Compounds of formulae VIII and IX are known or may be made by known methods from known compounds.
Coupling to form compounds of formula I can be carried out according to known methods.
Advantageously, coupling is carried out in aqueous (acid, neutral or alkali) medium at a temperature from -10"C to room temperature, if necessary, in the presence of a coupling accelerator such as pyridine or urea.
Alternatively, coupling may be effected in a mixture of solvents, for example, water and an organic solvent.
Metallisation of the compounds of formula I can be achieved by known methods.
The disazo compounds offormula I in 1:1 metal complex form maybe prepared by metallising compounds of formula I in metal-free form with a metal selected from copper, cobalt, iron, nickel, manganese, chromium and zinc.
The disazo compounds of formula I in 1:2 metal complex form may be prepared by metallising compounds of formula I in metal-free form with a metal selected from chromium, nickel, cobalt and iron.
A further method for the preparation of a disazo compound of formula I in 1:2 metal complex form is by reacting a compound of formula I or other than formula I in metal-free form with a disazo compound 1:1 metal complex of formula I when the metal is chromium, nickel, cobalt or iron.
The metallisation process to form a 1:1 metal complex of the type of formula VI is advantageously carried out by treating 1 mole of a disazo compound with a metallising agent containing 1 equivalent of metal.
1:1 Metal complex formation using copper can be carried out by directly reacting a compound of formula I with metal salt or by oxidative coppering preferably at 40-70 C and at a pH of 4-7 in the presence of a Cu(ll) salt or with copper filings in the presence of H202 or any other oxidating material; or demethylating coppering can be applied in a pH range of 3-4 at a high temperature.
Metallisation is carried out advantageously in aqueous medium or in a mixture of water and a water-miscible organic solvent, for example acetone, lower alkyl alcohols, dimethylformamide, formamide, glycols or acetic acid at a pH range from 1.0 to 8.0, preferably pH 2 to 7. The metallisation process may be carried out at a temperature from room temperature to the boiling point of the reaction medium.
Alternatively, metallisation may be effected in a wholly organic medium (for example dimethylformamide). Advantageously, for instance, cobaltisation may be carried out in the presence of an inorganic nitrite such as lithium, sodium, ammonium or potassium nitrite in the ratio of 2 to 6 moles of nitrite per atom gram of cobalt.
Suitable cobalt-yielding compounds are, for example, cobalt(ll) or Co(lll) sulphate, acetate, formate or chloride.
Copper-yielding compounds are, for example cupric sulphate, cupricformate, cupric acetate and cupric chloride.
The nickel-yielding compounds are Ni(ll) or Ni(lll) compounds, such as nickel formate, nickel acetate and nickel sulphate.
Preferred manganese-yielding compounds are Mn(ll) compounds and iron-yielding compounds are Fe(ll) or Fe(lil) compounds. Examples of these and zinc-yielding compounds are manganese, iron and zinc formate, acetate and sulphate.
Preferred chromium-yielding compounds are Cr(ll) and Cr(lll) formate, acetate and sulphate.
In the compounds of formula I the anions As can be any non-chromophoric anions such as those conventional in basic dyestuff chemistry. Suitable anions include chloride, bromide, sulphate, bisulphate, methylsulphate, aminosulphonate, perchlorate, benzenesulphonate, oxalate, maleate, acetate, propionate, lactate, succinate, tartrate, malate, methane sulphonate and benzoate as well as complex anions, for example zinc chloride double salts and anions of boric acid, citric acid, glycollic acid, diglycollic acid and adipic acid or addition products of ortho boric acids with polyalcohols with at least one cis diol group present. These anions can be exchanged for each other by iron exchange resins on reaction with acids or salts (for example via the hydroxide or bicarbonate) or according to German Offenlegungsschrift 2,001,748 or 2,001,816.
The compounds of formula I are suitable for dyeing, padding or printing fibres, threads or textile materials, particularly natural or regenerated cellulose materials for example cotton, polyester or synthetic polyamides modified by anionic groups. Such a polyamide is described in Belgian Patent 3,379,723.
The compounds of formula I are also used for dyeing, padding or printing fibres, threads or textiles produced therefrom which consist of or contain homo- or mixed polymers of acrylonitrile or of 1,1-dicyanoethylene.
The textile material is dyed, printed or pad-dyed in accordance with known methods. Acid modifiedpolyamide is dyed particularly advantageously in an aqueous, neutral or acid medium, at temperatures of 60"C to boiling point or at temperatures above 1 000C under pressure.
The textile material may also be dyed by the compounds of formula I in organic solvents, e.g. in accordance with the directions given in German Offenlegungsschrift 2,437,549.
Cellulose material is mainly dyed by the exhaust process, i.e. from a long or short bath, at room temperature to boiling temperature, optionally under pressure, whereby the ratio of the bath is from 1:1 to 1:100 and preferably from 1:20 to 1:50. If dyeing is effected from a short bath, then the liquor ratio is 1:5 to 1:15. The pH of the dye-bath varies between 3 and 10 (for short and long dyebaths).
Printing may be effected in accordance with known methods.
The dyestuffs of formula I are particularly suitable for dyeing or printing paper, e.g. for the production of bulk-dyed, sized and unsized paper. The dyestuffs may similarly be used for dyeing paper by the dipping process. The dyeing of paper is effected by known methods. The compounds of formula I are especially suitable for dyeing ligneous paper, particularly paper with mechanical wood pulp.
The azo compounds of formula I may also be applied to bast fibres such as hemp, flax, sisal, jute, coir or straw.
