| Metal complex dyes comprising a metalizable azo compound represented by one of Formulas [I] through [IV]: ##STR1## In Formulas [I] through [IV], Ps represents a phosphono group in the form of a free acid or a salt; Sf represents a sulfo group in the form of a free acid or a salt; m is 0, 1 or 2. R.sup.1 represents a hydrogen atom or an amino group; X represents a hydroxyl group, an alkoxy group having a carbon number of 1 or 2 or a carboxyl group. Y represents a hydroxyl group, an alkoxy group having a carbon number of 1 or 2, a carboxyl group or a methyl group; R.sup.2 represents a hydrogen atom or a hydroxyl group; A represents a phenyl group or naphthyl group selected from the group comprising the following 1 through 4: ##STR2## In the above formulas 1 through 4, Sf has the same definition as above; n is 0, 1 or 2. R.sup.3 represents a hydroxyl group or a carboxyl group; R.sup.4 represents a hydroxyl group, a carboxyl group or an amino group; R.sup.5 and R.sup.6 independently represent a hydroxyl group or a carboxyl group; R.sup.7 and R.sup.8 independently represent a hydrogen atom, a hydroxyl group or an amino group. B has the same definition as A above except that R.sup.3 represents a hydroxyl group, a carboxyl group or an amino group. R.sup.9 represents a hydrogen atom, a methyl group, an alkoxy group having a carbon number of 1 or 2 or a sulfo group in the form of a free acid or a salt; D represents a coupling component residue having a metalizable hydroxyl group at the position adjoining to the azo group.Use of these metal complex dyes makes it possible to dye metal-tanned leather with good permeability and excellent color fastness to rubbing and color fastness to light. | ||||||

| New trisazo compounds that are useful as developed direct black dyes for cellulosic textiles and as self-shade dyes for paper and leather having the structure: ##STR1## wherein R' is at least one of the following groups: ##STR2## and M is H, Na, K, Li, N(R).sub.3 H where R is H, lower alkyl or lower hydroxyalkyl and each of the R groups can be the same or different. | ||||||

| Azo dyestuffs, which in the acid form, are represented by the formula:A -- N .dbd. N -- M -- N .dbd. N -- E (1)whereinA is an aromatic radical,M is a 1,4-benzene radical which may be substituted,E is the residue of a coupling component which is free from azo groups,At least one of A and M containing a phosphonic acid group, and the metal complexes of those having a metallisable group are reactive dyes suitable for use in the process of German OLS No. 2324809. | ||||||
