  • Toner compositions
    Patent number: 8092973
    Abstract: The present disclosure provides processes for reducing the particle size of latex resins and toners produced with such resins. In embodiments, a gel latex may be formed as a seed particle and then utilized to form latex resins and toner particles. In accordance with the present disclosure, one may be able to utilize materials for the production of latex resins and toners which may otherwise produce particles that are too large in the absence of the gel latex.
    Type: Grant
    Filed: April 21, 2008
    Date of Patent: January 10, 2012
    Assignee: Xerox Corporation
    Inventors: Zhen Lai, Chieh-Min Cheng, Robert D. Bayley, Grazyna E. Kmiecik-Lawrynowicz, Maura A. Sweeney, Daniel G. Marsh, Emily L. Moore, Shigang Qiu, Tie Hwee Ng

  • Process of painting with inks with colored resin emulsion particles
    Patent number: 6299941
    Abstract: An aqueous ink jet ink composition comprised of water, colorant, and colored resin emulsion particles generated from olefinic monomers, wherein at least one of said olefinic monomers contains a colorant, wherein the olefinic colorant component is prepared from the condensation reaction of a functional colorant with an olefinic containing reactive material, and which reaction generates wherein Dye represents a colorant chromophore, and R is a carbonyl, carboxylate, oxygen, or arylene, and R′ is hydrogen or alkyl.
