  • Ink composition with pigment particles having a hydrophobic surface
    Patent number: 10394153
    Abstract: Provided in one example herein is a liquid electrophotographic ink composition. The composition comprises: a carrier fluid comprising a polymer; ink particles each comprising a non-aqueous polymeric resin and pigment particles distributed in the polymeric resin; and a charge director. The pigment particles comprise a metal oxide and have a hydrophobic surface. The hydrophobic surface comprises at least one of the following: (i) nanoparticles attached to each of the pigment particles, the nanoparticles comprising at least one of an oxide, a phosphate, and a nitrate; (ii) a coating disposed over each of the pigment particles, the coating comprising at least one of an oxide, a phosphate, and a nitrate; and (iii) a coating disposed over each of the pigment particles, the coating comprising at least one of a polymer and an oligomer.

  • Liquid electrophotographic inks
    Patent number: 8980518
    Abstract: The present disclosure provides for a liquid electrophotographic (LEP) ink comprising a carrier fluid, a pigment, a high melt viscosity ethylene acrylic acid copolymer resin, and a high acid ethylene acrylic acid copolymer resin. The high acid ethylene acrylic acid copolymer resin can have an acid content of at least 15 wt % and a viscosity of at least 8,000 poise. Additionally, the LEP ink can have a total resin acidity of at least 15 wt % and a total resin melt viscosity of at least 20,000 poise.
