<P>PROBLEM TO BE SOLVED: To provide an encapsulated material having various functions, which was not solved by conventional technology, and an ink composition and coating composition satisfying all of fluorescent light-emitting characteristic of a printed matter, light fastness, friction resistance, preservation stability of the ink and the recovering property of clogging of inkjet nozzles, and also capable of improving the close adhesion of an image. <P>SOLUTION: This encapsulated material containing a fluorescent pigment having an electric charge on its surface as a core substance is provided with that the core substance is covered with a wall material consisting mainly of a polymer and the polymer consists of at least (1) a recurring structural unit derived from an ionically polymerizable surfactant A and/or an ionic monomer, and (2) a recurring unit derived from an ionically polymerizable surfactant B having the same kind or opposing electric charge to that of the surface of the core material. <P>COPYRIGHT: (C)2007,JPO&INPIT |
