Claims9
Dyestuff mixture consisting essentially of at least two reactive dyestuffs, characterised in that it comprises at least one dyestuff having a dichloroquinoxaline reactive radical, of the formula ##STR10## wherein A denotes six-membered carbocyclic,
- X denotes hydrogen,
- Z denotes hydrogen or an alkyl group,
- R denotes the radical of a diazo component of the benzene or naphthalene series,
- R.sub.1 denotes the radical of an azo component,
- m denotes 1,
- and a chlorotriazine dyestuff of the general formula (II) ##STR11## wherein R.sub.2 independently of one another denotes H or C.sub.1 -C.sub.4 -alkyl,
- D.sub.1 and D.sub.2 denote components having the structure ##STR12## where R.sub.3 =CH.sub.3 or C.sub.2 H.sub.5,
- R.sub.4 =COOH or CONH.sub.2,
- R.sub.5 =CH.sub.3,
- R.sub.7 =CH.sub.3 or COOH,
- R.sub.8 =H or SO.sub.3 H and
- R.sub.9 =H, Cl or CH.sub.3,
- A.sub.1 and A.sub.2 independently of one another denote ##STR13## where R.sub.6 =CH.sub.3, C.sub.2 H.sub.5, NHCO--NH.sub.2 or NH--CO--CH.sub.3, and
- B denotes ##STR14## where L=a single bond, NH--CO--NH or --CH.dbd.CH--.
