<p><P>PROBLEM TO BE SOLVED: To provide a crosslinked core-shell polymer particle usable in a water-based ink for ink-jet printing and excellent in density of printing, in improving gloss, and in controlling bronzing phenomena, and to provide a water dispersion, a water-based ink containing the same, and a method for producing the crosslinked polymer particle. <P>SOLUTION: The crosslinked core-shell polymer particle contains a pigment, and a core portion and a shell portion of the crosslinked core-shell polymer particle are each crosslinked, and a weight ratio of the pigment and the crosslinked core-shell polymer [(weight of the pigment/weight of the pigment-containing crosslinked core-shell polymer particle)×100] is 25-75, the water dispersion and the water-based ink for ink-jet printing are prepared by using the crosslinked core-shell polymer particle, and the method for producing the crosslinked polymer particle is elucidated. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
