Abstract (en)
Liquid electrographic developers are disclosed comprising an electrically insulating liquid carrier, dispersed toner particles, and dissolved in the carrier a polymeric charge-control agent and a polymeric charging agent. The charge-control agent is an addition copolymer of a quaternary ammonium salt monomer, a monomer having -COOH, -SO3H or -PO3HR acidic function wherein R is hydrogen or alkyl, and a solubilizing monomer. The charging agent is an addition copolymer of a polar monomer and a solubilizing monomer.
