The dyes may be obtained from 1,4-diamino-5-hydroxy-8-nitroanthraquinones of the formula IV by the following methods:

02N O NH I NII H0 O NE-Y Acylation Reduction 02N O H,N O cc HO 0 blH-Y HO 0 NH-Y (V) (VI, Reduction | Acylation 9 O 0 H2N O lmi-C-R R-C-HN O llH 1 (Ib) (Ic) In the formulae Ib, Ic, IV, V and VI, Y and R have the above meanings.

The required starting compounds IV may be obtained by condensing l-amino 8-nitro-4,5-dihydroxyanthraquinone with an amine of the general formula Y-NH2 by the process described in German Laid-Open Application DOS 2,029,793.

The compounds of the formula IV are either converted to the 1-acylamino-4amino-5-hydroxy-2-nitroanthraquinones (V) by reaction with acylating agents and then reduced to the 1-acylamino-4,8-diamino-5'-hydroxy-anthraquinones (Ib), or they are first reduced to the 1,4,8-triamino-5-hydroxy-anthraquinones (VI) and then reacted with acylating agents to give the 1,4-diamino-5-hydroxy-8-acylamino anthraquinones (Ic).

The acylation is advantageously carried out by suspending the compounds of the formula IV or VI in an organic liquid which is inert under the reaction conditions, heating the suspension to the reaction temperature and adding the acylating agent dropwise, whilst stirring. Alternatively, the acylating agents may be added to the suspension at room temperature and the mixture then heated to the reaction tem perature. Normally, from 1.0 to 2.0 moles, preferably from 1.1 to 1.5 moles, of acylating agent are used per mole of the compound to be acylated. The acrylaticn is advantageously carried out at from room temperature to 170"C, preferably at from 50 to 1500 C. At these temperatures, the reaction is in general complete after from 0.2 to 6 hours.

The acylation of compounds (VI) is advantageously carried out in the presence of at least the stoichiometric amount of a tertiary amine, e.g. triethylamine.

Suitable acylating agents are e.g. carboxylic acid esters and preferably carboxylic acid chlorides, phenyl isocyanates, chloroformic acid esters and acid chlorides of dicarboxylic acid half-esters.

The reduction of compounds of the formula IV or V may be carried out by conventional methods, e.g. with Na2S in aqueous suspension. Preferably, however, the nitro compounds IV or V are reduced with hydrazine hydrate in an inert organic liquid. This reducing agent has the advantage that the acylation and the reduction, or the reduction and the acylation, can be carried out in a one-vessel reaction, since the same inert organic liquid can be used for both reactions.

Normally, the reduction is carried out by heating a suspension or solution of the nitro compound in the inert organic liquid to the reaction temperature and then adding the hydrazine hydrate dropwise, whilst stirring. Advantageously, the reduction is carried out at from 50 to 1700C, preferably from 80 to 1500C, using from 1.5 to 3.5 moles, preferably from 1.5 to 2.0 moles, of hydrazine hydrate per mole of nitro compound. Under these conditions, the reaction is normally complete after from 0.5 to 6 hours.

Examples of organic liquids which are inert under the reaction conditions are aliphatic chlorohydrocarbons, e.g. chloroform, methylene chloride, carbon tetrachloride, dichloroethane, tetracbloroethane and trichloroethane, aromatic hyldrocarbons, e.g.

toluene and xylene and preferably aromatic chlorohydrocarbons, e.g. chlorobenzene, o-dichlorobenzene and trichlorobenzene; carboxylic acid N,N-dialkylamides, e.g. N,Ndimethylformamide, N,N-dimethylacetamide, N,N-dimethylpropionamide, N-methylpyrrolidone, nitrobenzene and pyridine.

The amount of organic liquid used is such that the reaction mixture can be stirred or mixed; in general, a 2.5-fold to 15-fold amount by weight, based on the compound to be acylated or reduced, suffices.

To work up the reaction mixture, it may be cooled to room temperature and, if necessary, the reaction product is precipitated by adding a diluent which only dissolves the reaction product slightly, if at all, after which the product may be isolated in the conventional manner.

According to their structure, the dyes according to the invention should exhibit the properties of disperse dyes. However, their affinity for polyester is too low for this purpose. German Patent 1,811,796 discloses a process by means of which dyes which are insoluble or sparingly soluble in water can be printed on cellulose or cellulosecontaining textile material using a carrier, sometimes referred to as a swelling agent, which is usually an oxyethylene compound such as ethylene glycol or a derivative thereof. The information on process conditions given in German Patent 1,811,796 also applies to the dyes according to the invention. Generally the fibres are contacted with water and an oxyethylene swelling agent and, simultaneously or successively while the fibres are still swollen, with the dye.

