    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.
