    摘要: A process for the preparation of inks comprised of i) flushing pigment into a sulfonated polyester resin, and which resin possesses a degree of sulfonation of from between about 2.5 and about 20 mol percent; ii) dispersing the pigmented polyester resin in water at a temperature of from about 40.degree. C. about 95.degree. C. by a polytron shearing device operating at speeds of from about 100 to about 5,000 revolutions to yield stable pigmented submicron sized particles of from about 5 to about 150 nanometers; and thereafter separating said submicron particles and mixing said submicron particles with water.

    摘要: A process for the preparation of toner compositions comprising:(i) preparing an emulsion latex comprised of sodio sulfonated polyester resin particles of from about 5 to about 500 nanometers in size diameter by heating said resin in water at a temperature of from about 65.degree. C. to about 90.degree. C.(ii) preparing a pigment dispersion in a water by dispersing in water from about 10 to about 25 weight percent of sodio sulfonated polyester and from about 1 to about 5 weight percent of pigment;(iii) adding the pigment dispersion to a latex mixture comprised of sulfonated polyester resin particles in water with shearing, followed by the addition of an alkali halide in water until aggregation results as indicated by an increase in the latex viscosity of from about 2 centipoise to about 100 centipoise;(iv) heating the resulting mixture at a temperature of from about 45.degree. C. to about 80.degree. C. thereby causing further aggregation and enabling coalescence, resulting in toner particles of from about 4 to about 9 microns in volume average diameter and with a geometric distribution of less than about 1.3; and optionally(v) cooling the product mixture to about 25.degree. C. and followed by washing and drying.
