Azo dyes from sulfonated 3-sulfonated 3-amino-2,1-benzisothiazoles with 1,2,3,4-tetrahydroquinoline or 2,3-dihydro-1,4-benzoxazine couplers

Abstract

Disclosed are azo dyes in which the diazo component is a diazotized 3-amino-2,1-benzisothiazole compound bearing one or two sulfo groups, and the coupler is either a 1,2,3,4-tetrahydroquinoline or a 2,3-dihydro-1,4-benzoxazine compound. These dyes exhibit excellent dyeing and fastness properties on polyamide fibers and also impart color to cellulose acetate fibers and wool. The dyes correspond to the general formula: ##STR1## wherein R.sup.5 is 0-3 substituents independently selected from halogen, cyano, alkyl, alkoxy, sulfo, and the like; M is H.sup.+, Na.sup.+, K.sup.+ or the like; and C is the coupler which may be substituted with groups known to the art.

Description

This invention relates to azo dyes in which the diazo component is from a 3-amino-2,1-benzisothiazole compound bearing one or two sulfo groups, and the coupler is a 1,2,3,4-tetrahydroquinoline or 2,3-dihydro-1,4-benzoxazine compound. These dyes, in general, exhibit excellent dyeing and fastness properties on polyamide fibers, imparting neutral to greenish blue shades thereto, and also impart color to cellulose acetate fibers and wool, and are particularly valuable in not flaring red under artificial light while retaining good lightfastness.

The dyes correspond to the general formula: ##STR2## wherein R.sup.5 is 0-3 substituents independently selected from halogen, cyano, alkyl, alkoxy, alkylthio, alkylsulfonyl, sulfamoyl, alkylsulfamoyl, alkanoyloxy, carbamoyl, alkylcarbamoyl, alkoxycarbonyl, acylamido, and SO.sub.3 M; M is selected from H.sup.+, NH.sub.4.sup.+, Na.sup.+, K.sup.+, and the colorless cations of salts of primary, secondary, and tertiary aliphatic and aryl amines; C is a coupler having the formula ##STR3## wherein R is selected from hydrogen, alkyl, aryl, and cycloalkyl; R.sup.1, R.sup.2, and R.sup.3 are each selected from hydrogen and alkyl; R.sup.4 is 0-2 substituents and R.sup.6 is 0 or 1 substituent selected from alkyl, alkoxy, halogen, acylamido, alkylthio, and aryloxy; and wherein the alkyl moieties of R, R.sup.4, R.sup.5 and R.sup.6, e.g. of the alkoxy groups, are unsubstituted or substituted with 1-3 substituents independently selected from halogen, CN, OH, alkoxy, aryloxy, alkoxyalkoxy, alkanoyl, alkanoyloxy, carbamoyl, alkylcarbamoyl, sulfamoyl, alkylsulfamoyl, aryl, alkoxycarbonyl, alkoxyalkanoyloxy, and cycloalkyl.

Typical of the amines which may be used to form the "M" salts are triethylamine, tri(2-hydroxyethyl)amine, di(2-hydroxyethyl)amine, and N,N-dimethylaniline.

Preferred of the present dyes are those wherein: R.sup.5 is 0-3 substituents independently selected from Cl, Br, alkyl, alkoxy, and --SO.sub.3 M; R is alkyl, or alkyl substituted with 1-3 substituents independently selected from hydroxy, Cl, Br, alkoxy, carbamoyl, alkanoyloxy, alkoxycarbonyl, cyano, phenyl, and sulfamoyl; R.sup.1, R.sup.2 and R.sup.3 are each independently selected from H and methyl; and R.sup.4 is 0-2 substituents independently selected from alkyl, alkoxy, alkylthio, phenyl, and acylamido. The most preferred of the above dyes are those wherein R.sup.5 is H or one of said preferred substituents in the 4 or 5 position, and R.sup.4 is H or one of said preferred substituents in the seven position.

The alkyl and alkylene moieties within the definitions of the above R-R.sup.6 groups contain from 1-6 carbons and are straight or branched chain, and the aryl groups have 6-10 ring carbons.

