    摘要: A process comprising heating a mixture of colorant and latex in the presence of a coagulant and a silicate salt, and wherein said heating comprises a first heating equal to or below about the glass transition temperature of a polymer contained in said latex, and a second heating equal to or about the glass transition temperature of a polymer contained in said latex; wherein said first heating enables the formation of aggregates and said second heating enables the fusion of said colorant and said polymer; and optionally wherein said silicate is contained in an alkali metal hydroxide.

    摘要: A toner process comprising aggregating or coagulating a latex emulsion comprising a resin, a colorant and wax particles using an amount of polymetal ion coagulant to provide core particles; heating the core particles to provide micron size aggregates; optionally adding a second resin emulsion; adding a sequestering or complexing component and a base to remove the polymetal ion in a controlled manner; further heating the mixture to provide toner particles; and optionally, isolating the toner particles.
