Abstract: Carbon material having organic groups, obtainable by the reaction of carbon material with organic compounds of the general formula 1 The invention's carbon materials having organic groups are useful in dispersions, rubber, plastics, inks, including solventborne inks, waterborne inks, inkjet inks, xerographic toners, coatings, paints, bitumen, concrete or other building materials, paper or as a reducing agent in metallurgy.

Abstract: The invention is directed to a suspension containing: (a) at least one water-insoluble colorant, (b) at least one heterocyclic compound of the general formula 1 and (c) water and/or a mono- or polyhydric alcohol. The aqueous suspension is produced when the water-insoluble colorant and the heterocyclic compound of the formula 1 are dispersed in water and/or a mono- or polyhydric alcohol. The suspension is useful for producing waterborne inks, ink jet inks, coatings and solventborne printing inks.

Abstract: Aqueous, colloidal gas black suspension containing (a) a gas black, (b) an azo compound of the general formula 1. (C) and water. The aqueous, colloidal gas black suspension is produced by dispersing the gas black and the azo compound of the general formula 1 in water. It can be used in the production of inks, ink-jet inks, surface coatings and coloured printing inks.

Abstract: Aqueous, colloidal gas black suspension aqueous, colloidal gas black suspensions, containing a gas black, an azo compound of formula 1, and water. The aqueous, colloidal gas black suspensions are produced by dispersing the gas black and the azo compound of formula 1 in water. The aqueous, colloidal gas black suspension can be used to produce inks, ink jet inks, paints, printing inks, latices, textiles, leather, adhesives, silicones, plastics materials, concrete and construction materials.

Abstract: Aqueous, colloidal, freeze-resistant and storage-stable gas black suspension are disclosed containing 2-30 wt. % gas black, 0-40 wt. % carbon black, a dispersion-supporting additive, a biocide and water and having a zeta potential of less than −10 mV, a surface tension of greater than 50 mN/m and an average particle size of less than 200 nm. The aqueous, colloidal, freeze-resistant and storage-stable gas black suspension is produced by dispersing the gas black and the carbon black in water together with the dispersion-supporting additive and biocide. Inks, ink-jet inks, lacquers and printing inks can be made from these suspensions.

Abstract: The inkjet ink contains at least one pigment and at least one compound having a mean particle size of greater than 50 nm from the group comprising pyrogenic silicic acid, hydrophobised pyrogenic silicic acid, pyrogenic mixed oxides or pyrogenic aluminium oxides.
