    Abstract: Method for the preparation of fibre-reactive formazan dyes by diazotisation of a formyl-protected hydroxyphenylenediamine and coupling with a hydrazone compound, metallisation, elimination of the protective group, and reaction with a halotriazine and optionally subsequently with an amine or a hydroxy compound; and aminophenols as intermediates for the novel process.

    Abstract: New reactive dyestuffs (I) with a branched alk(en)ylsulphonylaryl substit. are of the formula (I) where Z1 = H, halogen, 1-4C alkyl, NO2, HOSO2, COOH, -NW1W2 or S(O)aW3; W1-2 independently = H, 1-4C alkyl or 2-4C alkyl substd. by OH, 1-4C alkanoyloxy, 1-4C alkoxy, HOSO2, Cl or Br; a = 0 or 2; W3 = 1-4C alkyl or 2-4C alkyl substd. by OH, Cl, Br, 1-4C alkoxy, HOSO2, 1-4C alkanoyloxy or OSO3H; Z2 = OH, 1-4C alkoxy, SH or Z1`; Z3 = -C(CH2-W4)=CH-CH3, -CH(CH2-W4)-CH=CH2 or -CH(CH2-W4)-CHW4-CH3 or, if Y2 is in the o-position to the SO2-Z3 gp., Z2 + Z3 = -CH(CH2-W4)-CH(CH3)-W5-; W4 = OH, 1-4C alkoxy, Cl, 1-4C alkanoyloxy, 1-4C alkylsulphonyloxy, phenylsulphonyloxy, o- or p-tolylsulphonyloxy or (thio)sulphato; W5 =O, S, NH or 1-4C alkylimino, opt. substd. by OH, 2-hydroxyethylthio or 2-hydroxyethylsulphonyl; X = (1) the radical of a chromophore, opt. contg. other reaction gps. and derived from an opt. metallised mon- or disazo dyestuff, triphenodioxazine, anthraquinone, metallised formazan or metallised phthalocyanine; or (2) the radical of a coupling component, opt. contg. the radical of a diazo component attached by an azo gp. and opt. with other reactive gps.; L = (1) a bridging gp. of formula -N(Q1)-A- (IIA) or (IIB), or (2) an azo bridge; Q1 = H or 1-4C alkyl; Q2-3 independently = H or 1-4C alkyl; Q4 = a projecting gp.; A = a chemical bond or 1-4C alkylene; and ring B is opt. benzo-anellated. USE/ADVANTAGE - For dyeing or printing substrates contg. OH gps. or N atoms. Esp. for dyeing leather and fibrous materials based on natural or synthetic polyamides or natural or regenerated cellulose, partic. wool and cotton textiles. (I) are esp. suitable for the exhaustion and cold dwell processes. They give high yield and have high fastness to wet, esp. boiling soda, and brilliant hue, whilst the unfixed (I) can be washed out very easily.
