    摘要: A process for the preparation of toner which involves i) flushing a colorant into a sulfonated polyester resin; ii) mixing an organic soluble dye with the colorant polyester resin of i); iii) dispersing the resulting mixture into warm water thereby enabling the formation of submicron particles; iv) allowing the resulting solution to cool below about, or about equal to the glass transition temperature of said sulfonated polyester resin; v) adding an alkali halide solution and heating; and optionally vi) recovering said toner, followed by washing and drying.

    摘要: A process for the preparation of encapsulated toner compositions which comprises dispersing a mixture of addition monomers, an optional preformed polymer resin, a free radical initiator, a colorant comprised of a pigment, dye or mixtures thereof, and shell forming monomer in an aqueous medium containing a cellulose polymer and a first ionic surfactant thereby forming a stable microdroplet suspension; and subsequently adding an aqueous solution of a second stabilizing surfactant followed by the formation of a soluble monomer forming shell wall by interfacial polymerization, and thereafter initiating and completing the core resin-forming free radical polymerization by heating thereby resulting in toner compositions with an average volume particle size of from about 3 to about 7 microns.
