    摘要: Fiber-reactive disazo dyes correspond to formula I, ##STR1## and they are present as free acids or in salt form. They are used as reactive dyes for dyeing or printing hydroxy-group-containing or nitrogen-containing organic substrates, especially leather or fibrous material, which consists of or contains natural or synthetic polyamides or natural or regenerated cellulose. The dyeings obtained have high fixation values and good light fastness.
