Zusammenfassung:	Dyes of general formula in which X is halogen or an alkoxy group, Z is a sulphonamide or substituted sulphonamide group and Y1 and Y2 are hydrogen atoms or alkyl groups are prepared by diazotizing an amine of formula and coupling to a compound of formula in which the symbols are as above. The sulphonamide group contains a reactive hydrogen atom and several sulphonamide groups are specified. The dyes are yellow in colour and are used on polyamides, acrylonitrile and cellulosic material.
