TONER PARTICLES OF CONTROLLED MORPHOLOGY
摘要:
The present invention is a method for the preparation of electrostatographic toner including the following steps. A polymer material is dissolved in an organic solvent to form an organic phase. The organic phase is dispersed in an aqueous phase that includes a particulate stabilizer and a salt including an anion selected from chloride, oxychloride, sulfate, perchlorate, nitrate, dihydrogen phosphate, lactate, trifluoromethylsulfonate, and trifluromethylhydrate and a cation selected from aluminum, iron (III), tin (II) and zirconium (IV), to form a dispersion. The dispersion is homogenized. The organic solvent is evaporated from the dispersion and the resultant product is recovered, washed and dried. In an alternate method the salt is added directly to the dispersion.
