ABSTRACT:
A method for making coated pigment particles by forming a suspension of the desired pigment particles in a medium that also comprises a polymer characterized by having hydrophobic moieties on the polymer backbone and ionic moieties that are present on, or can be formed on a polymer side chain or at the polymer terminals; allowing the suspension of pigment particles to contact said polymer at a temperature above the softening point of the polymer, allowing the resultant suspension to cool to a temperature below the solidification temperature for the polymer while maintaining the pigment particles in suspension, and, if required, forming the ionic moieties.
