Abstract
The present invention relates to a water dispersion for ink-jet printing, including a colorant, particles (A) (except for pigments) having a refractive index of 1.0 to 2.2, and a nonionic organic compound containing a saturated or unsaturated hydrocarbon group having 8 to 30 carbon atoms, and exhibiting a solubility of 1 g or less in 100 g of water as measured at 25° C., as well as a water based ink containing the water dispersion. There are provided a water-based ink for ink-jet printing which can exhibit a high optical density upon one-pass printing on plain papers and, therefore, is suitable for high-speed printing, as well as a water dispersion used in the water-based ink.
