    摘要: A process for the preparation of toner involving (i) aggregating a colorant dispersion containing a suitable surfactant with a latex emulsion containing an anionic surfactant, a nonionic surfactant, and a water miscible chain transfer agent, or a nonionic surfactant with chain transfer characteristics to form toner sized aggregates; (ii) coalescing or fusing said aggregates; and optionally (iii) isolating, washing, and drying the resulting toner.

    摘要: A layered particle for use in forming toner may be formed by forming a core region; polymerizing in the presence of the core region at least one monomer feed to form at least one intermediate layer on the core region; and polymerizing in the presence of the core region with at least one intermediate layer thereon a final monomer feed. In the process, each monomer feed is different from the previous monomer feed so as to form different polymer layers.
