Reactive bisazo dyes of the general formula (I)
are described,
wherein X, and X2 are each a hydrogen atom, a methyl or methoxy group, a chlorine atom, or a carboxylic acid or sulfonic acid group, Y is a hydrogen atom, a methyl or sulfonic acid group, Z is -CH2CH2OSO3H, -CH2CH2OPO3H2, -CH2CH2CI or -CH =CH2, and Z1, Z2 and Z3 are each a hydrogen or chlorine atom, a methyl, methoxy, sulfonic acid or carboxylic acid group. These dyes are useful for dyeing celful- ose fibers and cellulosic textile goods in deep blue colors with good fastnesses, particularly, chlorine, light and perspiration-light fastnesses, high acid stability, good white dischargeability as well as good levelling properties.
通式 (I) 的活性偶氮染料
所述、
其中 X 和 X2 各为氢原子、甲基或甲氧基、氯原子或羧酸或磺酸基团;Y 为氢原子、甲基或磺酸基团;Z 为 -CH2CH2OSO3H、-CH2CH2OPO3H2、-CH2CH2CI 或 -CH =CH2;Z1、Z2 和 Z3 各为氢原子或氯原子、甲基、甲氧基、磺酸或羧酸基团。这些染料可用于染制具有良好牢度(尤其是耐氯牢度、耐光牢度和耐汗渍牢度)、高酸稳定性、良好的放白性以及良好的匀染性的深蓝色纤维和纤维素纺织品。
