Abstract
The present invention relates to a water-based ink for ink-jet printing which not only satisfies a high optical density but also exhibits excellent high lighter-fastness and gloss; and a water dispersion used for the water-based ink. There are provided a water dispersion for ink-jet printing containing (A) a self-dispersible pigment, (B) self-emulsifiable polymer particles containing a constitutional unit derived from a salt-forming group-containing monomer, and (C) emulsion polymer particles; and a water-based ink containing the water dispersion.
