Abstract: The invention comprises acid dyestuffs of the formula (I) where A is hydrogen, halogen, alkyl, alkoxy, carboxylic acid or sulphonic acid, R is hydrogen, alkyl, hydroxyalkyl or alkoxyalkyl, and each of R1 and R2 is hydrogen, halogen or alkyl, and in which A+R+R1+R2 together do not contain more than six carbon atoms and the two -NH-groups are meta or para to each other. The dyestuffs are made by reacting a compound of the formula (II) where A and R are as above, obtainable from a 1 - amino - 4 - halogenanthraquinone - 2 - sulphonic acid and an appropriately substituted meta- or para-phenylene diamine, with a carboxylic acid halide or anhydride of the formula (III) where X is halogen or an acyloxy radical containing an acyl group shown in formula III so that A+R+R1+R2 contain together not more than six carbon atoms. The dyestuffs dye animal fibres such as wool blue shades. Specification 282,409 is referred to.
