Black perylene pigments which comprise one of the isomers of the formula Ia or Ib in which

Black perylene pigments

Aqueous dye preparations useful for producing inks for the inkjet process or writing inks or for producing aqueous alcoholic coating or printing colors comprise, based on the weight of the preparation, from 0.1 to 15% by weight of a dye quantity comprising from 90 to 100% by weight of the dye of the formula I ##STR1## where Kat.sup..sym. is the equivalent of a metal or ammonium ion, from 1 to 40% by weight of carbon black and from 0.1 to 15% by weight of polyethylene glycol.

Aqueous dye preparations

Ballpoint pen pastes comprising at least one phthalocyanine pigment and customary ballpoint pen paste resin and organic solvent as essential components and also, if desired, further customary additives, and the preparation thereof.

Ballpoint pen pastes with phthalocyanine pigments

Detection of naphthylamines in mineral oils

A liquid useful as printing ink contains one or more dyes with their absorption maximum within the range from 700 to 1200 nm selected from the phthalocyanines, the naphthalocyanines, the nickel-dithiolene complexes, the aminium compounds of aromatic amines, the methine dyes or the azulenesquaric acid dyes, as well as solvent and binder.

Use of a liquid containing IR dyes as printing ink

Solid pigment formulations containing from 70 to 97% by weight, based on the total weight of the formulation, of one or more pigments and also from 3 to 30% by weight, based on the total weight of the formulation, of at least one surfactant which is an adduct of ethylene oxide and optionally propylene oxide with ethylenediamine, the proportion of ethylene oxide being from 46 to 100% by weight, based on the total weight of ethylene oxide and propylene oxide in the adduct, and the adduct having an average molecular weight of from 5000 to 40,000, are useful for pigmenting printing ink and gloss paint compositions.

Highly concentrated solid pigment formulations

Aminoazo compounds of the general formula ##STR1## where A is the radical of a diazo component or coupling component,

Aminoazo compounds

Compounds of the formula ##STR1## in which K is ##STR2## Ar.sup.1 is phenyl; phenyl substituted by chlorine, methoxy, ethoxy, methyl, acetylamino or benzoylamino; or ##STR3## Ar.sup.2 is phenyl; or phenyl substituted by chlorine, methyl or sulfamoyl,

Azo dyes from an oxadiazolyl-substituted aniline

An azo dye of the general formula ##STR1## where A is cyano or carbamoyl,

Azo dyes of the 2,6-di(substituted) amino pyridine series

Dyes of the formula I ##STR1## in which A is phenyl or phenyl substituted by chloro, bromo, nitro, methyl, ethyl, methoxy or ethoxy; B.sup.1 is hydrogen, chloro, bromo, nitro, methyl or trifluoromethyl; B.sup.2 is hydrogen, chloro, bromo or nitro; R is C.sub.1 to C.sub.4 alkyl; and X is hydrogen, chloro or bromo. The compounds are distinguished by high color strength, brilliance and good fastness properties such as light-fastness, fastness to overspraying, plasticizers fastness and insolubility in most solvents used in connection with pigments. They are particularly suitable for the coloring of air-drying surface coatings, rigid polyvinyl chloride and emulsion paints.

Azo dyes having an oxdiazolyl-1,2,4 group

Compounds which in the form of the free acids have the formula I ##STR1## where K is the radical of a coupling component, n is 1, 2 or 3, R.sup.1 is hydrogen, chlorine, bromine or hydroxysulfonyl, R.sup.2 is hydrogen, chlorine, bromine, nitro, methyl or trifluoromethyl and R.sup.3 is hydrogen, alkyl of 1 to 8 carbon atoms (which may or may not be interrupted by oxygen and may be unsubstituted or substituted by hydroxyl, alkoxy of 1 to 8 carbon atoms, phenyl or phenoxy), benzyl, phenylethyl, cyclohexyl, phenyl (which may be unsubstituted or substituted by chlorine, bromine, nitro, methyl, ethyl, methoxy, ethoxy, phenoxy, dialkylamino, where alkyl is of 1 to 4 carbon atoms, or hydroxysulfonyl), naphthyl, pyridyl, thienyl or furyl. The compounds of the formula I may be used for dyeing nitrogen-containing fibers; the dyeings obtained are very fast and have brilliant hues.

Azo dyes containing sulfonic acid groups and oxdiazolyl radicals

Azo dyes which in the form of the free bases correspond to the general formula ##STR1## where R.sup.1 is hydrogen, chlorine, bromine, methyl, trifluoromethyl, methoxy, nitro or a radical X, R.sup.2 is hydrogen, chlorine or nitro, R.sup.3 is hydrogen, chlorine, bromine, methyl, methoxy, nitro or a radical X, R.sup.4 is hydrogen or alkyl of 1 to 3 carbon atoms, R.sup.5 is cyano, carbamoyl or acetyl, R.sup.6 is hydrogen, substituted or unsubstituted alkyl or cycloalkyl or a radical X and X is a radical containing an amino group, the molecule containing at least one radical X. The compounds of the formula I are exceptionally useful for improving the flow of pigment-containing printing inks.
