Transiently water-soluble disperse mono-azo dyes containing a diamino-methylene-carbacyl group

The invention provides transiently water-soluble disperse dyes, a process for their manufacture and a method of using them for dyeing and printing hydrophobic synthetic organic material, especially polyester material.
It is generally known to dye hydrophobic synthetic organic material, especially polyester material, with disperse dyes as described, for example, in the Colour Index. These dyes are coloured, organic compounds which do not contain water-solubilising groups, such as sulphonic acid or ammonium groups, and which are only imperceptibly soluble in water and exhaust onto the material from a molecular disperse solution. To this end, the disperse dyes must be very finely ground before the actual dyeing procedure and stabilised in the aqueous dyebath by adding large amounts of dispersants. During the dyeing, the dye is not in solution but in dispersion. In actual practice this often gives rise to considerable difficulties, for these dyestuff dispersions are frequently unstable: the dye crystallises out and this in turn results in unlevel dyeings. Particularly in high temperature dyeing, insufficient stability of the dispersions becomes apparent through filtration phenomena in thick material, as on cheeses and in beam dyeing. In addition, the dispersants in large-scale dyeing machinery can lead to foaming and, since they are largely poisonous, result in severe effluent pollution. Problems also arise in the dyeing of blended fabrics, since water-soluble dyes are often poorly conpatible with the dispersants of the disperse dyes.
It is the object of the present invention to provide dyes which make it possible to avoid these difficulties by dyeing hydrophobic, synthetic organic material in a slightly acid, neutral or alkaline solution of transiently water-soluble disperse dyes that contain a group which can be removed under the dyeing conditions and which carries at least one water-solubilising group.
The invention therefore provides dyes of the formula ##STR2## wherein F is a dye of the disperse class, especially an anthraquinone or an azo dye, n is 1 or 2, and W is the radical of a diammonium or aminoammonium compound which is linked to the methylenecarbonyloxy radical through one of the two ammonium groups.
The new dyes are obtained either by
a. reacting the dye of the formula ##STR3## wherein F and n having the meanings previously assigned to them and Z is a labile acyl group of a strong acid, for example sulphuric acid or especially one of the hydrohalic acids, with n moles of a diamine which contains at least one alkylatable nitrogen atom, and, if appropriate, subsequently quaternising the non-quaternised nitrogen atoms with alkylating agents, or
b. coupling the diazonium compound of a diazo component with a coupling component, at least one of said components containing a radical of the formula
--O--CO--CH.sub.2 --W
wherein W has the meaning already assigned to it, or
c. condensing two components the combination of which yields the dye and which altogether contain at least one group of the formula
--O--CO--CH.sub.2 --W.
the new dyes are brought into contact with the fibres in a slightly acid, neutral or slightly basic solution under the customary dyeing conditions for synthetic fibres, for example at elevated temperature of about 80.degree. to 130.degree. C and a pH of c. 4 to 8, especially 5 to 7 and above all of about 5.
A reverse formation of the original disperse dye thereby takes place by hydrolysis at the carbacyl group and the dye then exhausts onto the polyester material. Under optimal conditions, the rate of hydrolysis and exhaustion of the water-soluble disperse dye are in such a ratio that the free disperse dye is unable to accumulate, i.e. it exhausts immediately onto the material. The dyebath remains clear and the dyeing can be carried out without dispersants means that the effluent is less heavily polluted and a contribution to the effluent problem is thereby made.
Preferably the new dyes have the formula ##STR4##
wherein F has the meaning already assigned to it and R.sub.1 is an unsubstituted or a substituted alkyl or aralkyl radical, R.sub.2 is an unsubstituted or a substituted alkyl or aralkyl radical, R.sub.3 is a hydrogen atom or an unsubstituted or a substituted alkyl or arylkyl radical or together with R.sub.1 or R.sub.4 is a lower alkylene radical, preferably an athylene radical, R.sub.4 is a hydrogen atom or an unsubstituted or a substituted alkyl or aralkyl radical or together with R.sub.2 is a lower alkylene radical, preferably an ethylene radical, R is an unsubstituted or a substituted alkyl or aralkyl radical, but is particularly a hydrogen atom, and L is an unsubstituted or a substituted alkylene chain or an alkylene chain which can be interrupted by heteroatoms, such as oxygen, sulphur or nitrogen atoms, or is a direct bond.
