摘要: Toner compositions include a non cross linked resin; a cross linked resin or gel; a wax; and a colorant. Processes for preparing a toner include mixing a non-cross linked resin and a cross-linked resin or gel in the presence of a wax, a colorant, and a coagulant to provide toner size aggregates; adding additional non-cross linked latex to the formed aggregates thereby providing a shell over the formed aggregates; heating the shell covered aggregates to form toner; and, optionally, isolating the toner.

摘要: A process for making a latex emulsion suitable for use in a toner composition includes contacting at least one polyester resin with a bio-based solvent to form a resin mixture, adding a neutralizing agent and deionized water to the resin mixture, removing the solvent from the formed latex, and recovering the emulsion. The solvent removed from the formed latex may be re-used, making the process very environmentally friendly.

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.
