Filed Oct. 14, 1960, Ser. No. 62,537 Claims priority, application Germany Oct. 17, 1959 6 Claims. (Cl. 260-146) The present invention relates to new complex metal compounds of water-insoluble azo-dyestuffs; more particularly it relates to complex metal compounds of dyestufis corresponding to the following general formula wherein the quinoline radical may be substituted by halogen atoms, trifluoromethyl, alkyl, alkoxy, aryloxy, sulfonic acid ester, sulfonic acid amide, carboxyiic acid ester, carboxylic acid amide, cyano, acylamino, alkylsulfonic, arylsulfonic or acyl groups, R stands for the radical of an arylamide of an aromatic or heterocyclic ortho-hydroxycarboxylic acid or of an acylaeetic acid being free from water-soluble groups, and n represents the integer l or 2.
We have found that new water-insoluble metalliferous azo-dyestuifs are obtained by coupling in substance, on the fiber or on another substratum the diazonium compounds of 8-aminoquinolines with arylides of aromatic or heterocyclic ortho-hydroxycarboxylic acids or of acrylacetic acids, the components being selected so that they are free from groups imparting solubility in water such, for example, as sulfonic acid or carboxylic acid groups, and treating the dyestuffs so obtained with agents yielding metal.
The treatment of the water-insoluble aZo-dyestuifs 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 metallization may be carried out by adding the agents yielding metal to the developing bath or to the impregnation bath. The treatment of the dyestuffs with agents yielding metal after the coupling may be carried out in a second bath which is neutral, weakly alkaline or weakly acid and may contain dispersing agents or detergents, such, for example, as a fatty alcohol polyglycol ether, an alkylphenol polyglycol ether, an alkylnaphthol polyglycol ether, a fatty acid polyglycol ester or a fatty acid amide polyglycol ether.
As agents yielding metal, there are preferably used for the process of the present invention compounds yielding copper, cobalt, nickel, manganese, zinc, cadmium or iron which may be used in the form of their inorganic or or-' ganic salts such, for example, as chlorides, bromides, sulfates, nitrates, for-mates or acetates, or as complex compounds of these metals, especially with hydroxyalkylamines, such, for example, as triethanolamine, with amino acids such as aminoaceticacid or nitrilotriacetic acid, with hydroxycarboxylic acids, such as citric acid or tartaric acid, or with alkali metal phosphates, such, for example, as alkali pyrophosphates or alkali polyphosphates. When an agent yielding cobalt is used, the addition of compounds of hexavalent chormium or other oxidizing agents,
for example alkali metal perborates or alkali metal persulfates, has an advantageous effect on the metallization. On vegeatable fibers, including fibers of regenerated cellulose, there are obtained by the ice colour method known for dyeing and printing dyestuffs which possess, in addition to good general properties of fastness a very good fastness to light. The claret tints which are obtained by using arylides of 2,3-hydroxynaphthoic acid as coupling components and nickel compounds as agents yielding metal are particularly valuable.
The production of the dyestuffs on vegetable fibers may be carried out at a long goods-to-liquor ratio. Piece goods, warps or bands may be dyed in a continuous man ner, or printed by the base or naphtholate printing process.
The new dyestuffs can also be produced on animal fibers such as wool or silk, or on synthetic fibers such as polyamide, acetylcellulose, or polyvinyl alcohol fibers, by the dyeing processes usual for these fibers, and valuable dyeings possessing good properties of fastness are obtained.
The dyestuffs can also be prepared in substance and converted into complex metal compounds by a treatment with agents yielding metal. The complex metal compounds so obtained are suitable for dyeing synthetic fibers, or for colouring plastic masses of high molecular weight.
As diazo components there can be used for the process of the present invention the S-aminoquinoline or substitution products, thereof, as substituents being used groups which do not impart solubility in water such, for example, as halogen atoms, trifluoromethyl, alkyl, alkoxy, aryloxy, sulfonic acid ester, sulfonic acid amide, carboxylic acid ester, carboxylic acid amide, cyano, acylamino, alkylsulfonic, arylsulfonic, or acyl groups.
As coupling components for the process of the present invention, there can be used arylides of aromatic or heterocyclic ortho-iydroxycarboxylic acids or of acylacetic acids such, for example, as arylides of 2,3-hydroxynaphthoic acid or its derivatives substituted in the 6-position, or arylides o-f Z-hydroxyanthracene-S-carboxylic acid, 3-hydroxydiphenylene oxide-Z-carboxylic acid, Z-hydroxycarbazole-3-carboxylic acid, 5-hydroxy-l,2,1',2'-benzocarbazole-4-carboxylic acid, acetoacetic acid, benzoylacetic acid or terephthaloyl-bis-acetic acid.
The following examples serve to illustrate the invention but they are not intended to limit it thereto, the parts being by weight unless otherwise stated, and the relationship of parts by weight to parts by volume being the same as that of the kilogram to the liter.
Example 1 Cotton yarn is treated for 45 minutes at 35 C. at a goods-to-liquor ratio of 1:20 in the impregnation bath prepared as described below, then centrifuged, and while wet, developed first for some minutes at 20 C. and then, after being slowly heated to C. to 95 C., for 20 to 30 minutes at C. to C. in the developing bath prepared as described below.

Example 8 16.2 parts of 1-(2'.3 hydroxynaphthoylamino)-2- methylbenzene are dissolved in 100 parts of hot water and 75 parts by volume of 2 N-sodium hydroxide solution. The solution is diluted with water to about 400 parts by volume and ice is added in such an amount that the temperature amounts to 0 C. To this solution there is added a mixture of 6.5 parts of crystalline copper sulfate, 30 parts by volume of water, 10 parts of triethanolamine and parts by volume of a 2 N-sodium hydroxide solution, and a diazo solution prepared in usual mannor from 7.2 parts of 8-aminoquinoline is added dropwise, while vigorously stirring, the temperature being maintained at 0 C. by the addition of ice. After the coupling, the complex copper compound is filtered off with suction, Washed and dried. The dyestufi so obtained is a dark red powder.