Dyes having an especially interesting utility are those of the formula ##STR5## wherein F, L, R.sub.1, R.sub.2, R.sub.3 and R.sub.4 have the meanings previously assigned to them.
Suitable radicals W are in particular the groups of the formulae ##STR6## wherein the positive charges are neutralised by a corresponding number of those anions which are customary in quaternised dyes.

They are, for example, metalliferous monoazo or polyazo dyes, including also formazane dyes, and anthraquinone or acridone dyes, nitro, methine, styryl, naphthoperinone and quinophthalone dyes. Metal-free azo and anthraquinone dyes are preferred.

As a rule, the completely alkylated diamines which do not, however, contain any quaternary nitrogen atoms, are reacted in organic media such as methyl ethyl ketone, acetone, acetonitrile and the like with haloacetic esters of disperse dyes, i.e. with compounds of the formula F (O--CO--CH.sub.2 -halogen).sub.n.
The salt-like reaction products are substantially insoluble in the above media and can be isolated by filtration.
Normally one chloracetic ester dye molecule reacts with one molecule of amine. A surplus of amine is generally used in order to prevent a double reaction of two molecules of dye with one molecule of diamine.
If at least one of the amino substituents R, R.sub.3 and R.sub.4 is a hydrogen atom, then the dyes can also be in the nonprotonised form, depending on the pH. But under dyeing conditions of below about pH 6 they are transformed into the positively charged, protonised form.
Dyes in which one of the substituents R, R.sub.3 and R.sub.4 is hydrogen are expediently obtained by reaction of the above mentioned monoquaternary dyes with alkylating agents, such as dimethyl sulphate, methyl iodide, benzyl chloride and the like.

It is preferred to use those amines in which the nitrogen atoms are separated only by two carbon atoms, i.e. amines which yield, for example, the following groups W: ##STR37##
The azo dyes according to the invention can also be obtained by coupling a diazonium compound of an amine with a coupling component, with at least one of the components having to contain a group of the formula
-alkylene--O--COCH.sub.2 W.
suitable diazo components which contain the groups of the formula
--OCOCH.sub.2 W
have e.g. the formula ##STR38## wherein X has the meaning assigned to it in formula VI and the ring G can be substituted by lower alkyl, alkoxy, chlorine and bromine, lower alkylsulphonyl, nitro or cyano. Particular examples are the anilines of the formulae ##STR39##
Examples of aromatic diazo compounds with the radical OCOCH.sub.2 W are those of the naphthalene and especially of the benzene class. As substituents of the benzene ring there may be mentioned primarily halogen atoms, especially chlorine and bromine, nitro, cyano, thiocyano, trifluoromethyl, alkyl, alkoxy, aryloxy, alkylmercapto, arylmercapto, carboxy amide, acyl and acylamino radicals as well as phenylazo groups, wherein the phenyl nucleus can be substituted by chlorine, nitro, alkyl and alkoxy.
By "alkyl" and "alkoxy" are meant in this connection low molecular radicals of 1 to 5 carbon atoms, preferably methyl and methoxy. "Acyl" denotes radicals of aliphatic and aromatic carboxylic, sulphonic and sulphonic acids, especially benzoyl (which may be substituted at the benzene nucleus), benzenesulphonyl, benzylsulphonyl radicals, as well as radicals of alkylsulphonic acids which contain at most 4 carbon atoms, and aliphatic carboxylic acids. The sulphonic and carboxylic acid amide groups can carry one or two alkyl groups which can also be linked to a ring.
