Abstract
There are described monoazo compounds which exhibit fiber-reactive properties and dye hydroxy- and/or carboxamido-containing materials, in particular fiber materials, such as, for example, cellulose fiber materials and wool, in shades of high color strength and good fastness properties and can also be used in particular for resist and discharge printing. They have the formula (1) ##STR1## in which: A is substituted or unsubstituted phenylene or unsubstituted or sulfo-substituted naphthylene, the groups X--SO.sub.2 -- and --SO.sub.2 X.sup.1 are fiber-reactive groups from the vinylsulfonyl series, n is the number 1 or 2, M is hydrogen or an alkali metal, R is hydrogen or a lower alkyl, W is phenylene or lower alkylene, B is lower alkyl and one group --SO.sub.3 M is bound to the 8-naphthol radical in the 3- or 4-position.
