A positive charged electrostatic liquid developer consisting essentially of (A) a non-polar liquid having a Kauri-butanol value of less than 30, (B) thermoplastic resin particles, average by area particle size of less than 10 mu m, (C) a charge director compound, and (D) at least one inorganic acid having a solubility of at least 0.5% based on the weight of charge director compound in a mixture of (A) and (C) and represented by the formula: HxY wherein x is an integer from 1-4 and is equal to the negative charge on the anion, Y is a moiety selected from the group consisting of Cl<->, F<->, NO3<->, NO2<->, PO4<-><3>, SO4<-><2>, SO3<-><2>, ClO4<->, and IO4<->. The liquid developer is useful in copying, color proofing, digital color proofing, making lithographic printing plates, and resists. |
