ABSTRACT:
A water-based pigment ink contains a pigment, a hydrophilic dispersant, an aqueous medium, an alkali agent for solubilizing the hydrophilic dispersant in the aqueous medium, and a hydrophilic compound having at least one structural unit of “hydrophobic molecular chain-hydrophilic molecular chain-hydrophobic molecular chain” in a structure thereof. The water-based pigment ink is suited especially as an ink for ink-jet printers.
