The presently claimed process for the production of a solid pigment/resin dispersion comprises the steps of mixing together a particulate pigment, a solid resin carrier, a water-immiscible organic solvent in which the carrier is at least partially soluble, water, and, optionally, a water miscible solvent until the mixture separates into an aqueous phase and a coherent phase comprising resin, pigment and organic solvent; separating water from the coherent phase; and continuing to mix the coherent phase while removing the organic solvent under the action of heat and/or reduced pressure until a dry particulate material comprising a pigment and resin is formed. |
