Abstract

1506069 Azo indole dyestuffs BAYER AG 18 June 1976 [21 June 1975] 25379/76 Heading C4P Novel azo dyestuffs which are practically insoluble in water have the formula in which D is radical of a diazo component, R 1 is alkyl, R 2 is alkyl or aryl, or R 1 and R 2 conjointly represent the remaining members of a 5- or 6- membered isocyclic ring, R 3 is H or acyl, R 4 is H or alkyl, R 5 is H, or alkyl or aryl, and R 6 is H, halogen, alkyl or alkoxy. D may be a radical of the benzene, thiazole, benzthiazole, thiadiazole, triazole, pyrazole, indazole or thiophene series. The dyes are prepared by diazotization and coupling with an appropriate indole or acyl indole. They are used for dyeing synthetic fibre materials, especially polyamides and particularly polyesters such as polyethyleneterephthalate and poly-1,4- cyclohexane dimethyl terephthalate.
