Abstract

1489753 Disazo dyes IMPERIAL CHEMICAL INDUSTRIES Ltd 23 Sept 1975 [14 Oct 1974] 44405/74 Heading C4P Novel water-soluble disazo dyes having the formula (where B may optionally be substituted by sulphonic and/or hydroxy groups and E is the residue of a coupling component of the phenol, pyrazolone, hydroxypyridone, aminopyrazole, indole or acetoacetarylamide series) are prepared by diazotizing an aminophenolsulphonic acid, coupling with an aminonaphthalene, then diazotizing the aminomonoazo compound formed and coupling with the appropriate coupling component. The preferred dyes contain two sulphonic acid groups. The dyes are used for colouring synthetic polyamide textile materials.
