| 106310290 | Hot melt type or wax containing | 11 |
| 20090165670 | HOT MELT INK - An ink composition which is solid at room temperature and liquid at a higher temperature, containing a substantially non-aqueous carrier composition and at least one dye, formed by at least one salt of the anthrapyridone series. | 07-02-2009 |
| 20100122642 | INKS INCLUDING CARBON NANOTUBES DISPERSED IN A POLYMER MATRIX - An ink having a polymer matrix including carbon nanotubes dispersed in a polymer; optionally one or more colorants; and optionally one or more waxes. | 05-20-2010 |
| 20100313788 | SOLID OR PHASE CHANGE INKS WITH IMPROVED PROPERTIES - A solid or phase change inkjet ink incorporating a polar acidic wax is described. The use of polar waxes as an ink additive improves the polarity of the ink and adhesion of the ink to paper. A method for applying the solid or phase change ink incorporating an acidic polar wax additive to form an image is also described. | 12-16-2010 |
| 20120227622 | PHASE CHANGE INKS - An ink composition that includes stearyl stearamide, N,N′-ethylene bisoleamide, at least one wax, at least one antioxidant, and at least one solvent dye colorant is useful as a phase change ink. | 09-13-2012 |
| 20130032056 | Phase Change Inks Containing Crystalline Trans-Cinnamic Diesters and Amorphous Isosorbide Oligomers - Disclosed is a phase change ink comprising: (a) a crystalline trans-cinnamic diester; and (b) an amorphous oligomer of isosorbide and a diacid. | 02-07-2013 |
| 20150307726 | TRANSPARENT SOLID INK COMPOSITION AND METHOD OF PREPARING THE SAME - A method of preparing a solid ink composition, comprising the steps of: reacting 15-25 parts by weight of base oil including coconut oil, palm oil and castor oil and 40-60 parts by weight of aliphatic organic acid of 10 to 20 carbon atoms with 7-15 parts by weight of a caustic soda solution (concentration: 40%) to saponify the base oil and to change the aliphatic organic acid into sodium salt thereof; mixing 3-10 by weight of glycerin, 10-20 by weight of ethanol, 0.1-1.0 by weight of a dye and 1-10 by weight of silica with the reaction product and then melting the mixture at 70-80° C.; and cooling the molten mixture. The solid ink composition prepared by the method is very transparent, and has excellent miscibility and stability because it is easily mixed with a water-soluble dye or a water-soluble fluorescent dye. | 10-29-2015 |
| 20160168402 | Water Cleanable Phase Change Ink For Ophthalmic Lens Marking | 06-16-2016 |
| 20180022922 | METHOD FOR PREPARING A COLORANT FOR USE IN A HOT MELT INK | 01-25-2018 |
| 106310300 | Petroleum derivative containing (e.g., paraffin or microcrystalline wax, etc.) | 2 |
| 20080245263 | Phase change inks containing colorant compounds - Disclosed is a phase change ink composition comprising a phase change ink carrier and a compound of the formula | 10-09-2008 |
| 20080245264 | Phase change inks containing colorant compounds - Disclosed is a phase change ink composition comprising a phase change ink carrier and a compound of the formula | 10-09-2008 |
| 106310310 | Natural wax containing (e.g., carnauba, montan, Japan, candelilla, etc.) | 1 |
| 20140338563 | Solid Or Phase Change Inks With Improved Properties - A solid or phase change inkjet ink incorporating a polar acidic wax is described. The use of polar waxes as an ink additive improves the polarity of the ink and adhesion of the ink to paper. A method for applying the solid or phase change ink incorporating an acidic polar wax additive to form an image is also described. | 11-20-2014 |
