    摘要： A wax emulsion comprised of polyethylene wax and one or more surfactants in an aqueous medium, wherein the polyethylene wax has a degree of crystallinity of from about 50% to about 80% by weight of the polyethylene wax, is provided. The wax emulsion is made by emulsifying the polyethylene wax, one or more surfactants and an aqueous medium in a vessel at a temperature at or above the melting point of the polyethylene wax to form an emulsified product, and subsequently cooling the emulsified product to ambient temperature at a cooling rate of at least 10° C. per minute. The wax emulsion is preferably incorporated into toner particles prepared by emulsion/aggregation/coalescing.

    摘要： A process for the preparation of toner comprising blending an aqueous colorant dispersion and a latex emulsion containing resin; heating the resulting mixture at a temperature below about the glass transition temperature (Tg) of the latex resin to form toner sized aggregates; heating said resulting aggregates at a temperature above about the Tg of the latex resin to effect fusion or coalescence of the aggregates; redispersing said toner in water at a pH of above about 7; contacting the resulting mixture with a metal halide or salt, and then with a mixture of an alkaline base and a salicylic acid, a catechol, or mixtures thereof at a temperature of from about 25.degree. C. to about 80.degree. C.; and optionally isolating the toner product, washing, and drying.
