Abstract

Fibre-reactive, water-soluble azo dyestuffs, which have an acetoacetylarylide radical as the coupling component, are prepared by diazotisation and coupling of the corresponding diazo and coupling components. They are especially suitable for dyeing cellulose fibres by the methods customary for reactive dyestuffs and yield full, clear, yellow to very brilliant greenish-yellow dyeings and prints thereon having very good fastnesses, such as fastnesses to chlorinated bathwater, chlorine bleach, milling, rubbing and alkali. They are furthermore distinguished by a very good tinctorial strength and by a very good dye composition. In addition, they also advantageously dye fibre materials of animal origin and synthetic polyamide and polyurethane fibres and also leather.
