TITLE CHROMIUM, MOLYBDENUM AND TUNGSTEN COMPOUNDS AS CHARGING ADJUVANTS FOR ELECTROSTATIC LIQUID DEVELOPERS ABSTRACT OF THE INVENTION An electrostatic liquid developer consisting essentially of (A) a nonpolar liquid having a Kauri- butanol value of less than 30, present in major amount; (B) thermoplastic resin particles less than 30 µm average particle size; (C) a chromium, molybdenum or tungsten compound having an oxidation state of at least +3 wherein the anionic component is as defined above, and (D) a nonpolar liquid soluble ionic or zwitterionic charge director compound. The process of preparation of the electrostatic liquid developer is also described. The liquid developers are useful in copying, color proofing including digital color proofing, lithographic printing plates, and resists.
