Abstract: Disclosed herein is a toner composition, developer and additive for a toner composition. The toner composition includes toner particles including at least one resin, an optional colorant, an optional wax, and a polymeric toner additive on at least a portion of an external surface of the toner particles. The polymeric toner additive includes a polymeric resin including a fluorinated monomer, wherein the polymeric resin is less than 10% by weight crosslinked, and optionally a charge control agent comprising nitrogen containing group at 0.1 wt % to 1.5 wt % of the polymeric resin.

Abstract: Compositions are provided which may comprise a plurality of organic additive particles, the particles comprising a polymerization product of reactants comprising a dioxane/dioxolane monomer and a vinyl co-monomer, wherein the dioxane/dioxolane monomer is an ester of (meth)acrylic acid with an alcohol comprising a dioxane moiety, an ester of (meth)acrylic acid with an alcohol comprising a dioxolane moiety, or both. Toner and additive manufacturing compositions comprising the organic additive particles are also provided.

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.
