    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.

    Azo dyes contg. benzisothiazole di:sulphonic acid gp. - give fast red to green-blue tints on polyamide(s), pelts etc.

    Abstract: Acid azo dyes are claimed having the formula (I) in the free acid form, in which K is the residue of a coupling component. Typical coupling components K are in which R1 is H, Me, OMe or OEt; R2 is H, Cl, Me, Et, benzyl, sulphobenzyl, OMe, OEt. NHCO-C1-4 alkyl, acylamino or SO3H; R3 is H, 1-4C alkyl, 2-3C hydroxy- or dihydroxyalkyl, beta-sulphoethyl, gamma-sulphopropyl, beta-cyanoethyl, beta-hydroxy-gamma-chloropropyl, 1-4C alkoxyethyl, acetoxyethyl, beta-chloroethyl, gamma-amino or gamma-acetylaminopropyl, beta-carboxyethyl, beta-carbamoylethyl, benzyl, sulphobenzyl, phenylethyl, sulphophenylethyl or cyclohexyl; R4 is 1-4C alkyl, 2-3C hydroxyalkyl, beta-cyanoethyl, beta-chloroethyl, 1-4C alkoxyethyl, benzyl or sulphobenzyl; R5 is amino, acetylamino, chloracetylamino, phenoxyacetylamino, benzoylamino, chlorbenzoylamino or dichlorbenzoylamino; R6 is (chloro)methyl, phenyl, chlorophenyl or acetylamino; R7 is 1-8C alkyl, 2-3C hydroxyalkyl, phenyl-1-4C alkyl, cyclohexyl or phenyl; R8 is H or 1-3C alkyl; R9 is H, 1-4C alkyl, 1-4C alkoxy, 2-3C alkyl or hydroxyethyl or -propyl; R10 is (cyclo)alkyl or aryl or one R10 may be H; R11 is H, 1-4C alkoxy, benzyloxy or phenoxy-substd. 1-4C alkyl; X is CN or carbomoyl. (I) are red to green-blue dyes which are esp. useful for dyeing natural and synthetic polyamides, wool, pelts etc. The dyes have very high colour strength and give dyeings with very good resistance to light, moisture, sweat, seawater etc.
