Description
Detailed Disclosure
The present invention relates to new reactive dyestuffs containing no acid, salt-forming, water-solubilizing groups. It also relates to processes for the production of the new reactive dyestuffs which are suitable for the dyeing and printing of organic material, especially hydrophobic fibres, particularly synthetic polyamide fibre material.
It has been found that valuable reactive dyestuffs containing no acid, salt-forming, water-solubilizing groups and which, amongst others, can be applied from organic solvents, especially aprotic solvents, correspond to Formula I, ##EQU2## wherein D represents the radical of an organic dyestuff,
Q represents the bridging member --NX.sub.3 --, --O--, --S-- or --NX.sub.3 CO--, whereby X.sub.3 denotes hydrogen or a lower alkyl group,
R represents the radical of a nitrogen heterocycle containing at least one substituent which can be split off as anion and which is bound to a ring carbon atom adjacent to a tertiary nitrogen atom,
X.sub.1 represents hydrogen, an alkyl or an alkoxyalkyl group and
X.sub.2 represents an alkyl or an alkoxyalkyl group having in all at least 4 carbon atoms, whereby X.sub.1 and X.sub.2 must together contain, when X.sub.1 denotes an alkyl or an alkoxyalkyl group, at least 8 carbon atoms,
Or
X.sub.1 represents a cyclohexyl radical, unsubstituted or substituted by lower alkyl groups having preferably 1 to 4 carbon atoms, and
X.sub.2 represents an unsubstituted or substituted alkyl group having at most 18 carbon atoms, a lower alkenyl group having preferably 1 to 4 carbon atoms or a cyclohexyl radical, unsubstituted or substituted by lower alkyl groups having preferably 1 to 4 carbon atoms.
The new, valuable, water-insoluble reactive dyestuffs of Formula I are obtained by reacting a compound of Formula II,
wherein
R' represents the radical of a nitrogen heterocycle containing at least two substituents which can be split off as anion,
n represents 1 or 2 and
Hal represents chlorine, bromine or fluorine,
with an organic dyestuff of Formula III,
wherein D has the meaning given under Formula I and
Q' represents --NHX.sub.3, --OH or --SH, whereby X.sub.3 denotes hydrogen or a lower alkyl group, to give a dyestuff of Formula IV,
wherein D, Q and R' have the meaning given under Formulae I and II,
and subsequently reacting the obtained reaction product with an amine of Formula V, ##EQU3## wherein X.sub.1 and X.sub.2 have the meaning given under Formula I, and thereby selecting the components so that the obtained reactive dyestuff contains no acid, salt-forming, water-solubilizing groups.
A modification of the process according to the invention, for the production of reactive dyestuffs of Formula I, wherein Q represents the bridging member --NX.sub.3 --, --O-- or --S--, whereby X.sub.3 denotes hydrogen or a lower alkyl group, and for D, R, X.sub.1 and X.sub.2 that applies which is stated under Formula I, consists in reacting a compound of Formula II, wherein n represents one, and for Hal and R' that applies which is stated above, firstly with an amine of the above mentioned Formula V to give a compound of Formula VI, ##EQU4## wherein Hal, R, X.sub.1 and X.sub.2 have the above given meaning, and subsequently reacting the compound of Formula VI with a dyestuff of Formula III.
The radical of an organic dyestuff D can belong to any desired classes of dyestuffs. The classes of dyestuffs, however, which are primarily to be considered in this case are those which are technically easily accessible. For this reason, D represents in Formula I, e.g. the radical -- containing no acid, salt-forming, water-solubilizing groups -- of a nitro, acridone, methine, perinone, peridinecarboxylic acid imide, quinophthalone, naphthoquinonimine dyestuff, or the radical of a metal-free or heavy metal-containing phthalocyanine dyestuff and, in particular, the radical of a mono or disazo dyestuff, optionally containing heavy metal, or of an anthraquinone dyestuff.
