摘要：
A negatively charged liquid electrographic developer comprising an electrically insulating carrier liquid such as a paraffinic hydrocarbon fraction, having stably dispersed therein (a) a halogenated polymer, such as chlorinated polyethylene, and having dissolved therein (b) a copolymer of a quaternary ammonium salt monomer and a solubilizing monomer and (c) a copolymer of a polar monomer and a solubilizing monomer.
