Azo dyestuffs possessing antimicrobial properties

Abstract

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.
