ABSTRACT:
Dispersion polymerization process for producing colored toner particles comprising admixing a colorant with a monomer to form an oil soluble organic phase, admixing a polymerization initiator with the organic phase, admixing the organic phase with an aqueous phase containing a suspending agent and an inorganic salt therein under polymerization conditions to form a suspension, polymerizing the suspension under continuous agitation to provide polymer particles containing the colorant and having a particle size in the range of from about 1 micron to about 100 microns, and recovering the polymer particles. The inorganic salt inhibits polymerization in the aqueous phase. Developer compositions and processes for developing electrostatic latent images are also disclosed.
