20080292533 | Low structure carbon black and method of making same - A carbon black having an I | 11-27-2008 |
20080305422 | Carbon blacks, toners, and composites and methods of making same - A chemical toner is described as well as methods of preparing the same. | 12-11-2008 |
20090208751 | Mesoporous carbon black and processes for making same - The invention is directed to processes for increasing the surface area of a carbon black starting material and for forming mesoporous carbon black. The process includes the step of contacting a carbon black starting material having a first BET nitrogen surface area with an oxidant in a fluidized bed under conditions effective to form a carbon black product having a second BET nitrogen surface area greater than the first BET nitrogen surface area. The invention is also directed to carbon black product formed by this process. | 08-20-2009 |
20100099040 | Toners comprising modified pigments and processes for preparing the same - The present invention relates to toner compositions comprising a resin and a colorant. Various embodiments of the colorant used in the toner compositions are disclosed, including a modified pigment comprising a pigment having attached at least one organic group having the formula −X-I, wherein X, which is directly attached to the pigment, represents an arylene or heteroarylene group, or an alkylene group, and I represents a non-polymeric group comprising at least one ionic group or at least one ionizable group. Processes for preparing toner compositions are also described. | 04-22-2010 |
20100167195 | Carbon blacks, toners, and composites and methods of making same - A chemical toner is described as well as methods of preparing the same. | 07-01-2010 |
20110009551 | HIGH RESISTIVITY COMPOSITIONS - The present invention relates to a black matrix formed by applying a curable coating composition onto a substrate to form a curable coating, curing the curable coating imagewise to form a coating, and developing and drying the coating. The curable coating composition comprises a vehicle, a curable resin, and at least one modified pigment comprising a pigment having attached at least one organic group having the formula —X—I or —X—NI, wherein X, which is directly attached to the pigment, represents an arylene or heteroarylene group, an alkylene group, an aralkylene group, or an alkarylene group, I represents a non-polymeric group comprising at least one ionic group or at least one ionizable group, and NI represents a non-polymeric group comprising at least one nonionic group. The curable coating composition, curable coating, and cured coating are also described. Also disclosed is a method of controlling the resistivity of a coating. | 01-13-2011 |
