Abstract: Useful for the ink jet process are dye preparations which contain from 0.01 to 10% by weight, based on the weight of the preparation, of a dye quantity which is from 90 to 100% by weight the dye of the formula I where Kat(+) is the equivalent of a metal or ammonium ion, from 0 to 15% by weight, based on the weight of the preparation, of one or more water-miscible organic solvents, and from 75 to 99.99% by weight, based on the weight of preparation, of water and which are essentially free of foreign salts, in the ink jet process.

Abstract: The invention concerns the use, as markers for hydrocarbons, of leucotriarylmethanes of formula (I) in which Z is an aromatic carbocyclic or heterocyclic group and R , R , R and R are hydrogen, optionally substituted C1-C16 alkyl, optionally substituted phenyl or optionally substituted naphthyl. The invention also concerns hydrocarbons containing such leucotriarylmethanes and a method of detecting leucotriarylmethanes in hydrocarbons.

Abstract: Method for detecting marked mineral oils by treating the marked mineral oil with an extractant comprising water, a solvent and a base comprises using as marker an azo dye of the formula where ring A may be benzofused, m is from 1 to 4, X1 is hydrogen, C1-C4-alkyl, cyano or nitro, X2 is hydrogen, C1-C4-alkyl, cyano, nitro, C1-C4-alkoxy or C1-C16-alkoxycarbonyl, X3 is hydrogen, C1-C4-alkyl, cyano or C1-C16-alkoxycarbonyl, and X4 is hydrogen, hydroxyl, substituted or unsubstituted C1-C8-alkyl, C1-C4-alkoxy, amino, C1-C4-dialkylamino or substituted or unsubstituted C1-C16-monoalkylamino, as solvent a partially or completely water-miscible organic solvent, and as base an alkali or alkaline earth metal hydroxide, an alkali metal carbonate or a quaternary ammonium hydroxide, the use of azo dyes as markers for mineral oils, and novel azo dyes.

Abstract: Electrostatic toner containing a polymeric binder and, as the charge stabiliser, a 1:2 chromium, iron, cobalt or zirconium complex of azo colorants of the formula: D-N=N-K, where D is derived from a diazo component D-NH2, which arises from the group consisting of 2-amino-4-nitrophenol, anthranilic acid and picramic acid, and K is derived from coupling components K-H which arise from the group consisting of beta -naphthol, diacetic acid anilide and 1-phenyl-3-methyl pyrazol-5-one, and the use of the aforementioned metal complexes as charge stabilisers in electrostatic toners.
