Summary:Negative, liquid electrostatic developer consisting essentially of (A) nonpolar liquid having Kauri-butanol value less than 30, present in major amount, (B) thermoplastic resin particles having a colorant and an inorganic metal salt as defined dispersed therein and average particle size by area being less than 10 mu m, and (C) nonpolar liquid soluble ionic or zwitterionic compound which imparts a negative charge to the thermoplastic resin particles. Optionally additional adjuvants are present. The liquid electrostatic developer is useful in copying, making proofs including digital color proofs, lithographic printing plates, and resists. n
