Abstract: Disclosed is an electrophotographic liquid developer composition comprising a liquid medium, first toner particles able to be charged to one polarity and comprising a first dye and polymeric cores to which steric stabilizer polymers have been attached, second toner particles able to be charged to a polarity opposite to that of the first toner particles and comprising a second dye of a different color from that of 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.

Abstract: A low melt toner resin with low minimum fix temperature and wide fusing latitude contains a linear portion and a cross-linked portion containing high density cross-linked microgel particles, but substantially no low density cross-linked polymer. The resin may be formed by reactive melt mixing.

Abstract: PROBLEM TO BE SOLVED: To provide ink compositions that are compatible with dampening fluids and are useful for variable data lithographic printing creating negative latent image of the ink image that is desired to be printed on the receiving substrate by evaporating the dampening fluids along the image.SOLUTION: An ink composition comprises a colorant and a plurality of curable compounds. The curable compounds have a Hansen fractional dispersion force parameter of from about 0.4 to about 0.62, a Hansen fractional polar parameter of from about 0.1 to about 0.3, and a Hansen fractional hydrogen bonding parameter of from about 0.2 to about 0.4.
