anhydride copolymer as the main-component of an emulsifier is used in emulsifying a hydrophobic liquid in which a multivalent isocyanate is dissolved into water, thus resulting in the uniformity of the diameters of emulsified particles and also the production of micro capsules having dense films which are excellently suitable for the incorporation of electron donative charomogens for noncarbon papers in particular.
