ABSTRACT:
Pigments may be encapsulated by a process comprising the steps of (1) mixing a high solids pigment presscake with ammonia and an ammonia-soluble resin to form a fluid mixture, (2) removing sufficient water from the mixture to form a kneadable mass, and (3) dispersing the mass under conditions of high shear to yield a finely divided encapsulated pigment presscake.