These radicals of organic dyestuffs can contain substituents common in dyestuffs, which substituents do not dissociate anionically, e.g. halogen atoms such as fluorine, chlorine or bromine; cyano or nitro groups; hydrocarbon groups, especially lower alkyl groups such as methyl, ethyl, isopropyl, tert.butyl, amyl, and lower alkenyl groups; substituted lower alkyl or alkenyl groups, e.g. perfluoro(lower)alkyl groups such as trifluoromethyl, also hydroxyalkyl groups, e.g. hydroxy(lower)alkyl groups such as hydroxyethyl or .gamma.-hydroxypropyl; cyanoethyl or .beta.,.beta.-dicyanovinyl; ether groups, preferably lower alkoxy groups, but also aryloxy groups such as methoxy, ethoxy, butoxy, phenoxy, methylphenoxy; thioether groups, e.g. lower alkylthio or phenylthio groups such as methylthio, ethylthio, phenylthio; acyl groups such as lower alkanoyl, aroyl, lower alkylsulphonyl or arylsulphonyl groups; arylsulphonyloxy groups such as phenylsulphonyloxy groups; primary, secondary or tertiary amino groups; acylamide groups, especially lower alkanoylamide groups such as acetylamide; lower alkoxycarbonylamide groups such as ethoxycarbonylamide, or aroylamide groups such as benzoylamide groups; lower alkylsulphonylamide or arylsulphonylamide groups; carboxylic acid amide and sulphonic acid amide groups, optionally mono- or disubstituted at the nitrogen atom, especially N-lower-alkyl- or N,N-di-lower-alkylsulphonic acid amide groups.
In Formula I, Q preferably represents the bridging member --NX.sub.3 -- and X.sub.3 represents hydrogen, mehyl, ethyl or propyl.
As radical of a nitrogen heterocycle, R represents, in particular, a triazinyl or diazinyl radical, including a quinoxaline, phthalazine, quinazoline and pyridazine radical containing as substituent which can be split off as anion, e.g. lower alkylsulphonyl or dinitrophenoxy groups, particularly, however, halogen atoms such as chlorine, bromine or fluorine.
X.sub.1 in the meaning of an alkyl or alkoxyalkyl group particularly denotes such groups having from 1 to 18 carbon atoms; if both X.sub.1 and X.sub.2 represent an alkyl or alkoxyalkyl group, then each of these groups has preferably from 4 to 18, more particularly from 8 to 18 carbon atoms.
As a cyclohexyl radical, optionally substituted by lower alkyl groups, X.sub.1 and X.sub.2 represent, e.g. the 1- or 4-methylcyclohexyl radical, especially, however, the unsubstituted cyclohexyl radical. If X.sub.2 denotes an optionally substituted alkyl radical or an alkenyl radical, then this radical can be both straight-chained and branched. If the alkyl radical X.sub.2 is substituted, then suitable substituents are, in particular, hydroxyl, lower alkoxy, lower alkenyloxy and cyano groups. Examples of optionally substituted alkyl groups, denoted by X.sub.2, are: methyl, ethyl, 2-hydroxyethyl, isopropyl, sec. butyl, hexyl, octyl, dodecyl, tetradecyl, octadecyl, 2-ethylhexyl, 2-methoxyethyl, 2-ethoxyethyl, 2,2-diethoxyethyl, 2,2-dibutoxyethyl, 2-vinyloxyethyl or 2-cyanoethyl. Examples for X.sub.2 as an alkenyl group are the vinyl and allyl radical.
In preferred compounds of Formula I, X.sub.2 represents, when X.sub.1 denotes hydrogen, particularly an alkyl group having 8 to 18 carbon atoms; if X.sub.1 and X.sub.2 each represent an alkyl group, then together these preferably contain 8 to 36 carbon atoms.
In particularly preferred compounds of Formula I, however, X.sub.1 represents the unsubstituted cyclohexyl radical and X.sub.2 represents an unsubstituted alkyl radical having 1 to 4 carbon atoms, especially the methyl or ethyl radical. These preferred compounds are distinguished by their good to excellent solubility in organic solvents.
Here and in the following the expression "lower", in connection with alkyl, alkoxy and alkanoyl groups, denotes radicals having, in general, not more than 4 carbon atoms.
Suitable compound of Formula II, usable in the process according to the invention, are: triazines or diazines having at least three labile halogen atoms, e.g. cyanuric chloride, cyanuric bromide, 2,4,6-trichloropyrimidine or 2,4,6-trifluoropyrimidine, 2,4,6-tribromo- or 2,4-difluoro-6-chloro-pyrimidine.
