REACTIVE AZO COMPOUNDS, PROCESSES FOR THEIR PREPARATION AND THEIR USE FOR DYEING FIBERS AND TEXTILES

摘要

Reactive azo compounds, in the free form, represented by the formula: wherein R1 is amino or methyl, R2 is anilino having one or two sulfo or carboxy and optionally substituted by methyl or chloro; methoxy; amino, alkylamino having 1 to 4 carbon atoms and optionally substituted by hydroxy, carboxy or sulfo, and R3 and R3 min each represents chloro or fluoro independently, which give clear and fast dyeings when used for dyeing, especially printing or continuous dyeing of cellulosic fibers, processes for preparing said compounds and their use for dyeing fibers.
