Abstract

1358093 Monoazo dyes CIBA-GEIGY AG 4 Aug 1971 [7 Aug 1970] 36640/71 Heading C4P New monoazo dyes, free of SO 3 H groups but containing at least one COOH group, of formula wherein B is the radical of a coupling component, Y is -S- or -N=, R is H or a hydrocarbon radical, n is 1 or 2, n being 1 if Y is -S- or 2 if Y is -N= and ring D may be further substituted, are described. The dyes are prepared by azo coupling and are preferably used to colour a wide range of synthetic and semisynthetic fibres in orange, yellow and blue shades. Reference has been directed by the Comptroller to Specification 1,202,984.
