Abstract: IN WHICH D represents the residue of a diazo component of the benzene series bound to the azo bridge in vicinal position to the hydroxyl group and A represents the residue of an acetoacetamide which is bound to the azo bridge in vicinal position to the enolized keto group; the new dyestuffs are especially valuable for dyeing wool and leather and yield brown dyeings of good general fastness properties such as light, washing, perspiration, dry and wet rubbing, and great tinctorial strength.

IN WHICH ONE X represents a nitro group and the other X a sulphonic acid group, and the other corresponds to the formula

The invention relates to metal compounds which contain one molecule each of two different monoazo dyestuffs, one of which corresponds to the formula
