Examples of aromatic radicals R are phenyl and p-chlorophenyl.

A compound of the formula I may be prepared by introducing the radical R by a conventional method into a compound of the formula II ##STR10## For example, for aralkylation of the phenolic OH it is possible to use unsubstituted and substituted aralkyl chlorides and bromides and unsubstituted and substituted diaralkyl sulfates.

The etherification is carried out in a conventional manner, for example in an aqueous alkaline medium, in an aqueous-organic alkaline medium or under anhydrous conditions in an organic solvent in the presence of an acid acceptor. The reaction is most advantageously carried out at from 50.degree. to 160.degree. C., where necessary, in the case of low-boiling solvents, in an autoclave.

A further method of preparation of a dye of the formula I is the conventional acylation of a compound of the formula III ##STR11##

Details of the preparation may be found in the Examples, where parts and percentages are by weight, unless stated otherwise.

Suitable dyeing processes for applying a dye of the formula I are, in particular, those described in German Pat. No. 1,811,796 and German Laid-Open Applications Nos. 2,524,243, 2,528,743 and 2,855,188.

Industrially particularly valuable compounds are those of the general formula I a ##STR12## where B.sup.1 is hydrogen, chlorine, methyl, ethyl, phenyl, methoxy or ethoxy, B.sup.2 is hydrogen, chlorine or methyl, B.sup.3 is hydrogen, chlorine, methyl, ethyl, acetylamino or C.sub.1 -C.sub.4 -alkoxy, B.sup.4 is hydrogen, methyl or C.sub.1 -C.sub.4 -alkoxy, B.sup.3 and B.sup.4 together may also be a fused benzo ring, B.sup.5 is hydrogen, methyl, chlorine or C.sub.1 -C.sub.4 -alkoxy, B.sup.6 is hydrogen, methyl or C.sub.1 -C.sub.4 -alkoxy, X.sup.3 is C.sub.1 -C.sub.8 -alkanoyl or benzoyl, X.sup.4 is hydrogen, C.sub.1 -C.sub.4 -alkyl or phenyl, X.sup.3 and X.sup.4 together may also be a radical of the formula ##STR13## and R has the stated meanings.

Examples of preferred radicals X.sup.3 are --COH, --COCH.sub.3, --COC.sub.2 H.sub.5, --COC.sub.3 H.sub.7, --CO.sub.2 CH.sub.3, --CO.sub.2 C.sub.2 H.sub.5 and --CON(CH.sub.3).sub.2.

Examples of preferred radicals R are CH.sub.2 --C.sub.6 H.sub.5, --CH.sub.2 --C.sub.6 H.sub.4 Cl, --C.sub.2 H.sub.4 --C.sub.6 H.sub.5, --C.sub.2 H.sub.4 O--C.sub.6 H.sub.5, --C.sub.2 H.sub.4 OC.sub.2 H.sub.4 OC.sub.6 H.sub.5, --C.sub.6 H.sub.5 and C.sub.6 H.sub.4 Cl.

The .lambda..sub.max values mentioned in the Examples which follow were measured in dimethylformamide and are in nm.

EXAMPLE 1

33 parts of the dye of the formula ##STR14## 42 parts of potassium carbonate, 51 parts by volume of 2-phenylethyl bromide and 0.4 part of potassium iodide in 225 parts by volume of N-methylpyrrolidone are stirred for 6 hours at 120.degree. C. The batch is poured into 600 parts of methanol, and the product is precipitated with 1,000 parts of water, these operations being carried out at room temperature. After filtering off the product, washing it with water and drying it, 38 parts of the dye of the formula ##STR15## are obtained.

10 parts of this dye are mixed with 100 parts of polyethylene oxide of molecular weight 300 and 790 parts of a 3 percent strength alginate thickener to give an ink; a 65:35 (by weight) polyester/cotton union fabric is printed with this ink by rotary screen printing and is then dried at 100.degree. C. Thereafter, the fabric is treated for 2 minutes with live steam at 200.degree. C., rinsed cold, soaped at the boil, again rinsed cold and dried. A lightfast, washfast, solvent-fast and sublimation-fast yellowish orange print on a white ground is obtained. Printing on a pure cotton fabric gives a similar result.

.lambda..sub.max : 402

EXAMPLE 2

22.8 parts of the dye of the formula ##STR16## 20.9 parts of potassium carbonate and 25 parts of benzyl chloride in 150 parts of N-methylpyrrolidone are stirred for 4 hours at 110.degree. C. 600 parts of methanol are then added to the batch at room temperature, and the precipitate is filtered off, washed with methanol and water and dried. 17 parts of the dye of the formula ##STR17## are obtained.

A fabric of 65 parts of polyester fibers and 35 parts of mercerized cotton is impregnated with a liquor which contains 10 g/l of a 20% strength liquid formulation of the above disperse dye and 80 g/l of a swelling agent and dye solvent comprising a mixture of 3 parts of polyethylene glycol of molecular weight 1,500 and 1 part of an adduct of one mole of neopentanediamine with 15.6 moles of ethylene oxide. The pH of the padding liquor is brought to 6 with glutaric acid. The fabric is impregnated with the padding liquor at a wet pick-up of 45%. It is then dried for 60 seconds at 120.degree. C. and fixed for 90 seconds at 225.degree. C. in a laboratory model of continuous dryer. The fabric is then rinsed cold and warm and washed for 5 minutes at 100.degree. C. in the presence of a commercial detergent. Fixing of the dye to the fabric is virtually complete. A golden yellow dyeing having good lightfastness, wash-fastness and fastness to crocking is obtained.

.lambda..sub.max : 410

EXAMPLE 3

25 parts of the dye of the formula ##STR18## in 100 parts by volume of propionic anhydride containing 2 parts of 4-dimethylaminopyridine are stirred at 110.degree.-120.degree. C. until the starting material is no longer detectable by thin layer chromatography. The product is filtered off at room temperature, washed with methanol and dried under reduced pressure at 60.degree. C. 15.5 parts of the dye of the formula ##STR19## are obtained.

When used in the dyeing process described in the preceding Example, this dye is virtually completely fixed to the fabric. The dyeing is reddish orange and has good lightfastness and washfastness.

.lambda..sub.max : 380

The dyes shown in the Table are obtained similarly and can be used, by the stated methods, to dye and print cotton and union fabrics, on which they give dyeings having good fastness characteristics.

The dyes mentioned in the Tables which follow can be converted to a commercially useful dye formulation as follows: 30 parts of dye, 6 parts of dispersant, 10 parts of humectant, 1 part of disinfectant and about 53 parts of water are milled in a stirred ball until the particle size is about 0.5 .mu.m. The resulting dye dispersion has a good shelf life.

The substituents X.sup.1, X.sup.2 and T.sup.1 -T.sup.6 of the dyes listed in the Table which follows, and the positional indices shown in various columns of the Table, correspond to the formula IV ##STR20##
