ABSTRACT:
The invention relates to novel azo dyes of the formula ##STR1## wherein R.sub.1 represents hydrogen, alkyl of 1 to 8 carbon atoms or the phenyl radical, R.sub.2 represents hydrogen, an acyl radical or a fibre-reactive radical, and D represents the radical of any diazo component, which dyes are useful for dyeing and printing a wide variety of natural and synthetic textile materials and leather; thus the acid dyes, which optionally contain fiber-reactive groups, are used for dyeing and printing materials such as cellulose and natural or synthetic polyamide. The cationic dyes are especially used in dyeing and printing polyacrylonitrile, and the disperse dyes are especially used in dyeing and printing polyester materials.
