Abstract: Azo dyestuffs which contain at least one water-solubilizing group and have the formula ##STR1## wherein K stands for the radical of a coupling component,R.sub.1 stands for CN, COOX, CONXY or COZ,R.sub.2 stands for hydrogen, halogen, CN, alkyl or aryl,R.sub.3 stands for alkyl or aryl,X stands for H, alkyl, alkenyl, cycloalkyl, aryl or aralkyl andY stands for H or alkyl andZ stands for alkyl or aryl,are highly suitable for dyeing polyamide fibres. The resulting dyeings are distinguished by good all-round fastness properties.

Abstract: Monoazo compounds of the formula ##STR1## in which one of the two substituents R.sub.1 or R.sub.2 or both substituents are C.sub.3 -C.sub.8 -alkyl or a group of the formula ##STR2## in which R.sub.3 and R.sub.4 are independently of each other hydrogen or C.sub.1 -C.sub.4 -alkyl and R.sub.5 is hydrogen, halogen or C.sub.1 -C.sub.4 -alkyl and the other of the two substitutents R.sub.1 or R.sub.2, when the two are not C.sub.3 -C.sub.8 -alkyl or a group of the formula (1a), is hydrogen, halogen or C.sub.1 -C.sub.4 -alkyl, and KK is the radical of a coupling component which is free of water-solubilizing groups the two described. These compounds can be used as dyes for dyeing or printing for example polyester fibre materials.

Abstract: This invention relates to novel azo dyes containing a 4-nitropyrazole azo moiety which may be substituted, for example, with an alkyl group which itself may be substituted, and an aniline coupler which may be substituted. The dyes produce bright red shades on hydrophobic textile fiber including polyesters, polyamides, and cellulose esters and show unexpected improvements in one or more of such properties as fastness to light, wash, ozone, gas such as oxides of nitrogen, perspiration, crock and sublimation, dyeability at desirable low energy levels to deep shades, build, pH stability, bloom resistance, leveling, migration, dye bath exhaustion, dye transfer, and the like.

Abstract: Process for the production of triazoles of the formula ##STR1## in which R.sub.1 is hydrogen or an aliphatic or aromatic substituent conventional for diazo components of disperse dyes, which substituent is bound to the N-atom in the 1- or 2-position of the triazole nucleus through a carbon atom, andK is a coupling component radicalcomprising treating a compound of the formula ##STR2## with a dehydrating agent.
