Abstract

The novel dyes correspond to the formula <IMAGE> in which A, B, R, W1, W2, X and n have the meaning given in Patent Claim 1. The dyes of formula 1 are prepared, for example, by diazotising a compound of formula <IMAGE> coupling the diazotisation product with a compound of formula 5 <IMAGE> where X is chlorine, and reacting the resulting compound of formula I, wherein X is chlorine, with one mole of a compound of the formula HX', where X' is alpha ) optionally substituted amino or morpholino or beta ) alkoxy or aryloxy. The novel dyes are suitable for dyeing or printing cellulose-containing fibres.
