Abstract

1,251,460. Disazo dyes. CROMPTON & KNOWLES CORP. 13 April, 1970 [14 April, 1969; 19 Sept., 1969], No. 17520/70. Heading C4P. The invention comprises dyes having the formula wherein M is -H, -Na, -K, or -NH 4 ; R 1 is -H, -CH 3 , -OCH 3 or -Cl; and R 2 is -H, -CH 3 , -OCH 3 . The dyes are prepared by diazolizing aniline, a toluidine, an anisidine or a chloroaniline, coupling with 1-naphthylamine, rediazotizing the aminomonoazo intermediate and coupling with an N-aryl peri-acid. The dyes are used for dyeing natural and synthetic polyamide fibres and synthetic polyurethane fibres in light-fast navy blue shades.
