摘要： A method of making particles suitable for use as toners includes forming a mixture of sulfonated polyester resin, a colorant dispersion and optionally a wax dispersion, homogenizing the mixture, adding a coagulant to the mixture to aggregate the mixture to form aggregated particles, and coalescing the aggregated particles to form coalesced particles. In the method, when a predetermined average particle size is achieved during the aggregation and/or coalescing step, a complexing agent that complexes with ions of the coagulant is added in an amount effective to substantially halt any further particle growth. The complexing agent is believed to halt further growth by complexing with free coagulant ions still in the solution.

摘要： A latex used for the preparation of toner particles by emulsion aggregation is prepared, using a controlled addition of anionic surfactants, without the use of a nonionic surfactant. Such a process comprises preparing an aqueous phase using a limited amount of anionic surfactant; preparing an emulsion of monomers in water with additional anionic surfactant and without a nonionic surfactant; adding a portion of the emulsion to the aqueous phase to initiate seed polymerization, in the presence of an initiator, to form seed polymer; and adding the remaining monomer emulsion to the composition to complete polymerization to form a latex polymer.
