摘要:
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, -S0 3 H or -P0 3 HR 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.

摘要:
A replenishable liquid electrographic developer and method for manufacture of the developer are provided in which a stable dispersion comprising wax particles, a dispersing liquid and a dispersing agent for the wax is combined with a liquid electrographic toner formulation. Toner images formed from the resulting developer exhibit improved abrasion resistance.
摘要:
A process for forming microcellular imaging elements comprising a support having first and second major surfaces. a planar array of microcells 1 to 200 microns in width opening toward the first major surface, which comprises selectively introducing a first imaging composition into a first set of microcells. and a second, differing imaging composition into a second set of microcells forming an interlaid pattern with said first set of microcells, characterized in that the portion of the support (100) having the microcells (102) is photoconductive. and in that an electrostatic charge pattern is established on said support differentiating said first and second sets of microcells, and a first electrographic imaging composition is introduced selectively into the first set of microcells. The support optionally has an electrically conductive layer (116).
