Phthalocyanine Reactive Dyestuffs

The present invention relates to phthalocyanine reactive dyestuffs which in the form of the free acid corresponding to the formula I ##STR2## wherein Pc=the radical of a phthalocyanine,

A=an alkylene radical with at least 2 C atoms,

Z=an alkylene radical,

Y=a reactive group,

Q=a group which confers solubility in water,

a=0-2,

b=0-2,

c=1-4 and

a+b+c.ltoreq.4.

The phthalocyanine radical Pc can be metal-free but preferably contains metal. Suitable metals are cobalt, nickel and copper.

In dyestuffs of the formula (I), each sulphonic acid group or sulphonamide group is bonded, in the 3- or 4-position, to a different benzene ring of the phthalocyanine.

The alkylene radicals represented by A are preferably alkylene radicals with 2 to 6 C atoms, such as, for example, trimethylene, propylene, tetramethylene, cyclohexylene and especially ethylene radicals.

The alkylene radicals represented by Z are preferably alkylene radicals with 1-6 C atoms, such as, for example, methylene, ethylene, propylene, isopropylene and butylene radicals.

The group Q is, for example, a carboxyl, sulpho, sulphato or disulphimide group. The disulphimide group has the formula II

In this formula, R.sub.1 denotes a lower alkyl radical, that is to say an alkyl radical with 1-6 C atoms, or an aryl radical which may optionally be substituted further. Examples of R.sub.1 are the methyl, n-butyl, phenyl, tolyl, p-chlorophenyl or naphthyl radical.

The alkylene radicals can be straight-chain or branched.

Reactive groups Y are to be understood as groups which possess one or more reactive groups or removable substituents which, on applying the dyestuffs to cellulose materials in the presence of acid-binding agents and, if necessary, with exposure to heat, can react with the hydroxyl groups of the cellulose, or, on application to high molecular weight polyamide fibres, such as wool, can react with the NH group of these fibres, to form covalent bonds. A large number of such fibre-reactive groupings are known from the literature.

Reactive groups which are suitable according to the invention and which contain at least one removable substituent bonded to a heterocyclic radical or to an aliphatic radical, are, inter alia, those which contain at least one reactive substituent bonded to a 5-membered or 6-membered heterocyclic ring, such as to a monazine, diazine or triazine ring, for example pyridine, pyrimidine, pyridazine, pyrazine, thiazine, oxazine or asymmetrical or symmetrical triazine ring, or to a ring system of this type which possesses one or more fused aromatic rings, such as a quinoline, phthalazine, cinnoline, quinazoline, quinoxaline, acridine, phenazine and phenanthridine ring system; the 5-membered or 6-membered heterocyclic rings which possess at least one reactive substituent are, accordingly, preferably those which contain one or more nitrogen atoms and can contain fused 5-membered or preferably 6-membered carbocyclic rings.

Compounds of the formula I which carry a monohalogeno-sym.-triazine radical as the fibre-reactive radical Y and are represented by the formula X ##STR9## can also be prepared by replacing a radical X in dyestuffs of the formula XI ##STR10## by the radical E in the known manner, by condensation with a compound H--E (XII).

In formulae X and XI,

Pc, A, Z, Q, a, b and c have the stated meaning,

wherein

R.sub.2 denotes an optionally substituted alkyl, aryl or heteroaryl radical,

In this method of preparation, the following mercapto, hydroxyl and amino compounds of the formula XII are suitable reactants:

Aliphatic or aromatic mercapto or hydroxyl compounds, such as thioalcohols, thioglycollic acid, thiourea, thiophenols, mercaptobenzthiazoles, methyl, ethyl and isopropyl alcohol, glycollic acid, phenol, chlorophenols or nitrophenols, phenolcarboxylic acids and phenylsulphonic acids, naphthols and naphtholsulphonic acids, but especially ammonia and compounds which contain amino groups which can by acylated, such as hydroxylamine, hydrazine, phenylhydrazine, phenylhydrazinesulphonic acids, carbamic acid and its derivatives, semi- and thiosemi-carbazides and -carbazones, methylamine, ethylamine, isopropylamine, methoxyethylamine, methoxypropylamine, dimethylamine, diethylamine, methylphenylamine, ethylphenylamine, chloroethylamine, ethanolamines, propanolamines, benzylamine, cyclohexylamine, morpholine, piperidine, piperazine, aminocarbonic acid esters, ethyl aminoacetate, aminoethanesulphonic acid and N-methylaminoethanesulphonic acid, but above all aromatic amines, such as aniline, N-methylaniline, toluidines, xylidines, chloroanilines, p- and m-aminoacetanilide, nitroanilines, aminophenols, nitrotoluidines, phenylenediamines, toluylenediamines, anisidine, phenetidine, diphenylamine, naphthylamine, aminonaphthols, diaminonaphthalenes and, in particular, anilines containing acid groups, such as sulphanilic acid, metanilic acid, orthanilic acid, anilinedisulphonic acid and aminobenzoic acid, nphthylamine-monosulphonic acid, -disulphonic acid and -trisulphonic acid, aminobenzoic acids, such as 1-hydroxy-5-aminobenzoic acid, and aminonaphthol-mono-, -di- and -tri-sulphonic acids.

