Fiber reactive azo dyes containing a morpholinyl-, piperazinyl- or piperidnyl- substituted flurotriazinyl radical

Abstract

An azo dyestuff of the formula ##STR1## in which u and v=H or SO.sub.3 H and u.noteq.v, R=H, unsubstituted C.sub.1 -C.sub.4 -alkyl or C.sub.1 -C.sub.4 -alkyl substituted by OH, halogen, SO.sub.3 H or OSO.sub.3 H, m=0 or 1 and ##STR2## in which R.sub.1 =H, unsubstituted C.sub.1 -C.sub.6 -alkyl or C.sub.1 -C.sub.6 -alkyl substituted by OH, OSO.sub.3 H, SO.sub.3 H or COOH. Such dye is particularly suitable for producing on cotton red dyeings and prints having excellent fiber-dyestuff bond stability, stability to oxidizing agents and wash-off properties.
