<p>Mixtures of water-soluble, fiber-reactive, yellow dyestuffs which exhibit superior build-up and colour properties over those properties obtained with the individual components of the mixtures, the dyestuffs conforming to the general formula <CHEM> wherein R is each independently selected from alkyl of 1 to 4 carbon atoms and alkoxy of 1 to 4 carbon atoms and hydrogen, with the proviso that at least one of said R moieties is selected from alkyl of 1 to 4 carbon atoms in at least one of said both dyestuffs and that each of said both dyestuffs contains at least two R moieties selected from alkoxy of 1 to 4 carbon atoms, X is vinyl or is a group of the general formula -CH2-CH2-Z, in which Z is chlorine, bromine, sulfato, thiosulfato, phosphato or alkylamino with an alkyl of 1 to 4 carbon atoms, or dialkyl-amino with alkyls each having independently 1 to 4 carbon atoms, and M is hydrogen or an alkali metal.</p> |
