  • Tunable Dielectric Compositions and Methods
    Publication number: 20100098838
    Abstract: Methods of tuning a printable dielectric layer, dielectric layers made by the method, and devices incorporating the dielectric layers. One such method includes printing a first dielectric composition and a second dielectric composition onto a substrate to provide a mixed composition. The first dielectric composition includes a first concentration of dispersed particles in a carrier fluid and the second dielectric composition includes a polymeric binder component. The mixed composition has a second concentration of particles.
    Type: Application

  • Bleed control using cationic dyes as dispersant in pigment dispersions
    Patent number: 6814793
    Abstract: An ink system comprising a first aqueous ink comprising a cationic pigment dispersion comprising a cationic dye and a pigment, and a second aqueous ink comprising an anionic dispersion comprising an anionic dispersant. The ink system reduces bleed between the two inks when they are applied side by side. The anionic dispersion in the second aqueous ink flocculates the cationic pigment dispersion in the first aqueous ink.