Such aminobenzenes can, for example, be substituted according to the formula ##STR40## wherein R.sub.1 " is hydrogen, bromine, thiocyano, alkoxysulphonyl, hydroxy, alkylmercapro, arylmercapto, acylamino, or preferably chlorine, nitro, cyano, acyl, sulphonamide, carboxy amide, alkoxy or aryloxy, R.sub.2 " is bromine, carboxy amide, alkoxycarbonyl or preferably hydrogen, R.sub.3 " is hydrogen, bromine, chlorine, thiocyano, aryloxy or acylamino or preferably nitro, cyano, sulphonamide, carboxy amide, trifluoromethyl or phenylazo, wherein the phenyl nucleus can be substituted by alkyl, alkoxy, nitro and chlorine, R.sub.4 " is bromine, nitro, cyano, thiocyano, acyl, carboxy amide, alkoxy, aryloxy or acylamino, chlorine, sulphonamide, trifluoromethyl or alkyl, or is preferably hydrogen, R.sub.5 " is in particularly hydrogen, chlorine or bromine, nitro, cyano, thiocyano, acyl, trifluoromethyl or alkyl.
Acyl, alkyl and alkoxy have the same meanings in this connection as stated previously hereinbefore.
Examples of such acyl radicals are: benzoyl, 4-chlorobenzoyl, 4-methylbenzoyl, benzenesulphonyl, acetyl, propionyl, chloroacetyl or methylsulphonyl radicals.
It is further to be borne in mind that 2 strong electron acceptors, i.e. electrophilic substituents like nitro or acyl groups, may never be in ortho-position to each other. But the opposite is possible with of halogen atoms, cyano and alkoxycarbonyl groups. Hydroxy, alkoxy and alkyl groups or halogen atoms are preferably in orthoposition to strong electron acceptors.

-alkylene-OCOCH.sub.2 W
and the other radicals R" have the meaning previously assigned to them.
Suitable coupling components which contain one or two groups of the formula
alkylene-OCOCH.sub.2 W
can be obtained by reaction of a coupling component with the group of the formula -alkylene-OCOCH.sub.2 C and the amine of the formula HW. Examples of such starting materials are, for example, those of the formulae ##STR42## wherein c, d, R.sub.1 ', R.sub.2 ' and R.sub.1 have the meanings previously assigned to them.
Coupling components with the group -O-CO-CH.sub.2 -W have, for example, the formulae ##STR43##
Such coupling components can be obtained, for example, by acylating corresponding coupling components which contain a free hydroxy group with .alpha.-bromo- or .alpha.-chloroacetic chloride and then reacting the acylation products with amines and, if appropriate, quaternising them.

In addition to the naphthols, there may be mentioned as coupling components of the naphthalene class 1- or 2-naphthylamine as well as 2-phenylaminonaphthalene, 1-dimethylaminonaphthalene or 2-ethylaminonaphthalene. Examples of coupling components of the heterocyclic class are the indoles, e.g. 2-methylindole, 2,5-dimethylindole, 2,4-dimethyl-7-methoxyindole, 2-phenyl- or 2-methyl-5-ethoxyindole, N,.beta.-cyanoethyl-2-methyl-indole, 2-methyl-5-or 2-methyl-6-chloroindole, 1,2-dimethylindole, 1-methyl-2-phenylindole, 2-methyl-5-nitroindole, 2-methyl-5-cyanoindole, 2-methyl-7-chloroindole, 2-methyl-5-fluoro- or 2-methyl-5 -bromoindole, 2-methyl-5,7-dichloroindole, or 2-phenylindole, 1-cyanoethyl-2,6-dimethylindole, pyridines, e.g. 3-cyano-2,6-dihydroxy-4-methylpyridine, and also pyrazoles, for example 1-phenyl-3-methyl-5-amino-pyrazole or 3-methylpyrazolone-5 or 1-phenyl-3-methyl-pyrazolone-5, 1,3-dimethyl-pyrazolone-5, 1-butyl-3-methylpyrazolone-5, 1-oxyethyl-3-methyl-pyrazolone-5, 1-cyanoethyl-3-methylpyrazolone-5, 1-(o-chlorophenyl)-3-methyl-pyrazolone-5, 3-carbomethoxy-pyrazolone-5, quinolines, e.g. 8-hydroxyquinoline, 1-methyl-4-hydroxyquinoline, N-ethyl-3-oxy-7-methyl- or N,.beta.-cyanoethyl-1,2,3,4-tetrahydroquinoline, or pyrimidines, e.g. barbituric acid, as well as 1,3-indandione, 1,8-naphthindadione, dimedone, acetoacetic anilide, m-hydroxy-N,N-diethylaniline, 3-hydroxy-4'-methyldiphenylamine, hydroquinone-monoethyl ether, acetyl acetone, 5-hydroxy-benzthiazole and 1,2-diphenyl-pyrazolin-3,5-dione.
