WATER-BASED INK FOR INK-JET RECORDING, INK CARTRIDGE, AND INK-JET RECORDING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a water-based ink for ink-jet recording using a pigment which suppresses propagation of microorganisms such as molds and is also excellent in the chromaticness and the storage stability without increasing the viscosity.SOLUTION: A water-based ink for ink-jet recording includes: a pigment; water; 1,2-alkanediol; a compound including an isothiazoline ring; and a surfactant represented by the general formula (1); where 1,2-alkanediol has 4-6 carbon atoms, and the content thereof is 8 wt.% or more.
