For this purpose, dyestuffs which in the form of their free acids have the formula ##STR3## can be reacted either first with trifluorotriazine and then with an amine of the formula ##STR4## or with a difluorotriazine derivative of the formula ##STR5##When compounds (II) in which Ar represents sulphoarylene with the sulpho group in the o-position relative to the --NH--R.sub.4 group are used, these are appropriately reacted first with trifluorotriazine and then with (III).In the formulae (II), (III) and (IV), R.sub.1 to R.sub.6 and also Ar, a, b and c have the meaning indicated above.Examples of suitable compounds of the formula (III) are: ammonia, methylamine, dimethylamine, ethylamine, diethylamine, propylamine, butylamine, dibutylamine, isobutylamine, amylamine, .beta.-hydroxyethylamine, .gamma.-hydroxypropylamine, methyl-.beta.-hydroxyethylamine, methoxyethylamine, ethoxyethylamine, N-.beta.-hydroxyethyl-N-ethylamine, aminoacetic acid, aminopropionic acid, .beta.-amino-ethanesulphonic acid, cyclohexylamine, 3-methylcyclohexylamine, benzylamine, aniline, 2-naphthylamine, m-toluidine, p-toluidine, 3,4-dimethylaniline, 3,5-dimethylaniline, 3-ethylaniline, 3-chloroaniline, 4-chloroaniline, 3,4-dichloroaniline, 3,5-dichloroaniline, 3-methyl-4-chloroaniline, 4-methyl-3-chloroaniline, 3-methoxyaniline, 4-methoxyaniline, 3-ethoxyaniline, 4-ethoxyaniline, 3-nitroaniline, 4-nitroaniline, 3-aminobenzoic acid amide, N-methylaniline, N-ethylaniline, 3-amino-acetanilide, 4-methylamino--acetanilide, piperidine, morpholine, o-toluidine, 2-methoxy-aniline, 2-ethoxyaniline, 2,4-dimethylaniline, 2,5-dimethylaniline and 2-chloroaniline.These reactions are acylation reactions and can be carried out in an aqueous, aqueous-organic or organic, preferably weakly acid to weakly alkaline medium at temperatures of -10.degree. to +80.degree. C. and preferably of -5.degree. to +10.degree. C.The phthalocyanine compounds of the formula (II) which are used in the process according to the invention can be prepared by reacting a phthalocyaninesulphonic acid chloride--preferably in the form of an aqueous suspension of the formula ##STR6## wherein Pc has the meaning indicated above,m designates the numbers 0, 1 or 2 andn designates the numbers 2, 3 or 4 andthe sum m plus n is not greater than 4,with diamines or monoacylated diamines of the formula ##STR7## and optionally with a compound of the formula ##STR8## in which formulae R.sub.1, R.sub.2, R.sub.3, R.sub.4 and Ar have the meaning indicated above,and, if monoacylated diamines of the formula (VIb) are used, subjecting the terminal acylamino group in the resulting phthalocyanine compounds to acid or alkaline saponification. In this reaction unconverted sulphonic acid chloride groups are converted to sulphonic acid groups.Phthalocyaninesulphonyl chlorides and phthalocyaninesulphonyl chloride-sulphonic acids of the formula (V) can be obtained by treating the corresponding phthalocyanine or the phthalocyaninesulphonic acid with chlorosulphonic acid and, optionally, an acid halide, such as thionyl chloride, phosphorus pentachloride, phosphorus oxychloride or phosphorus trichloride, as described in British Pat. Nos. 708,543, 784,834 and 785,629 and U.S. Pat. No. 2,219,330.According to the invention it is possible to use phthalocyanine dyestuffs which are single compounds, that is to say those in which the letters a, b and c characterise the numbers 0, 1, 2 or 3. In addition, however, it is also possible to use mixtures of these dyestuffs. Sometimes mixtures of this type have particular advantages in respect of solubility and substantivity. In such mixtures the average value of the numbers varies.Mixtures, according to the invention, of this type are prepared, for example, from two or more end dyestuffs of the formula (I), each of which is a single compound, or, particularly advantageously by using a mixture of the starting components. The latter frequently is necessarily formed since the phthalocyaninesulphonyl chloridesulphonic acids (V) are frequently obtained industrially in the form of mixtures, in respect of the degree of sulphonation and the ratio of sulphonyl chloride groups and sulphonic acid groups contained therein.The following may be mentioned as examples of suitable diamines of the formula (VIa) and suitable monoacylated diamines of the formula (VIb): 1,4-diaminobenzenesulphonic acid, 1,3-diaminobenzene-4-sulphonic acid, 2-sulpho-4-methyl-1,3-phenylenediamine, N,N'-bis-(3-sulpho-4-aminophenyl)-urea, 2-sulpho-4-methyl-1,5-phenylenediamine, 2-methyl-5-sulpho-1,3-phenylenediamine, 4,4'-diamino-(1,1'-biphenyl)-3-sulphonic acid, 1-sulpho-3,4-naphthenediamine, 1-sulpho-4,5-naphthylenediamine, 5-sulpho-1,2-naphthylenediamine, 5-sulpho-2,4-naphthylenediamine, 2-sulpho-5-acetylamino-8-aminonaphthalene, 2-amino-5-acetylamino-benzoic acid, 2-amino-4-acetylamino-benzoic