| 摘要 |
By reaction of 1,4-diaminobenzene-2,5-disulphonic acid with a 2,4,6-trihalo-1,3,5-triazine, preferably trichlorotriazine, a primary condensation product is obtained which is reacted with amino group-containing dyestuffs of the anthraquinone, phthalocyanine or monoazo series to give a bisreactive dyestuff of the general formula 1 <IMAGE> where the substituents D1, D2, R1, R2, X1 and X2 have the meaning given in Patent Claim 1. The novel reactive dyestuffs are distinguished by high reactivity, high fixation, good exhaust properties, good washability of the non-fixed portions and useful fast green shades.
