The present invention relates to a process for preparing a microencapsulated pigment, which comprises adding a polymerizable surfactant having a hydrophilic group, a hydrophobic group and a polymerizable group, a polymerization initiator and an aqueous medium to a wet pigment, and conducting emulsion polymerization to encapsulate pigment particles with a polymer. Also disclosed are a microencapsulated pigment obtained by using this preparation process and an ink for ink jet recording containing at least the microencapsulated pigment and water.
本发明涉及一种制备微胶囊化颜料的方法,包括向潮湿的颜料中添加具有亲水基团、疏水基团和可聚合基团的可聚合表面活性剂、聚合引发剂和水介质,并进行乳液聚合以将颜料粒子封装在聚合物中。本发明还公开了使用该制备方法获得的微胶囊化颜料和至少包含微胶囊化颜料和水的喷墨记录墨水。
