Abstract

An improved process for the preparation of encapsulated toner compositions which comprises mixing in the absence of solvent a core monomer, an initiator, pigment particles, a first shell monomer, stabilizer, and water; thereafter adding a second shell monomer thereby enabling an interfacial polymerization reaction between the first, and second shell monomers; and subsequently affecting a free radical polymerization of the core monomer.
