Abstract
Water-soluble azo dyes and their heavy metal complex derivatives, such as copper, cobalt and chromium complex azo dyes are described, which have the general formula (1) shown below, have fiber-reactive properties and dye natural and synthetic hydroxyl- and/or carboxamido-containing materials, in particular fiber materials, such as wool and in particular cellulose fiber materials, by the dyeing and printing processes customary for fiber-reactive dyes, in hues which have high color strength and good fastness properties. ##STR1##
