Process for preparing reactive azo dyes |
| abstract |
Reactive dyestuffs of the formula (I) (I), <IMG> wherein A denotes the radical of a diazo component and X is a fibre-reactive heterocyclic radical are obtained by hydrolysis of maleylated azo dyestuffs of the formula (IV) (IV), <IMG> and subsequent reaction with reactive components of the formula X-Hal without intermediate isolation, the other substituents having the meaning given in the description. |
