ABSTRACT:
A process for the preparation of encapsulated toner compositions which comprises a core dispersion obtained by adding pigment to a monomer, and wherein the pigment is sterically stabilized with a block copolymer; dispersing the resulting core dispersion into an aqueous solution containing an emulsifier; adding thereto an aqueous solution containing a shell monomer; encapsulating the core dispersion by interfacial polymerization of said shell monomer; and heating to initiate a free radical polymerization of the core monomer.
