Patent ID: 6962764

Claim:
A process of preparing a chemical toner comprising: (a) mixing together a latex and a first composition to result in a second composition, wherein the first composition includes a colorant dispersion and an optional wax dispersion, wherein the latex comprises polymeric particles dispersed in an aqueous phase, wherein the polymeric particles comprise a compound with a functional group covalently bound and with the functional group disposed on the particle surface, wherein the compound exhibits a molecular weight polydispersity of from about 1.1 to about 3.0; (b) heating the second composition at an aggregation temperature which is at or below the glass transition temperature of the polymeric particles to form toner sized aggregates; (c) adding a coagulant to the second composition prior to or during the heating of the second composition at the aggregation temperature to promote formation of the toner sized aggregates; (d) stabilizing the particle size of the toner sized aggregates, resulting in a stabilized composition; and (e) heating the stabilized composition at a coalescence temperature which is above the glass transition temperature of the polymeric particles to coalesce the toner sized aggregates into toner particles.
