Abstract

1,160,638. Reactive azo dyes. FARBENFABKIKEN BAYER A.G. 19 Dec., 1967 [23 Dec., 1966], No. 57568/67. Heading C4P. The invention comprises dyestuffs of general formula wherein X is a triazine ring which contains at least one Cl or Br substituent which will react with fibre -OH or amino groups to form a covalent bond, R is H, C 1 -C 4 alkyl or is halogen, R 1 is an optionally substituted aryl radical and Z is CH 3 , COOH or a carboalkoxy group. They are prepared by diazotization and coupling or by reacting the corresponding amino azo dye with a reactant e.g. the di-chlorotriazines to introduce the radical X. The dyestuffs dye natural or regenerated cellulose, wool, silk and synthetic superpolyamides in yellow shades.
