Abstract

1336673 Disazo dyes BADISCHE ANILIN- & SODA-FABRIK AG 19 April 1971 [2 April 1970] 25827/71 Heading C4P New disazo dyes, free from SO 3 H groups, of formula wherein X<SP>1</SP> is H, Cl, Br, C 1-4 alkyl, CH 3 O, C 2 H 5 O, CH 2 CH 2 CN, CH 2 CH 2 COOH, or alkoxycarbonylethyl, X<SP>2</SP> is H or CH 3 , the OH group being in ortho- or preferably paraposition to the azo bridge are prepared by coupling tetrazotized 4;4<SP>1</SP>-diaminostilbene with one or more phenols in aqueous alkaline medium. The dyes are used to colour synthetic fibres, in particular polyester fibres, in yellow shades.
