The new dyestuffs of the formula I, optionally also as mixtures with one another, are outstandingly suitable for dyeing and/or printing fibres, filaments, woven fabrics, knitted fabrics, tapes, films or sheets of synthetic origin, but above all for dyeing and printing synthetic fibre materials; for the latter purpose, they are employed in accordance with the aqueous dyeing processes customary for these fibres.
Those dyestuffs of the formula I which, because of hydrophobic groups, especially straight-chain or branched C4 -C18 carbon chains, in R, Ac or X2 possess good solubility in organic solvents which are water-immiscible and of which the boiling points lie between 40° and 150° C, preferably in aliphatic chlorinated hydrocarbons, such as tetrachloroethylene, trichloroethylene, 1,1,1-trichloroethylene or 1,1,1-trichloropropylene, can be used, optionally also mixed with one another, for the continuous dyeing of synthetic fibre materials from these organic solvents, for example in accordance with the processes of DOS (German Published Specification) No. 1,935,483 (GB 1,274,440).
For this purpose, the dyestuffs to be used according to the invention, in the solid form or in the form of solutions, are dissolved in the water-immiscible organic solvents, if appropriate with addition of known non-ionic auxiliaries. The synthetic fibre materials are impregnated with the dyestuff solutions obtained and the dyestuffs are fixed by heat treatment.

R denotes a hydrophilic radical, preferably a hydroxyalkyl radical, and
Z denotes a C2 -C4 -alkylene radical which preferably contains hydroxyl groups can be used, optionally also in the form of mixtures, for dyeing synthetic materials in accordance with the exhaustion process which is in itself known (compare, for example, DOS (German Published Specification) 2,034,264 = BE 769,803) from organic water-immiscible solvents, preferably from aliphatic chlorinated hydrocarbons, such as tetrachloroethylene, trichloroethylene, 1,1,1-trichloroethane or 1,1,1-trichloropropane, wherein these dyestuffs are sparingly soluble.
The dyeing liquors can contain small amounts, that is to say up to 1 per cent by weight, preferably up to 0.5 per cent by weight, of water, based on the weight of the organic solvents, and can optionally contain known non-ionic auxiliaries.
The dyeing according to the invention is carried out in the usual manner in closed apparatuses, the dyestuffs being employed in an amount of 0.01 to 3 per cent by weight based on the weight of the fibre materials. The synthetic fibre materials to be dyed according to the invention are above all fibre materials of polyesters, such as polyethylene terephthalate, polycyclohexanedimethylene terephthalate, heterogeneous polyesters of terephthalic acid, sulphoisophthalic acid and ethylene glycol, or copolyether-ester fibres of p-hydroxybenzoic acid, terephthalic acid and ethylene glycol, cellulose triacetate, cellulose 21/2-acetate, and synthetic polyamides obtained from hexamethylenediamine adipate, ε-caprolactam or ω-aminoundecanoic acid, and also fibre materials of polyacrylonitrile and polyurethanes. The fibre materials can be in the most diverse states of processing, for example in the form of filaments, flock, tops, yarn, piece goods, such as woven fabric or knitted fabric, or made-up goods.
The new water-insoluble dyestuffs I can also be used for the spin dyeing or bulk dyeing of polyamides, polyesters and polyolefines in accordance with processes which are in themselves known (compare DOS (German Published Specification) No. 2,037,123).

A fabric of polyethylene terephthalate fibres is impregnated at room temperature with a clear red solution which contains 10 parts of dyestuff according to Example 8a and 7 parts of nonylphenol heptaethylene glycol ether in 983 parts of tetrachloroethylene. After squeezing out to a weight increase of 60%, the fabric is dried for one minute at 80° C. The dyestuff is then fixed by heating the fabric to 190°-220° C for 45 seconds. The small proportion of non-fixed dyestuff is then eluted by brief rinsing with cold tetrachloroethylene. After drying, a clear, yellowish-tinged red dyeing is obtained, which is distinguished by its good build-up and by its good fastness properties.
EXAMPLES 9-38
If the procedure followed is analogous to that indicated in Examples 1-8, the dyestuffs listed in Table 1 are obtained by acylation from the corresponding anthraquinone derivatives; when used in accordance with the dyeing methods indicated in Examples 1-8, the dyestuffs give the shade indicated on polyester materials.

