| Zusammenfassung: | Liquid electrostatic developer having improved charging characteristics consisting essentially of (A) nonpolar liquid having a Kauri-butonal value of less than 30, (B) thermoplastic resin particles substantially nonsoluble in nonpolar liquid and aromatic hydrocarbon at ambient temperature and having an average by area particle size of less than 10 mu m, (C) nonpolar liquid soluble ionic or zwitterionic compound, and (D) aromatic hydrocarbon having a Kauri-butonal value of greater than 30. The electrostatic liquid developers are useful in copying making proofs including digital color proofs, lithographic printing plates, and resists. |
