Abstract
The dyes are of formula: (in which R1 is alkyl or aryl, R2 is H or alkyl, R3 is H, halogen or alkyl, R4 is as R3, cyan or alkoxy, p, m are 0 or 1 and p+m is 1 or 2, n is 1 or 2. Ring A may contain other substits. free of -SO3H or -OSO3H gps.). suitable alkyl gps. contain 1-8 (1-4) C atoms, which in the case of R2 may be substd. by CN, CONH2 or COOH. Prefd. dyes contain 1 SO3H substit. in one or other of the benzene rings. The dyes are suitable for use on natural or synthetic fibres esp. polyamides, giving yellow to orange, intense, level shades with very good light fastness.
