    Abstract: A process for the preparation of a toner by mixing a colorant, a latex, optionally a wax and a polyamine salt coagulant to form toner size aggregates, wherein the polyamine salt is then neutralized or converted to an amide or hydrolyzed to an acid by the introduction of a base followed by a pH reduction with an acid to enable rapid coalescence or fusion of the aggregates.
