Description

The invention relates to uniformly dyed water-swellable cellulosic fibers which are fast to washing, dry-cleaning, sublimation and light and have been produced by contacting water-swellable cellulose fibers sequentially or concomitantly with water, ethylene glycol or a derivative thereof and, while the fibers are still swollen, an essentially water-insoluble dye of the formula ##STR3## in which D is the radical of a diazo component;
R.sup.1 and R.sup.2 are optionally substituted alkyl and one of them may also be cyclohexyl, phenyl, methoxyphenyl or ethoxyphenyl and
X is hydrogen, chloro, methyl or acylamino, the molecule containing in the radicals R.sup.1, R.sup.2 and

Y is oxygen, sulfur or ##STR4## Ar is phenyl or phenyl bearing chloro, bromo, methyl, methoxy, ethoxy, C.sub.1 to C.sub.4 alkoxycarbonyl or cyano as a substituent.

The dyes of the formulae (I), (Ia) and (Ib) in which D, D.sup.1 and D.sup.2 are derived from amines of the benzoisothiazole series and the heterocyclic substituted benzene series are new.
The dyes of the formula (I) may from their constitution be regarded as substantially insoluble disperse dyes whose application for example to cotton is not possible as a rule. U.S. Pat. No. 3,706,525 discloses however a process which enables them to be printed on cellulose and cellulosic textile material. Statements made therein regarding the process conditions hold good also for dyeing with the dyes of formula I. Other methods are disclosed in U.S. patent application Ser. No. 691,496 according to which the fibers according to this invention may be obtained. Printing processes are preferred. As well as cellulose fibers it is possible to dye and print mixtures of cellulose fibers and synthetic fibers, particularly mixtures of cotton and polyester.
The fibers according to the invention have excellent fastness properties, the wet fastness and in some cases also light fastness being particularly worthy of mention. In the case of prints there is no staining of any white ground, for example during washing.
For dyeing and printing, the dyes of formula (I) are advantageously used in the form of dye formulations which, in addition to the dyes of formula (I), contain dispersants, water retention agents, water and if so desired other conventional constituents in dye formulations, for example disinfectants or antifoam agents.
Suitable dispersants are cation-active compounds, but preferably nonionic and particularly anion-active compounds, i.e., the dispersing agents usually employed for disperse dyes.
Specific examples are lignin sulfonates, sulfomethylation products of phenol, condensation products of phenolsulfonic acids, phenol, formaldehyde and urea, condensation products of .beta.-sulfonaphthalene and formaldehyde and also polyaddition products of propylene oxide and ethylene glycol, propylene glycol or ethylene diamine.
Glycols and glycol ethers such as ethylene glycol, propylene glycol, diethylene glycol or ethylene glycol monomethyl ether are particularly suitable as water retention agents.
In the following Examples, which illustrate the invention, parts and percentages are by weight unless otherwise specified.

