A, stands for a divalent bridge member of the aliphatic, aromatic, aliphatic-aromatic cycloaliphatic or heterocyclic series which may be interrupted by hetero atoms or groups of hetero atoms, A; for a divalent bridge member of the aliphatic, aromatic, aliphatic-aromatic, cycloaliphatic or heterocyclic series which may be interrupted by hetero atoms or groups of hetero atoms, each of the substituents R R R and R stands for hydrogen or a lower alkyl radical which may be substituted, both the substituents X and Y stand for hydrogen or a lower alkyl or hydroxyalkyl radical, and where the dye molecule as a whole bears a number of water-solubilizing groups required to impart solubility in water.
The process for the production of the phthalocyanine compounds of Formula (I), consists in reacting 1 mole of a cyanuric halide in either order with 1 mole of a compound of formula Examples of suitable water-solubilizing groups are sulphonic acid, carboxylic acid, methylsulphonyl and ethylsulphonyl groups and the sulphonamide group, which latter group may be monosubstituted, preferably by lower hydrocarbon radicals. The phthalocyanine compounds of Formula (I) bear at least four or five sulphonic acid groups to render them sufficiently soluble in water for practical application. At the other extreme it is hardly possible to introduce more than 14 sulphonic acid groups into the dye molecule. It is preferable for the phthalocyanine compounds of Formula (I) to contain six to 12 sulphonic acid groups, some of which may be replaced by carboxylic acid, alkylsulphonyl or optionally monosubstituted sulphonamide groups. lt is to be noted, however, that the water-solubilizing action of the carboxylic acid group and the optionally monosubstituted sulphonamide group is heavily pH-dependent. In the cold only the salts of the alkali metals of these groups have effective solubilizing action; the acid forms are considerably less effective.
Other groups exercising slight to very slight water-solubilizing action, such as hydroxyl, acetylamino, carbomethoxyamino, carbethoxyamino and disubstituted sulphonamide groups, are of only minor importance.
The most suitable cyanuric halides are cyanuric bromide and cyanuric chloride, of which the latter is preferred.
The compound of Formula ([1) can be prepared by reacting a chloride of phthalocyanine triand/or tetra-sulphonie acid with a compound of the formula where Z represents a nitro group,
a group or a group Ilia 1?: NH Nacyl:
or of the group by saponification into Llu' group The compound of Formula (lll) can be produced in an analogous manner.
The hthalocyanine triand/or tetra-sulphonic acid chlorides are derived from metal-free phthalocyanine or from metal-containing phthalocyanines, preferably nickel or copper phthalocyanines. They bear the sulphonic acid chloride groups in the 3-positions of the benzene nuclei if they are produced by direct sulphochlorination, or in the 4positions if they are obtained from the analogous sulphonic acids.
The substituents R R R and R represent preferably, hydrogen atoms, lower (i.e. with one to about five carbon atoms) alkyl, hydroxyalkyl, alkoxyalkyl or halogenoalkyl radicals, or benzyl radicals. If the radical A or A is aromatic or cycloaliphatic, it is advisable to choose hydrogen atoms or aliphatic radicals as R,, R R or R The bridge member A, m A; may bl an aliphatic radlcal, such as an urmuatic radical, such as ail a cycloaliphatic radical, such as or an aliphatic-aromatic radical, such as and 5 ,x soar sour The acyl substitutent in the radical I --Nacyl SOQH .l 50311 is preferably acetyl, propionyl, methoxycarbonyl or ethox- It; may be interrupted by hetero atoms or groups of ycarbonyl'The radlcal hetero atoms, e.g. X
--N -oHr-oH2-0 cm- HF. -CHQCH2 -C \Y w is preferably the amino group or a methylamino, O- 7' dimethylamino, ethylamino, diethylamino, 2-hydroxyethylamino, di-(Z-hydroxyethyl)-amino, 2- or 3- hydrox ypropylamino or 3-hydroxybutylamino group.
Very good properties are shown by phthalocyanine dyes of 0st: .O thefonnula -Nw where P and PC' stand for the radicals of copperor 40 nickel-containing phthalocyanines; X X Y and Y inde- Hosb 303B pendently of each other, for hydrogen or lower alkyl or hydroxyalkyl radicals; Hal for bromine or preferably chlorine; and m, n, p and r for whole numbers from 1 to 3, where n m -C -N=N p r= 4; in particular dyes in which at least one of the radicals PC" and PC' stands for a nickel-containing phthalocyanine radical and at least one of the bridge members A and 3 A bears an azo group. H0 S The cyanuric halide can be conveniently reacted with a compound of Formula (II) or (III) in aqueous medium at 5 N TN I to 20C, or preferably at 0-5C, and at a weakly acid to neutral reaction, e.g., in the pH region of 3 to 7 or preferably, CH3 4 to 6. The cyanuric halide is employed as it is or in solution in H 0 an organic solvent, such as acetone.
- N For the second reaction it is best to apply temperatures of C V \77 30 to 70C or preferably, 4050C and to work in the pH region of 5 to 9 or preferably, 6 to 8.
The phthalocyanine compounds of Formula (I) thus formed can be precipitated by the addition of salt, filtered ofl with Q suction, washed and dried. Depending on the compounds C selected for the reaction, reactive dyes for cellulosic fibers are obtained having certain specific properties. Thus, when A, and/or A are small radicals, such as alkylene or phenylene radicals, and the number of sulphonic acid groups is limited,
H0 for example, to six, dyes with good power of build-up suitable ,OAJHZCH for exhaustion dyeing are obtained, whilst a greater number of such groups, for example eight, results in dyes of lower sub- S 5 SIEISH stantlvity which hence are easier to wash off and are specially CH3 suitable for printing. Components in which the sulphonic acid groups are in the 4-position of the phthalocyanine molecule give less substantive dyes than those bearing the SO;,H
N groups in the 3-position.
2 The properties of the dyes of Formula (I) are above the ex- N=N pected average of the corresponding dyes, which contain only one phthalocyanine radical.
For example, the dye of the formula (SOgH)3 (S BH)3 NIL N I =1 The good properties shown by the dyes of this invention are surprising, since with reactive dyes an enlargement of the molecule generally has an adverse effect.
The new phthalocyanine compounds of Formula (I) which contain as A and/or A small radicals such as alkylene or phenylene radicals and eight or more water-solubilizing groups, preferably sulphonic acid and/or optionally substituted sulphonamide groups, have good solubility in water, good stability in printing pastes and padding liquors, good compatibility with salts and hard water, good reactivity with cotton, linen and other naturalcellulosic fibers, and with regenerated cellulosic fibers such as viscose filament yarn,
viscose staple fibers and cuprammonium rayon.
Phthalocyanine compounds of Formula (1) containing as A and/or A larger radicals with substantive properties, e.g.,
H 0 3 L I ""N bOzH SOaH U H3 are suitable for exhaustion dyeing even if they contain eight or more, e.g., up to 12, water-solubilizing groups. These dyes are unaffected by the ions of heavy metals, such as copper, iron and chromium ions, and they reserve acetate, triacetate, polyester, polyacrylonitrile, polyvinyl chloride, polyvinyl acetate and polyalkylene fibers. As their substantivity is only moderate, the unfixed proportion of dye can be washed off with ease.
The copper-containing dyes of Formula (I) in which the bridge members A, and A, stand for optionally substituted aliphatic and/or phenylene radicals have a pleasing turquoiseblue shade. If the compounds of Formulae (11) and (111) are chosen so that at least one of the bridge members A and A contains an azo group and at least one of the radicals (PC) and (PC) stands for a nickelcontaining phthalocyanine radical, attractive green dyes are obtained which are notable for their good light fastness in dyeings on cellulosic fibers.
Goods of cellulosic fiber dyed, padded or printed with the dyes of this invention are aftertreated in alkaline medium, if necessary at high temperature, and then soaped, rinsed and dried. The dyeings have good fastness to light in the dry and wet states and to wet treatments including water, washing, acid and alkaline perspiration, rubbing, alkalis, and acetic acid cross dyeing. They are fast to dry cleaning and stable to crease resistant finishing and to acid and alkaline hydrolytic influences.
In the following examples the parts and percentages are by weight and the temperatures are given in degrees centigrades.
EXAMPLE 1 A solution of 18.4 parts of cyanuric chloride in 70 parts of acetone is prepared at 3035 and added with good stirring to 300 parts of ice-water to form a suspension. A neutral solution of 106.6 parts of copperphthalocyanine-3-sulphonic acid- (3""4'"'-sulphophenylamide)-3,3",3"'-trisulphonic acid in 800 parts of water is run slowly into the suspension at 0.5". The pH of the reaction mixture is maintained between 5 and 6 by the gradual addition of sodium carbonate solution. As soon as no further sodium carbonate solution is consumed, a neutral solution of 106.6 parts of copper phthalocyanine-4- sulphonic acid-(3""-amino-4''-sulphophenyl amide)-4,4" ,4"'-tn'su1phonic acid in 1,200 parts of water is added. The
temperature is raised slowly to 50 while the pH is kept PRINTING METHOD A mercerized cotton fabric is printed with a paste of the following composition:
30 parts of the dye of Example 1 parts of Urea 395 parts of water 450 parts of 3% sodium algin 10 parts of sodium l-nitrob 15 parts of sodium carbonate 1,000 pans ate thickening enzene-3-sulphonate total:
The printed fabric is dried, steamed for 10 minutes at lO2-10 4, rinsed with cold and warm water, soaped at the boil, rinsed again and dried. A turquoise print of good light and wet fastness is obtained.
EXAMPLE 2 18.4 parts of cyanuric chloride are dissolved in 70 parts of acetone at 3035 and the solution is added with vigorous stirring to 300 parts of ice-water to give a suspension. To this is added slowly at 0-5 a neutral solution of 197.2 parts of copper phthalocyanine-S-sulphonic acid-(3"-amino-phenylamide)-3',3",3"'trisulphonic acid in 1,500 parts of water. The pH value is maintained at 5-6 by controlled addition of sodium carbonate solution. As soon as the rate of reaction decreases, the temperature is raised to 50 and the pH adjusted to 7.0-7.5 so that the reaction proceeds to the endpoint. Sodium chloride is added for complete precipitation of the dye, which is then filtered ofi and dried at 7080 with vacuum. The reactive .dye obtained is again of turquoise blue hue and, in view of its excellent build-up properties, it is very suitable for exhaustion dyeing.
