| titleOfInvention | Dye mixtures containing azo dyes with a coupling component from the diaminopyridine series |
| abstract | The mixts. contain at least six (6-12) similarly coloured 2,6-diamino-3-azo-5-cyano-6-methylpyridine deriv. dyes of formula (I), D = residue of a diazo component of the aniline, aminothiophene, amino(iso)thiazole or aminobenzisothiazole series; one of X1, X2 = NH2, and the other = -NR1-L-O-R2; L = 2-8C alkylene (opt. interrupted by 1 or 2 ether O functions); R1 = H or 1-4C alkyl (opt. substd. by OH, 1-4C alkoxy or 1-8C alkanoyloxy); R2 = H, 1-4C alkyl, benzyl, phenyl or 1-8C alkanoyl. More specifically, D = gp. of formula (IIa)-(IIe), esp. (IIb)-(IId), where Z1 = H, NO2, CN, 1-9C alkoxycarbonyl or 1-9C alkylamino carbonyl (both opt. interrupted by 1 or 2 ether O functions), CF3, 1-4C alkylsulphonyl, 3-(1-4C alkyl)-1,2,4-oxadiazol-5-yl or 3-phenyl-1,2,4-oxadiazol-5-yl; Z2 = H, Cl, Br, CN, Me, OMe, OEt, phenylazo or benzoyl (opt. substd. by Me, OMe or Cl); Z3 = H, CN, Cl, Br or 1-9C alkoxycarbonyl (opt. interrupted by 1 or 2 ether O); or Z2+Z3 = -CO-NA'-CO-; A' = H or 1-4C alkyl; Z4 = CN, CHO, NO2, 1-9C alkoxycarbonyl (opt. interrupted by 1 or 2 ether O), phenylazo (opt. substd. by CN) or A2-C(CN)=CH-; A2 = CN, CHO, 1-9C alkoxycarbonyl (opt. interrupted by 1 or 2 ether O); Z5 = H, 1-4C alkyl, 1-4C alkoxy, phenyl or benzyl (both opt. substd. by Me, OMe or Cl), 1-4C alkylsulphonyl, Cl, Br or 1-9C alkoxycarbonyl (opt. interrupted by 1 or 2 ether O; Z6 = 1-4C alkyl, phenyl or benzyl (both opt. substd. by Me, OMe or Cl), CN, NO2, 1-9C alkoxycarbonyl (opt. interrupted by 1 or 2 ether O) or 1-4C alkylsulphonyl; Z7 = 1-4C alkyl, phenyl or benzyl (both opt. substd. by Me, OMe or Cl) or 1-4C alkylsulphonyl; Z8 = NO2, CN or 1-4C alkylsulphonyl; R2 = 1-5C alkanoyl (esp. acetyl); L = 4-8C alkylene interrupted by 1 or 2 ether O. The mixts. are prepd. e.g. by: (1) reacting 2,6-dichloro-3-cyano-4-methyl pyridine with NH3 to give a mixt. of 2-chloro-3-cyano-4-methyl-6-aminopyridine and the corresp. 2-amino-6-chloro cpd. in molar ratio 3:17 to 2:3; (2) reacting the mixt. with amines of formula R1-NH-L-OR3 (R3 = H, 1-4C alkyl, benzyl or phenyl, R3 is H in the amine(s) to give a mixt. of 2-(NR-L-OH)-3-cyano-4-methyl-6-aminopyridines and the corresp. 2-amino-6-(NR'-L-OH) cpds.; (3) O-acylating with a 1-8C alkanoic acid (opt. in presence of mineral acid); and (4) coupling with a diazonium salt derived from DNH2. USE/ADVANTAGE - Use of the mixt. for dyeing or printing textiles is claimed. Typically they are used with fibres or fabrics of cellulose ester, polyamide, polyester-cellulose or -wool blends or esp. polyester, e.g. giving blue, violet, red, orange, brown or yellow shades. Unlike the individual dyes (I) or known mixts. of up to 4 cpds. (I) (see US4855412/3, EP-201896), the exhaustion behaviour of the present mixts. is virtually independent of temp. the mixts. also have high exhaustion and very low tendency to recrystallise in dispersed form. |
