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.
