Dyestuffs of the formula <IMAGE> WHEREIN (R)n represents n substituents R each of which may be independently halogen, lower alkyl, lower alkoxy or COOH R1 is H, optionally substituted lower alkyl, optionally substituted aryl or optionally substituted aralkyl, N IS 0-3, (A+B) IS 0-4, X is O, S or NR2, where R2 is H or optionally substituted lower alkyl, Y is an optionally substituted aliphatic or optionally substituted araliphatic linking group, and EACH Z is independently a H or a cellulose-reactive group, and when (a+b) is O there is at least one SO3H group as substituent on the groups R1, X or Y. |
