  • Patent number: 8841055
    Abstract: An emulsion aggregation toner composition is disclosed that includes toner particles with at least one small crystalline molecule, such as a trans-cinnamic diester, at least one amorphous resin, optional waxes, coagulants, pigments, and combinations thereof. In other embodiments, the small crystalline molecule is biodegradable and can be made using raw materials derived from renewable resources. Such small crystalline molecules are also compatible with amorphous binder resins, to provide toner compositions with reduced minimum fusing temperatures without sacrificing electrical performance. Processes for preparing emulsion aggregation toner compositions are also described.
    Type: Grant
    Filed: April 4, 2012
    Date of Patent: September 23, 2014

  • Patent number: 7130108
    Abstract: A display member for use at a temperature greater than at least about 40° C. The display member includes an arrangement of a plurality of optically anisotropic rotatable elements comprising a purified polymer. The plurality of rotatable elements have a surface in contact with an enabling fluid, the rotatable elements being electrically dipolar in the presence of the enabling fluid and being subject to rotation upon application of an electric field.

  • Patent number: 5251468
    Abstract: The method and material of this invention eliminates the necessity of removing imbedded particles remaining after shot blasting by providing a method for surface finishing an orthopaedic implant wherein the blasting medium is bioactive. The surface finishing with bioactive material may also be used to clean the porous surface after sintering or diffusion bonding. Since the particles are made from bioactive material, it is not a concern if particles remain in the porous surface after blasting.
