Abstract: Ein Verfahren zum Herstellen einer Latexemulsion, die sich zur Verwendung in einer Tonerzusammensetzung eignet, schließt das Coemulgieren eines Harzes auf biologischer Basis mit einer unlöslichen Komponente, wie etwa ein Pigment oder Wachs, ein, wodurch das Wachs die unlösliche Komponente einkapselt. Der resultierende Latex, der die in dem Harz eingekapselte unlösliche Komponente einschließt, kann dann zum Bilden eines Toners verwendet werden. Die unlösliche Komponente kann somit in Tonerteilchen eingeschlossen werden, was andernfalls unter Verwendung von Emulsionsaggregationsverfahren schwierig zu erreichen sein könnte.

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: A toner having an amorphous resin, a crystalline resin, and a colorant, wherein the crystalline resin has a melting temperature of at least 70°C and a recrystallization point of at least 47°C exhibits improved document offset properties and improved heat cohesion. Annealing the toner further improves the heat cohesion and morphology of the toner.

Abstract: A method of making particles suitable for use as toners includes forming a mixture of sulfonated polyester resin, a colorant dispersion and optionally a wax dispersion, homogenizing the mixture, adding a coagulant to the mixture to aggregate the mixture to form aggregated particles, and coalescing the aggregated particles to form coalesced particles. In the method, when a predetermined average particle size is achieved during the aggregation and/or coalescing step, a complexing agent that complexes with ions of the coagulant is added in an amount effective to substantially halt any further particle growth. The complexing agent is believed to halt further growth by complexing with free coagulant ions still in the solution.

Abstract: A toner composition including an amorphous polyester resin; a crystalline polyester resin; a styrene acrylate copolymer; an optional wax; and an optional colorant; wherein the amorphous polyester resin comprises a rosin monomer content of from about 10 to about 25 percent rosin monomer based upon the total amount of monomer comprising the amorphous polyester resin. A toner composition including a core and at least one shell disposed thereover. A toner process including contacting an amorphous polyester resin; a crystalline polyester resin; a styrene acrylate copolymer; an optional wax; an optional colorant; and an optional aggregating agent; wherein the amorphous polyester resin comprises a rosin monomer content of from about 10 to about 25 percent rosin monomer heating to form aggregated toner particles; optionally, adding a shell resin to the aggregated toner particles, heating to coalesce the particles; and recovering the toner particles.

Abstract: Emulsion aggregate toner compositions that use two different emulsion aggregation (EA) technologies are described. Namely, there is provided an emulsion aggregation toner that comprises a base resin composed of both styrene-acrylate and polyester resins. Such hybrid emulsion aggregation toner compositions are lower in cost but still maintain desirable developer properties like low minimum fusing temperature (MFT) and lower dielectric loss.

Abstract: Disclosed herein is a method for manufacturing a fluorinated structured organic film (FSOF) composition for a photoreceptor. The method includes combining a fluorinated diol, an electroactive segment and a solvent in a round bottom reactor. The reacted is heated, without mixing dissolve the fluorinated diol composition. The dissolved fluorinated diol composition is mixed to dissolve the electroactive segment while maintaining the reactor at a temperature of between 80 and 85 °C. A catalyst and a leveling agent are added to the solution to initiate a pre-cure reaction. The pre-cure reaction proceeds for at least 2 hours at a temperature of between 80 and 85 °C. The solution is cooled to room temperature and filtered.
