摘要

New sulphonated mono- or diazo dyestuffs (I) with a 4,6-di-(vinyl or beta-substd.-ethylsulphonyalkylamino)-s-triazin-Z-yl-amino and 1 or 2 vinyl- or beta-substd.-ethyl-sulphonyl gps. are of formula as (Y-SO2)n-F-Z (1); Z = a gp. of formula (2): F = the radical of a mono- or disazo dyestuff contg. SO3H gp.(s). and opt. a heavy metal; A and B independently = gps. of formulae -N(W)-G(R)-(CH2)k-SO2-Y1 (3a) or (3b) G = a linear or branched 1-6, pref. 2-4C alkylene gp., a linear or branched 2-6, pref. 2 or 3C alkylene gp. with 1 or 2 hetero gps. in the chain or a 5-8C (methyl)cycloalkylene gp.; R = H, C1, Br, F, OH, SO3H, CN, COOH, carbamoyl, 2-5C carbalkoxy, 2-5C alkanoyloxy, benzoylamino (opt. with 1 or 2 SO3H, COOH, Me, Et, MeO, EtO or C1 substits.) or -SO2-Y2; k = 0, 1 or 2; k = 0, 1 or 2; k(asterisk) = 0, 1, 2 or 3; -N-X = a divalent heterocyclic gp. with one or two 1-5C alkylene gps. and opt. 1 or 2 hetero-atoms; n = 1 or 2, pref. 1; Y and Y1 independently = vinyl,beta-(thio)sulphatoethyl, beta-haloethyl, beta-phosphatoethyl or beta-acetoxyethyl; Y2 = as Y or beta-hydroxyethyl; Ra = H or linear or branched 1-4C alkyl, opt. with a COOH, SO3H, CN, OH or C1 substit.; W = H, Me, sulphomethyl, carboxymethyl, linear or branched 2-6C alkyl (opt. with 1 or 2 MeO, 1 or 2 MeO, EtO, COOH, SO3H, OH or halogen substits.), 5-8CC (methl)cycloalkylene or phenyl (opt. with 1-4C alkyl, 1-4C alkoxy, COOH, SO3H or halogen substits.). USE/ADVANTAGE - (I) are claimed for dyeing (including printing) material, esp. fibrous material, contg. OH and/or carbon-amido gps., pref. in conjunction with thermal and/or alkaline fixing. useful for dyeing cellulose fibres (cotton) and synthetic or natural polyamides (wool).
