United States Patent 3,099,651 WATER-INSOLUBLE MONO- AND DISAZO-DYES PRODUCED FROM Z-AMHNOARYL-BENZTRIA- ZOLE-l-OXIDE DIAZO COMPONENTS Richard Gross, Frankfurt am Main, and Hasso Hertel, Werner Kirst, and Reinhard Mohr, Offenbach (Main), Germany, assignors to Farbwerke Hoechst Aktiengesellschaft vormals Meister Lucius & Briining, Frankfurt am Main, Germany, a corporation of Germany No Drawing. Filed May 17, 1960, Ser. No. 29,577 Claims priority, application Germany May 20, 1959 6 Claims. (Cl. 260-1l46) The present invention relates to new water-insoluble azo-dyestuffs containing metal and to a process for preparing them; more particularly it relates to water-insoluble azo-dyestuffs containing metal which, when free from metal, correspond to the following general formula wherein A and B represent radicals of the benzene or naphthalene series and R represents the radical of an arylamide of an aromatic or heterocyclic ortho-hydroxycarboxylic acid or an acylacetic acid.
We have found that new water-insoluble azo-dyestufls containing metal are obtained by coupling in substance, on the fiber or on another substratum the diazonium compounds of amines corresponding to the general formula wherein A and B represent radicals of the benzene or naphthalene series, with arylamides of aromatic or heterocyclic ortho-hydroxycarhoxylic acids or acylacetic acids, the diazo and coupling components containing no groups imparting solubility in water such, for example, as sulfonic acid or carboxylic acid groups, and treating the dyestuffs thus obtained with agents yielding metal.
The treatment of the water-insoluble azo-dyestufis obtainable according to the process of this invention with the agents yielding metal may be carried out by known methods during or after the coupling in substance or on the fiber. When the dyestuffs are produced on the fiber, the motallisation may be effected by adding the agents yielding metal to the developing bath or by adding these compounds already to the impregnation bath. The treatment of the dyestuifs with agents yielding metal after the coupling may be carried out in a second bath which is neutral, weakly alkaline or Weakly acid and contains, if desired, dispersing agents and detergents, such as for example fatty alcohol polyglycolether, alkylphenol-polyglycolether, alkylnaphthol-polyglycolether, fatty acid polyglycolester or fatty acid amide polyglycolether.
As agents yielding metal, there may be preferably used for the process of the present invention agents yielding copper, cobalt and nickel which may be applied in the form of their inorganic or organic salts such as, for example, chlorides, bromides, sulfates, nitrates, formates or acetates, or as complex compounds, in particular with hydroxy-alkylamines, such for example as triethanolamine, with amino acids such as amino acetic acid or ice nitrilotriacetic acid, with hydroxy-carboxylic acids, such as citric acid or tartaric acid, or with alkali metal phosphates, such for example, as allcali-pyrophosphates or alkali-polyphosphates. When there is used an agent yielding cobalt, the addition of compounds of hexavalent chromium or other oxidizing agents, for example alkali metal perborates or alkali metal persulfates, proves to be favorable for the metallisartion. On vegetable fibers, including fibers of regenerated cellulose, there are obtained by dyeing and printing methods known from the ice color industry dyestuffs which, besides good general properties of fastness, possess a very good fastness to light. The brown tints obtainable with the use of arylamides of 2,3- hydroxy-naphthoic acid as coupling components and copper compounds as agents yielding metal are of particular value.
On vegetable fibers the dyestuffs may be prepared in long goods-to-liquor ratios. Piece goods, warps or bands may furthermore be dyed in a continuous manner, or by the base or naphtholate printing process.
The new dyestuffs may also be prepared on animal fibers such as wool or silk, as well as on synthetic fibers such as polyamide, acetyl-cellulose, or polyvinyl-alcohol fibers by the dyeing processes which are usual for these fibers whereby there are also obtained valuable dyeings possessing good properties of fastness.
The dyestuifs may also be prepared in substance and converted into complex metal compounds by a treatment with agents yielding metal. The metallisation may be etfected in an aqueous suspension, it is suitable, however, to eifect the metallisation in organic solvents, such for example, as acetone or dimethylformamide. The complex metal com-pounds thus obtained are suitable for dyeing animal and synthetic fibers as well as for coloring organic plastic masses of high molecular weight.
As coupling components for the process of the present invention, there may be used arylamides of aromatic or heterocyclic ortho-hydroxy-car-boxylic acids or acylacetic acids, such as the arylamides of 2,3-hydroxy-naphthoic acid or its derivatives substituted in 6-position, furthermore the arylamides of 2-hydroxy-anthracene-3-carboxylic acid, 3-hydroxy-dipl1enylene oxide-Z-carboxylic acid, 2-hydroxy-carbazole-3-carboxylic acid, 5-hydroxy-1,2,1, 2'-benzocarbazole-4-carboxylic acid, acetoacetic acid, benzoylacetic acid or terephthaloyl-bis-acetic acid.
As amino compounds which correspond to the above formula and may advantageously be used for the process of the present invention, there may be used compounds wherein the benzene or naphthalene radicals A and B may be substituted by groups which do not impart solubility in water such as halogen atoms, alkyl, alkoxy, aryloxy, arylamino, trifluoromethyl, sulfonic acid amide, or carboxylic acid amide groups. These amino compounds may be prepared according to the process described in US. patent application Serial No. 13,710 filed March 9, 1960 (now abandoned), and German Auslegeschrift 1,088,060.
