ABSTRACT:
Toner with well-dispersed component subparticles is prepared by a method wherein an attritor is initially used to disperse the subparticles in a core monomer, and attrition is continued during initial polymerization of the monomer. Interfacial polymerization is then performed in a preferred embodiment to form encapsulated toner particles.
