  • Reactive media-ink system for ink jet printing
    Patent number: 5537137
    Abstract: An ink/media set is provided having improved durability. The ink contains an aqueous medium and a dye or pigment dispersion as the colorant. The media has a coating that contains a hydrophilic polymer and a reactive component. The printed media is exposed to an energy source that binds the ink to the media coating, and renders the coating more durable.
    Type: Grant
    Filed: February 6, 1995
    Date of Patent: July 16, 1996
    Assignee: E. I. Du Pont de Nemours and Company
    Inventors: Robert P. Held, Daphne P. Fickes, Joseph E. Reardon, Ray A. Work, III
