Abstract: Disclosed herein is a toner composition, developer and additive for a toner composition. The toner composition includes toner particles having at least one resin, an optional colorant, an optional wax, and a crosslinked polymer particle on at least a portion of an external surface of the toner particles. The crosslinked polymeric particle on a surface of the toner particles includes at least a hydrophobic monomer comprising a non-fluorinated monomer having a carbon to oxygen (C/O) ratio of 3 or greater or a fluorinated monomer. The crosslinked polymer particle includes a second monomer comprising two or more vinyl groups present in an amount from about 8 wt % to about 40 wt % of the copolymer, a metal oxide and optionally a charge control agent monomer.

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.

Abstract: A process for making a latex emulsion suitable for use in a toner composition includes co-emulsifying a bio-based resin with an insoluble component, such as a pigment or wax, whereby the resin encapsulates the insoluble component. The resulting latex, including the insoluble component encapsulated in the resin, may then be utilized to form a toner. The insoluble component may thus be included in toner particles, which might otherwise be difficult to achieve, using emulsion aggregation processes.
Abstract translation: 制备适用于调色剂组合物的胶乳乳液的方法包括用生物基树脂与不溶性组分如颜料或蜡共乳化，由此树脂封装不溶性组分。 然后可以将所得胶乳（包括包封在树脂中的不溶性组分）用于形成调色剂。 因此，使用乳液聚集方法可能将不溶性组分包含在可能难以实现的调色剂颗粒中。
