20140197364 | UV Red Fluorescent EA Toner - The present disclosure relates to a toner design for a clear UV red fluorescence toner having a high lanthanide complex pigment loading, including methods of making the fluorescence toner using a saccharide or a sugar acid to avoid complexation of lanthanide ions from the pigment, with lower aggregation and coalescence temperatures in the preparation of toner particles, where the particles exhibit a narrow size distribution and good xerographic performance. | 07-17-2014 |
20140322642 | Biophenols for Polyester Toner Resins - The present disclosure provides a polyester toner resin comprising a natural phenol used in manufacturing a toner for imaging devices. | 10-30-2014 |
20150132694 | SUPER LOW MELT TONER HAVING CRYSTALLINE DIESTERS WITH AN AROMATIC CORE - A toner includes a polymeric resin, optionally a colorant, and a small molecule crystalline diester having an aromatic core and a molecular weight less than 1,000 g/mol. The polymeric resin may be an amorphous resin and a mixture of the amorphous resin and the crystalline aromatic diester may be characterized by a reduction in glass transition temperature from that of the resin and by the lack of a significant solid to liquid phase transition peak for the small molecule compound as determined by differential scanning calorimetry, the enthalpy of fusion for the small molecule compound in the mixture being measured to be less than 10% of the enthalpy of fusion of the compound in pure form. Furthermore, the toner may be configured to have a crease fix minimum fusing temperature (MFT) less than or equal to the crease fix MFT of a benchmark ultra-low-melt emulsion aggregation toner. | 05-14-2015 |
20150197668 | POLYESTER PROCESSES - Disclosed are processes for the preparation of rosin diols accomplished by the reaction of a rosin acid with a glycerine carbonate in the presence of a catalyst, and subsequently where the rosin diol can be reacted with a diacid to generate an amorphous polyester resin. | 07-16-2015 |

20090209658 | Embolic compositions - Embolic compositions comprising macromers having a backbone comprising a polymeric backbone comprising units with a 1,2-diol or 1,3-diol structure, such as polyvinyl alcohol, and pendant chains bearing crosslinkable groups and, optionally, other modifiers. When crosslinked, the macromers form hydrogels having many properties advantageous for use as embolic agents to block and fill lumens and spaces. The embolic compositions can be used as liquid embolic agents and crosslinked in situ or as preformed embolic articles, such as microspheres. | 08-20-2009 |

20130306629 | Unity Cup - Unity Cup is designed to revolutionize the way wedding toast exchange is done. Usually the traditional wedding champagne glasses have to be held with arms crossed and locked, in order for the bride and the groom to show their unity. While they lock arms and try to get a sip they worry about spilling the drink on each other, so it creates anxiousness to both of them. The unity cup makes toasting so easy to conduct with out anxiousness or doubt that the drink might spill on the bride or the groom. Holding the cup together the flexibility of the unity cup allows the couple to drink facing each other from their respective right side. While they are drinking from same but separate cup, it brings them closer in proximity. Therefore the unity cup helps to avoid the awkward entanglement and gives the strong symbolism of unity. | 11-21-2013 |
