    Hewlett-Packard’s Patent Applications:

    The Hewlett-Packard Company has built a strong market presence for its printing products so it wouldn’t be surprising to see it pursuing innovations in ink products. Improvements to the use of metallic pigments which achieve a more desirable optical density during printing is the focus of U.S. Patent Application No. 20140342279, entitled Polymer-Encapsulated Metallic Ink Particles and Metallic Electrophotographic Inks. The method for making polymer-encapsulated metallic ink particles claimed here involves forming an ethylene-based polymeric resin powder, mixing that powder with a metallic pigment powder to form a powder mixture, melting that mixture to form a metallic powder melt, adding a non-polar carrier and processing the resulting slurry in a microfluidizer. The resulting metallic electrophotographic ink has a reduced flop index, or a reduced change in the lightness of a metallic color when viewed at different angles. Not every HP ink innovation we viewed is focused on traditional print media, however, as is evidenced by U.S. Patent Application No. 20140376082, filed under the title Multi-Stable Electronic Inks. This patent application would protect a compound that includes a segment formed of hydrocarbons having either nitrogen or oxygen in the carbon backbone, as well as other hydrocarbon segments. The compound is used as a multi-stable ink for an electrokinetic display that can maintain an image or text when the display power is reduced or turned off entirely.
