##STR1## wherein A is 2-thiazolyl, 4-nitro-2-thiazolyl, 2-benzothiazolyl, 6-methoxy-2-benzothiazolyl, 6-ethoxy-2-benzothiazolyl, 6-chloro-2-benzothiazolyl, 5,6-dichloro-2-benzothiazolyl, 4-bromo-6-chloro-2-benzothiazolyl, 4,6-dibromo-2-benzothiazolyl, 4-bromo-6-methoxy-2-benzothiazolyl, 4-bromo-6-ethoxy-2-benzothiazolyl, 4-bromo-5,6-dichloro-2-benzothiazolyl, 6-methylsulfonyl-2-benzothiazolyl, 4-bromo-6-methylsulfonyl-2-benzothiazolyl, or 6-hydroxyethylsulfonyl-2-benzothiazolyl, X is hydrogen, chlorine, methyl or trifluoromethyl, R is alkyl containing 1 to 4 carbon atoms, U is alkylene containing 1 to 5 carbon atoms, and y is hydrogen, chlorine or methyl. The dyestuffs are useful for the dyeing and printing of polyamide fibers for which they have a good affinity for polyamides so that the tinctorial yield is excellent and the exhaustion of the dyestuffs is very good. The colorations obtained have a remarkable brilliance, good fastness to washing and to light and finally good covering of bars i.e. absence of streakiness.
其中A为2-噻唑基、4-硝基-2-噻唑基、2-苯并噻唑基、6-甲氧基-2-苯并噻唑基、6-乙氧基-2-苯并噻唑基、6-氯基-2-苯并噻唑基、5,6-二氯基-2-苯并噻唑基、4-溴-6-氯基-2-苯并噻唑基、4,6-二溴基-2-苯并噻唑基、4-溴-6-甲氧基-2-苯并噻唑基、4-溴-6-乙氧基-2-苯并噻唑基、4-溴-5,6-二氯基-2-苯并噻唑基、6-甲基磺酰基-2-苯并噻唑基、4-溴-6-甲基磺酰基-2-苯并噻唑基或6-羟乙基磺酰基-2-苯并噻唑基,X为氢、氯、甲基或三氟甲基,R为含有1至4个碳原子的烷基,U为含有1至5个碳原子的烷烃,y为氢、氯或甲基。这些染料对聚酰胺纤维的染色和印花非常有用,它们与聚酰胺有很好的亲和性,因此染料的着色效果优秀,染料的耗尽非常好。所得到的色彩具有卓越的光泽度,良好的耐洗涤和耐光度,最终具有良好的遮盖性,即没有条纹。
