    摘要: The present disclosure is drawn to a liquid electrophotographic ink, comprising a carrier liquid, and a pigment-polymer blend composition dispersed in the carrier liquid, the pigment-polymer blend composition comprising a pigment and a polymer blend of three distinct polymers. The polymer blend can comprise a first polymer having a melt flow rate of about 20 to about 70 g/10 min and a Vicat softening point of about 60° C. to about 70° C., a second polymer having a melt flow rate of about 80 to about 120 g/10 min, and a third polymer having an acidity of about 160 to about 230 mg KOH/g and a melt flow rate of at least 500 g/10 min. The liquid electrophotographic ink is typically formulated for printing from a liquid electrophotographic printer.
