Description:
DETAILED DESCRIPTION OF THE INVENTION 
     This invention relates to azo dyes and more particularly, to novel red azo dyes which have excellent fastness to water and light as well as in dyeing affinity and solubility in liquids, and a method for the preparation of such dyes. 
     Several red direct dyes which have excellent wet fastness are used in the art (for example, in U.S. Pat. No. 1,509,442). In general, however, such direct cotton dyes are defective in other important properties such as dyeing affinity and/or solubility in liquids, so that they have only limited uses. Accordingly, there has been a strong demand for red azo dyes having excellent solubility and dyeing affinity as well as wet fastness. 
     It is therefore an object of the present invention to provide azo dyes which will overcome the above-mentioned defects. 
     It is a further object of the present invention to provide azo dyes which have excellent wet fastness and a red color which can serve as one of the primary colors. 
     It is another object of the present invention to provide water-soluble red azo dyes. 
     It is still another object of the present invention to provide a method for the preparation of red azo dyes of the nature as mentioned above. 
     According to the present invention, there are provided red azo dyes having the following formula (1) ##STR2## wherein X represents a benzene nucleus with or without one or more of substituents selected from the group consisting of an alkyl group containing 1 or 2 carbon atoms, an alkoxyl group containing 1 to 2 carbon atoms, chlorine, sulfonic acid group, amino group, hydroxyl group, sulfonamide group, acetylamino group, nitro group, carboxyl group and benzothiazole residue; however, no substitutent which is capable of forming a copper complex, such as a hydroxyl group, carboxyl group, methoxy group, ethoxy group or the like should be present in ortho position to the amino group of the benzene nucleus to be diazotized); a naphthalene ring substituted with sulfonic acid group; stilbene having sulfonic acid group and nitro group; and azobenzene or benzeneazonaphthalene with or without sulfonic acid group, acetylamino group, methyl group and/or methoxy group; Y represents an alkylamino group containing 1 to 3 carbon atoms, an alkanolamino group containing 2 to 3 carbon atoms, an amino group, --HNCH 2  COOH, --NHCH 2  CH 2  SO 3  H, a morpholine residue, an aniline or phenol residue with or without an alkyl group containing 1 or 2 carbon atoms, an alkoxyl group containing 1 to 2 carbon atoms, chlorine, an amino group, acetylamino group, sulfonic acid group, or sulfonamide group, N-methylaniline residue, or a naphthylamine residue having a substituted sulfonic acid group; W represents hydrogen or a sulfonic acid group; Z represents a sulfonic acid group attached to the meta or para position to the azo group; and R 1  and R 2  independently represent hydrogen or a methyl. In this connection, though the azo dyes of formula (1) are expressed in the form of free sulfonic acid, the same may be in the form of a sulfonate such as of an alkali metal including sodium, potassium, or the like, or ammonium. 
     More particularly, among the dyes of formula (1), higher wet fastness (according to JIS L 0844 A-4 method) is obtained with sulfonic acid dyes represented by the following formula (2) in the form of a free acid, i.e., ##STR3## wherein A represents a 4-methoxy-2-sulfophenyl group, 4-methoxy-3-sulfophenyl group, 2- or 3-sulfophenyl group, tolyl group, 4-nitro-2,2&#39;-disulfostilbyl group, sulfonaphthyl group or 4-(4&#39;-sulfophenylazo)-2-sulfophenyl group; B represents a monoethanolamine group, diethanolamine group, morpholino group, or N-methylamino group; W represents hydrogen or a sulfonic acid group; and Z represents a sulfonic acid group attached to the meta or para position to the azo group).

     The novel red azo dyes of the present invention expressed by the afore-mentioned formula (1) are water-soluble and have excellent affinity for materials such as fibres and paper, particularly with cellulose materials. Furthermore, materials dyed with the red azo dyes of the present invention have excellent fastness to light, and particularly wet fastness, as compared with materials dyed with use of known red direct dyes. 
