New reactive azo dyes. Dyes of formula (I): D=aromatic, carbocyclic, or heterocyclic; X = H, or SO3H; R = R1 = H or lower alkyl; Z = reactive acryloyl opt. substituted reactive propionyl or halo-substituted reactive cyclobutanecarbonyl) are suitable for dyeing OH- and N-containing textiles, e.g. cellulosic, but especially wool, silk and synthetic fibres, e.g. super polyamide, polyurethane. Fastness to wetness and light, and brightness, are particularly good. |
