摘要：
Negatively charged coated toner particles are provided that comprise a polymeric binder particle and a coating material. The coating material comprises at least one visual enhancement additive coated on the outside surface of the polymeric binder particle. Electrographic toner compositions comprising these particles, and methods of making these particles particularly by magnetically assisted impact coating processes are also provided.
