An asymmetric dioxazine compound represented by the following formula (I) in the free acid form:
wherein A₁ and A₂ independently of one another are each sulfo, halo, alkyl or alkoxy, W is an unsubstituted or substituted aliphatic or aromatic bridging group, X₁ and X₂ independently of one another are each hydrogen, halo, alkyl, alkoxy or phenoxy, R₁ and R₂ independently of one another are each hydrogen or unsubstituted or substituted alkyl, R₃ and R₄ independently of one another are each hydrogen, halo, alkyl, alkoxy or unsubstituted or substituted amino, Z is a fiber-reactive group, m and n independently of one another are each 0 or 1, provided that m≠n, and ℓ is 1 or 2. This compound is suitable for dyeing and printing cellulose fiber, natural and synthetic polyamide fibers, polyrethane fiber, leather and the like and mixed yarns thereof, to obtain dyed or printed products of a color fast to light, wetness and chlorine with superior build-up and level dyeing properties.
游离酸形式的下式(I)所代表的不对称二恶嗪化合物:
其中 A₁ 和 A₂ 各自独立地为磺、卤、烷基或烷氧基,W 为未取代或取代的脂族或芳族桥基,X₁ 和 X₂ 各自独立地为氢、卤、烷基、烷氧基或苯氧基、R₁和 R₂ 各自独立地为氢或未取代或取代的烷基,R₃和 R₄ 各自独立地为氢、卤代、烷基、烷氧基或未取代或取代的氨基,Z 为纤维反应基团,m 和 n 各自独立地为 0 或 1,但 m≠n 和 ℓ 为 1 或 2。该化合物适用于纤维素纤维、天然和合成聚酰胺纤维、聚氨酯纤维、皮革等及其混纺纱线的染色和印花,以获得耐光、耐湿和耐氯的染色或印花产品,并具有优异的增染和匀染性能。
