Abstract
Electrostatic liquid developer having improved charging characteristics comprising PA1 (A) nonpolar liquid having a Kauri-butanol value of less than 30, present in a major amount, PA1 (B) thermoplastic resin particles having an average by area particle size of less than 10 .mu.m, PA1 (C) nonpolar liquid soluble ionic or zwitterionic compound, and PA1 (D) at least one aminoalcohol compound. The electrostatic liquid developer is useful in copying, making proofs including digital color proofs, lithographic printing plates, and resists.
