<p>Reactive dyestuffs in tautomeric forms for polyamide and cellulose textiles. N2A. Water-sol. azo dyes which contain at least one sulphonic acid grp., at least one cellulose reactive grp. and at least one grp. of formula: (Z = H or opt. substd. alkyl, aralkyl, cycloalkyl, aryl or heterocyclic residue, T1 = H CN, COOR1, CONR1R2, COR1 or OH grp. of an opt. substd. alkyl, aralkyl, cycloalkyl, aryl or heterocyclic residue, and R1 and R2 each = H, an opt. substd. aralkyl, alkyl, cycloalkyl, aryl or heterocyclic residue, or the gp., -NR1R2 grp. or an opt. substd. alkyl, aralkyl, cycloalkyl, aryl or heterocyclic residue and M = H) are prepd. by diazotising an aromatic amine and coupling the resulting diazo cpd. with a coupling component consisting of one of the possible tautomeric forms of formula: The amine and the coupling component together contain at least one fibre reactive grp. and at least one sulphonic acid grp.</p> |