EXAMPLE 1
69 parts of 4-amino-5-bromo-7-nitro-1,2-benzoisothiazole is dissolved at 10.degree. to 15.degree. C in 500 parts of 96% sulfuric acid. 150 parts of a mixture of acetic acid and propionic acid in the ratio 17:3 is added at 0.degree. to 5.degree. C and diazotization is carried out by dripping in 75 parts of nitrosylsulfuric acid (11.5% of N.sub.2 O.sub.3). The whole is stirred for another 3 to 4 hours at 0.degree. to 5.degree. C and the diazo solution is then allowed to flow into a suspension of 125 parts of N,N-bis-(phenoxyacetyloxyethyl)-m-toluidine in 500 parts of acetic acid, 200 parts of concentrated hydrochloric acid, 5 parts of sulfamic acid, 1000 parts of ice and 1000 parts of water. The whole is then diluted with about 2000 parts of ice-water and stirred overnight. The crystalline precipitate is suction filtered, washed with water until neutral and dried at 60.degree. C at subatmospheric pressure. The dye obtained as an olive-black powder is printed as an aqueous dispersion or dissolved in a polyethylene glycol onto polyester cloth, cotton or union fabric of both types of fiber and fixed with hot air or superheated steam. Deeply colored violet prints having good fastness properties are obtained.
Commercial formulations of this and following dyes may be obtained for example as follows:
30 parts of dye,
6 parts of dispersant,
10 parts of water retention agent,
1 part of disinfectant and about
53 parts of water are ground in an agitator mill to a particle size of about 0.5 micron. A dispersion of the dye is thus obtained which is stable in storage.
EXAMPLE 2
55 parts of 2-(2-methyl-1,3,4-oxadiazolyl)-4-nitroaniline is introduced at 0.degree. C to 5.degree. C into a mixture of 500 parts of 85% sulfuric acid and 81 parts of nitrosylsulfuric acid (11.5% of N.sub.2 O.sub.3). After stirring for 4 hours at 0.degree. to 5.degree. C the diazo solution is poured into a solution of 77 parts of N,N-diethyl-N'-phenoxyacetyl-1,3-phenylenediamine in 500 parts of glacial acetic acid, 5 parts of sulfamic acid, 1000 parts of ice and 1000 parts of water. Coupling is completed by the addition of 400 parts of sodium acetate (crystalline) in 2000 parts of water. The crystalline black-violet product is filtered off, washed with water until free from salt and neutral and dried at subatmospheric pressure at 50.degree. C. The dye dissolves in dimethylformamide and polyethylene glycol with a reddish violet color. When union fabric of polyester and cotton or cloth of the pure fibers is printed with solutions or aqueous dispersions of the dye and then treated with superheated steam or hot air clear reddish violet prints having good fastness properties are obtained.
EXAMPLE 3
73 parts of 4-diphenylphosphinylaniline is dissolved in 800 parts of 85% sulfuric acid at 40.degree. to 50.degree. C. The whole is cooled to 0.degree. to 5.degree. C, diazotized by the addition of 81 parts of nitrosylsulfuric acid (11.5% of N.sub.2 O.sub.3) and stirred for 3 to 4 hours at 0.degree. to 5.degree. C. After coupling with 77 parts of N,N-diethyl-N'-phenoxyacetyl-1,3-phenylenediamine in the manner described in Example 2 a red powder is obtained which dissolves in dimethylformamide and polyethylene glycol with a reddish orange color. Clear and deep orange hues having very good fastness properties are obtained on cloth of polyester, cotton or blends of the two.
EXAMPLE 4
66.5 parts of 2',3-dichloro-4-aminoazobenzene and 10 parts of an oxyethylated sperm oil alcohol containing about 23 ethylene oxide radicals are stirred overnight with 500 parts of water and 110 parts of 36% hydrochloric acid. 250 parts of ice is added and diazotization is carried out by adding 55 parts by volume of a 23% sodium nitrite solution. After the whole has been stirred for 2 hours at 5.degree. to 10.degree. C the excess nitrous acid is removed with sulfamic acid. The diazo compound is coupled with 77 parts of N,N-diethyl-N'-phenoxyacetyl-1,3-phenylenediamine in the manner described in Example 2. The reddish brown powder obtained which dissolved in dimethylformamide and polyethylene glycol with a reddish violet color gives ruby prints having good fastness properties on polyester, cotton or polyester/cotton union fabric.

EXAMPLE 98
60.5 parts of the dye of the formula: ##STR27## is stirred in 500 parts of N,N-dimethylformamide with 28 parts of cuprous cyanide (70%) for 8 hours at 65.degree. C. 400 parts of methanol is added at ambient temperature and the dye is then filtered off, washed with methanol, 10% aqueous ammonia solution and water and dried at 50.degree. C at subatmospheric pressure. The dye of the formula: ##STR28## is obtained as a bluish black powder. When the dye is applied to cotton cloth, polyester cloth or cotton/polyester union fabric analogously to Examples 5 to 10, bluish violet prints or dyeings are obtained having good fastness properties.
The same dye is obtained by the reaction of a dye of the formula: ##STR29## with an agent forming cuprous cyanide or by diazotization of 2,6-dicyano-4-nitroaniline and coupling with N,N-dimethyl-N'-phenoxyacetyl-1,3-phenylenediamine as described in Example 2.
The following dyes having similar tinctorial properties are prepared in the same manner:
