摘要： A method of making particles suitable for use as toners includes forming a mixture of sulfonated olyester resin, a colorant dispersion and optionally a wax dispersion, homogenizing the mixture, adding a coagulant to the mixture to aggregate the mixture to form aggregated particles, and coalescing the aggregated particles to form coalesced particles. In the method, when a predetermined average particle size is achieved during the aggregation and/or coalescing step, a complexing agent that complexes with ions of the coagulant is added in an amount effective to substantially halt any further particle growth. The complexing agent is believed to halt further growth by complexing with free coagulant ions still in the solution.

摘要： A toner of a sulfonated polyester resin and at least one colorant is made to contain from about 0.01% by weigh to about 3% by weight of dry toner in total of lithium, sodium, zinc and calcium. The sulfonated polyester resin may be an alkali metal sulfonated polyester resin, wherein the alkali metal may be sodium and/or lithium. The toner may be formed in an emulsion aggregation process in which an alkali (II) metal salt such as a zinc salt and/or a calcium salt is used as an aggregating agent.

摘要： Ultra low melt toner compositions with improved non-additive heat cohesion are disclosed. These toner compositions include toner particles comprising amorphous resins containing at least one unsaturated moiety, and when the toner particles are surface treated with a peroxy compound and optionally with a peroxy promoter compound, the surface of the toner particles is cross-linked to form a thin, robust shell. Processes for preparing the toner compositions are also described.

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.
