  • Patent number: 7485179
    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.

  • Patent number: 7294183
    Abstract: An inkjet ink having an increased shelf life. The inkjet ink comprises an ink vehicle and a reactive colorant. The reactive colorant is nonreactive with water,thereby increasing the shelf life of the inkjet ink to greater than approximately twelve months. An inkjet printing system comprising the inkjet ink and an activating agent is also disclosed. A reactive colorant of the inkjet ink is nonreactive with water but is sufficiently reactive with the activating agent to form an activated complex to fix the reactive colorant to a textile substrate. A method of printing on a textile substrate is also disclosed.
