| titleOfInvention | Monoazo dyestuffs derived from substituted indole coupling components |
| abstract | 1457231 Monoazo dyes derived from indole coupling components BAYER AG 6 May 1975 [28 May 1974] 18967/75 Heading C4P Novel dyestuffs of the formula (wherein D is the radical of an optionally substituted heterocyclic diazo component from the series of 2-amino-1,3-benzthiazole, 3-amino-2,1- benzisothiazole, 5 - amino - 1,2,4 - thiadiazole, 2 - amino - 1,3,4 - thiadiazole and 2 - amino- 1,3,4 - oxadiazole; R 1 is optionally substituted aryl; R 2 is H or optionally substituted alkyl; R 3 is halogen, CF 3 , CN, NO 2 or C 1-4 alkyl or alkoxy; and n is zero, 1,2 or 3; and the sulphogroup can be present in D, R 1 , R 2 or ring A, and when it is present in R 2 it is bonded via oxygen) are prepared by coupling diazotized amines DNH 2 with coupling components of the formula wherein q is zero or 1. They are suitable for dyeing natural or synthetic fibre materials, particularly polyamide fibres, in orange to red shades. |
