Electrostatographic toner and method for the preparation thereof

摘要

A method is described for the preparation of electrostatographic toner particles which involves the surface treatment of pigments using a low melting point highly reactive wax. The method involves preparing a melt dispersion comprising a pigment, a polymeric binder and a low melting point wax at elevated temperatures, the wax melting and coating the surface of the pigment. The melt dispersion is then used as a component of the organic phase in a limited coalescence process.
