II o H R represents a straight or branched-chain alkylene radical, e.g. methylene, ethylene, propylene, butylene, 2,2- dimethyl-propyl, isobutyl and the like; cycloalkylene e.g. cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl and the like; or alkylene-oxyalkylene, e.g. C H OC H C H OC H and the 1ike;

(1) Reaction of an imido alcohol with 1-amino-2- aryloxy-4-hydroxyanthraquinone,
(2) Reaction of an imido alcohol with 1-amino-4 hydroxyanthraquinone-Z-sulfonic acid or salts thereof, and
(3) Reaction of an imide with 1-amino-2 haloa1koxy-4- hydroxyanthraquinone.
The first method is preferred as will be shown in the following examples:
EXAMPLES Example 1.Preparation of N-2- hydroxyethylsuccinirnide An amount of g. of succinic anhydride was added portionwise to 61 g. of 2-aminoethanol. The temperature rose to about 124 C. during the addition. The material was then heated for 1 hr. at C. and distilled under vacuum to yield 125.9 g. of product, M.P. 5458 C.
Example 2.Preparation 0t N-3- hydroxypropylsuccinimide The procedure of Example 1 was repeated, substituting an equimolar quantity of 3-aminopropanol-1 for Z-aminoethanol. Vacuum distillation of the reaction mixture yielded 111.8 g. of the product.
Example 3.-Preparation of N-3-(2-hydroxyethoxy) propylsuccinimide The procedure of Example 1 was repeated, substituting an equimolar quantity of 3-aminopropoxyethanol for 2- aminoethanol. Vacuum distillation of the reaction mixture yielded 129.1 g. of product.
Example 4.-Preparation of N-2- hydroxyethylphthalimide The procedure of Example 1 was repeated, substituting an equimolar quantity of phthalic anhydride for succinic anhydride. The reaction mixture was diluted with 500 ml. methanol. An amount of 133.0 g. of product was obtained, M.P. 125126 C. Evaporation of methanol permitted recovery of an additional 37.6 g. of product, M.P. 123-124 C.
Example An amount of 5.0 g. of N-2-hydroxyethylsuccinimide, 0.9 g. of l-amino-4-hydroxy-2-phenoxyanthraquinone, and 0.25 g. of potassium hydroxide was heated at l35140 C. for a period of 3 hr., with a slow stream of nitrogen above the surface to aid in the removal of phenol. The material was neutralized with acetic acid and diluted with alcohol so that it could be drowned in water and filtered. The precipitate was dissolved in acetone and filtered, and the acetone solution was drowned in hexane to precipitate the product. Further purification can be accomplished by recrystallizing from hot Z-methoxyethanol and diluting the solution to obtain the dye. The product is 1-amino-4- hydroxy-2-(2 succinimide)ethoxyanthraquinone, which dyes polyesters in a bright, lightfast shade of red, with good resistance to sublimation. It also dyes cellulose acetate in a bright, light-fast shade, only slightly less bluish than the polyester.
The above compound may also be prepared by using solvents in addition to a large excess of hydroxyethylsuccinimide such as dimethyl sulfoxide or N-methyl pyrrolidone or a mixture of pyridine and dimethyl formamide. The product had the structure:
The 3-hydroxypropylsuccinimide in Example 6 was replaced by N-hydroxyethoxypropylsuccinimide. The product is 1-amino-4-hyrlroxy-2-[2-(3-succinimidopropoxy)- ethoxy]anthraquinone, which dyes polyesters and cellulose acetate in bright, light-fast shades like those obtained from the compound of Examples 5 and 6. The product had the structure:

After 4.5 hr. at 7580 C., the solution was poured into 60 ml. of Water, with 10 ml. methanol being used to rinse the reactor flask. 10 ml. 5% HCl were used to destroy the alkalinity. The precipitate was filtered out and recrystallized from hot Z-methoxyethauol solution. The product was l-amino 4 hydroxy-2-[2-(2-succinimidoethoxy) ethoxy]anthraquinone. The red shade on polyesters and cellulose acetate exhibited excellent light-fastness, and the dyeings on polyesters showed no sublimation to heat at 350 F. for one minute.
The same compound was obtained by reacting N-2-(2- hydroxyethoxy) ethylsuccinimide with 1-amino-4-hydroxy- Z-phenoxyanthraquinone. The product had the structure:

Example 9 When the succinimide in Example 8 was replaced by phthalimide, and the anthraquinone intermediate in EX- ample 8 was replaced by l-amino-Z-(2-chloro)ethoxy-4- hydroxyanthraquinone, the product was 1-amino-4- hydroxy-2-(2-phthalimido)ethoxyanthraquinone. The same compound was obtained by reacting 1-amino-4-hydroxy' 2-phenoxy-anthraquinone with N-Z-hydroxyethyl phtha limide. The product had the structure:
0 NH, 00 l OC2H4-N Example 10 l-amino 4 hydroxy-2-(2-succinimido)ethoxyanthraquinone was prepared from the corresponding anthraquinone sulfonic acid by the following method: 4.0 g. of potassium hydroxide, 15 ml. of N-methylpyrrolidine, 2.0 g. of 1-amino-4-hydroxyanthraquinone-2-sulfonic acid, sodium salt and 5.0 g. of N-2-hydroxyethylsuccinimide were reacted at l20-125 C. for 8 hr. A lower yield of product was obtained by this method than by the method phenoxyanthraquinone, 0.50 g. of potassium hydroxide, and 0.2 ml. of pyridine was reacted at 162-170 C. for 6 hr. The material was diluted carefully with methanol while being cooled. The precipitate was filtered out and recrystallized from 2-methoxyethanol. The product was 1 amino 4 hydroxy-2-[(Z-phthalimidoethoxy)ethoxy] anthraquinone. It showed dyeing characteristics almost identical with that of the corresponding succinimide compound. The product had the structure:
NH: 00 l In accordance with the methods of preparation set forth in Examples through 11, additional anthraquinone dyestuffs were prepared corresponding to the general formula CO R0R N Z wherein R and Z are set forth in the following table:

Patents 2,880,050, 2,757,064, 2,782,187 and 2,043,827. The following example illustrates a method by which the anthraquinone compounds of the invention can be used to dye polyester textile materials.
0.1 g. of the dye is dissolved in the dye pot by warming in 5 cc. of ethylene glycol monomethyl ether. A 2% sodium-N-methyl-N-oleyl taurate and 0.5% sodium lignin sulfonate aqueous solution is added, with stirring, until a fine emulsion is obtained. Water is then slowly added to a total volume of 200 cc. 3 cc. of Dacronyx (a chlorinated benzene emulsion) are added and 10 grams of a textile fabric made of Kodel polyester fibers are entered. The fabric is worked 10 minutes Without heat and then for 10 minutes at C. The dye bath is then brought to the boil and held at the boil for one hour. Following this, the fabric is rinsed in warm water, then scoured in aqueous 0.20% soap, 0.2% soda ash solution. After scouring, the fabric is rinsed With Water and dried. Accordingly, since the anthraquinone compounds of the invention are water-insoluble, they can be applied from aqueous dispersions in the manner of the so-called dispersed dyes. However, coloration can also be effected, for example, by incorporating the anthraquinone compounds into the spinning dope and spinning the fiber as usual. The anthraquinone compounds of our invention have varying utility as dyes. The degree of utility varies, for example, depending upon the material being dyed and the formula of the anthraquinone compound. Thus, for example, all the dyes will not have the same degree of utility for the same material.
Polymeric linear polyester materials of the terephthalate type are illustrative of the linear aromatic polyester textile materials that can be dyed with the new anthraquinone compounds of our invention. The terephthalate fibers sold under the trademarks Kodel, Dacron, and Terylene, for example, in the form of filaments, yarn and fabric, for example, are illustrative of the polyester textile materials that can be dyed. Kodel polyester fibers are more particularly described in US. Patent 2,901,446. Dacron and Terylene polyester fibers are described, for example, US. Patent 2,465,319. The polymeric linear polyester materials disclosed in Us. Patents 2,945,010, 2,957,745 and 2,989,363 for example, can be dyed. The linear aromatic polyester materials specifically named have a melting point of at least 200 C.
Nylon, in fiber, yarn and fabric form, is representative of polyamides which can be dyed with the compounds.
The invention has been described in considerable detail with particular reference to certain preferred embodiments thereof, but it will be understood that variations and modifications can be effected within the spirit and scope of the invention as described hereinabove, and as defined in the appended claims.
