发明名称 Metal alkoxide modified resins for negative-working electrostatic liquid developers.
摘要 <p>Negative-working electrostatic liquid developer consisting essentially of (A) nonpolar liquid having Kauri-butanol value less than 30, present in major amount, (B) particles, average by area particle size of less than 10 mu m, of a polymer prepared from the reaction product of polymeric resin having free carboxyl groups and a metal alkoxide as defined, and (C) nonpolar liquid soluble ionic or zwitterionic charge director compound. Optionally a colorant and an adjuvant compound are present. Process of preparation of electrostatic liquid developers is described. The developer is useful in copying, making proofs including digital color proofs, lithographic printing plates, and resists.</p>
