Metallic pigment particles

A method for producing a conductive liquid electrophotographic ink composition, the method comprising:

• heating a polymer resin in a carrier fluid to dissolve the polymer resin;
• adding conductive metallic pigment flakes 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 flakes to form a suspension of at least partially coated conductive metallic pigment flakes in the carrier fluid;
• reheating the suspension of at least partially coated conductive metallic pigment flakes in the carrier fluid to a temperature at least 5° C. above a cloud point of the suspension;
• and
• cooling the suspension at a rate of at least or about 20° C. per hour to a temperature at least 5° C. below the cloud point, followed by cooling at a controlled rate of less than 7° C. per hour 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 flakes, thereby producing the conductive liquid electrophotographic ink composition.
