Definitions
- This invention relates to an improved process for neu tral developing of azoic colors and to the compositions used therein.
- this invention relates to an improved process for neutral developing of azoic colors wherein the dyeing or printing composition contains a sulfonated long chain carboxylic acid and a Water soluble nitrogeneous oxygen-containing organic base.
- Prior art processes for developing azoic compositions may be broadly classified into acidic developing and neutral developing.
- the diazo compound and the coupling component are dissolved in a caustic alkali solution.
- the solution is thereafter made into a suitable paste by the addition of a thickening agent such as starch or gum tragacanth.
- a thickening agent such as starch or gum tragacanth.
- the dye is developed by exposing the textile to acidic steam.
- the acidic steam operates to split the diazo moiety, and the thus freed diazo couples with the coupling component to produce the color.
- acetic acid is used as the acid component in the steam.
- acidic developing produces the desired dyed effect, attendant therewith are .several disadvantages, primary of which is the offensive smell, irritating effect of the acid in the steam vapors, and corrosion of apparatus. Consequently, prior art workers have attempted to utilize a neutral steam developing process, thereby excluding the use of any acid.
- Another object of this invention is to provide a neutral developing azo dye composition and process which is remarkably effective in cleaving slow-splitting diazoamino compounds.
- a further object of this invention is to provide a neutral developing azo dye composition and process wherein the colors developed are as consistently as bright as that produced in the conventional acidic developing composition and process.
- Another object of this invention is to provide a neutral developing azo dye composition and process which can be employed with slow-splitting diazoamino compounds Which cannot be developed by the method described in United States Patent 2,232,405 which process is known as the RNA method.
- Another object of this invention is to provide a composition and process wherein azoic compositions can be developed by a heat treatment.
- compositions containing a sulfonated long-chain carboxylic acid and a volatile water-soluble nitrogenous oxygen-containing organic base are containing a sulfonated long-chain carboxylic acid and a volatile water-soluble nitrogenous oxygen-containing organic base.
- the volatile water-soluble nitrogenous oxygen-containing organic bases can be those recited in United States Patent No. 2,232,405, which patent is hereby incorporated by reference.
- Exemplary of the bases recited therein are ethylaminoethanol, diethylaminoethanol, N-propylaminoethanol, dimethylaminoethanol, dimethylaminobutanone, diethylaminoethanol methyl ether, N-hydroxyethylpyrrolidine, isobutylaminoethanol, isopropylaminoethanol. and dipropylam-inoethanol.
- the sulfonated long-chain carboxylic acids are preferably the C to C sulfonated alkyl carboxylic acids such as oc-SlllfOltlllflC acid, u-sulfotridecoic acid, a-sulfomyristic acid, ⁇ oc-sulfopentadecanoic acid, a-sulfopalmitic acid, a-sulfomargaric acid, and a-sulfostearic acid.
- C to C sulfonated alkyl carboxylic acids such as oc-SlllfOltlllflC acid, u-sulfotridecoic acid, a-sulfomyristic acid, ⁇ oc-sulfopentadecanoic acid, a-sulfopalmitic acid, a-sulfomargaric acid, and a-sulfostearic acid.
- sulfonated long-chain alkyl carboxylic acids having from 12 to 18 carbon atoms is intended to include those compounds having one or more substituted sulfonated groups on any of the carbon atoms such as, for example, the p, 'y, 6, etc., position.
- the choice of acid and the position and number of sulfonated groups are dependent, for the most part, on prevailing economic considerations and the availability of the particular acid utilized.
- the preferred method of carrying out this invention is to combine the oxygen-containing volatile amine and sulfonated alkyl carboxylic acid to produce a composition which in turn is combined with an alkaline solution which comprises approximately equal amounts of a stabilized diazoamino compound and an azoic coupler.
- This solution is usually thickened with starch tragacanth, Keltex gum, etherified starch or similar thickeners to printing consistency, printed on the fabric and subjected to neutral steam to develop color, or if desired subjected to dry heat to develop color.
- the amine may be added to the azoic solution followed by addition of the sulfonated alkyl carboxylic acid under agitation.
- additives may be included in the solution such as dispersants, solvents, urea, formaldehyde and the like.
- the amount of the oxygen-containing amine and sulfonated alkylcarboxylic acid may vary. It has been found, for example, that .25 to 1.5 parts of oxygen-containing amine and .01 to .5 part of sulfonated alkylcarboxylic acid, to 1 part of color component provide satisfactory results.
- the strong organic acid should have an ionization constant greater than about 1.8X10- In other words, the strong acid should be stronger than acetic acid.
- Such acids include monochloroacetic acid, glycollic acid, diglycollic acid, oxalic acid and the like. In using such acids, 5 to 50% of the sulfonated long-chain carboxylic acid is replaced in the formulations by the strong acid.

In acidic developing the diazo compound and the coupling component are dissolved in a caustic alkali solution. The solution is thereafter made into a suitable paste by the addition of a thickening agent such as starch or gum tragacanth. After the paste is applied to the textile. as by printing, the dye is developed by exposing the textile to acidic steam. The acidic steam operates to split the diazo moiety, and the thus freed diazo couples with the coupling component to produce the color. Generally, acetic acid is used as the acid component in the steam. While acidic developing produces the desired dyed effect, attendant therewith are .several disadvantages, primary of which is the offensive smell, irritating effect of the acid in the steam vapors, and corrosion of apparatus. Consequently, prior art workers have attempted to utilize a neutral steam developing process, thereby excluding the use of any acid.
