    Abstract: Colourant mixtures containing isoquinolineazo pigments of the formula I where X is chlorine, bromine, C1-C4-alkoxy or nitro, n is 1, 2 or 3, and the ring A may be substituted, and isoquinolineazo dyes of the formula II where Y is C6-C20-alkoxy which may be interrupted by one or more oxygen atoms, and the ring B may be substituted. Also described are novel isoquinolineazo dyes of the abovementioned formula II.

    Abstract: An isothiazolylazo dye of the formula I wherein R is an alkyl group or unsubstituted aryl or substituted aryl group selected from the group consisting of +TR and K is a radical of the formula +TR where B is C1-C4 alkyl or a substituted amino radical selected from the group consisting of R1 is hydrogen, methyl, methoxy or ethoxy, R2 and R3 independently of one another are each unsubstituted C1-C4 alkyl or substituted alkyl groups selected from the group of C1-C4 alkyls which are substituted by chlorine, bromine, cyano, hydroxyl, C1-C4-alkoxy, benzyloxy, phenoxy, phenyl, C1-C4-alkylcarbonyloxy which is unsubstituted or substituted by C1-C4-alkoxy, phenoxy or phenyl, phenycarbonyloxy which is unsubstituted or substituted by chlorine, bromine, methoxy, ethoxy, methyl or ethyl, oxycarbonyl, C1-C4-alkoxycarbonyl, C1-C4-alkoxycarbonyloxy, carbamyl, phenalkyloxycarbonyloxy, phenoxyalkyloxycarbonyloxy, C1-C4-alkoxyalkoxycarbonyloxy, phenylaminocarbonyloxy which is unsubstituted or substituted by chlorine, methoxy or methyl, C1-C4-alkoxyalkoxycarbonyl, phenylalkyloxycarbonyl or C1-C4-alkylaminocarbonyloxy which is unsubstituted or substituted by C1-C4-alkyl, C1-C4-alkoxy, chlorine or bromine; or R3 is hydrogen, R4 is a radical of the formula -A-OCO-Y-R, Z is hydrogen or methyl, X is hydrogen, methyl, methoxy, chlorine or an acylamino radical selected from the group consisting of NHCHO, NHCOCH3, NHCOC2H5, NHCOaryl, NHCOCH2aryl, A is C2- or C3-alkylene and Y is -O- or -NH-. The dyes are very useful for dyeing cellulose esters and synthetic polyesters; the dyeings obtained are from yellow to blue, and very fast.

    Abstract: An electrostatic toner contains a polymeric binder and as a charge stabilizer a polyamine whose average molecular weight is from 150 to 15,000 and wherein the nitrogen atoms are separated from each other by C1-C13- alkylene, which may be phenyl-substituted, or by phenylene, which may be C1-C4-alkyl-substituted, and are substituted by C1-C13-alkyl, which may be phenyl-, hydroxyl- or carboxyl-substituted, phenyl, C1-C10-alkanoyl, benzoyl, C1- C6- alkylcarbamoyl, phenylcarbamoyl or a radical of the formula CO-L-CO, where L is C2-C8-alkylene, the last case resulting in the crosslinking of two polyamine units.

    Abstract: The invention relates to a process for tanning leather by using compounds of the general formula I where m is 0 or 1 and the radicals R are independently of each other C1-C18-alkyl, which may be substituted by hydroxyl or carboxyl and/or interrupted by oxygen atoms, or else one of the radicals R is a radical of the formula where R is alkylene, which may be substituted by hydroxyl and/or interrupted by oxygen atoms.
