    Abstract: The present invention discloses substituted phenyl di and trisazo dyes free of reactive groups having two or three sulfonic acid groups, of the general formula: (I) wherein D1 is Z is hydrogen or D4-N=N-; D2 is phenyl substituted by hydroxyl, hydroxysulfonyl, chlorine or nitro, or is naphthyl substituted by hydroxy, hydroxysulfonyl or nitro, X, independently of one another, are hydroxyl or amino, D3 is phenyl which is substituted by hydroxysulfonyl, chlorine, bromine, methyl, methoxy, ethoxy, nitro, phenylamino, sulfophenylamino or nitrosulfophenylamino, or is naphthyl which is substituted by hydroxysulfonyl; D4 is phenyl which is unsubstituted or substituted by methyl, ethyl, methoxy, ethoxy, chlorine, bromine, nitro, sulfamoyl or hydroxysulfonyl, or is naphthyl which is substituted by hydroxysulfonyl; and R2 is methyl, ethyl or allyl; the rings B and E may additionally be substituted by methyl, ethyl, methoxy, ethoxy, chlorine, bromine or hydroxysulfonyl, with the proviso that D2 has a hydroxyl group ortho to the azo bond; or the iron, manganese, cobalt, chromium, nickel or copper complexes of this dye. These compounds, particularly in the form of their metal complexes are suitable for dyeing nitrogen-containing fibers such as wool, and preferably, leather. The present dyes yield very fast brown hues, in particular on retanned leather.

    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.