The coupling can also be effected in known manner, for example in acid medium, if appropriate in the presence of sodium acetate or similar buffer substances which influence the rate of coupling, or catalysts, for example dimethyl formamide, pyridine and salts thereof.
Anthraquinone dyes according to the invention can be obtained by acylating water-insoluble anthraquinone dyes which contain external aliphatic hydroxy groups with .alpha.-bromoacetic or .alpha.-chloroacetic chloride and subsequently reacting them with the amines HW.
The novel dyes are excellently suited for printing and especially for dyeing regenerated man-made or preferably synthetic man-made materials, especially textile fibres.
Suitable substrates are, for example, materials like polyacrylonitrile and copolymers of acrylonitrile and other vinyl compounds, e.g. acrylic esters, acrylic amides, vinyl pyridine, vinyl chloride or vinylidene chloride, copolymers of dicyanoethylene and vinyl acetate, as well as of acrylonitrile block copolymers, polyurethanes, synthetic polyamides, e.g. poly(hexamethylene adipic acid amide) or polyamide 66, poly( -caprolactam) or polyamide 6, poly(hexamethylenesebacic amide) or polyamide 610, and poly(11-aminoundecanoic acid) or polyamide 11, preferably cellulose triacetate and cellulose 2 1/2-acetate and above all polyesters, e.g. those from terephthalic acid and ethylene glycol or 1,4-dimethylol cyclohexane, and copolymers of terephthalic and isophthalic acid with ethylene glycol and, if appropriate, 1,4-dimethylol cyclohexane.
These materials can be in the most widely differing processed forms, for example spun yarns, knitted fabrics, woven fabrics, yarns or fibers.
These materials are dyed with the dyes according to the invention under such conditions that the group of the formula
F--O--CO--CH.sub.2 --W
is split as follows
F--OH+HOOC--CH.sub.2 --W
so as to form a water-insoluble disperse dye which exhausts as such onto the material.
This is accomplished by dyeing the material at elevated temperature, for example at 80.degree. to 130.degree. C, if appropriate under pressure, in a slightly acid, neutral or alkaline bath at a pH of c. 3 to 10, preferably 4 to 7. Buffer systems which contain, for example, phosphates or carboxylates, may be added to this dyebath. The novel dyes have a particularly good temporary solubility in aqueous dyebaths.
The process has the advantage of being extraordinarily easy to operate. Both the dyeing and printing procedure can be carried out by the conventional methods and, besides the new dyestuff derivatives, no disproportionately large amounts of assistants and also no special machinery is required.
Compared with conventional disperse dyeing, this process has a number of decisive advantages which have already been mentioned at the outset, viz. that the dyes do not have to be in dispersion and therefore the complicated grinding problems involved in the use of disperse dyes do not arise. Also no mainly poisonous, effluant polluting dispersants are required, so that consequently the troublesome foaming problems which occur in large-scale apparatus do not arise.

The following Examples illustrate the invention, the parts and percentages being by weight unless otherwise stated and the relationship between parts by weight and parts by volume being the same as that between the gram and the milliliter.
EXAMPLE 1
4.5 parts of the dye of the formula ##STR45## are dissolved in 25 parts by volume of acetone at 50.degree. C and the solution is treated with 1.36 parts of 4-N,N-dimethylpiperazine. After the mixture has been heated for 3 hours to 50.degree. C, the quaternary dye is filtered off, washed with acetone, and dried to yield 4.2 parts of a red powder of the formula ##STR46## which has very good solubility in cold water.
