The present disclosure relates to a method for coating conductive metallic pigment particles, the method comprising: providing a first liquid carrier containing a dissolved resin and suspended conductive metallic pigment particles; effecting precipitation of the resin from the first liquid, such that a coating of the resin is formed on the conductive metallic pigment particles. Also disclosed herein are conductive metallic pigment particles, and an electrostatic ink composition comprising coated conductive metallic pigment particles.
