摘要:
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.

The present disclosure is drawn to a liquid toner composition comprising: (a) a carrier liquid; (b) particles comprising (i) a first component comprising a polymer having acidic side groups; and (ii) a second component comprising a polymer having ester side groups; and (c) a charge director. Also described herein are a method of producing a liquid toner composition and a method of electrophotographic printing using a liquid toner composition.
摘要:
The present invention relates to a liquid electrophotographic ink comprising a carrier liquid, a pigmented resin composite dispersed in the carrier liquid, and about 0.15 to about 10% (w/w) of an organic wax. The liquid electrophotographic ink is typically formulated for printing in a liquid electrophotographic printer.

摘要:
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.
