Abstract
Water-soluble azo compounds of the formula (1) ##STR1## in which R is hydrogen or alkyl of 1 to 4 carbon atoms, X is alkyl of 1 to 6 carbon atoms substituted by carboxy or sulfo, or is phenyl substituted by 1 or 2 sulfo or carboxy or both, and Z is vinyl, .beta.-thiosulfatoethyl or .beta.-sulfatoethyl and M is hydrogen or the equivalent of a metal, and in which the second sulfo group in the naphthalene is bonded in the m-position or p-position relative to the acylated amino group. The new azo compounds are very valuable dyestuffs having fiber-reactive properties, and give color-fast and deep dyeings and prints on fiber materials made of cellulose or synthetic or natural polyamide fibers.
