Abstract:
The present disclosure provides a polyester toner resin comprising a polyhydroxylated thymol derivative that may be used in manufacturing an emulsion aggregation (EA) toner for imaging devices.
Abstract:
Methods for making toner particles comprising a polyester-wax resin, wherein the polyester-wax resin includes a bio-based oil that is chemically incorporated into the main chain of the polyester resin. The toner particles may be formed using emulsion aggregation methods. A toner formed from the toner particles may be used in low-oil or oil-less fusing systems.
Abstract:
Environmentally friendly toner particles are provided which may include a bio-based amorphous polyester resin including camphoric acid, optionally in combination with a crystalline resin. Methods for providing these toners are also provided.
Abstract:
A light-cyan solid ink including an ink vehicle 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:
Environmentally friendly resin particles are provided which include a monomer having a color, which is able to impart color to the resulting resin. The resulting resin may be used to form various articles, including toner. A toner of the present disclosure may thus include the bio-based polyester resin, optionally in combination with another amorphous resin and/or a crystalline resin. Methods for providing these resins are also provided.
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.
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:
Pigment particles with at least one metal oxide surface additive, wherein the at least one metal oxide surface additive is a metal oxide particle covalently bonded with at least one polycondensation polymer, wherein the pigment particle is a pearlescent or metallic pigment.
Abstract:
A light-magenta solid ink including an ink vehicle and a colorant. The colorant includes a magenta colorant, a hue-adjusting colorant that absorbs light having a wavelength of from about 400 to about 500 nm, and an optional shade-adjusting colorant that absorbs light having a wavelength of from about 600 to about 700 nm.
Abstract:
Toners made by the emulsion aggregation process comprising an amorphous resin and a nucleated crystalline resin. Such toners demonstrate improved charging performance in the A-zone and the C-zone, improved heat cohesion and improved resistivity.
