  • Patent number: 9051485
    Abstract: Provided is an inkjet ink which can form high-quality images with high abrasion resistance and adhesiveness on a non-absorptive recording medium and which exhibits high ejection properties and excellent storage stability. Also provided is an inkjet recording method. An inkjet ink which comprises water, a pigment, a water-soluble resin, a water-soluble or Panic solvent and a surfactant, characterized in that: the water-soluble resin comprises a water-soluble resin consisting of a copolymer resin which has an acid value of 50 to 130 mgKOH/g, a glass transition temperature (Tg) of 30 to 100° C.

  • Patent number: 8889764
    Abstract: A water-based ink for inkjet recording is provided with color material, binder resin, surfactant, and water-based solvent, wherein when the ink is heated, 1) a viscosity of the ink is more than 10 mPa·s and 30 mPa·s or less, the viscosity being measured over the ink weight change rate range of 0% to 10%; 2) a viscosity of the ink is 200 mPa·s at any one of the ink weight change rate within 35% or more and 55% or less, the viscosity being measured by the E-type viscometer at 25° C. and 1 rpm; and 3) a surface tension at 25° C. of the ink at the ink weight change rate of 5% is lower than a surface tension at 25° C. of the ink at the ink weight change rate of 0%.

  • Patent number: 7726801
    Abstract: A method for ink-jet textile printing including the steps of: (a) ejecting a pigment ink from a recording head onto a fabric, wherein the pigment ink contains at least water, a pigment and a polymer, wherein the polymer has a plurality of said chains in a hydrophilic main chain and is capable of cross-linking between the side chains by irradiation of active energy rays, and (b) forming an image by irradiation of active energy rays onto the ink ejected areas.
