Abstract
Electrostatic liquid developer consisting essentially of PA1 (A) nonpolar liquid having Kauri-butanol value less than 30, present in major amount, PA1 (B) at least one thermoplastic resin having an average particle size by area of less than 10 .mu.m, and PA1 (C) at least one glyceride charge director as defined. Optionally a colorant and a charge adjuvant can be present. The elastrostatic liquid developer is useful in copying, making proofs, including digital color proofs, lithographic printing plates, resists and medical hardcopies.
