PROBLEM TO BE SOLVED: To provide a water-based pigment inkjet-recording ink composition, stably usable for a long term, by making the high concentration inkjet-recording ink, hardly causing nozzle clogging or easily recoverable when nozzle temporal clogging is caused, which ink composition has proper print density and concealing property to the corrugated board surface and, concretely, is adjusted to have ≥15 wt.% solid ingredients.SOLUTION: There is provided an inkjet-printing ink composition, provided by compounding a water-based emulsion resin having ≥16°C glass transition point and ≥10 mgKOH/g acid value, and a pigment with a water-based dispersion medium, to have ≥15 wt.% solid content based on the water-based dispersion medium, and compounding an amino alcohol as the dispersion stabilizer with the dispersion. |
