Abstract:
1. A process comprising: forming an emulsion by contacting monomer components of a latex resin with a stabilizer of the following formula: where R1 is a hydrogen or methyl group; R2 and R3 are independently selected from alkyl groups containing about 1 to about 12 carbon atoms and a phenyl group; and n is from about 0 to about 20; adding a portion of the emulsion to a reactor; contacting the emulsion in the reactor with a crosslinker; optionally adding an initiator to the reactor; forming a seed particle comprising a gel latex in the reactor; adding additional monomers comprising the latex resin and optionally additional stabilizer to the reactor; and recovering the resulting latex resin and contacting the resulting latex resin with an optional colorant dispersion and an optional wax dispersion to form toner particles, wherein the gel latex is present in an amount sufficient to reduce the particle size of the resulting latex resin as compared to a latex resin prepared without said seed particle comprising said gel latex, and wherein the stablizer used results in larger particle sizes when prepared without said seed particle comprising said gel latex.
