Abstract
A process for preparing a polymer-encapsulated carbon black material is described. The process comprises: (a) preparing a mixture of an ionic monomer, a stabilizer and carbon black in water; (b) adding an initiator; (c) adjusting the temperature to a temperature above room temperature; and (d) adding at least one other monomer and a charge control agent to obtain the material. The process is performed under continuous stirring. The polymer-encapsulated carbon black material is surfactant-free and is used in the production of toners.
