Abstract
Dry, coated pigment particles are obtained by first suspending uncoated pigment particles in an appropriate medium and then coating the particles while in suspension, with a polymer that is at or above the softening point for that polymer. Coating of the pigment particles is achieved by allowing the suspension to cool to a temperature below the solidification temperature for the polymer. The coated pigment particles are then recovered.
