摘要: The invention is concerned with compounds according to the formula
and their salts wherein
R 1 represents hydrogen or-SO 3 H,
R 2 represents hydrogen, methyl, -NHCONH 2 or -NHCOCH 3 and,
R 3 represents hydrogen, C 1-4 alkyl, preferably methyl or ethyl, or C 1-4 alkyl substituted with CN, OH, Cl, F or -SO 3 H.
These compounds are useful as fibre-reactive dyestuffs in dyeing and printing hydroxy-group-containing and nitrogen-containing organic substrates.摘要翻译: 本发明涉及根据式CHEM的化合物及其盐,其中R 1表示氢或-SO 3 H,R 2表示氢,甲基,-NHCONH 2或-NHCOCH 3,且R 3表示氢,C 1-4烷基,优选甲基或乙基, 或被CN,OH,Cl,F或-SO 3 H取代的C 1-4烷基。 这些化合物可用作染色和印刷含羟基和含氮有机基材中的纤维活性染料。