When this dye is applied to polyester in the exhaustion process over the course of 1 hour at 130.degree. C and in the presence of a phthalate buffer at a pH between 4 and 7, there are obtained level dyeings of a red shade with very good fastness properties. The addition of an assistant to the dyebath is not necessary.
EXAMPLE 2
The chloroacetic ester dye of Example 1 is reacted under the same conditions and in the same molar ratios with the amine of the formula ##STR47## to yield the dye of the formula ##STR48## in crystalline form.
A clear solution of this dye in a glacial acetic acid/acetate buffer which is adjusted to a pH of 4.5 is applied to polyester fabric in a HT circulating machine at a dyestuff:liquor ratio of 1:12. Dyeing is performed for 50 minutes at 130.degree. C and the dye liquor is then drawn off while hot. A faultlessly dyed polyester fabric of good fastness properties is obtained. The use of dyeing assistants, for example dispersants, is unnecessary.
EXAMPLE 3
52.6 parts of the dye of the formula ##STR49## are stirred into 400 parts by volume of methyl ethyl ketone and 20 parts by volume of anhydrous pyridine. At room temperature 20 parts by volume of chloroacetyl chloride are added slowly dropwise and stirring is performed until no more starting product can be detected in thin layer chromatography. Then 35 parts by volume of tetramethylpropylenediamine are added and quaternisation is effected at 60.degree. C. After 8 hours, the dye of the following formula has formed in virtually quantitative yield. ##STR50## It is filtered off and dried after being washed once with acetone at 60.degree. C. Yield: 100 parts. The ruby coloured dye is of good purity and has very good solubility in cold water. Polyester fabric is dyed with this dye for 60 minutes at 130.degree. C in a HT dyeing machine in the presence of a phthalate buffer with a pH of 5. Level, bluish red dyeings of very good fastness properties are obtained. The addition of any assistants is superfluous.
EXAMPLE 4
58 parts of the disperse dye of the formula ##STR51## are dissolved in a mixture of 500 parts by volume of methyl ethyl ketone and 13 parts by volume of pyridine. Then 13 parts by volume of chloroacetyl chloride are added slowly dropwise. Stirring is then continued for 1 hour after the exothermic reaction has subsided. Then 40 parts by volume of N,N,N',N-tetramethylethylenediamine are added and the mixture is diluted with 100 parts by volume of methyl ethyl ketone and stirring is continued for 3 hours at 60.degree. C. The batch is then cooled to room temperature and the precipitated dye of the formula ##STR52## is filtered off, washed with acetone and dried at 60.degree.-70.degree. C in a high vacuum. Tightly packed polyester fabric is dyed with water-soluble dye in a pressure dyeing apparatus at 130.degree. C and a pH of 5. A very level, orange red dyeing of outstanding fastness properties is obtained. Neither dispersants nor any other assistants need be used. The dyes listed in the following Tables 1-8, which yield the indicated shades on polyester fabric, are obtained in analogous fashion from the corresponding chloroacetic esters.
EXAMPLE 5
10.95 parts of the dye of Example 2 in Table 3 are suspended in 66 parts of chlorobenzene at 45.degree. to 50.degree. C. This suspension is then reacted for 3 hours at the same temperature with 2.17 parts of dimethyl sulphate, in the process of which the second nitrogen atom in the water-solubilising radical W is also quaternised. Filtration yields 13.1 parts of the dye of the following constitution ##STR53## 1.5 g of the dye are dissolved in 2 liters of water of 50.degree. C and a pH of 5 is established by addition of 80% acetic acid. Then 100 g of a polyester fabric are put into this dyebath, which is heated within 30 minutes to 130.degree. C in a sealed apparatus. Dyeing is performed for 60 minutes at this temperature. The fabric is subsequently rinsed and subjected to an aftertreatment for 20 minutes at 70.degree. C in a liquor which contains 2 g of hydrosulphite and 3 ml of sodium hydroxide solution (36.degree. Bd) per liter of water and then dried. A level, brilliant, pink dyeing of good fastness properties is obtained. It was not necessary to use any assistants (e.g. dispersants).
