Abstract

1489752 Disazo dyes IMPERIAL CHEMICAL INDUSTRIES Ltd 23 Sept 1975 [14 Oct 1974] 44403/74 Heading C4P Novel water-soluble disazo dyes having the formula (where R<SP>1</SP> and R<SP>2</SP> independently are H, hal, alkyl, alkoxy, acylamino or SO 3 H; the OH group in ring A is o- or mto the azo group and E is the residue of a coupling component of the amino benzene, aminonaphthalene, phenol, naphthol, pyrazolone, hydroxypyridone, aminopyrazole, indole or acetoacetarylamide series) are prepared by diazotizing an aminophenolsulphonic acid and couling with the appropriate aniline followed by diazotization of the aminoazo compound obtained and coupling with the appropriate coupling component. The preferred dyes contain one or two sulphonic acid groups. The dyes are used for colouring synthetic polyamide textile materials.
