Azo dyestuffs containing triazines and vattable polycyclic quinones

The invention comprises dyes wherein a 1,3,5- triazine ring is bound to two vattable polycyclic quinones, free from SO 3 H groups, by -NH- groups and through an -O- or -NH- group to an azo dye that is free, in the o-positions to the azo bridge, from salt-forming metallizable groups. The dyes are prepared by the usual condensation processes from halotriazines. The polycyclic quinones are preferably aminoanthraquinones. The dyes are preferably used to colour cellulose materials by vat-dyeing processes in blue, green, yellow, red and brown shades. The dyes may also be used to colour synthetic polyamide and polyester fibres and to colour synthetic polymers (see Division C3).
