摘要： A positive, liquid electrostatic developer consisting essentially of(A) a nonpolar liquid having a Kauri-butanol value of less than 30, present in a major amount,(B) thermoplastic resin particles having dispersed therein a phosphorous-containing compound defined herein which is substantially insoluble or immiscible in the nonpolar liquid at ambient temperatures, the resin particles having an average by area particle size of less than 10 .mu.m, and(C) a nonpolar liquid soluble ionic or zwitterionic charge director compound, and process for preparation. The liquid developer is useful in copying, color proofing including digital color proofing, lithographic printing plates and resists.
