Patent application number | Description | Published |
20080219915 | Carbon black, method of producing carbon black, and device for implementing the method - The invention relates to a carbon black having an aggregate size distribution which has a (d | 09-11-2008 |
20090035210 | CARBON BLACK - Carbon black with an OAN, measured on the beaded carbon black, of less than 120 ml/100 g. A process for the preparation of the carbon black is described, wherein a salt solution is converted into an aerosol and this is then introduced into the carbon black formation zone. The carbon black can be used in inks, paints, lacquers, printing inks and ink-jet inks, and for coloring plastics. | 02-05-2009 |
20090305011 | Ink Jet Ink - Ink jet inks comprising a modified pigment, wherein the modified pigment is a pigment having attached organic groups of substituted or unsubstituted 1,2-benzenedicarboxylic acids and/or salts thereof. | 12-10-2009 |
20100147187 | Ink Jet Ink - Ink jet ink containing at least one pigment and at least one oxidized carbon black. | 06-17-2010 |
20100179270 | LAMP BLACK - The invention relates to lamp blacks having a DBP value of less than 100 ml/100 g. The invention also relates to a method for producing said lamp black, wherein lamp black is mechanically size-reduced in a rotary ball mill. The lamp blacks according to the invention can be used in carbon black dispersions, paint systems, printing inks, plastic mixtures and rubber mixtures. | 07-15-2010 |
