    Abstract: Compounds containing sulfonic acid groups and of the general formula I I where D1 is a radical of a diazo component, X1 and X2 independently of one another are each hydroxyl or unsubstituted or substituted amino, Y is hydrogen, chlorine, methyl, hydroxysulfonyl or a radical of the formula D3-N=N- and D2 is a radical of the formula +TR D3 is a radical of a diazo component from the aniline or aminonaphthalene series, K is a radical of a coupling component from the benzene or naphthalene series, and the rings in the coupling component D2 may furthermore be substituted by chlorine, methyl, methoxy, hydroxysulfonyl, aminosulfonyl, hydroxyl or acylamino, and metal complexes of such compounds, give very fast, brown dyeings, particularly on leather.

    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: Acid azo dyes containing thiazole coupling components, of the general formula I where D is the radical of a diazo component, R is hydrogen, acetyl, benzoyl or an aliphatic, cycloaliphatic, aromatic or heterocyclic radical, R1 and R2 independently of one another are optionally substituted alkyl, cycloalkyl, aralkyl or aryl, R1 may also be hydrogen and R1 and R2 together with the nitrogen may be a heterocyclic radical, and the radicals D, R, R1 and/or R2 may in total contain from 1 to 4 -SO3H groups. The deeply colored novel compounds are particularly suitable for dyeing polyamides, and the dyeings obtained have very good lightfastness and wetfastness.
