| titleOfInvention | Metallized bis-formazans |
| abstract | Heavy-metal-containing bisformazan dyestuffs of the formula <IMAGE> (I) <IMAGE> WHEREIN A1, A2, B1 and B2 are the same or different and each represents an unsubstituted or substituted o-phenylene radical or an o-naphthylene radical, R1 and R2 are the same or different and each represent a monovalent organic radical, Me1 and Me2 each represent nickel or copper, X1 and X2 are the same or different and each represents a metal-binding substituent connected to A1, B1, A2 or B2 in a position ortho to that to which the nitrogen is linked, Y represents the radical of a dibasic carboxylic acid or a radical which is derived from an, at least, bifunctional heterocyclic compound, Z represents a salt-forming water-solubilizing group, dissociating acid in water, selected from -SO3(-)M(+) and -COO(-)M(+)wherein M(+) represents a cation, N REPRESENTS A NUMBER FROM 2 TO 6, AND WHEREIN AROMATIC RADICALS PRESENT MAY CONTAIN FURTHER SUBSTITUENTS KNOWN PER SE FOR USE IN AZO DYESTUFFS, AND WHEREIN THE GROUPING -NH-Y-HN- is bound directly or via a bridging member to a ring carbon atom of A1, A2, B1, B2, R1 or R2 , which bis-formazans are substantive dyestuffs suitable for the dyeing or printing of textile material made from natural or regenerated cellulose. The aforesaid bis-formazan dyestuffs are distinguished by high coloring strength and substantivity to cellulose textile material. The dyeings obtained therewith are of a pure shade of color and have good fastness properties, especially to light and wet. |