EXAMPLE 39 ##STR48##
6 parts of 1-amino-4-hydroxy-2-(2-[3-methylphenylamino]-ethoxy)-anthraquinone are suspended in 40 parts by volume of toluene. 2.3 parts of phenylisocyanate and a pinch of triethylenediamine are added to the reaction mixture and the whole is heated to the boil for 5 minutes. The dyestuff formed separates out, after prolonged standing, from the reaction mixture which has cooled. It is filtered off and washed with methanol and water. 7.3 parts of the compound indicated are obtained, melting at 161°-2° C after recrystallisation from pyridine; the compound dyes polyester materials in red shades.
EXAMPLE 40 ##STR49## a. 68 parts of benzoic acid methyl ester and 32 parts of ethanolamine are converted into 2-benzoylaminoethanol by heating to 150° C for several hours. 16.6 parts of 1-amino-2-phenoxy-4-hydroxy-anthraquinone and 5.2 parts of potassium carbonate are introduced into the crude reaction product. The mixture is warmed to 140° C and kept at this temperature for approx. 3 hours. After cooling to approx. 80° C, the dyestuff produced is caused to separate out by adding 100 parts by volume of methanol. After working up in the usual manner, 9.4 parts of the compound indicated are obtained.
b. 100 parts of a fibre yarn of polyhexamethylenediamine adipate fibres are introduced, at room temperature, into a dyebath which has been prepared from 1 part of dyestuff according to Example 40a in 1,000 parts of tetrachloroethylene. The bath is heated to 100° C over the course of 20 minutes with vigorous circulation of the liquor, and is kept at this temperature for 45 minutes. The liquor is then separated off and the fabric is rinsed with fresh tetrachloroethylene at 40° C. After separating off the rinsing liquor, the dyed goods are freed from the adhering solvent by centrifuging and drying in a stream of air. A bluish-tinged red dyeing of good fastness properties is obtained, with good dyestuff yield.
EXAMPLE 41 ##STR50## a. 172 parts of N-(3-hydroxypropyl)-benzenesulphamide, 70.5 parts of ethylene carbonate and 2 parts of finely ground potassium carbonate are heated to 200° C for 2 hours. 33.2 parts of 1-amino-2-phenoxy-4-hydroxy-anthraquinone and 8.4 parts of potassium carbonate are introduced into the reaction mixture at approx. 80°-100° C, and the mixture is stirred for approx. 2 hours at 140° C. After cooling to approx. 60° C, 200 parts by volume of methanol are added. After the customary working up, 42.3 parts of the dyestuff mixture indicated are obtained.
b. A fabric of polyester fibres (polyethylene terephthalate) is impregnated on a padder with a liquor which contains, per liter, 20 g of dyestuff of the above structure which has beforehand been brought to a finely divided state in the presence of dispersing agents. The fabric is squeezed out to a weight increase of 70% and is dried at 100° C. It is then treated with hot air at 190°-220° C for 60 seconds to fix the dyeing, rinsed, washed hot and dried. A strong red dyeing of good fastness to light, sublimation and rubbing is obtained.
EXAMPLE 42 ##STR51## a. 49.4 parts of 4-toluenesulphonic acid anilide, 17.6 parts of ethylene carbonate and 0.5 parts of potassium carbonate are heated to 200° C until the evolution of carbon dioxide has ceased. After cooling to approx. 100° C, 8 parts of 1-amino-2-phenoxy-4-hydroxy-anthraquinone and 2 parts of potassium carbonate are introduced. The mixture is then stirred for 6 hours at 140° C; after cooling, the reaction mixture is diluted with 80 parts by volume of methanol, and after working up in the usual manner 11.2 parts of the compound indicated are obtained.
The dyestuff is identical with that obtained according to Example 14 by acylation, and dyes polyester materials in fast yellowish-tinged red shades.
EXAMPLE 43 ##STR52## a. 80 parts of N,N-di-(2-hydroxyethyl)-4-tosylamide, 20 parts by volume of N-methylpyrrolidone, 2 parts of potassium hydroxide and 12 parts of 1-amino-2-phenoxy-4-hydroxy-anthraquinone are warmed to 130° C for 1/2 hour. After cooling to approx. 80° C, the dyestuff is separated out by adding 100 parts by volume of methanol, filtered off and washed with methanol and water. 16.1 parts of the compound indicated are obtained, melting at 191°-2° C after recrystallisation from chlorotoluene.
b. 100 parts of fibre yarn of poly-ε-caprolactam are introduced at room temperature into a dyebath which contains 1 part of dyestuff according to Example 43a in 1,000 parts of tetrachloroethylene. The bath is warmed to 100° C over the course of 20 minutes with vigorous circulation of the liquor and is kept at this temperature for 40 minutes. After this time, the liquor is separated off and the dyed yarn is briefly rinsed with fresh solvent, centrifuged and dried in a stream of air. A clear bluish-tinged red dyeing with good fastness properties and high dyestuff yield is obtained.
If the 1,000 parts of tetrachloroethylene are replaced by the same amount of 1,1,2-trichloroethane, pentachloroethane, 1,2-dichloropropane, 2-chlorobutane, 1,4-dichlorobutane, perfluoro-n-hexane, 1,2,2-trifluoro-trichloroethane, trifluoropentachloropropane, chlorobenzene, fluorobenzene, chlorotoluene or benzotrifluoride or if instead of poly-ε-caprolactam the polyamide of amino-undecanoic acid is used, equivalent red dyeings are obtained.
EXAMPLE 44 ##STR53## a. A mixture of 50 parts of N,N-di-(2-hydroxyethyl)-isopropylurethane, 8 parts of 1-amino-2-phenoxy-4-hydroxy-anthraquinone and 2.5 parts of potassium carbonate is heated to 140° C for approx. 4 hours. After cooling to 80° C, the mixture is diluted with 80 parts by volume of methanol and the product is filtered off cold. After filtration, and washing with methanol and water, 7.9 parts of the compound indicated are obtained.
b. 50 parts of a fabric of polyester fibres are introduced into a dyebath at room temperature, which has been prepared from 1 part of dyestuff according to Example 44a, 1.5 parts of oleic acid ethanolamide, 1.5 parts of oleyl alcohol eicosaethylene glycol ether, 6 parts of water and 500 parts of tetrachloroethylene.
The bath is heated to 120° C over the course of 10 minutes whilst vigorously circulating the liquor and is kept at this temperature for 45 minutes. After separating off the dyeing liquor, the dyed goods are rinsed with fresh solvent at 40° C and are dried in a stream of air after removing the rinsing liquor. A clear red dyeing of good fastness to light and to sublimation is obtained.