The dyestuffs of formula I are also suitable for dyeing or printing leather by known methods and dyeings with good fastness properties are obtained.
Dyeings prepared with dyestuffs of formula I on paper produce a substantially clear waste liquor which is important for environmental reasons. The dyestuffs of formula I have good build-up properties, do not bleed once applied to paper and are not pH sensitive. They have a high affinity for paper and do not mottle on ligneous paper. Dyeings produced with dyestuffs of formula I have good light fastness and the nuance on exposure for a long time to light fades tone in tone. The dyestuffs of formula I have good wetfastness properties not only for water but also for milk, soap, water, sodium chloride solution, fruit juice and sweetened mineral water. Further dyeings made with dyestuffs of formula I are fast for alcoholic beverages due to a good alcohol fastness. Further, the dyestuffs of formula I have good nuance stability.
The compounds of formula I are advantageously used in their acid addition salt form, e.g. a salt produced by addition of a carboxylic acid such as acetic acid, lactic acid, formic acid, methoxy or ethoxy acetic acid or glycollic acid, or quaternary ammonium salt form.
For their use the azo compounds of formula I are suitably worked up into stable solid or liquid preparations, according to known methods, advantageously by grinding or granulating or by dissolving in suitable solvents, optionally adding an assistant, e.g. a stabiliser, a solubilising or a diluting agent such as urea. Such preparations may be obtained, for example, as described in French Patent Specifications 1,572,030 and 1,581,900 or in accordance with German DOS 2,001,748 and 2,001,816.
Liquid dyeing compositions are preferably as follows: 1 part by weight of a compound of formula I (in acid addition salt form or quaternary ammonium salt form); 0.01-1 part by weight of an inorganic salt (preferably 0.1 to 0.1 parts); 0.01-1 part by weight of an organic acid such as formic, acetic lactic, citric, propionic or methoxy acetic acid; 1-8 part by weight of water; and 0-5 parts by weight of a solubilising agent such as a glycol (diethylene glycol, triethylene glycol or hexylene glycol), a glycol ether such as methyl cellosolve methylcarbitol, butylpolyglycol, urea, formamide and dimethylformamide.
Solid dyeing preparations are as follows: 1 part by weight of a compound of formula I (in acid addition salt form or quaternary ammonium salt form) 0.01-1 part by weight of an inorganic salt (preferably 0.01 to 0.1 parts) 0 - 8 parts by weight of a diluting agent such as urea, dextrin, glucose or d-glucose).
The solid compositions may usually contain up to 10% water.
The invention will now be illustrated by the following Examples in which all parts are by weight and all temperatures are in degrees Celsius.
Example 1 19.8 Parts (0.1 M) of 4,4'-diaminodiphenylmethane are tetrazotised according to known methods with 13.8 parts (0.2 M) of sodium nitrite at 0-5 in 200 parts of water and 60 parts of 30% hydrochloric acid. 64.4 Parts (0.2 M) of a compound of formula
dissolved in 250 parts of water are added over 30 minutes to the ice cold tetrazotised solution. By the addition of a 30% NaOH solution the pH is brought to 4.5. The resulting dyestuff is of formula 1 b
and is in solution.
By concentration under vacuum or by precipitation in acetone/alcohol the dyestuff is isolated.
The reaction mixture however can be used directly for dyeing without isolating the product.
The dyestuff of formula 1 b has a high solubility in water and gives yellow dyeings with good fastness properties.

Application Example F 15 kg waste paper, 25 kg bleached mechanical pulp and 10 kg unbleached sulphate cellulose are defibrated in a pulper into a 3% aqueous pulp slurry. This stock suspension is diluted to 2% in a dyeing chest. To this diluted suspension there are added at first 5% by weight china clay and then 1,25 kg of a 5% acetic adid solution of the dyestuff of Example 1, the % being based on the dry weight of fibres. After 20 minutes, a 1% resin size dispersion (based on the weight of absolutely dry fibres) is added to the resulting pulp in the mixing chest. The homogeneous pulp slurry is then adjusted to pH 5 by addition of alum shortly before introduction into the paper machine.
A yellow 80 g/cm2 heavy bag paper is produced on the paper machine. The resulting dyed paper exhibits very good fastness properties to bleeding according to DIN 53 991 and good light fastness properties.
The resulting paper can almost completely be decolourized by hypochlorite.
Example G Water is added to a dry pulp in a hollander consisting of 60% by weight of mechanical wood pulp and 40% by weight of unbleached sulphite cellulose and the slurry is beaten in order to obtain a dry content slightly exceeding 2.5% and having a beating degree of 40 SR. The slurry is then exactly adjusted to a high density dry content of 2.5%.
5 Parts of a 0.25% aqueous solution of the dyestuff of Example 1 are added to 200 parts of the above resulting slurry. The mixture is stirred for about 5 minutes and, after addition of 2% by weight resin size and then 4% by weight alum (based on the dry weight) is further stirred for a few minutes until homogeneous.
The resulting pulp is diluted with about 500 parts water to a volume of 700 parts and then used for the production of sheets by succion on a sheet former. The resulting paper sheets are dyed in an intense yellow shade. The residual dyestuff concentration in the waste water from the sheet former has been measured photometrically (A max. = 448 nm) and is substantially low.
Any one of the dyestuffs of Examples 2 to 81 may be used in place of that of Example 1 in any one of Application Examples F and G. The waste water exhibits a substantially low residual dyestuff concentration.
