Abstract

An improved process for obtaining colored toner compositions by dispersion polymerization which comprises providing a monomer solution with stabilizer therein, polymerizing the resulting mixture, adding thereto a dye solution comprised of an organic solvent having dissolved therein oil soluble dyes, causing the dye solution to diffuse into the polymer particles, and subsequently separating the resulting toner particles, wherein the stabilizer is permanently attached to the toner polymer particles.
