Zusammenfassung:Liquid electrostatic developer consisting essentially of A. nonpolar liquid having Kauri-butanol value less than 30, present in major amount, B. thermoplastic resin particles, average by area particle size less than 10 mu m, consisting essentially of mixture (1) 80-95% by weight thermoplastic resin and (2) 20 to 5% by weight multiblock copolymer compound as defined, and C. charge director compound. The process of preparation is also defined. The said developer is useful in copying, making proofs, including digital color proofs, lithographic printing plates, and resists.
