Реферат: Disperse dyestuffs, 4-(heterocyclyl-azo)-aniline cpds. (I) of formula (I) are new. In (I) R1 = e.g. phenoxycarbonyl-1-6 C alkyl, in which the phenyl ring has 0-2 halogen, alkyl or alkoxy substits. or 0-1 CF3 OH, NO2, CHO, CN, 1-4 C alkylcarbonyl, 1-2 C alkylcarbonyloxy, aminocarbonyl, 1-3 C alkoxycarbonyl, 1-C alkoxy-2-3 C alkoxycarbonyl, 1-4 C acylamino or phenyl substits.; R2 = e.g. (cyano)alkyl, (halo)alkenyl, alkynyl, benzyl, or alkoxycarbonyloxyalkyl; or, if D = 2,4-dinitrophenyl, opt. with another substit. in the 5- or 6-position or a heterocyclic gp., R2 may also = H; or R2 + R4 + the intervening atoms = a 6-membered heterocycle with 0-3 Me gps.; R3 = e.g. H, halogen, OH or 1-4 C alkyl; or, if D = 2-cyano-4-nitrophenyl, phenyl with 3 substits. or a heterocycli gp., R3 may also = e.g. formylamino, 1-3 C alkylcarbonylamino, 2-3 C alkenylcarbonylamino, 1-2 C alkoxy-1-3 alkylcarbonylamino, 1-4 C alkoxycarbonylamino or 1-3 C alkylsulphonylamino; R4 = H, halogen, -3 C alkoxy or 1-3 C alkoxy-2-3 C alkoxy; D = a diazo component of the triazolyl, pyrazolyl, cyano-1-2 C alkylimidazolyl, 4-chlorothiazol-2-yl, isothiazol-5-yl, or 4-chloro-thien-2-yl series, a 3-phenyl-1,2,4-thiadiazol-5-yl or 5-nitrothiazol-2-yl gp., a phenyl gp. with up to 3 substits. but free from sulphonyl gps or a substd. thien-2-yl, 3-cyano-5-phenylazo-thien -2-yl or 4-alkoxycarbonyl-5-cyano-thiazol-2-yl gp. of the formulae (II)-(IV) a = CN, alkoxycarbonyl, aminocarbonyl, mono- or dialkylaminocarbonyl or alkylcarbonyl; b = H, alkyl, phenyl or alkylcarbonyl; c = CN, CHO, alkoxycarbonyl, mono- or dialkylaminocarbonyl aminosulphonyl, d = H, Me, halogen or NO2; e = H, halogen, MeO, CN or NO2; f = H, Me or Ph; the alkyl, alkenyl and alkynyl gps. contain up to 6 C and the alkyl gps. may have 1 or 2 of the usual substits. for disperse dyestuffs. USE/ADVANTAGE - (I) and their mixts. are for dyeing, slop pad dyeing or printing (semi)synthetic high mol. hydrophobic fibres or filaments or materials m
Process for the pad-dyeing or printing of textile material of natural or synthetic polyamide fibers or mixtures thereof with other fibers with reactive dyestuffs
