Abstract
1322705 Disazo dyes IMPERIAL CHEMICAL INDUSTRIES Ltd 6 July 1970 [17 July 1969] 36096/69 Heading C4P The invention comprises disazo dyes of formula wherein E is the residue of an amino-groupcontaining coupling component of the benzene or naphthalene series, the -SO 3 H group in ring A. is in m- or p-position to -N = N- and ring B may contain OH and/or SO 3 H substituents, the dyes containing not more than three SO 3 H groups. The dyes are prepared by successive coupling reactions starting with the diazotized aminophenol-sulphonic acid. The dyes are used to colour synthetic polyamide fibres in blue and violet shades.
