Reactive azine dyestuffs of the formula: ##SPC1## Wherein Am is selected from a group consisting of anilino, di(lower alkyl)amino and N(lower alkyl)benzylamino radicals, one of Y.sup.1 and Y.sup.2 is H or SO.sub.3 H and the other is H or an alkyl or alkoxy group of 1-4 carbon atoms, One of X.sup.1 or X.sup.2 is H, SO.sub.3 H, --SO.sub.2 CH.sub.2 CH.sub.2 OSO.sub.3 H or --SO.sub.2 CH=CH.sub.2 and the other is H, an alkyl or alkoxy group of 1-4 carbon atoms, Cl or CO.sub.2 H, X.sup.3 is H, an alkyl group of 1-4 carbon atoms or SO.sub.3 H, when the dotted fused ring is present B is absent and when the dotted fused ring is absent B is H or an alkyl or alkoxy group of 1-4 carbon atoms, At least one of the pendant benzene nuclei contains a NHQ group where Q is a cellulose-reactive group except when X.sup.1 or X.sup.2 is --SO.sub.2 CH.sub.2 CH.sub.2 OSO.sub.3 H or --SO.sub.2 CH=CH.sub.2 and the dyestuff as a whole contains at least 2 sulphonic acid groups. The products are reactive dyes for cellulose which are colored in strong bright blue or reddish-blue shades of excellent fastness to washing and of a reasonable fastness to light, especially in respect of wet fading.
化学式为:##SPC1## 其中Am选自由苯胺基、二(低碳基)氨基和N(低碳基)苯甲基氨基等基团组成的群体中,Y1和Y2中的一个是H或SO3H,另一个是1-4个碳原子的烷基或烷氧基,X1或X2中的一个是H、SO3H、--SO2CH2CH2OSO3H或--SO2CH=CH2,另一个是1-4个碳原子的烷基或烷氧基、Cl或CO2H,X3是H、1-4个碳原子的烷基或SO3H,当存在点状融合环时,B不存在,当不存在点状融合环时,B是H或1-4个碳原子的烷基或烷氧基。至少一个悬挂苯核含有NHQ基团,其中Q是除非X1或X2是--SO2CH2CH2OSO3H或--SO2CH=CH2时的纤维素反应基团。整个染料至少含有2个磺酸基团。这些产品是对纤维素的反应染料,颜色为强烈的亮蓝色或红蓝色,洗涤牢度优异,光牢度合理,特别是湿度褪色方面。
