摘要： The present disclosure provides processes for increasing the shelf life and stability of resin emulsions suitable for use in forming toner particles. In embodiments, the pH of the resin emulsion is monitored, and a base is added as needed to maintain the pH of the emulsion at from about 6.5 to about 8. Maintaining the pH at from about 6.5 to about 8 prevents the degradation of the resin in the emulsion, including its molecular weight.

摘要： Toner particles comprise resin, wax and optionally colorants, and the wax is substantially excluded from the interior core of the toner particles. Processes for preparing such toner particles comprise providing an aqueous dispersion of resin particles and optionally colorants, mixing the aqueous dispersion in presence of a coagulant, aggregating to form particles, coalescing to form fused particles, and removing the fused particles from the aqueous dispersion. Wax dispersions can be added either after mixing or during aggregation, so that wax is excluded from the core of the toner particles.

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.
