Microsuspension processes for toner compositions |
摘要 |
A process for the preparation of toner compositions which comprises dissolving a polymer, and optionally a pigment in an organic solvent; dispersing the resulting solution in an aqueous media containing a surfactant, or mixture of surfactants; stirring the mixture with optional heating to remove the organic solvent thereby obtaining suspended particles of about 0.05 micron to about 2 microns in volume diameter; subsequently homogenizing the resulting suspension with an optional pigment in water and surfactant; followed by aggregating the mixture by heating thereby providing toner particles with an average particle volume diameter of from between about 3 to about 21 microns when said pigment is present.
