    Abstract: Azo dyes having a 2,6-diamino-pyridine as coupling component, one of the amino groups bearing a bicyclic or polycyclic non-aromatic radical as a substituent. The dyes are eminently suitable as disperse dyes, particularly for synthetic linear polyesters, and give bright dyeings having excellent fastness properties.

    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: Title dyes are of formula: D-N=N-A (I) where D is the residue of a diazotisable aniline substd by in not 1 2nd order substit., or of a diazotisable amino-naphthalene, aminobiphenyl, aminoazobenzene, aminoanthraquinone, or heterocyclic amine, and A is a gp. of formula: where Z is H or a (substd). (cyclo)aliphatic, araliphatic aromatic, or heterocyclic gp; Z1 is H or a (substd). (cyclo)aliphatic, araliphatic or aromatic gp; Z2 is H or a (substd) aliphatic gp. or Z1 and Z2 form a heterocyclic gp. with the N atom; Z3 has the same meaning as Z1, Z4 has the same meaning as Z2, Z3 and Z4 may form a heterocyclic gp. with the N atom, and 1 of the gps. Z1-Z4 is not H. Suitable 2nd order substits. include NO2. CN, alkanoyl, aroyl, alkyl- or phenyl-sulphonyl, carbalkoxy (substd). carbamoyl, or sulphamoyl, or sulphonic acid ester gps. I are yellow to blue and can be used to dye polyacrylonitrile, synthetic polyamide, cellulose, ester and esp. linear polyester textiles. Fast dyeings of good colour strength are obtd.

    Abstract: The dyes are of formula D-N=N-A, (in which D is the group of a diazo component and A is a group of formula (I) or (II): in which B is hydrogen, alkyl opt. substd. with hydroxy, alkoxy, alkanoyl oxy, or phenoxy, aralkyl cycloalkyl or opt. substd. phenyl, R is hydrogen, 1-8 C alkyl, 2-7 C hydroxyalkyl, 3-11 C alkoxyalkyl, up to 11 C phenoxyalkyl, 2-15 C carbalkoxyalkyl, up to 15 C acyloxyalkyl, opt. substd. phenyl, cyclohexyl, benzyl, phenylethyl or epsilon -N-pyrrolidonalkyl, R1 is hydrogen, 1-8 C alkyl, 2-7 C hydroxyalkyl or up to 15 C acyloxyalkyl, or RR1 together with N form a pyrrolidine, piperidine or morpholine group, R2 is as R and R3 as R1, but not all are hydrogen. The alkyl chains may be interrupted by O atoms. The dyes are yellow to blue and suitable for colouring of textiles of polyacrylonitrile, synthetic polyamides, cellulose esters, and esp. linear polyester, giving strong colours with good fastness.
