Flushed Pigment And A Method For Making The Same
US Patent:
5108509, Apr 28, 1992
Filed:
May 8, 1990
Appl. No.:
7/520462
Inventors:
John S. Booth - Fall River MA
Edward W. Makuch - N. Wesport MA
Edward W. Makuch - N. Wesport MA
Assignee:
Roma Color, Inc. - Fall River MA
International Classification:
C08K 500
US Classification:
106493
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.
