Patent ID: 7553601

Claim:
A process comprising: contacting a first latex selected from the group consisting of styrenes, acrylates, methacrylates, butadienes, isoprenes, acrylic acids, methacrylic acids, acrylonitriles, and combinations thereof, 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 possessing functional groups comprising an alkaline resin selected from the group consisting of calcium resinates, beryllium resinates, magnesium resinates, strontium resinates, barium resinates, radium resinates, zinc resinates, aluminum resinates, copper resinates, iron resinates, and combinations thereof, to the aggregated toner core to form a shell over said toner core thereby forming a core-shell toner; heating the core-shell toner at a temperature above the glass transition temperature of the first latex; and recovering said toner.
