  • Liquid electrophotographic ink
    Patent number: 9785063
    Abstract: The present disclosure discloses a liquid electrophotographic ink. The ink includes a liquid vehicle, an ethylene acid copolymer, and an ethylene/(meth)acrylic acid C1-10 alkyl ester copolymer. Also disclosed is a method for the manufacture that ink and a method for performing a liquid electrophotographic process by printing a substrate with the ink.
    Type: Grant

  • 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.

  • High NVS liquid toner
    Patent number: 8974997
    Abstract: The present disclosure is drawn to LEP toners, systems, and methods of manufacturing LEP liquid toners. Specifically, a high NVS liquid toner can comprise a ground up admixture of a hydrocarbon carrier fluid, pigment particles, and a polymer paste having an NVS content of about 38 wt % to about 65 wt %. The resultant high NVS liquid toner has an NVS content of about 28 wt % to about 38 wt % and a viscosity of about 3,000 cPs to about 25,000 cPs.
