<P>PROBLEM TO BE SOLVED: To provide an inkjet recording ink capable of giving recorded matter in which a picture image is prevented from blurring, even when regular paper is used in inkjet recording, capable of giving high color development to the picture image, and capable of giving a high printing density to the recorded matter, to provide an encapsulated pigment capable of preparing the ink, and to provide an aqueous dispersion. <P>SOLUTION: The encapsulated article is formed by covering a core substance of which the surface has an electric charge with a polymer which has repeating units derived from an ionic polymerizable surfactant and repeating units derived from a hydrophilic macromonomer. The method for producing the encapsulated article comprises mixing the ionic polymerizable surfactant into an aqueous dispersion in which the core substance is dispersed, then adding the hydrophilic macromonomer thereto, and further adding a polymerization initiator thereto, so as to polymerize the mixture. The aqueous dispersion contains the encapsulated article. The inkjet recording ink contains at least the encapsulated article and water. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
