Abstract: A light-cyan radiation-curable gel ink including at least one curable monomer, at least one organic gellant, at least one photoinitiator, and a colorant. The colorant includes a cyan colorant, a hue-adjusting colorant that absorbs light having a wavelength of from about 500 to about 600 nm, and an optional shade- adjusting colorant that absorbs light having a wavelength of from about 400 to about 500 nm.

Abstract: Disclosed are amorphous polyesters that contain only renewable resources designed for emulsion aggregation toner fabrication. The amorphous polyesters may be obtained from the mixture of three different monomers: 1,4:3,6-dianhydro-D-sorbitol (isosorbide), nonanedioic acid (azelaic acid), and butanedioic acid (succinic acid). Different polymer properties may be achieved depending on the ratio of these three monomers. By altering the ratio, polymers of high to low acid value can be obtained, as well as different ranges of glass transition temperatures.

Abstract: Curable solid inks which are solid at room temperature and molten at an elevated temperature at which the molten ink is applied to a substrate. In particular, the curable solid inks of the present embodiments retain the advantages of handling, safety, and print quality usually associated with conventional curable solid phase change inks but have replaced the petroleum-based materials generally used in the conventional inks with renewable "green" materials to provide a robust and environmentally-friendly curable solid ink.

Abstract: A process for making a latex emulsion suitable for use in a toner composition includes contacting at least one crystalline polyester resin with an organic solvent and a stabilizing agent to form a resin mixture, adding a neutralizing agent, and deionized water to the resin mixture, removing the solvent from the formed latex, and continuously recovering latex particles.
