    Abstract: Disclosed herein is a toner composition, developer and additive for a toner composition. The toner composition includes toner particles comprising 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 comprising a cross-linked fluorinated acrylic monomer, a cross-linkable monomer containing two or more vinyl groups at 8 wt% to 40 wt% of the polymeric resin, and optionally a charge control agent comprising nitrogen containing group at 0.1 wt% to 1.5 wt% of the polymeric resin.

    Abstract: Additive manufacturing processes featuring consolidation of thermoplastic particulates may form printed objects in a range of shapes. Inorganic nanoparticles disposed upon the outer surface of the thermoplastic particulates may improve flow performance of the thermoplastic particulates during additive manufacturing, but may be undesirable to incorporate in some printed objects. Polymer nanoparticles may be substituted for inorganic nanoparticles in some instances to address this difficulty and provide other advantages. Particulate compositions suitable for additive manufacturing may comprise: a plurality of thermoplastic particulates comprising a thermoplastic polymer and a plurality of polymer nanoparticles disposed upon an outer surface of the thermoplastic particulates, the polymer nanoparticles comprising a crosslinked fluorinated polymer.
