  • Positively charged ink composition
    Patent number: 8927635
    Abstract: Positively charged ink compositions, its use and method of making the same are disclosed. A disclosed example of the positively charged ink compositions includes a combination of a carrier liquid, basic pigment-loaded resin particles, a charge director and an acidic charge adjuvant.
    Type: Grant
    Filed: March 9, 2010
    Date of Patent: January 6, 2015
    Assignee: Hewlett-Packard Indigo B.V.
    Inventors: Yaron Grinwald, Gil Bar-Haim, Yigal Berson
  • Electronic inks and displays and image displaying methods
    Patent number: 8605352
    Abstract: An electronic ink containing charged particles includes a combination of resin particles, a pigment, and a charge director. The resin particles exhibit an average particle size less than 1.0 micron and contain a resin that exhibits a molecular weight of 500 to 20,000. The pigment is loaded on the resin particles. The charge director can physically associate with the resin particles. The charged particles may be negative or positive.
    Type: Grant

  • INK COMPOSITION
    Publication number: 20120107579
    Abstract: An ink composition having a viscosity which is below about 50.0 cps and having, at least, 10 wt %, by total weight of ink composition, of non volatile substances. Said composition comprising a carrier liquid, a dispersing agent, and solid particles; said solid particles are dispersed in the carrier liquid and comprise pigments embedded with resin polymers.
