Surface-treated charge control agents, and method for producing the same

摘要

A composition, for use in such applications as electrostatographic toners and developers, containing a charge control agent adsorbed onto flow aid particles may be produced by a solution coating process including: (1) dissolving the charge control agent in at least one solvent; (2) adding the flow aid particles to the solvent and forming a suspension; (3) removing the solvent from the suspension after adsorption of the charge control agent onto the flow aid particles has occurred; and (4) drying and milling the material remaining after the solvent is removed from the suspension.
