Abstract

1332899 Disperse monoazo dyes YORKSHIRE CHEMICALS Ltd 9 Oct 1970 [18 Oct 1969] 51251/69 Heading C4P The invention comprises water-insoluble monoazo dyes of formula wherein R<SP>1</SP> is the residue of an aryl or heterocyclic diazo component and the dyes may be further substituted other than by COOH or SO 3 H groups. The dyes are prepared by azo coupling and may be used to colour hydrophobic fibres in particular polyesters in yellow to red and blue shades. Specification 478,514 is referred to.
