Abstract: A reactive dye of formula wherein M is hydrogen, an alkali metal or one equivalent of an alkaline earth metal, Z1 is vinyl, ?-sulfatoethyl or the radical —NHCO—(CH2)3—SO2—CH2CH2Cl; R1 denotes H or sulfo; and R2 is H, methyl, methoxy or sulfo, n is the number 3; Y is vinyl or a radical —CH2—CH2-U and U is —Cl or —OSO3H, is suitable for dyeing and printing cellulosic or amide-group-containing fibre materials.

Abstract: The present invention relates to azo dyes of formula (1), wherein D is a radical of formula (2) or (3), R1 and R2 independently denote hydrogen; C6-C10 aryl which is unsubstituted or substituted by cyano, carboxy, hydroxy, halogen, C1-C6alkyl, or C1-C6alkoxy; C1-C12alkyl which may be interrupted one or more times by —O—, —S—, —NR4—, —CO—, —COO— or —OOC—, and is unsubstituted or substituted by cyano, carboxy, hydroxy, C6-C10 aryl, or C6-C10 aryloxy, which C6-C10 aryl or C6-C10 aryloxy is unsubstituted or substituted by cyano, carboxy, hydroxy, halogen, C1-C6alkyl, or C1-C6alkoxy; R3 and R4 are each independently of the other hydrogen, halogen, nitro, cyano, trifluoromethyl, carboxy, C1-C6alkyl, C1-C6alkoxy, C1-C6alkylcarbonyl, C6-C10 arylcarbonyl, C1-C6alkoxycarbonyl, C1-C6alkylsulfonyl, C1-C6alkylsulfonylamino or C1-C4 alkanoylamino; and R5 is halogen, nitro, cyano, trifluoromethyl, carboxy, C1-C6alkyl, C1-C6alkoxy, C1-C6alkylcarbonyl, C6-C10 arylcarbonyl, C1-C6alkoxycarbonyl, C1-C6alkylsulfonyl, C1-C6alkylsu

Abstract: A compound of formula wherein V, W, X and Y represent N or CH, at least one of V, W, X and Y being N and at least two of V, W, X and Y being CH; and R1, R2 and R3 are each independently of the other hydrogen, C1-C8alkyl, C1-C8alkoxy, nitro, cyano, trifluoromethyl, halogen or hydroxy; with the proviso that the compounds of formulae are excluded, provides good lightfastness properties to textile fibre materials, in particular PES fibre materials.
