Abstract

1,274,047. Disperse azo dyes. FARBENFABRIKEN BAYER A.G. 30 July, 1969 [14 Aug., 1968], No. 38308/69. Heading C4P. New disperse azo dyes, free from COOH and SO 3 H groups, of formula wherein R 1 and R 2 are H or CH 3 , A is an alkoxycarbonyl group which may be substituted or a carbamoyl group which may be substituted by an alkyl, aralkyl or aryl radical or by two alkyl groups which may form a heterocyclic ring, B is as A or CN and X, Y and Z are H or substituents are prepared by azo coupling or by treating dyes of the above formula containing COOH or SO 3 H groups as substituents X, Y or Z or a COOH group as substituent A or B with an alcohol, an amine or aqueous NH 3 to form the ester or amide group. The dyes are used to colour hydrophobic fibres, in particular polyester fibres in yellow shades.
