Toner particles of controlled morphology
Abstract:
The present invention is a method for the preparation of electrostatographic toner that includes the following steps. A polymer material is dissolved in an organic solvent to form an organic phase that includes a metal complex of zinc dimethyldithiocarbamate; zinc diethyldithiocarbamate; dibenzyldithiocarbamate, zinc di-n-butyldithiocarbamate. The organic phase is dispersed in an aqueous phase that includes a particulate stabilizer to form a dispersion and the resultant dispersion is homogenized. The organic solvent is evaporated and the resultant product is recovered, washed and dried.
