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.
