A process comprising aggregating an encapsulated colorant with colorant particles, and wherein said encapsulated colorant is generated by a miniemulsion polymerization;
- and wherein the encapsulated colorant and the colorant particles are carbon black, magnetite, cyan, yellow, magenta, or mixtures thereof.
A process comprising aggregating an encapsulated colorant with colorant particles, and wherein said encapsulated colorant is generated by a miniemulsion polymerization, and wherein during said miniemulsion a cosurfactant is present, and wherein the encapsulated colorant and colorant particles are carbon black, magnetite, cyan, yellow, or mixtures thereof.
A process for the preparation of toner which comprises
- aggregating colorant particles and an encapsulated colorant containing a polymer shell, an ionic surfactant, a cosurfactant, and a nonlonic surfactant;
- coalescing the aggregates generated;
- isolating, washing, and drying the toner;
- and wherein the encapsulated colorant and the colorant particles are carbon black, magnetite, cyan, yellow, magenta, or mixtures thereof.
