Abstract: A polymer composite comprises a polymer matrix having, dispersed therein, layers of an inorganic material derived from a multilayered inorganic material such as clay intercalated with an inorganic intercalant. The multilayered inorganic material may also be intercalated with an organic material.
Abstract: The toner particles of this invention comprise pigment and a resin. The resin comprises a novel polymer formed from ethylenically unsaturated monomers, macromeric moieties that render the resin dispersible in hydrocarbon solvents, and a surface-release promoting moiety. When used for toner particles the polymer further comprises charge directing chelating moieties. The toner particles also include a charge director, preferably a metal cation. The toner particles, when dispersed in a carrier liquid, are useful as liquid toners for electrographic or electrophotographic processes.
