  • Toner coagulant processes
    Patent number: 6582873
    Abstract: A toner process including, for example, mixing a latex with a colorant wherein the latex contains resin and an ionic surfactant, and the colorant contains a surfactant and a colorant; adding a polyaluminum chloride; affecting aggregation by heating; adding a chelating component and a base wherein the base increases the pH of the formed aggregates; heating the resulting mixture to accomplish coalescence; and isolating the toner.

  • Toner processes
    Patent number: 6541175
    Abstract: 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.
