PROBLEM TO BE SOLVED: To provide an ink composition for ink-jet printing use, having both high jetting stability and intermittent jetting stability, giving prints of improved quality, hue and weatherability and showing high drying rate of ink on printed paper, and to provide an ink-jet printing method capable of giving such high- quality prints based on both the high jetting stability and intermittently jetting stability of the ink composition. SOLUTION: This ink composition is such that a dye with a specific structure is dissolved or dispersed in an aqueous medium, including a water-miscible organic solvent as well. The other objective ink-jet printing method involves using the ink composition. |
