    Abstract: Dyestuff mixtures comprising at least one azo dyestuff whose diazo component is 2-amino-3,5-dicyano-4-methylthiophene and whose coupling component originates from the 2-amino-4-thienylthiazole series, and at least one azo dyestuff whose diazo component is 2-amino-3,5-dicyano-4-methylthiophene, 2-amino-3-alkoxycarbonyl-5-cyano-4-methylthiophene or 2-amino-5-alkoxycarbonyl-3-cyano-4-methylthiophene and whose coupling component originates from the 3-cyano-4-methyl-2,6-diaminopyridine series, and/or at least one azo dyestuff whose diazo component is a 2,6-dicyano-4-alkylaniline and whose coupling component originates from the m-phenylenediamine series, and the use of the novel dyestuff mixtures for the dyeing or printing of synthetic fabrics.

    Abstract: Disclosed are dye mixtures containing 35 to 90 % by wt., relative to the weight of the dyes, of a dye of formula (I), in which n is 1 and R is C1-C4 alkyl, plus 10 to 65 % by wt., relative to the weight of the dyes, of a dye of formula (I) in which n is 2 and R is C1-C4 alkyl. Also disclosed are dye preparations containing such dye mixtures and the use of the dye mixtures to dye or print on textile fibres or woven fabrics.

    Abstract: Diaminopyridine cpds. are of formula (I), in which one of X1 and X2 = H, 1-4C alkyl, halogen or nitro and the other = CN; R1 = H, 1-4C alkyl or phenyl; R2 and R3 (same or different) = H, 1-4C alkyl or 1-4C alkoxy; R4 = H or 1-4C alkyl and R5 = 1-10C alyl (which may be interrupted by 1-3 ethercal O atoms and is opt. substd. by OH, 1-4C alkanoyloxy, phenoxy, phenyl, tetrahydrofuranyl or tetrahydropyranyl), 3-4C alkenyl or 5-7C cycloalkyl, are prepd. by reacting dichloropyridines of formula (II) in a first step with an amine of formula (III) R5-NH2 (III) at a temp. of 10-80 deg.C in the presence of a base and an inert organic diluent and/or water, and subsequently removing the diluent, then, opt. after intermediate isolation of the reaction prod., reacting this in a second step with an aniline cpd. of formula (IV) in the melt at 90-165 deg.C in weakly acid medium. USE/ADVANTAGE - The process is simple to carry out and gives high yields of the (I) of high purity, esp. high isomer purity. (I) are useful intermediates, esp. as coupling components in the synthesis of dyestuffs.
