    Abstract: Compounds which in the form of the free acid are of the general formula I I where A is a radical of the formula the radicals Y independently of one another are each hydroxyl or amino, X is hydrogen, hydroxysulfonyl or a radical of the formula D-N=N-, R is a radical of 1-aminonaphthalene-4-, -5-, -6-, -7-or -8-monosulfonic acid or of 1-aminonaphthalene-3-6,-, -3,7-, -3,8-, -4,7- or -4,8-disulfonic acid, or a Cu, Fe, Ni, Co, Mn or Cr complex thereof, and D is phenyl which is unsubstituted or substituted by methyl, methoxy,ethoxy, nitro, chlorine, bromine or sulfo, or is sulfo-substituted naphthyl. These compounds are preferably used for dyeing leather.

    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.
