PROBLEM TO BE SOLVED: To provide a water-born ink for ink-jetting that has high storage stability with no change in ink jetting even after long-term storage and gives images of high water resistance in which the water-born ink comprises hydrophobic dyes microcapsulated in a hydrophilic resin as a coloring agent or comprises the combination of the microcapsulated dyes with pigments. SOLUTION: The objective water-born ink for ink-jetting comprises at least hydrophobic dyes encapsulated in hydrophilic resin, aqueous organic substances and water and the absolute value of ζ-potential is >=30 mV. In another embodiment, the objective water-born ink for ink-jetting comprises at least the hydrophobic dyes encapsulated in hydrophilic resin, pigments, aqueous organic substances and water and the absolute value of ζ-potential is >=30 mV. |
