Zusammenfassung:Electrostatic liquid developer having improved charging characteristics consisting essentially of (A) nonpolar liquid having a Kauri-butanol value of less than 30, present in a major amount, (B) thermoplastic resin particles having an average by area particle size of less than l0 mu m, (C) nonpolar liquid soluble ionic or zwitterionic compound, and (D) a polyhydroxy compound, preferably soluble in the developer in an amount of at least 2% by weight. The electrostatic liquid developers are useful in copying, making proofs including digital color proofs, lithographic printing plates, and resists.
