摘要：
Positive-working electrostatic liquid developer consisting essentially of(A) nonpolar liquid having Kauri-butanol value less than 30, present in major amount,(B) thermoplastic resin particles having an average particle size by area of less than 10 .mu.m, and(C) an AB diblock copolymer charge director compound as defined. Optionally a colorant and charge adjuvant are present. The process of making the electrostatic liquid developer is described. The electrostatic liquid developer is useful in copying, making proofs including digital color proofs, lithographic printing plates, and resists.
