    Abstract: Disclosed is a phase change ink comprising (a) a colorant and (b) a phase change ink carrier, said carrier comprising (i) a branched triamide and (ii) a polyethylene wax having an average peak molecular weight of from about 350 to about 730, a polydispersity of from about 1.03 to about 3.0, and an asymmetrical molecular weight distribution skewed toward the high molecular weight end. Also disclosed is a process which comprises (1) incorporating into an ink jet printing apparatus a phase change ink comprising (a) a colorant and (b) a phase change ink carrier, said carrier comprising (i) a branched triamide and (ii) a polyethylene wax having an average peak molecular weight of from about 350 to about 730, a polydispersity of from about 1.03 to about 3.0, and an asymmetrical molecular weight distribution skewed toward the high molecular weight end; (2) melting the ink; and (3) causing droplets of the melted ink to be ejected in an imagewise pattern onto a substrate.

    Abstract: Disclosed is an electrophotographic liquid developer composition comprising a liquid medium, first toner particles charged to one polarity and comprising a resin and a first pigment, second toner particles charged to a polarity opposite to that of the first toner particles and comprising a resin and a second pigment of a color different from that of the first pigment, and a charge director. The disclosed developer is suitable for developing electrostatic latent images in two different colors in a single development step. The latent image comprises three areas of charge; toner particles of one color are selectively attracted to one area, toner particles of the other color are selectively attracted to the second area, and the third area remains undeveloped as a background area.

    Abstract: Disclosed is an electrophotographic liquid developer composition comprising a liquid medium, first toner particles charged to one polarity and comprising a first dye and polymeric cores to which steric stabilizer polymers have been attached, second toner particles charged to a polarity opposite to that of the first toner particles and comprising a second dye of a different color than the first dye and polymeric cores to which steric stabilizer polymers have been attached, and a charge director. The disclosed developer is suitable for developing electrostatic latent images in two different colors in a single development step. The latent image comprises three areas of charge, toner particles of one color are selectively attracted to one area, toner particles of the other color are selectively attracted to the second area, and the third area remains undeveloped as a background area.
