摘要： A process for preparing toner particles and compositions adapted for use in preparing toners that comprise a blend of a first polyester resin with a second sharp melting polyester resin. The process includes forming an emulsion resin comprising a branched polyester resin, a crystalline polyester resin, a colorant, and optionally a wax. The resin mixture is aggregated using an aggregating agent, such as a zinc acetate solution, to form an aggregate mixture. The aggregate mixture is then coalesced at a temperature of from about 5 to about 20° C. above the Tg of the emulsion resin to produce the resultant toner particles.
