  • Flushed pigment and a method for making the same
    Patent number: 5108509
    Abstract: A pigment is formed in an aqueous slurry. A mixture of the pigmented slurry and a vehicle is subjected to high speed, high shear mixing action. The water is forced out of the solid pigment and replaced by the vehicle forming bead-like spherical conglomerates. The conglomerates grow into clusters in the dispersing phase during the mixing process. The clusters are filtered from the dispersing water phase forming a flushed pigment which is used for dispersion in ink systems.
    Type: Grant
    Filed: May 8, 1990
    Date of Patent: April 28, 1992
