Abstract
A method for producing a conductive liquid electrophotographic ink composition is described, the method comprising: heating a polymer resin in a carrier fluid to dissolve the polymer resin; adding conductive metallic pigment particles to be coated to the carrier fluid; cooling the carrier fluid to effect precipitation of the polymer resin from the carrier fluid such that a coating of the resin is at least partially formed on the conductive metallic pigment particles; reheating the suspension of partially coated conductive metallic pigment particles in the carrier fluid; and cooling the carrier fluid at a controlled rate to effect precipitation of the polymer resin from the carrier fluid such that a coating of the resin is formed on the conductive metallic pigment particles, thereby producing the conductive liquid electrophotographic ink composition.