The trihalogenpyrimidine can optionally carry in the 5-position, e.g. the following substituents: chlorine, bromine, cyano, the nitro group, carboxylic acid amide or sulphonic acid amide groups, optionally substituted at the nitrogen atom, carboxylic acid methyl ester or ethyl ester groups; acyl, e.g. benzoyl; alkenyl, e.g. allyl, chlorovinyl, chloro- or bromomethyl. Examples of such further substituted trihalogenpyrimidines are: 2,4,5,6-tetrachloropyrimidine, 5-bromo-, 5-cyano-, 5-nitro-, 5-chloromethyl-2,4,6-trichloro- or -trifluoro-pyrimidine, particularly 5-chloro-2,4,6-trifluoro-pyrimidine.
Also suitable are dihalogenpyrimidinecarboxylic acid halides, 2,3-dihalogenquinoxalinecarboxylic acid halides, 1,4-dihalogenphthalazinecarboxylic acid halides or 2,4-dihalogenquinazolinecarboxylic acid halides such as, e.g. the carboxylic acid halides of the 2,4-dibromo-, 2,4-difluoro- or, in particular, 2,4-dichloropyrimidine-5- or -6-carboxylic acid, 2,4-dichloro-6-chloromethyl-pyrimidine-5-carboxylic acid, 2,3-difluoro- or 2,3-dichloro-quinoxaline-6-carboxylic acid, 1,4-difluoro-, 1,4-dichloro- or 1,4-dibromophthalazine-6-carboxylic acid, 2,4-dichloro-quinazoline-6- or -7-carboxylic acid or 2,4-dichloropyrimidyl-5-acetic acid.
Further compounds of Formula II are: tetrachloropyridazine-, trichloro-1,2,4-triazine- and 3,6-dichloropyridazine-5-carboxylic acid chloride.
Compounds of Formula II are preferred, wherein Hal represents chlorine, n represents one and R' represents a triazinyl radical having two labile halogen atoms, especially cyanuric chloride; compounds of Formula II, wherein Hal represents chlorine or fluorine, n represents one and R' represents a diazinyl radical having at least two labile halogen atoms, especially 2,4,5,6-tetrachloropyrimidine, 5-chloro-2,4,6-trifluoro-pyrimidine or 2,4,6-trifluoropyrimidine, or compounds of Formula II, wherein Hal represents chlorine, n represents one and R' represents a diazinyl radical having at least two labile halogen atoms, especially 2,4-dichloropyrimidine-5- or -6-carboxylic acid.
Examples of amines of Formula V, usable in the process according to the invention are: isobutylamine, tert.butylamine, isohexylamine, heptylamine, tert.octylamine, nonylamine, decylamine, undecylamine, tetradecylamine, hexadecylamine, heptadecylamine, octadecylamine and dodecylamine, N-ethyl-N-octadecylamine, N-methyl-N-dodecylamine, dibutylamine, dipentylamine, dihexylamine, dioctylamine, didodecylamine, 2-methoxyethylamine, 2-ethoxyethylamine, 3-methoxy-2-methyl-propylamine, 3-(2-ethylhexoxy)-propylamine, 6-methoxyhexylamine, 3-methoxybutylamine, N,N-diethoxyethylamine, N,N-dibutoxyethylamine, N-methyl-, N-ethyl-, N-propyl-, N-tert.butyl-, N-isoamyl-, N-hexyl-, N-heptyl-, N-nonyl-, N-dodecyl, N-hexadecyl-, N-octadecyl-, N-oleyl-, N-(2-ethylhexyl)-, N-(2-hydroxyethyl)-, N-(3-hydroxypropyl)-, N-(2-methoxyethyl)-, N-(2-ethoxyethyl)-, N-(2-cyanoethyl)-, N-(2,2-diethoxyethyl)-, N-(2,2-dibutoxyethyl)-, N-(3,3-dimethoxypropyl)-, N-(2-vinyloxyethyl)-, N-vinyl- or N-allylcyclohexylamine, 1-cyclohexylamino-2-propanol, dicyclohexylamine, N-1-dimethylcyclohexylamine, N-isopropyl-1-methylcyclohexylamine and N-4-dimethylcyclohexylamine.
For the reaction of a compound of Formula II with a dyestuff of Formula III and of the obtained reaction product of Formula IV with an amine of Formula V, using the process according to the invention, as well as for the reaction of a compound of Formula II, wherein n represents one, with an amine of Formula V and of the obtained compound of Formula VI with a dyestuff of formula III, using the modified process according to the invention, the conditions have to be chosen so that a premature exchange of labile substituents does not occur either as a result of too high a pH-value of the reaction medium or in consequence of too high a temperature. The reaction is performed by methods known per se, e.g. in aqueous suspension, advantageously, however, in an organic solvent, e.g. in an organic solvent which is inert to the reactants, such as acetone, dioxane, methylethyl ketone, ethyl glycol monomethyl ether or -ethyl ether, or in a mixture of such a solvent with water. The reaction is carried out preferably at low temperatures, whereby the choice of the suitable temperature depends principally on the lability of the substituent which can be split off as anion, of the starting materials used. Advantageously, temperatures between 0.degree. and 80.degree.C are used.