acid, 3-amino-5-acetylaminobenzoic acid, 2-sulpho-4-aminophenyl-oxamic acid, N,N'-bis-(4-amino-3-carboxyphenyl)-urea, 6-amino-2-acetylaminotoluene-4-sulphonic acid, 4-amino-4'-acetylaminodiphenylamine-2-sulphonic acid, 2-amino-5-[(3-aminobenzoyl)-amino]-benzenesulphonic acid, 4-amino-2-acetylamino-benzoic acid and 4,6-diaminotoluene-3-sulphonic acid.The new dyestuffs are extremely valuable products which are suitable for very diverse applications.As water-soluble compounds they are of interest for dyeing and printing textile materials which contain hydroxyl groups and textile materials which contain nitrogen, especially textile materials made of natural and regenerated cellulose, and also materials made of wool, silk and synthetic polyamide and polyurethane fibres. They are particularly suitable as reactive dyestuffs for dyeing and printing cellulose materials by the techniques recently disclosed for this purpose. The resulting fastness properties, especially the wet-fastness properties, are excellent.For dyeing and printing cellulose, the dyestuffs are preferably employed in an aqueous solution, to which substances having an alkaline reaction, such as an alkali metal hydroxide or alkali metal carbonate, or compounds which are converted to substances having an alkaline reaction, such as an alkali metal bicarbonate or Cl.sub.3 C--COONa, can be added. Further auxiliaries can be added to the solution but these should not react in an undesirable manner with the dyestuffs. Such additives are, for example, surface-active substances, such as alkyl sulphates, or substances which prevent the migration of the dyestuff, or dyeing auxiliaries, such as urea or inert thickeners, such as oil/water emulsions, tragacanth, starch, alginate or methylcellulose.The solutions or pastes prepared in this way are applied to the material to be dyed, for example by padding in a padder (short liquor) or by printing, and then heated for some time at elevated temperature, preferably 40.degree. to 150.degree. C. Heating can be carried out in a hot flue, in a steaming apparatus, on heated rollers or by introducing the material into heated concentrated salt baths and these operations can be carried out either on their own or successively in any order.When a padding or dyeing liquor without alkali is used, passage of the dry goods through a solution which has an alkaline reaction and to which sodium chloride or Glauber's salt is added follows dyeing. The addition of a salt reduces the migration of the dyestuff from the fibre.The material to be dyed can also be pre-treated with one of the abovementioned acid-binding agents, then treated with the solution or paste of the dyestuff and finally fixed at elevated temperature, as indicated.For dyeing from a long liquor, the material is introduced into an aqueous solution of the dyestuff (liquor ratio 1:5 to 1:40) at room temperature and dyed for 40 to 90 minutes, raising the temperature to 95.degree. C. if necessary and optionally adding, in portions, a salt, for example sodium sulphate and then alkali, for example sodium phosphates, sodium carbonate, NaOH or KOH.The chemical reaction between the dyestuff and the fibre than takes place. After chemical fixing has been carried out, the dyed material is rinsed hot and finally soaped, by which means non-fixed residues of the dyestuff are removed. Dyeings with excellent fastness properties, especially wet-fastness properties and fastness to light, are obtained.In the so-called cold pad-batch method, subsequent heating of the padded fabric can be saved by storing the fabric at room temperature for some time, for example 2 to 20 hours. In this process, a stronger alkali is employed than in the case of the dyeing method from a long liquor, which has been described above.For printing materials containing hydroxyl groups, a printing paste consisting of the dyestuff solution, a thickener, such as sodium alginate, and a compound which has an alkaline reaction or splits off alkali on heating, such as sodium carbonate, sodium phosphate, potassium carbonate, potassium acetate or sodium bicarbonate and potassium bicarbonate, is used and the printed material is rinsed and soaped.Textile materials containing amide groups, such as wool, silk and synthetic polyamide and polyurethane fibres, are generally dyed in the acid to neutral range by the dyeing methods customary for this purpose.The dyeings obtainable with the new dyestuffs are in general distinguished by good to very good fastness properties, especially by outstanding wet-fastness properties.The present invention also relates to difluorotriazinyl compounds, which, in the form of the free acid, have the formula ##STR9## wherein Pc, R.sub.1 -R.sub.4 and a, b and c have the meaning indicated above.These compounds are obtained as defined above, by reacting trifluorotriazine with (II).
