Abstract: A process for making a self-emulsifying composite suitable for use in forming latex emulsions includes contacting a resin with a solid or highly concentrated surfactant, a solid neutralizing agent in the absence of water and an organic solvent to form a mixture, melt mixing the mixture, and forming a self-emulsifying composite of the melt mixed mixture such as a granule. Self-emulsifying granules are also provided and configured to form a latex emulsion when added to water, which may then be utilized to form a toner.

Abstract: Emulsion aggregation toner particles including a resin, polysaccharide particles, an optional wax, and an optional colorant. The toner particles contain about 1 to about 50 wt % polysaccharide particles based on the total weight of the toner particles.

Abstract: Toners are provided, which possess low melt properties capable of producing a low gloss finish. The toners include a core and a shell. The shell includes a crystalline resin. The core may include at least one amorphous resin, an optional crystalline resin, an optional wax, and an optional colorant.

Abstract: According to aspects of the embodiments there is provided a cassette cleaning web having an agent metering tube that can apply oil via a drip pipe to a web as it enters a nip within the fusing surface. Dispensing the oil as it enters the nip increases the transportation and the holding capacity of the web. The cassette cleaning web can reduce the oil-on-copy to less than 3 mg/copy and more specifically to less than 1 mg/copy which would allow for adequate post finishing applications while still using amino functionalized fuser oil in the fuser subsystem. The cassette cleaning web reduces the contamination of the oil-sump because used web materials are wound up and oil or contaminate materials like wax, toner are retained in the spent web cartridge. This invention enables reduced oil-on-copy, eliminates the bulky and expensive release agent management system, and also provides a direct cleaning to the surface of the fuser roll.

Abstract: Exemplary embodiments provide an erasable medium having an overcoat layer on a photochromic layer to provide a non-adhesive surface for the erasable medium when exposed to high temperatures, wherein the overcoat layer can include a latex or a mixture of a latex and a wax.

Abstract: The present disclosure provides toners and processes for making said toners. In embodiments, the toners are invisible when viewed under natural light, but possess a fluorescent agent that renders them visible when exposed to UV light of a specific wavelength. In other embodiments the toners have a color under natural light, and a different color when exposed to UV light.

Abstract: The present disclosure provides toners and processes for making said toners. In embodiments, the toners are invisible when viewed under natural light, but possess a UV emitter that renders them visible when exposed to UV light of a specific wavelength. By selecting the appropriate UV emitter and utilizing an ionic crosslinker, the gloss of the toner may be tailored to match the gloss of any substrate, such as paper, to which the toner is to be applied, thereby further enhancing its invisibility under visible light.

Abstract: A process for making a resin emulsion suitable for use in forming toner particles including an oil component incorporated into the latex core of the toner particles.

Abstract: The present disclosure provides for enzymatic polymerization to produce polyester resins suitable for use in manufacturing toners. In embodiments, crystalline copolymers, which are polyesters, may be synthesized from lactones, cyclic anhydrides, cyclic carbonates, and combinations thereof. These crystalline copolymers, in turn, may be utilized in the synthesis of toner particles.

Abstract: An emulsion aggregation toner composition includes toner particles including: an unsaturated polymeric resin, such as amorphous resins, crystalline resins, and combinations thereof; an optional colorant; an optional wax; an optional coagulant; and an IR absorber. The use of an IR absorber may permit formation of color toners that have uniform gloss and crease properties, i.e., the IR absorbers may prevent gloss and crease differences between color and black toners.