German Laid-Open Applications DOS 2,524,243 and 2,528,743 disclose other processes by means of which the dyes according to the invention may be applied.

Amongst these, printing processes are preferred.

Accordingly the present invention also provides a process for dyeing cellulose or cellulose-containing fiber material with a dye according to the invention wherein the dyeing is carried out in the presence of a swelling agent, especially a glycol, to assist of the dye from an aqueous phase onto the material, and materials dyed thereby.

For use in the above dyeing processes, the dyes according to the invention are advantageously converted to aqueous formulations. These contain the dye in a finely dispersed form, in addition to one or more dispersants, one or more water-retaining agents and one or more auxiliaries conventionally used in aqueous formulations, e.g.

one or more disinfectants.

Such formulations are advantageously produced by milling a suspension of from 15 to 40, preferably from 20 to 35, parts of dye (I), from 4 to 10 parts of dispersant, from 5 to 15 parts of water-retaining agent and from about 0.5 to 1.5 parts of disinfectant in from about 75.5 to 33.5 parts of water in a stirred ball mill, a bead mill or a sand mill until the particle size is about 0.5 /lm or less. Storage-stable dye dispersions are thus obtained.

Suitable dispersants are the anionic and non-ionic dispersants conventionally used for the preparation of finely divided formulations of disperse dyes. Examples of anionic dispersants include ligninsulfonates, salts of phenol/formaldehyde/sodium sulfite condensation products (German Laid-Open Application DOS 2,301,638), salts of 2-naphthalenesulfonic acid/formaldehyde condensation products, salts of phenol suifonic acid/urea/lormaldehyde condensation products, and salts of condensation products of phenolsulfonic acid/urea/formaldehyde, which have been post-condensed with phenol and formaldehyde.

Suitable non-ionic dispersants include, above all, ethylene oxide adducts and propylene oxide/ethylene oxide adducts. These are described in, for example, U.S.

Patents 2,979,528 and 3,841,888.

The amount of dispersant depends on the dye and on its concentration in the dispersion. As a rule, it is fro m4 to 10 per cent by weight, based on the formaulation.

Suitable water-retaining agents include, especially, glycols, e.g. ethylene glycol, propylene glycol, diethylene glycol and preferably dipropylene glycol. The amount used is in general from 5 to 15, preferably from 8 to 12, per cent by weight based on the formulation.

The Examples which follow illustrate the invention.

EXAMPLE 1.

19.5 parts of 1-amino-4-m-toluidino-5-hydroxy-8-nitroanthraquinone are sus pended in 100 parts of o-dichlorobenzene, 10.2 parts of butyl chlorocarbonate are added and the mixture is heated to 140"C, whilst stirring, and kept at from 140 to 1500C until starting material is no longer detectable (duration: 3 hours). 7.5 parts of 100% strength hydrazine hydrate are then added dropwise in the course of 20 minutes. This causes the temperature of the reaction mixture to drop to 120 1300C. The mixture is kept at this temperature for 1 hour and is then cooled to 70"C, and 120 parts of methanol are added.After the mixture has cooled to room temperature, the reaction product which has precipitated is filtered off, washed with methanol and hot water and dried. 14 parts of 1-butoxycarbonylamino-4-m-toluidino- S-hydroxy-8-amino-anthraquinone are obtained On cotton, blue dyeings are obtained.

It is then cooled to 800C and 320 parts of methanol are run in. After the mixture has cooled to room temperature, the reaction product which has precipitated is filtered off, washed with methanol and finally with hot water, and dried. 14 parts of 1methoxycarbonylamino - 4 - [1 - phenylethylamino - (1) j - 5 - hydroxy - 8 - aminoanthraquinone are obtained.

After stirring for 2 hours at from 120 to 1300C, 7.1 parts of methyl chlorocarbonate are added and the reaction mixture is stirred for a further 1.5 hours at the same temperature. It is then allowed to cool to 800C and the reaction product is precipitated with 320 parts of methanol. Working up takes place in the manner described in Example 1. 14 parts of 1-amino-4-[1-phenylethylamino-(1)]-5-hydroxy-8-methoxy- carbonylamino-anthraquinone are obtained.
