  • METHODS FOR RECYCLING BYPRODUCT OF POLYESTER RESIN PRODUCTION
    Publication number: 20140072912
    Abstract: Processes for preparing polyester resins as toner production components. The processes include reacting an organic diol and a cyclic alkylene carbonate to produce carbon dioxide (CO2) and a polyalkoxy diol. The carbon dioxide is reacted with an alkylene glycol or alkylene oxide to produce additional cyclic alkylene carbonate having the same chemical structure as the cyclic alkylene carbonate used to produce the polyalkoxy diol. The additional cyclic alkylene carbonate is added with the cyclic alkylene carbonate used to produce the polyalkoxy diol. The polyalkoxy diol can be reacted with an organic diacid or diester in preparing a polyester resin. To prepare a toner, the polyester resin can be contacted with at least one toner production component.

  • Extended zone low temperature non-contact heating for distortion free fusing of images on non-porous material
    Patent number: 8606165
    Abstract: A system for heated gas fusing of toner on non-porous substrates is provided. The system uses (1) an extended fusing zone held at lower temperatures than needed for a roll nip or radiant fuser, and (2) a very low melt toner which can be fused at greatly reduced temperatures compared to conventional toners. In one form, the system is realized through (a) the use of heated gas as the low temperature extended zone fusing technology, and (b) the use of ultra-low melt (ULM) toner—which requires significantly reduced temperature compared to conventional toner. On non-porous packaging substrates the use of heated gas can limit the substrate temperature to 100° C.

  • Co-emulsification of insoluble compounds with toner resins
    Patent number: 8563211
    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.
