Toner processes
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.
