1. A metal-free or metalliferous azo dye of the formula II which is devoid of sulfonic acid groups (X - N = N - Y - N = N - X)-(CH2 - NH - CO - W - Q)n in which each of the symbols X independently of the other is a coupling component of the formula see diagramm : EP0057159,P27,F1 see diagramm : EP0057159,P27,F2 see diagramm : EP0057159,P27,F3 see diagramm : EP0057159,P27,F4 see diagramm : EP0057159,P27,F5 see diagramm : EP0057159,P27,F6 or see diagramm : EP0057159,P27,F7 in which formulae R1 is hydrogen or a radical of the formula see diagramm : EP0057159,P27,F8 or see diagramm : EP0057159,P27,F9 R2 , R3 and R4 are hydrogen, C1 -C4 alkyl, C1 -C4 alkoxy, phenoxy, halogen, CN, NO2 or a heterocyclic radical and R5 is hydrogen, phenyl, or C1 -C4 alkyl which is unsubstituted or substituted by hydroxy or phenyl ; and Y is a divalent bridge member of the formula see diagramm : EP0057159,P27,F10 see diagramm : EP0057159,P27,F11 (where M is N, S, O or CH2 ) [H, C1 -C4 alkyl or C1 -C4 alkylcarbonyl] see diagramm : EP0057159,P27,F12 oder see diagramm : EP0057159,P27,F13 in which the phenyl radicals A to E can be monosubstituted or polysubstituted by C1 -C4 alkyl, C1 -C4 alkoxy, phenoxy, CN, halogen, nitro, OH or COOH, the number of carboxyl groups being less than n, and Z is a direct bond or a divalent radical, W is an alkylene group having 1 to 3 carbon atoms or a group of the formula - NH(CH2 )1-3 - and Q is a basic or quaternised amino radical of the formula see diagramm : EP0057159,P28,F1 see diagramm : EP0057159,P28,F2 see diagramm : EP0057159,P28,F3 or see diagramm : EP0057159,P28,F4 in which each of R'1 to R'4 independently is a C1 -C4 alkyl radical which is unsubstituted or substituted by a hydroxyl group, each of R'5 and R'6 independently is a C1 -C4 alkyl radical, R'7 is hydrogen, C1 -C4 alkyl which is unsubstituted or substituted by hydroxy, or is cyclohexyl which is unsubstituted or substituted by 1 to 3 methyl groups, or is a phenyl radical and R'8 is C1 -C4 alkyl which is unsubstituted or substituted by hydroxy, or the radicals R'1 and R'2 , or the radicals R'3 and R'4 , or the radicals R'7 and R'8 , together with the common N atom, form a pyrrolidine, piperidine, morpholine or piperazine ring, or the radicals R'3 , R'4 and R'5 , together with the common N atom, form a pyridinium ring or a 1,4-diazabicyclo[2.2.2]octane radical, and n is a number from 1 to 4, or, of Q is a quaternary amino group, an inorganic or organic salt thereof. |