The invention further relates to compounds of the formula VIII ##STR11## wherein Pc, A, Z, Q, a, b and c have the stated meaning.

Compounds of the formula VIII are obtained by alkylating the compounds of the formula XIII ##STR12## wherein Pc, A, a, b and c have the stated meaning, with c mols of alkylating agents of the formula XIV

wherein

Z and Q have the stated meaning and

L represents a group which can be split off as an anion.

The alkylation of the compunds of the formula XIII can be carried out in an aqueous, aqueous-organic or organic solvent, at temperatures between 0.degree. and 140.degree. C., preferably between 20.degree. and 100.degree. C., and in this reaction it is advantageous to neutralise or buffer the liberated acid by adding alkali, such as, for example, sodium bicarbonate, sodium carbonate, sodium hydroxide solution or sodium acetate. Suitable organic solvents are, above all, acetone, chlorohydrocarbons, such as ethylene chloride or chlorobenzene, or aprotic polar solvents, such as dimethylformamide.

Examples of alkylating agents of the formula XIV are chloroacetic acid, bromoacetic acid, 2-chloropropionic acid, 2-bromopropionic acid, 3-chloropropionic acid, 3-bromopropionic acid, 2-chlorobutyric acid, 2-bromobutyric acid, 3-chlorobutyric acid, 3-bromobutyric acid, 4-chlorobutyric acid, 4-bromobutyric acid, 2-methyl-3-chloropropionic acid, 2-methyl-3-bromopropionic acid, 2-chloroethanesulphonic acid, 2-bromoethanesulphonic acid, 4-chlorobutanesulphonic acid and 4-bromobutanesulphonic acid, as well as halogenoalkyldisulphimides of the formulae XV and XVI

wherein R.sub.1 represents methyl, n-butyl, phenyl, tolyl or p-chlorophenyl.

Compounds of the formula VIII, with Q=OSO.sub.3 H, are obtained by alkylating XIII with alkylene oxides, such as ethylene oxide, and then converting the products to the sulphuric acid half-esters.

Phthalocyanine compounds of the formula XIII can themselves be produced by reacting a phthalocyanine-sulphochloride of the formula XVII ##STR13## wherein Pc has the stated meaning and

m represents a number from 0 to 3,

n represents a number from 1 to 4 and

the sum of m and n is at most 4,

in an aqueous medium, with a diamine of the formula XVIII ##STR14## wherein A has the abovementioned meaning.

Examples of diamines of the formula XVIII are ethylenediamine, propylenediamine, 1,4-diaminobutane, 1,6-diaminohexane and 1,4-diaminocyclohexane.

The phthalocyanine compounds of the formula XIII can furthermore be produced by reacting phthalocyanine-sulphochlorides of the formula XVII, in a manner which is in itself known, with mono-N-acetylated diamines of the formula XIX ##STR15## wherein A has the same meaning as in formula XVIII and subsequently removing the acetyl radical by hydrolysis under acid or alkaline conditions.

If the phthalocyanine-sulphonyl chloride of the formula XVII contains fewer sulphonic acid groups than are desired for the compound of the formula I, those sulphochloride groups which have not reacted with the diamine are hydrolysed to sulphonic acid groups.

Phthalocyaninesulphonic acid chlorides of the formula XVII can be obtained by treating the corresponding phthalocyanine or phthalocyaninesulphonic acid with chlorosulphonic acid, if necessary in the presence of carbon tetrachloride or of an acid halide, such as thionyl chloride, sulphuryl chloride, phosphorus pentachloride, phosphorus oxychloride and phosphorus trichloride, as described in British patent specifications Nos. 708,543, 784,834 and 785,629 and in U.S. Pat. No. 2,219,330.

The dyestuffs according to the invention can be single substances, that is to say the letters a, b and c represent integers. Preferably, however, the process of preparation results in mixtures which are characterized by non-integral numbers for a, b and c. These numbers are mean values. At times, such mixtures show particular advantages in respect of solubility and substantivity. In such mixtures, the numbers in the mean value vary.

Such mixtures according to the invention are prepared, for example, from two or more final dyestuffs of the formula I, each of which are single substances, or, particularly advantageously, by using a mixture of the starting components. The latter is often formed necessarily, since the phthalocyaninesulphonic acid chloride-sulphonic acids show differences in respect of the degree of sulphonation and in respect of their ratio of sulphonic acid chloride to sulphonic acid.

The new dyestuffs of the formula I are suitable for dyeing and printing materials containing hydroxyl groups or containing amide groups, such as textile fibres, yarns and fabrics consisting of wool, silk, synthetic polyamide and polyurethane fibres, and for the wash-fast dyeing and printing of natural or regenerated cellulose, the treatment of cellulose materials advantageously being carried out in the presence of acid-binding agents and, if necessary, with exposure to heat, in accordance with the processes which have been disclosed for reactive dyes.

The stated formulae of the dyestuffs are those of the corresponding free acids. The dyestuffs were in general isolated, and employed for dyeing, in the form of the alkali metal salts, especially the Na salts.
