    Abstract: 1377505 Azo dyes from 2,6-diaminopyridine coupling components BADISCHE ANILIN- & SODA-FABRIK AG 17 Dec 1971 [19 Dec 1970 15 Nov 1971] 58653/71 Heading C4P Novel dyestuffs of the formula in which D is the radical of a diazo component the linking bond of which is attached to a condensed or uncondensed benzene, thiophene, isothiazole, thiazole, thiadiazole, triazole or pyrazole ring; X is -CN or -CONH 2 ; NR 2 R 3 may independently have any of the values of NRR 1 ; and either NRR 1 is pyrrolidino, piperidino, morpholino, the S-dioxide of thiomorpholino, piperazino or N 1 -methylpiperazino or R 1 is H or C 1-8 alkyl optionally substituted by OH, NH 2 or C 1-8 alkoxy or mono- or di-alkylamino and R is R 1 , C 1-8 alkyl which may also optionally be substituted by phenyl, phenoxy, optionally esterified carboxy or C 1-10 acyloxy, any of the open chains in the foregoing R groups optionally being interrupted by oxygen, or R is ethyl or propyl substituted in the omega position by an N-atom which is part of a 2-pyrrolidone or morpholine-S-oxide ring, or R is allyl, cyclohexyl optionally substituted by hydroxy or acyloxy, or phenyl optionally substituted by Cl, CN, CH 3 , OCH 3 , CH 3 NHCO, CH 3 OC 2 H 4 NHCO, C 2 H 5 , OC 2 H 5 , 2-hydroxyethyl, 2-hydroxyethoxy or 2-acyloxyethoxy are prepared by coupling of diazotized amines DNH 2 with appropriately substituted 3-cyano or carbamoyl-4-methylpyridines. Products wherein X is CN may be hydrolysed to the corresponding amides, and products containing free OH or CO 2 H groups may be acylated or esterified. The new dyes are yellow to green-blue and are suitable for dyeing acrylonitrile polymer textile material and, particularly, textile material of synthetic polyamides, cellulose esters and synthetic linear polyesters. The coupling components and their' 6-chloroprecursors are described and claimed in Specification 1,377,506.

    Abstract: New dyes have the formula (I): where D is the residue of a diazo component of the benzene, naphthalene, diphenyl, azobenzene, thiophene, benz(iso)thiazole, thiazole, (benz)triazole, indazole, pyrazole or anthraquinone series, X is CN or CONH2, R is H, 1-8C alkyl, alkyl substd. by OH, 1-8C alkoxy, COOH, 2-6C carbalkoxy, 1-10C acyloxy or is not >8C alkylamino or interrupted by O, phenyl (opt. substd. by Cl, CH3, C2H5, OHCH2CH2, CH3O or C2H5O), cyclohexyl, benzyl, phenylethyl or omega-N-pyrrolidonyl-alkyl with 2-3C in the alkyl gp., R1 is H, 1-8C alkyl, alkyl substd. by OH, 1-8C alkoxy, or is not 8C alkylamino, R and R1 together with the N atom represent the residue of pyrrolidine, piperidine, morpholine or (N-methyl)-piperazine, R2 is as in R, R3 is as in R1, and R2 + R3 are as in R + R1. The dyes are yellow to greenish-blue, and are suitable for dyeing or printing polyacrylonitrile, polyamides, cellulose esters and polyesters. Strong dyeings with good resistance, esp. to thermo-fixing and light are obtd.

    Abstract: Dye mixtures containing at least 6 identically coloured dyes of the formula in which D is the radical of a diazo component from the aniline, aminothiophene, aminothiazole, aminoisothiazole or aminobenzisothiazole series, and one of the radicals X and X is amino and the other is a radical of the formula in which L is optionally substituted C2-C8-alkylene, R is hydrogen or optionally substituted C1-C4-alkyl, and R is hydrogen, C1-C4-alkyl, benzyl, phenyl or C1-C8-alkanoyl, their use for the dyeing or printing of textile materials, dye mixtures containing thienylazopyridine dyes and anthraquinone dyes, and their use for the dyeing or printing of textile materials.

    Abstract: Polyazo dyes of the formula I where one of the two radicals X1 and X2 is hydroxyl and the other is amino, p and q are each independently of the other 0 or 1, D1 and D2 are each independently of the other a radical of the formula and B is a bridge member are prepared using novel sulfonamide intermediates and are useful as dyes for dyeing natural or synthetic substrates.
