Abstract
1,264,071. Disazo dyes. FARBENFABRIKEN BAYER A.G. 5 May, 1970 [17 May, 1969], No. 21622/70. Heading C4P. Disazo dyes, which are free from sulphonic acid groups have the formula wherein R 1 represents an aromatic residue or a C 1-4 aliphatic residue; R 2 represents Cl, Br, a C 1-4 aliphatic residue or C 1-4 alkoxy group; R 3 and R 4 represent H, a C 1-4 alkyl group or a C 1- 4 alkoxy group and may be the same or different; R 5 , R 6 and R 7 represent H, a C 1-4 alkyl group, a C 1-4 alkoxy group, halogen, a carboxylic amide group, or a carboxylic acid or ester group and may be the same or different; Y represents a hydroxyl group or an amino group NR 8 R 9 , wherein R 8 and R 9 represent a C 1-4 alkyl residue optionally substituted by a hydroxyl or nitrile group, or a benzyl residue; and n is 0, 1 or 2. The dyes are produced by coupling the diazonium compound from a disulphamide of formula with an amine of formula where Q is H or a residue -CH 2 -SO 3 H or -SO 3 H, diazotizing the monoazo dye produced, after conversion of the group NH-Q into an NH 2 group and coupling the product with a phenol of formula or an aniline derivative of formula
