    摘要: Improved reactive dyestuffs of the following formula (I) ##STR1## in which the substituents have the meaning given in the description. The improved reactive dyestuffs are highly suitable for the dyeing and printing of natural or synthetic OH-- and/or amido-containing materials, in particular, those made of cellulose and polyamides.
