Patent ID: 8192912

Claim:
A process comprising: contacting an emulsion comprising at least one amorphous polyester resin in combination with at least one crystalline polyester resin with an optional wax and an optional colorant, the emulsion having a particle size of from about 50 nm to about 200 nm and a solids content of from about 10% to about 50% by weight; aggregating the particles by contacting the particles with from about 0.1 parts per hundred to about 2 parts per hundred of an aggregating agent selected from the group consisting of aluminum sulfate, polyaluminum chloride, polyaluminum bromide, polyaluminum fluoride, polyaluminum iodide, polyaluminum silicate, polyaluminum sulfosilicate, aluminum chloride, aluminum nitrite, aluminum sulfate, potassium aluminum sulfate, and combinations thereof to form aggregated particles; contacting the aggregated particles with at least one unsaturated polymeric resin in combination with a photoinitiator to form a shell over the aggregated particles; coalescing the aggregated particles to form toner particles; and recovering the toner particles.
