<P>PROBLEM TO BE SOLVED: To provide an inkjet recording water-based ink excellent in the control of glossiness and a bronzing phenomenon, an aqueous dispersion which is used as the ink, and a method for preparing crosslinked core-shell particles. <P>SOLUTION: The inkjet recording aqueous dispersion (1) comprises water insoluble crosslinked particles containing a colorant and core-shell polymer particles or crosslinked polymer particles. The water-based ink (2) comprises the dispersion, and the method for preparing the crosslinked core-shell polymer particles (3) comprises polymerizing an emulsion composition comprising a water insoluble polymer, a crosslinkable monomer having at least two reactive unsaturated groups in the molecule, and a hydrophobic monomer, to prepare a dispersion of core-shell polymer particles whose core portion is crosslinked, and thereafter reacting the polymer particles with a crosslinking agent having at least two reactive functional groups in the molecule. <P>COPYRIGHT: (C)2008,JPO&INPIT |
