摘要:
Disazo dyestuffs, which in the form of the free acid, have the formula ##STR1## wherein R.sub.1 is an aromatic radical, an aliphatic radical with 1-4 C atoms or a dialkylamino radical;R.sub.2 is chlorine, bromine, alkoxy or alkyl;R.sub.3 and R.sub.4 are hydrogen, chlorine, bromine, alkoxy group or alkyl;R.sub.5 and R.sub.6 are hydrogen, C.sub.1 -C.sub.4 -alkyl or C.sub.1 -C.sub.4 -alkoxy;R.sub.7 is C.sub.1 -C.sub.4 -alkyl;B is a 1,4-phenylene, 1,4-naphthylene or tetrahydro-1,4-naphthylene radical; andm is 0, 1 or 2;Are disclosed. The resulting dyestuffs are used for the dyeing fibers containing of amide groups, for example those of wool, silk and polyamide, such as poly-.epsilon.-caprolactam or the reaction product of hexamethylene-diamine with adipic acid. The resulting dyeings, especially those on polyamide materials, are distinguished by good fastness properties, especially by good wet fastness properties and good light fastness properties.

摘要:
Azo dyestuffs, possessing antimicrobial properties, having the formula: ##STR1## wherein X is --OCH.sub.3 or --SO.sub.3 Na, Y is ##STR2## or --SO.sub.2 CH.sub.2 CH.sub.2 OSO.sub.3 Na, A is a derivative of naphthalene containing one or more of the following groups --OH, --NH.sub.2, ##STR3## --SO.sub.3 Na. The use of the azo dyestuffs according to the present invention makes it possible to considerably simplify the process of finishing of fibrous materials. Antimicrobial properties are imparted simultaneously with the dye to both protein and cellulose fibrous materials.
