    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 pigment dispersion process includes providing a solution in a dispersion apparatus tha includes a container, a rotor-stator type homogenizer and a recirculation device. The process includes adding pigment particles to the solution to form a dispersion, flowing at least a portion of the dispersion to the homogenizer via the recirculation device, reducing a size of the pigment particles using the homogenizer, and recirculating the dispersion between the container and the homogenizer via the recirculation device. The dispersion system may include a container containing a dispersion that may contain an amount of deionized water, an amount of surfactant and an amount of pigment, and a recirculation device coupled to the container and to a rotor-stator homogenizer that allows the dispersion to flow between the container and the homogenizer.