     In dyeing fibrous materials with the dyes of the present invention, any conventional dyeing process such as a dip dyeing process, a continuous dyeing process, or a printing process may be employed. With the dip dyeing process, for example, the dye of formula (1) of the present invention is added to a dyeing bath which contains a 5 - 30 % sodium chloride or calcined Glauber&#39;s salt aqueous solution in an amount 3 - 60 times the amount of a fibrous material to be dyed. Then, the fibrous material is dipped in the dyeing bath, which is heated and agitated at 50° - 130° C for 30 -  120 min. In the dip dyeing process, a dyeing assistant may be added to the dyeing bath, if desired. With the continuous dyeing process, a fibrous material is padded by passing it through an aqueous solution of the dye of formula (1), followed by either batching the padded fibrous material at room temperature for 2 - 24 hours, by subjecting the resultant fibrous material to steaming at a temperature of 100° - 150° C for a short period of time, or by treating the resultant fibrous material in a 5 - 10 % sodium chloride or calcined Glauber&#39;s salt aqueous solution, which is heated at 80° - 100° C, for fixing the dye in or on the fibrous material. As necessary, the padding solution may contain the usual additives such as urea, a penetrating agent, and/or a reduction inhibitor. With the printing process, a color paste is first prepared with use of the dye of formula (1), a thickening agent and additives such as a reduction inhibitor, a solubilizer and the like. Then, the color paste is printed upon a fibrous material, followed by steaming the printed material at 100° - 150° C for 5 - 60 min. to fix the dye. 
     The materials dyed by any of the above-mentioned processes can be further improved in wash fastness and water fastness by fixing the dye with use of a commercially available fixing agent. 
    
    
     The present invention will be more particularly illustrated by the following examples. In the examples, parts or percentages are of proportions by weight. 
     EXAMPLE 1 
     3.7 parts of cyanuric chloride was added to a mixture of 50 parts of ice water and 0.1 part of Liponox RNA (a non-ionic active agent produced by The Lion Fat &amp; Oil Co., Ltd.) and was dispersed with vigorous agitation. To the resultant solution a solution, which contained 9.06 parts of the aminoazo compound of the following formula (10) ##STR11## dissolved in 150 parts of neutral water, was added dropwise over a period of 30 - 60 min. while maintaining the reaction temperature at 0° - 5° C. At the same time, a 10 % sodium carbonate solution was added dropwise into the solution to maintain the pH value thereof at 3 - 6. The reaction was allowed to proceed continuously for several hours until the unreacted aminoazo compound of formula (10) became undetectable. Then, 9.06 parts of an aminoazo compound having the following formula (11) ##STR12## and dissolved in 150 parts of neutral hot water was added to the reaction solution for further reaction while maintaining the temperature at 50° C. Simultaneously, a 10 % sodium carbonate solution was added to the reaction solution to maintain the pH value at 3 - 6. When the unreacted aminoazo of formula (11) became undetectable, 3.7 parts of monoethanolamine was further added to the solution and reacted at 90° - 95° C for 3 hours. Thereafter, sodium chloride was added to the reaction system to salt out the product, which was then filtered. The resultant cake-like product was then introduced into 400 parts of water and agitated for a short period of time. The resultant solution was heated to 95° C and was mixed with a solution containing 5.5 parts of crystalline copper sulfate, 30 parts of warm water and 6.1 parts of monoethanolamine, which mixture was allowed to react at 95° C for 3 hours to produce the copper complex salt. After completion of formation of the complex salt, sodium chloride was added to the reaction solution to salt out a dye, which was separated by filtration, dried and pulverized to obtain dark reddish brown powder. The dye had the following formula (12) ##STR13## The dye showed a dark red color when dissolved in water and a maximum absorbance at a wavelength of 524 mμ (in a 10 % pyridiene aqueous solution). Natural and regenerated cellulose such as cotton, flax, linen, viscose and staple fibre, and paper could be dyed to a bluish red color with use of the dye obtained. The resultant dyed materials had excellent wet fastness. 
     When the above process was repeated using cyanuric bromide instead of cyanuric chloride, similar results were obtained.

     EXAMPLE 21 
     Example 1 was repeated except that 4.78 parts of 6-amino-1-naphthol-3-sulfonic acid was used instead of the aminoazo compound of formula (10), to obtain a reaction solution containing 16.5 parts of a compound expressed by the following formula (13) ##STR46## To the reaction solution was added ice to cool the temperature of the reaction solution to 10° C and a diazo solution, which was obtained from 4.06 parts of 4-methoxyanilin-2-sulfonic acid, for reaction at 10° C with a pH value of 7 - 8 for 3 hours. Thereafter, the reaction solution was agitated at room temperature overnight to complete the coupling reaction. The resultant product was then treated in the same manner as in Example 1 for forming the copper complex salt of the product to obtain the dye of formula (12). 
     EXAMPLE 22 
     The same procedure as in Example 1 was repeated except that 4.78 parts of 6-amino-1-naphthol-3-sulfonic acid was used instead of the aminoazo compound of formula (11), to form a reaction solution containing 16 parts of a compound expressed by the following formula (14). ##STR47## To the reaction solution was added ice to cool the temperature of the reaction solution to 10° C. A diazo solution, which was formed from 4.06 parts of 2-methoxyaniline-5-sulfonic acid, was then added to the reaction solution, which was agitated at 10° C for 3 hours at a pH value of 7 - 8 and then further agitated at room temperature overnight to complete the coupling reaction. Thereafter, the same procedure as in Example 1 was repeated using monoethanolamine and the same copper-yielding agent to obtain the dye of formula (12). 
     EXAMPLE 23 
     1 part at the dye of the afore-mentioned formula (12) was mixed with 3 parts of calcined Glauber&#39;s salt and 1000 parts of water to prepare a dyeing bath of 50° C. 30 parts of spun viscose rayon clot was immersed in the bath, which was heated up to 90° C over a period of 15 min. The dyeing was continued for an additional 35 min. at 90° C and then the cloth was removed from the bath, washed and dried. The dried spun viscose rayon cloth showed a bluish red color and was excellent in fastness to light and water. 
     The thus dyed cloth was immersed in a bath, which contained 3 parts of Kayafix CD (a fixing agent produced by NIPPON KAYAKU CO., LTD.) and 1000 parts of water, at 60° C for 20 min., followed by washing and drying. This treatment improved the wet fastness of the cloth without impairing its originally dyed color. 
     The dye of formula (12) had a bluish red color, a high degree of solubility in water (100 g/l) and a high color value. The combination of the dye with other a dispersing dye was suitable for dyeing polyester-cellulose fibre blend in a single bath at high temperature. 
     The dye of formula (12) was found to belong to class B of the S.D.C., Clasification and to be of a high-temperature exhaustion type. 
     Viscose rayon which was dyed using the dye of formula (12) to a normal depth had good light fastness (i.e., the rating value of the dyed rayon was 7 when determined in accordance with a method as prescribed in Japanese Industrial Standards L-0841), and good in wash fastness (i.e., the change in a value of shade was 4 and the staining value was 3 - 4 when determined in accordance with a testing method using white viscose rayon as prescribed in Japanese Industrial Standards L-0844 A-2). Then, the dyed rayon was subjected to a fixing treatment using a polyamine-base fixing agent, Kayafix CD (produced by NIPPON KAYAKU CO., LTD.). The resultant rayon had excellent wash fastness (i.e., the change in a shade value was 4 - 5, and its staining value was 4 when determined in accordance with a testing method using white viscose rayon as prescribed in Japanese Industrial Standards L-0844 A-4). It was found that little change occurred in the shade of the dyed rayon by the fixing treatment.

The resultant solution was padded on cuprammonium rayon cloth, followed by steaming at 103° C for 3 min., washing and drying. The thus dried cupra cloth had a bluish red color and excellent fastness to light and water. 
     The dye itself had a bluish red color, a high degree of solubility in water (100 g/l) and a high color value. The combination of the dye with a dispersing dye was suitable for dyeing a polyester-cellulose fibre blend, in a single bath at a high temperature. 
     The dye of formula (15) belonged to class B of the S.D.C., Clasification and was a high-temperature exhaustion type. 
     Viscose rayon which was dyed using the dye of formula (15) to a normal depth had good light fastness (i.e., the rating value of the dyed rayon was 7 when determined in accordance with a method as prescribed in Japanese Industrial Standards L-0841), and good wash fastness (i.e., the change in a value of shade was 4 - 5 and a staining value was 3 - 4 when determined in accordance with a testing method using white viscose rayon as prescribed in Japanese Industrial Standards L-0844 A-2). Then, the dyed rayon was subjected to a fixing treatment using a polyamine-base fixing agent, Kayafix CD (produced by NIPPON KAYAKU CO., LTD.). The resultant rayon had excellent wash fastness (i.e., the change in a shade value was 4 - 5, and a staining value was 4 when determined in accordance with a testing method using white viscose rayon as prescribed in Japanese Industrial Standards L-0844 A-4). Thus, it was found that little change occurred in the shade of the dyed rayon by the fixing treatment. 
     EXAMPLE 25 
     10 parts of a dye expressed by the following formula (16) ##STR49## was dissolved in 340 parts of water and the resultant solution was mixed with 650 parts of a 3 % CMC paste and was used to print a cotton broad cloth by a screen printing process. The thus printed cloth was dried at room temperature and was subjected to steaming for 30 min. under a pressure slightly higher than 1 atm. using saturated steam vapor, and washed and dried. The resultant cloth exhibited a bright red color and had excellent fastness to light and water. 
     The dye itself had a bluish red color, a high degree of solubility in water (100 g/l) and a high color value. The combination of the dye with a dispersing dye was suitable for dyeing a polyester-cellulose fibre blend, in a single bath at a high temperature. 
     The dye of formula (16) belonged to class B of the S.D.C., Clasification and was a high-temperature exhaustion type.

     0.1 part of a dye expressed by the following formula (17) ##STR50## and 0.6 parts of calcined Glauber&#39;s salt were dissolved in 800 parts of water at 25° C. To the resultant solution was added 30 parts of L.B.KP. (bleached kraft pulp of hard wood, 310 cc. C.S.F. of beating degree). Thereafter, water was added to the solution to make the total amount 1000 parts. The bath was agitated for 20 min. while maintaining the temperature at 25° C. Then 0.3 parts of RF size 880 (a rosin-derivatives base size produced by Hamano Kogyo K. K.) were added. The resultant solution was agitated for 10 min. and 0.9 parts of crystalline aluminum sulfate were then added followed by agitation for 20 min. The thus dyed pulp was formed into paper by a conventional process with use using a TAPPI Standard Sheet Machine and dried to obtain red paper sheets which had excellent fastness to light and water. 
     The dye itself had a bluish red color, high solubility in water (100 g/l) and a high color value. The combination of the dye with a dispersing dye was suitable for dyeing polyester-cellulose fibre blend, in a single bath at a high temperature. 
     The dye of formula (17) belonged to class B of the S.D.C., Clasification and was a high-temperature exhaustion type. 
     Viscose rayon which was dyed using the dye of formula (17) to a normal depth had good light fastness (i.e., the rating value of the dyed rayon was 6 when determined in accordance with a method as prescribed in Japanese Industrial Standards L-0841), and good wash fastness (i.e., the change in the shade value was 4 and its staining value was 4 - 5 when determined in accordance with a testing method using white viscose rayon as prescribed in Japanese Industrial Standards L-0844 A-2). Then, the dyed rayon was subjected to a fixing treatment using a polyamine-base fixing agent, Kayafix CD (produced by NIPPON KAYAKU CO., LTD.). The resultant rayon had excellent wash fastness (i.e., the change in the shade value was 4 - 5, and its staining value was 4 - 5 when determined in accordance with a testing method using white viscose rayon as prescribed in Japanese Industrial Standards L-0844 A-4). Thus, it was found that little change occurred in the shade of the dyed rayon by the fixing treatment. 
     EXAMPLE 27 
     3.7 parts of cyanuric chloride was introduced into 50 parts of ice water and 0.1 part of Liponox RNA (a non-ionic active agent produced by Lion Fat &amp; Oil Co., Ltd.) with violent agitation to form a dispersion. To the dispersion was added, dropwise, a solution, which was obtained by dissolving in 150 parts of neutral water 8.46 parts of an aminoazo compound expressed by the following formula (18) ##STR51## at a reaction temperature of 0° - 5° C over a period of 30 to 60 min. At the same time, a 10% sodium carbonate solution was, added dropwise into the reaction solution to maintain the pH value at 3 - 6. The reaction was continued at 0° - 5° C for several hours until unreacted aminoazo compound became undetectable. Then, a solution, which was obtained by dissolving under neutral conditions in 150 parts of hot water 9.06 parts of an aminoazo compound having the following formula (19) ##STR52## was added to the reaction solution, the temperature of which was raised to 50° C. At the same time, a 10% sodium carbonate solution was added dropwise to the reaction solution to maintain the pH value at 3 - 6 and the reaction temperature was maintained at 50° C. When unreacted aminoazo compound of formula (19) was no longer detectable, 3.7 parts of monoethanolamine was added to the reaction solution for reaction at 90° - 95° C for 3 hours. To the reaction solution was further added sodium chloride to salt out the dye product, which was in turn was separated by filtration. The thus separated cake-like product was introduced into 400 parts of water and dispersed. The resultant dispersion was heated to 95° C and mixed with a solution composed of 5.5 parts of crystalline copper sulfate, 30 parts of warm water and 6.1 parts of monoethanolamine for reaction at 95° C for 3 - 4 hours. After completion of formation of the copper complex salt, sodium chloride was added to the reaction system to salt out the dye, which was filtered, dried and pulverized to obtain a dark red powdered compound of formula (16) ##STR53## The dye when dissolved in water gave a yellowish red color and showed a maximum absorbance at 519 mμ (when observed in a 10% pyridine aqueous solution). The dye was readily soluble in water and had excellent dyeing affinity for cellulose materials. Accordingly, the dye was capable of satisfactorily dyeing natural or regenerated cellulose materials such as cotton, viscose or staple fibre, or paper with a yellowish red color. The resultant dyed material had excellent wet fastness, i.e., spun rayon cloth which was dyed with a heavy shade and fixed with Kayafix CD passed the test of the JIS L 0844 A-4 method. Furthermore, the dye had various excellent properties: optimum fastness to perspiration, excellent fastness to light, small or no discoloration by fixing treatments, and excellent suitability for high temperature dyeing. Thus, the dye was usable as a wet-fast red dye suitable for use as one of the primary colors. 
     Furthermore, when the above process was repeated substituting cyanuric bromide for the cyanuric chloride, the same dye was obtained.

     EXAMPLE 88 
     The same procedure as in Example 27 was repeated except that 10.03 parts of a copper-containing aminoazo compound, which was obtained by treating an aminoazo compound having the following formula (22) with a copper yielding agent ##STR140## by a conventional method, was used instead of the aminoazo compound of formula (18), and 4.78 parts of 6-amino-1-naphthol-3-sulfonic acid was used instead of the aminoazo compound of formula (19). The resultant condensate was subjected to a coupling reaction with the diazonium salt obtained from aniline-2-sulfonic acid, and the coupled product was condensed with 3.7 parts of monoethanolamine to obtain a dye having the same structure as that produced in Example 27. 
     EXAMPLE 89 
     3.7 parts of cyanuric chloride was introduced into a mixture of 50 parts of ice water and 0.1 part of Liponox RNA (a non-ionic active agent produced by Lion Fat &amp; Oil Co., Ltd.) with vigorous agitation for dispersing. To the dispersion was added dropwise a solution, which was obtained by dissolving in 150 parts of neutral warm water 9.06 parts of an aminoazo compound having the following formula (23) ##STR141## for reaction at a temperature of 0° - 5° C over a period of 30 min. At the same time, a 10 % sodium carbonate solution was added dropwise to the reaction solution to maintain the pH value at 3 - 7. In this manner, the reaction was continued at 0° - 5° C for several hours until unreacted aminoazo compound was no longer detectable. Then, 11.62 parts of a copper-containing aminoazo compound, which was obtained by treating with copper sulfate a coupling product of a diazocompound of 2-hydroxylaniline -5-sulfonic acid and of 6-amino-1-naphthol-3, 5-disulfonic acid, and which is expressed by the following formula (24) ##STR142## was dissolved in 140 parts of neutral warm water. The solution was added to the reaction system, to raise the temperature of the system to 50° C. At the same time, a 10% sodium carbonate solution was added to the system to maintain the pH value at 3 - 6 while keeping the temperature at 50° C. When unreacted aminoazo compound of formula (24) was no longer detectable, 3.7 parts of monoethanolamine was added to the reaction system for reaction at 90° - 95° C for 3 hours, to which sodium chloride was added to salt out the product. The product was then separated by filtration, dried and pulverized to obtain a dark reddish brown powdered compound having the following formula (17) ##STR143## When the dye or compound was dissolved in water, the solution gave a bluish red color and the dye had a maximum absorbance at 520 mμ (when observed in a 10 % pyridine aqueous solution.) The dye had excellent solubility in water and belonged to B group of SDC classification. The use of the dye in accordance with a conventional dyeing process resulted in a natural or regenerated cellulose such as cotton, viscose or staple fibre or paper dyed in a vivid red color. The resultant dyed material had excellent wet fastness, i.e., spun rayon cloth which was dyed to a heavy shade and fixed with Kayafix CD, passed the test of JIS L 0844 A-4. Furthermore, the dye had various other excellent properties: optimum fastness to perspiration, excellent fastness to light, little or no discoloration by fixing treatments, excellent suitability for high temperature dyeing. Thus, the dye was usable as a wet-fast red dye suitable for use as one of the primary colors. When the above process was repeated using cyanuric bromide instead of cyanuric chloride, the same dye was obtained.

The resultant solution was agitated for reaction at 10° C for 3 hours at a pH value of 7 - 8, and further agitated at room temperature overnight to obtain a dye having the same structure as the product of Example 89. 
     EXAMPLES 122 - 138 
     The procedure of Example 121 was repeated using various different starting materials, to produce the dyes shown in Table 7. The hue of each dye thus obtained was determined in the same manner as in Example 23 - 26. The results are shown in Table 7.
