Abstract
A water-based ink for ink-jet recording includes: a resin-dispersed pigment; an emulsion of a vinyl chloride-acrylic copolymer having a glass transition temperature of equal to or more than 50° C.; an anionic surfactant having only one anion group in a molecule thereof; and water. A ratio (S/E) of a blending amount (S) of the anionic surfactant to a solid content blending amount (E) of the emulsion of the vinyl chloride-acrylic copolymer in an entire amount of the water-based ink is equal to or more than 0.2.