Various processes for the neutral developing of azoic dyes have been utilized by prior art Workers. The basic approach has been the use of an alkaline base which, after printing, evaporates on exposure to neutral steam, thereby lowering the pH and enabling the diazo to split and couple with the coupling component and subsequently produce the color. These processes include the addition to the dye preparation of organic acids, phosphoric acid and salts of acids as shown in United States Patent No. 1,951,571; the use of amine salts and amides in the print composition as illustrated in United States Patent No. 2,008,966; the replacement of caustic alkali by a volatile amine, such as diethylamine, as taught by United States Patent No. 2,125,087; and the use of an oxygen containing Water-soluble nitrogeneous organic base, such as diethylaminoethanol, disclosed in United States Patent No. 2,232,405.
All of the neutral developing techniques described above suffer from several disadvantages. None of the methods, for example, are satisfactory for use with slow splitting diazo compounds, such as S-chloro-o-toluidine diazo stabilized with sarcosine, and S-chloro-o-anisidine diazo stabilized with sarcosine. Furthermore, the shades are duller than when the same dyestulf components are developed in acid steam. The duller shades are attributable primarily to slow coupling. The pH is usually higher in rent 3,436,168 Patented Apr. 1, 1969 neutral developing than in acidic developing and therefore dissociation of the diazoamino compound is slow, coupling is slow and decomposition of diazo is high.
While this method has been found advantageous when applied to neutral developing of azoic dyes, that is by developing the color by ageing in the presence of neutral steam, it has an added feature that it is also suitable for heat developing of azoic dyes, that is by subjecting the printed or dyed fabric to a temperature of 200-425 F. to develop color. It is especially useful in the Thermosol method wherein the printed or dyed fabric is dried and then subjected to a temperature of from about ZOO-450 F. for from about 15 seconds to 2 minutes.
It has been found in accordance with the present invention that, by using a printing or dyeing composition containing both a sulfonated long-chain carboxylic acid and an oxygen-containing water soluble nitrogenous organic base, the disadvantages of the prior art neutral developing processes may be overcome.
In those cases where the diazoamino cleaves with great difficulty it has been found advantageous to replace part of the sulfonated long-chain carboxylic acid with a strong organic acid.
Accordingly, it is an object of this invention to provide a novel neutral developing azo dye composition and process for using the same.
Another object of this invention is to provide a neutral developing azo dye composition and process which is remarkably effective in cleaving slow-splitting diazoamino compounds.
A further object of this invention is to provide a neutral developing azo dye composition and process wherein the colors developed are as consistently as bright as that produced in the conventional acidic developing composition and process.
Another object of this invention is to provide a neutral developing azo dye composition and process which can be employed with slow-splitting diazoamino compounds Which cannot be developed by the method described in United States Patent 2,232,405 which process is known as the RNA method.
Another object of this invention is to provide a composition and process wherein azoic compositions can be developed by a heat treatment.
These and other objects are accomplished by a composition containing a sulfonated long-chain carboxylic acid and a volatile water-soluble nitrogenous oxygen-containing organic base.
The volatile water-soluble nitrogenous oxygen-containing organic bases can be those recited in United States Patent No. 2,232,405, which patent is hereby incorporated by reference. Exemplary of the bases recited therein are ethylaminoethanol, diethylaminoethanol, N-propylaminoethanol, dimethylaminoethanol, dimethylaminobutanone, diethylaminoethanol methyl ether, N-hydroxyethylpyrrolidine, isobutylaminoethanol, isopropylaminoethanol. and dipropylam-inoethanol.
The sulfonated long-chain carboxylic acids are preferably the C to C sulfonated alkyl carboxylic acids such as oc-SlllfOltlllflC acid, u-sulfotridecoic acid, a-sulfomyristic acid, \oc-sulfopentadecanoic acid, a-sulfopalmitic acid, a-sulfomargaric acid, and a-sulfostearic acid. In addition to the ix-sulfonated carboxylic acids disclosed above, the term sulfonated long-chain alkyl carboxylic acids having from 12 to 18 carbon atoms is intended to include those compounds having one or more substituted sulfonated groups on any of the carbon atoms such as, for example, the p, 'y, 6, etc., position. The choice of acid and the position and number of sulfonated groups are dependent, for the most part, on prevailing economic considerations and the availability of the particular acid utilized.
The preferred method of carrying out this invention is to combine the oxygen-containing volatile amine and sulfonated alkyl carboxylic acid to produce a composition which in turn is combined with an alkaline solution which comprises approximately equal amounts of a stabilized diazoamino compound and an azoic coupler. This solution is usually thickened with starch tragacanth, Keltex gum, etherified starch or similar thickeners to printing consistency, printed on the fabric and subjected to neutral steam to develop color, or if desired subjected to dry heat to develop color.
As an alternative, the amine may be added to the azoic solution followed by addition of the sulfonated alkyl carboxylic acid under agitation.
Other additives may be included in the solution such as dispersants, solvents, urea, formaldehyde and the like.
The amount of the oxygen-containing amine and sulfonated alkylcarboxylic acid may vary. It has been found, for example, that .25 to 1.5 parts of oxygen-containing amine and .01 to .5 part of sulfonated alkylcarboxylic acid, to 1 part of color component provide satisfactory results.
In those cases where the diazoamino cleaves with great difiiculty it has been found that splitting is easier and faster if part of the sulfonated long chain carboxylic acid is replaced by a strong organic acid. The strong organic acid should have an ionization constant greater than about 1.8X10- In other words, the strong acid should be stronger than acetic acid. Such acids include monochloroacetic acid, glycollic acid, diglycollic acid, oxalic acid and the like. In using such acids, 5 to 50% of the sulfonated long-chain carboxylic acid is replaced in the formulations by the strong acid.
The parts indicated above and throughout the specifica tion and claims are parts by weight.
