Patent ID: 7794911

Claim:
A process comprising: contacting a first latex having a glass transition temperature from about 45° C. to about 65° C., an aqueous colorant dispersion, and an optional wax dispersion to form a blend; adding a base to increase the pH to a value of from about 4 to about 7; heating the blend at a temperature below the glass transition temperature of the latex to form an aggregated toner core; adding a second latex having a glass transition temperature from about 45° C. to about 70° C. to the aggregated toner core, wherein the second latex possesses functional groups selected from the group consisting of silanes, fluoro acrylates, fluoro methacrylates, fluoro styrenes, and combinations thereof, and forms a shell over said toner core forming a core-shell toner; heating the core-shell toner at a temperature above the glass transition temperature of the first latex and second latex; and recovering said toner.