The dyes of this invention impart blue to greenish blue shades to fibers, particularly polyamides, and are especially useful for dyeing polyamide (nylon) carpets, giving improvements over such dyes as shown, for example, in German Offenlegungsschrift Nos. 2,716,033 and 2,805,304, in one or more properties such as fastness to light, ozone, oxides of nitrogen, perspiration, washing, sublimation, and crocking, leveling, migration, transfer, exhaustion, build, barre coverage, pH stability, and insensitivity to pesticides such as those containing organic phosphate esters.

This invention will be exemplified further by the following examples, although it will be understood that these examples are included merely for the purpose of illustration and are not intended to limit the scope of the invention. The diazo and coupler components of the present dyes can be prepared by procedures well-known in the art.

EXAMPLE 1

A solution of 10.0 g. of 3-amino-2,1-benzisothiazole in 100 g. of concentrated H.sub.2 SO.sub.4 was heated at 50.degree.-55.degree. C. for one-half hour, then cooled and added to 500 ml. of cold acetone. The product was removed by filtration and then reprecipitated from bicarbonate solution by addition of sufficient acetic acid to give a pH of 4.75-4.80. 8.5 Grams of purified 3-amino-2,1-benzisothiazole-7-sulfonic acid product was obtained.

A 0.025 mol. portion (5.76 g.) of the above sulfonic acid product was dissolved in 50 ml. of aqueous KOH (1.2 g. KOH), 50 g. of ice added, and then 6.9 g. of NaNO.sub.2 added, followed by dropwise addition of 10 ml. of 37% HCl. The temperature was then maintained at 0.degree. to 5.degree. C. for one hour and the excess nitrite then destroyed with sulfamic acid.

A 0.025 mol. portion of the coupler 1-(2-hydroxyethyl)-2,2,4,7-tetramethyl-1,2,3,4-tetrahydroquinoline (5.84 g.) was dissolved in 75 ml. of 6% HCl, the solution chilled in an ice bath and the above diazonium solution added thereto. Sodium acetate was added after 30 min. to obtain a pH of 4-5 and the product was removed by filtration after an additional one hour in the ice bath. Dilute NaCl solution (10%) was used to wash the precipitate. The dried dye weighed 10.85 g. and its formula is that of the first dye of Table I.

EXAMPLE 2

Fifteen g. of 3-amino-5-chloro-2,1-benzisothiazole were added to 90 g. of 20% oleum, with external cooling to prevent the temperature from exceeding 60.degree. C. After one-half hour at 60.degree. C. the solution was cooled and added to 520 ml. of cold acetone. A 7.9 g. portion of pure sulfonic acid product was removed by filtration of the chilled acetone mixture, and an additional 5.2 g. of product, only slightly less pure, were recovered by evaporating a major part of the acetone and drowning the remaining solution in water.

The 3-amino-5-chloro-2,1-benzisothiazole-7-sulfonic acid was diazotized in a nitrosyl sulfuric acid solution prepared from 2.16 g. of NaNO.sub.2 in 15 ml. of concentrated H.sub.2 SO.sub.4 below 70.degree. C. At below 25.degree. C., 15 ml. of 1:5 acid (propionic:acetic) were added to the above solution followed by 0.03 mol (7.94 g.) of the amine at 0.degree. C., followed by 15 ml. more of 1:5 acid. The temperature was held at 0.degree. to -2.degree. C. for two hours before treatment with sulfamic acid to destroy excess nitrite.

A 0.03 mol. portion of the coupler 1-ethyl-2,2,4,7-tetramethyl-1,2,3,4-tetrahydroquinoline (6.52 g.) was dissolved in 150 ml. of 15% H.sub.2 SO.sub.4, the solution chilled in an ice bath and the above diazonium solution added thereto. Sodium hydroxide solution (25%) and ice were then added until a pH of 4.15 was reached. After one hour, the dye was removed by filtration, extracted with water at 65.degree.-70.degree. C., and NaCl added with cooling to get the final precipitate which was washed with 2% NaCl solution and dried to constant weight. A yield of 9.09 g. of dye product was obtained. The following tables give additional examples of the present dyes which are prepared as above.
