Patent ID: 7939237

Claim:
A method for making toner particles, the method comprising: providing nano-sized clay composites, wherein the nano-sized clay composites comprise polymer modified clays, wherein the nano-sized clay composites have a structure selected from the group consisting of an exfoliated structure, an intercalated structure, a tactoid structure, and mixtures thereof, and wherein clay particles of the nano-sized clay composites comprise from about 1% to about 20% by weight of the polymer modified clays; forming an emulsion for a core of the toner particles comprising at least a binder and at least one colorant, and forming an emulsion for a shell of the toner particles comprising at least one binder; adding the nano-sized clay composites to at least one of the emulsion for the core or the emulsion for the shell; subjecting the emulsion for the core to aggregation, wherein the core of the toner particles is formed by aggregation; and adding the emulsion for the shell after aggregating the core of the toner particles, and thereafter continuing aggregation to form a shell on the aggregated core.
