Abstract

1483909 Disazo dyes IMPERIAL CHEMICAL INDUSTRIES Ltd 4 Sept 1975 [14 Oct 1974] 44401/74 Heading C4P Novel water-soluble disazo dyes have the formula where A is alkyl or aryl; R<SP>1</SP> is H or alkyl and the alkyl groups of A and R<SP>1</SP> may be substituted by hal, alkoxy, OH, or CN and A, when aryl and ring B may be substituted by hal, NO 2 , alkyl, alkoxy, OH, NO 2 , or acylamino; R<SP>2</SP> and R<SP>3</SP> independently are H, alkyl or alkoxy; m=0-2 and E is a residue of formulae (II) or (III) where the OH in (II) is o- or pto the azo group; R<SP>4</SP> is H, amino, alkylamino or arylamino; n=0-2 and m+2=1, 2 or 3; R<SP>5</SP> is H, alkyl, acyl or aryl optionally substituted by alkyl, alkoxy, hal, OH or acylamino; p=0-2 and m+p=1, 2 or 3. The dyes are prepared by diazotization and coupling. The dyes are used for colouring synthetic polyamide textile materials.