In order to neutralize the hydrogen halide being released during the reaction, it is possible to add to the reaction mixture, acid-binding agents such as sodium carbonate, sodium bicarbonate, potassium phosphate, alkali salts of lower fatty acids, e.g. sodium or potassium acetate, ammonium acetate or an excess of the amine of Formula V.
If the reaction is performed in a mixture of an inert organic solvent with water, then it is advantageous to operate at a pH-value between 5 and 9, whereby the pH-value during the reaction is maintained constant by addition of one of the stated acid-binding agents.
The isolation of the dyestuffs, obtainable according to the invention, is performed in the usual manner, e.g. by filtration, concentration of the solvent and filtration, removal by distillation of the solvent and filtration or precipitation from the solvent and filtration.
The drying of the dyestuffs, obtainable according to the invention, is advantageously carried out under mild conditions, i.e. at a moderately elevated temperature and preferably in vacuo.
The reactive dyestuffs of Formula I, which can be produced according to the invention, are suitable for the dyeing and printing of organic material of very diverse kinds, by methods known per se. Suitable as organic material are, in particular, hydrophobic fibres such as fibre material made from linear high-molecular esters of aromatic polycarboxylic acids with polyfunctional alcohols, such as polyethylene glycol terephthalate, cellulose-di- and-tri-acetate fibres, polyvinyl fibres and, in particular, synthetic polyamide fibres.
A particular advantage of the reactive dyestuffs, obtainable according to the invention, is that they are excellently suitable for application from aprotic solvents alone, or from a solvent mixture consisting of aprotic solvent and a liquid, water-soluble, organic solvent which boils below 220.degree.C.
Thereby even and deeply coloured dyeings are obtained on the stated fibre material which, without an alkaline aftertreatment, have very good fastness properties, especially fastness to wet processing, rubbing and dry-cleaning.
Compared to known comparable reactive dyestuffs which contain no alkylamino or alkoxyalkylamino group on the reactive radical or which contain a lower-molecular alkylamino group to the cyclohexylamino group on said radical, the reactive dyestuffs of Formula I, obtainable according to the invention, are characterized by an appreciably better solubility in an aprotic solvent alone, or in a solvent mixture, e.g. in a solvent mixture consisting of lower aliphatic halogenated hydrocarbons, such as tri- or tetrachloroethylene ("perchloroethylene"), and a liquid, water-soluble or water-miscible organic solvent boiling below 220.degree.C, such as lower alkanols or N,N-dialkylamides of lower monocarboxylic acids. Thereby deeply coloured and fast dyeings are obtained.
The following Examples illustrate the invention. In the Examples, the temperatures are given in degrees Centrigrade.

To this solution are added dropwise within 30 minutes at 0.degree.-5.degree., 18.4 g of cyanuric chloride dissolved in 100 ml of acetone. An aqueous sodium carbonate solution is simultaneously added dropwise in such a manner that the reaction remains always neutral. After completion of the condensation, the temperature is raised to 30.degree. with the simultaneous addition of, in all, 20.2 g of hexylamine, at a pH-value of 7 - 8. After completion of the reaction, the dyestuff of the above formula is completely precipitated by the yellow suspension being poured on to water. The dyestuff is then filtered and washed with water. After being dried in vacuo, it is in the form of a yellow powder.

Example 120
8 g of the dyestuff, produced according to Example 60, are dissolved in 1000 g of trichloroethylene. With this solution a fabric made from polyamide-6.6 is impregnated at room temperature, the fabric squeezed out to give a dye liquor absorption of ca. 75%, relative to the dry weight of the material, and the impregnated material then dried at 80.degree. in an air stream. The dyestuff is afterwards thermofixed during 5 minutes at 170.degree..
Without aftertreatment, an even and well developed yellow dyeing is obtained having good fastness to wet processing and to rubbing.
If, instead of 1000 g of trichloroethylene, the same amount of chlorobenzene is used, then likewise is obtained a deeply coloured, well developed, yellow and fast dyeing.
