Abstract
A process for making a latex emulsion suitable for use in a toner composition includes co-emulsifying a bio-based resin with an insoluble component, such as a pigment or wax, whereby the resin encapsulates the insoluble component. The resulting latex, including the insoluble component encapsulated in the resin, may then be utilized to form a toner. The insoluble component may thus be included in toner particles, which might otherwise be difficult to achieve, using emulsion aggregation processes.
Claims20
A process comprising:
- contacting at least one polyester resin with at least one organic solvent, the solvent being immiscible with water, to form an organic phase;
- contacting the organic phase with a water phase comprising a component insoluble in the organic phase selected from the group consisting of wax dispersions, pigment dispersions, and combinations thereof;
- mixing the organic phase and the water phase;
- and
- evaporating the organic solvent to form a latex comprising the resin and the insoluble component.

A process comprising:
- contacting at least one polyester resin comprising a bio-based resin comprising monomers selected from the group consisting of a fatty dimer acid, a fatty dimer diol, D-isosorbide, naphthalene dicarboxylate, azelaic acid, succinic acid, cyclohexanedioic acid, naphthalene dicarboxylic acid, terephthalic acid, glutamic acid, and combinations thereof, with at least one organic solvent immiscible with water to form an organic phase;
- contacting the organic phase with a water phase comprising a component insoluble in the organic phase selected from the group consisting of wax dispersions, pigment dispersions, and combinations thereof;
- mixing the organic phase and the water phase;
- and
- evaporating the organic solvent to form a latex comprising the insoluble component encapsulated by the resin.
