Fiber-reactive dyestuffs, such as, for example, azo dyestuffs and heavy metal complex derivatives thereof, anthraquinone dyestuffs, phthalocyanine dyestuffs and formazan dyestuffs, which contain a fiber-reactive group of the vinylsulfone series and furthermore a group of the general formula ##STR1## in which R.sup.x is hydrogen or lower alkyl, which can be substituted by substituents customary in dyestuffs, and Q.sup.1 and Q.sup.2 both independently of one another are each lower alkyl, which is substituted by 1 or 2 lower alkanoyl groups or 1 or 2 lower alkoxycarbonyl groups or by one such alkoxycarbonyl and alkanoyl group, or an amino group, which is substituted by optionally substituted aryl and/or alkyl radicals, or an optionally substituted alkoxy, aryloxy, alkylthio or arylthio radical or a cyanamido radical, are described. The novel dyestuffs dye material containing hydroxy and/or carboxamide groups, such as cellulose fiber materials, wool and polyamides, in deep shades, and moreover are suitable for discharge and resist printing.
含有纤维反应性基团的染料,例如偶氮染料和重金属络合物衍生物、蒽醌染料、酞菁染料和甲基酰胺染料,其中包含乙烯磺酮系列的纤维反应性基团,另外还包含一般式##STR1##中的基团,其中R.sup.x为氢或较低的烷基,可以被染料中常见的取代基取代,而且Q.sup.1和Q.sup.2彼此独立地均为较低的烷基,可以被1或2个较低烷酰基或1或2个较低烷氧羰基基团或一个这样的烷氧羰基和烷酰基基团取代,或者是一个氨基,可以被可选择地取代的芳基和/或烷基基团取代,或者是一个可选择地取代的烷氧基、芳氧基、烷硫基或芳硫基基团或氰胺基团,这些都被描述。这种新型染料染料材料含有羟基和/或羧酰胺基团,例如纤维素纤维材料、羊毛和聚酰胺,颜色深沉,而且适用于印花和阻隔印花。
