ABSTRACT:
A water-based ink for inkjet printing comprising a water dispersion of vinyl polymer particles prepared by containing a pigment in a vinyl polymer prepared by copolymerizing a monomer mixture comprising (a) a salt-forming group-containing monomer, (b) a macromer, and (c) a monomer copolymerizable with the salt-forming group-containing monomer and the macromer; and a process for preparing a water-based ink for inkjet printing comprising a water dispersion of vinyl polymer particles prepared by containing a pigment in a vinyl polymer, comprising dissolving in an organic solvent a vinyl polymer prepared by copolymerizing a monomer mixture comprising (a) a salt-forming group-containing monomer, (b) a macromer, and (c) a monomer copolymerizable with the salt-forming group-containing monomer and the macromer; adding a pigment to the resulting solution; pre-kneading the mixture; thereafter adding a neutralizing agent and water and kneading the mixture, to give an oil-in-water dispersion; and distilling off the organic solvent from the resulting kneaded product.
