  • Pigment for use in inkjet recording medium coatings and methods
    Patent number: 7377975
    Abstract: Pigment suitable for use in coating compositions for inkjet recording media. Surfaces of an inorganic particulate are interacted with a water-soluble polyvalent metal salt in an aqueous medium. The treated particle surfaces have a significant cationic surface charge imparted to them. The salt is a salt of a metal of Group II or Group III of the Periodic Table. Inkjet recording media treated with a coating composition containing the above pigment provide high density, fast-drying, and non-feathering ink images with suitable water fastness, while the coating compositions also offer cost advantages and improved rheology at higher pigment levels over coatings based on silica pigments.
    Type: Grant
    Filed: September 20, 2006
    Date of Patent: May 27, 2008
    Assignee: J.M. Huber Corporation
    Inventors: Ching-Yih Chen, Ricky L. Giddens, Richard D. Carter
