Abstract: Processes for producing emulsion aggregation toners are provided. In embodiments, methods of the present disclosure may be utilized to produce toners suitable for low melt applications, including use in flexible packaging applications, where low pile height is desired for low cost and flexibility. In embodiments, the EA toners may be prepared by optimizing the particle size of the emulsion, the choice of and amount of aggregating agent utilized, and the solids content of the emulsion.

Abstract: A toner comprising: at least one amorphous polyester resin, at least one crystalline polyester resin, and one or more optional ingredients selected from the group consisting of colorants, optional waxes, and combinations thereof; and a gel comprising a crosslinked polymer comprising copolymers of styrene and acrylates, copolymers of styrene and butadiene, copolymers of styrene and methacrylates, copolymers of acrylates and methacrylates, copolymers of methacrylates and acrylic acid, copolymers of acrylates and acrylonitriles, copolymers of methylstyrene and butadiene, copolymers of methacrylates and butadiene, copolymers of acrylates and butadiene, copolymers of styrene and isoprene, copolymers of methylstyrene and isoprene, copolymers of methacrylates and isoprene, copolymers of acrylates and isoprene, and combinations thereof. In embodiments, the toner particles may have a core-shell configuration, with the gel in the core, the shell, or both. The gel may prevent a crystalline resin in the core of the toner particles from migrating to the toner surface.

Abstract: Toner particles are provided which may, in embodiments, include a core possessing at least one polyester resin in combination with a colorant, optional wax, and optional other additives, and a shell over the core including a high molecular weight amorphous polyester resin. The high molecular weight amorphous polyester resin in the shell may prevent any crystalline polyester resin in the core from migrating to the toner surface.

Abstract: 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 presenc e of a coagulant, aggregating to form particles, coalescing to form fused particles , and removing the fused particles from the aqueous dispersion. Wax dispersions ca n be added either after mixing or during aggregation, so that wax is excluded fro m the core of the toner particles.
