Liquid negative developer compositions for electrostatic copying containing polymeric charge control agent |
| abstract |
Disclosed is a developer composition which has improved depletion characteristics. The developer comprises an organic carrier containing latex particles comprising a major amount of a C1-C6 lower alkyl acrylate or methacrylate polymer, a pigment system, a charge control agent consisting of a copolymer of C2-C6 lower alkyl vinyl ether and a vinyl chloride, and an acrylic polymer gel for stabilizing the dispersion. The developer may be used in conventional copying equipment to make greater than about 20,000 copies of acceptable image density. |
