Abstract
Compounds of the formula ##STR1## in which D is ##STR2## where R.sub.1 is hydrogen, (C.sub.1-4)alkyl or (C.sub.1-4)alkoxy, m and n are 1 or 2, and p is 0 or 1, with the proviso that n+p is 2 or 3, R.sub.2 is hydrogen or (C.sub.1-4)alkyl, R.sub.3 is (C.sub.1-4)alkyl, and Hal is fluorine, chlorine or bromine, and mixtures thereof, which compounds are in free acid or salt form, their production and use as reactive dyestuffs for hydroxy group-containing and amide group-containing organic substrates such as leather and textiles consisting of or comprising natural or synthetic polyamides (e.g., wool, silk and nylon) or natural or regenerated cellulose (e.g., cotton, viscose and spun rayon).
