Herein is described a liquid electrophotographic ink composition including a carrier liquid and a resin including an acid copolymer and an acrylate copolymer, wherein the acrylate copolymer includes at least about 30 wt. % of the alkyl (meth)acrylate monomer.

Liquid electrophotographic ink composition

The present invention provides an electrostatic ink composition comprising a carrier liquid, a resin, a pigment and a conductive polymer. Method for producing the electrostatic ink composition and methods for printing the composition are also disclosed.

Electrostatic ink composition

The present disclosure provides for liquid electrophotographic inks having charge stabilizers and associated methods. In one example, a liquid electrophotographic ink can comprise a carrier liquid, a resin, a pigment, a negative charge director, and a charge stabilizer having a reduction potential of 0.16 v to 3.0 v.
