摘要: 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.

摘要: A process for making a latex emulsion including contacting at least one amorphous polyester resin with at least two organic solvents to form a resin mixture, adding a neutralizing agent, and deionized water to the resin mixture, removing the solvent from the formed latex, and separating the solvent from water. Further, the process is carried out above the resin Tg for making the latex, which drives the latex particle size under 100 nm, where toners made from the latex show improved charging performance.

摘要: Toners and processes useful in providing toners suitable for electrophotographic apparatuses, including apparatuses such as digital, image-on-image, and similar apparatuses. In particular, emulsion aggregate toner compositions that use two different emulsion aggregation (EA) technologies and which comprise a base resin composed of both styrene-acrylate and polyester resins. These toner compositions further include polyaluminum chloride (PAC) instead of the more commonly used aluminum sulfate as the flocculant or aggregating agent.
