ABSTRACT:
An ink composition including a colorant, a cyclic amide compound, a cyclic dicarbonyl compound, and water, an ink cartridge including the same, and an inkjet recording apparatus including the same. The ink composition maintains high solubility and stability of a colorant, even when used in small amounts, thereby enhancing not only a storage stability but also a fusing property of the ink composition on a print medium, and thus reinforces a rubbing resistance of the ink composition on the print medium. The ink composition is easily dried on the print medium, and thus bleeding between colors is minimized, thereby improving printed image quality because little or solvent having a high boiling point is used in the ink composition.
