Abstract: Disclosed herein are formulations and processes for the preparation of pigment and wax dual dispersions by (1) providing a solution comprising a water and at least one surfactant in a dispersion apparatus comprising a container, a rotor-stator homogenizer, and a piston homogenizer coupled via a recirculation device; (2) adding at least one pigment to the solution; (3) forming a pigment dispersion by flowing the at least one pigment and the solution to the rotor-stator homogenizer via the recirculation device; (4) adding at least one wax to the pigment dispersion; and (5) flowing the at least one wax and pigment dispersion to the piston homogenizer via the recirculation device until a pigment and wax dual dispersion is formed. Also disclosed herein are pigment and wax dual dispersions, as well as a dispersion apparatus for preparing pigment and wax dual dispersions. In certain embodiments, a dispersion apparatus for preparing a pigment and wax dual dispersion may comprise a container, a rotor-stator homogenizer, a piston homogenizer, and a recirculation device coupled to the container and the homogenizers that allows a dispersion to flow between the container and the homogenizers.

Abstract: The present disclosure provides processes for making inorganic or organic colorant dispersions using an acoustic mixer, where such dispersion may be used to make toner. Such processes apply low frequency, high intensity acoustic energy and a consistent shear field throughout an entire mixing vessel and provide uniform dispersion of colorants within minutes.
