  • Patent number: 8778584
    Abstract: The present disclosure provides toners and methods for their production. In embodiments, the amount of coagulant utilized in producing those toners may be less than amounts currently in use, which may have a beneficial effect by reducing the time for coalescence. Modified waxes may also be utilized which provide excellent gloss and charging characteristics.

  • Patent number: 8455171
    Abstract: The present disclosure provides processes for reducing the particle size of latex resins and toners produced with such resins. In embodiments, a carboxylic acid may be added to materials utilized to produce a latex and reduce the particle size of the resulting latex particles and toner particles. In accordance with the present disclosure, one may be able to utilize materials for the production of latex resins and toners which may otherwise produce particles that are too large in the absence of the carboxylic acid.

  • Patent number: 8383310
    Abstract: The present disclosure relates to a binder resin system suitable for use in forming toner compositions. In embodiments, the binder resin system includes at least one amorphous resin, at least one crystalline resin, and at least one fatty acid salt. The presence of the fatty acid salt reduces plasticization which may otherwise occur upon combining the amorphous and crystalline resins, thereby increasing the glass transition temperature of the binder resin, as well as any toner produced with such binder resin. Toners produced with the disclosed binder resin may also include one or more optional ingredients such as optional colorants, optional waxes, and combinations thereof.

  • Patent number: 8252493
    Abstract: Single component toners are provided with at least one surface additive including a large polymeric spacer, and processes for producing the same. In embodiments, the toner is a non-magnetic single component toner produced by emulsion aggregation methods. The large polymeric spacer additives provide excellent flow characteristics to the resulting toners, and reduce the incidence of clogging failure and print defects such as ghosting, white bands, and low toner density compared with conventionally produced toners.
