    摘要： A toner composition is provided which contains a polyester resin with hydrophilic groups and hydrophobic end groups and a colorant, wherein said polyester resin is of the formula: wherein R is an alkylene group; X is an aromatic hydrocarbon; Y is selected from the group consisting of an alkali and an alkaline earth metal salt of an arylenesulfonate or an alkylenesulfonate; R′ is a hydrophobic group, and m and n represent the number of random segments of from about 50 to about 300 for n, and from about 20 to about 2,000 for m, and m is less than 20 times n.

    摘要： In-situ processes for making bichromal particles include forming particles having a one color and an anionic surface charge, and separately forming particles having another color and a cationic surface charge. The anionic and cationic particles are mixed, and aggregated to form bichromal aggregates. The aggregated particles are coalesced to form bichromal particles. The bichromal particles can be used in gyricon sheets and gyricon displays.

    摘要： A process involving, for example, providing or generating an emulsion latex comprised of sodio sulfonated polyester resin particles by adding with shearing to the latex a colorant dispersion comprising from about 20 to about 50 percent of a predispersed colorant in water, followed by the addition of an organic or an inorganic acid; heating the resulting mixture at a temperature of from about 45° C. to about 65° C. followed by the addition of an water insoluble metal salt or water insoluble metal oxide thereby releasing metal ions and permitting aggregation and coalescence, resulting in toner particles; and optionally cooling the mixture and isolating the product.
