Abstract
A compound of formula < IMAGE > is a) coupled with the diazonium salt of an amine of formula < IMAGE > or b) coupled with diazotised 5-nitroaniline-2-sulphonic acid or 5-nitroaniline-2,4-disulphonic acid, thereafter the nitro group is reduced to the amino group and the resulting disazo compound of formula < IMAGE > is condensed with a compound of formula < IMAGE > The novel dyes of formula < IMAGE > wherein X1, X2, X3, Y1, Y2, X, Z and hal have the meanings given in Claim 1, are primarily useful as reactive dyes for cellulosic textiles.
