  • Patent number: 11767447
    Abstract: Provided herein is a topcoat composition comprising at least one fluorosilicone, a hydride-functional crosslinking agent, an infrared-absorbing filler, and at least one dispersant that is non-reactive with the hydride-functional crosslinking agent, by weight based on a total weight of the topcoat composition, wherein the topcoat composition has a degree of crosslinking between about 10 micrograms/hour/milligrams to about 20 micrograms/hour/milligrams. Further provided herein are methods of making the topcoat composition, as well as an imaging blanket and methods of reducing coating defects on a media coated using the imaging member.
    Type: Grant
    Filed: January 19, 2021
    Date of Patent: September 26, 2023
    Assignee: XEROX CORPORATION

  • Patent number: 6190818
    Abstract: A process for forming a dispersion including forming a mixture including agglomerates of primary particles, a film forming binder and a solvent for the binder, the primary particles having an average size of less than about 500 nanometers, applying sufficient heat energy to the mixture while stirring to disintegrate the agglomerates into separate primary particles having an average size of less than about 500 nanometers to form a dispersion substantially free of agglomerates, and slowly cooling the dispersion to maintain separation between the primary particles in the dispersion.
