Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The invention relates to the technical field of the fiber-reactive dyes, in particular relates to a novel monoazo reactive red dyestuff. 
     2. Description of Related Art 
     The practice of dyeing with fiber-reactive dyes has led to heightened expectations of the quality of the dyeings. Consequently there continues to be a demand for novel fiber-reactive dyes that have improved properties. Especially in demand are red reactive dyes having high fastness properties. It is true that British Patent No. 836,248, U.S. Pat. No. 2,979,498 and European Patent Application Publication No. 0 070 806 disclose numerous red fiber-reactive dyes, but the fastness properties of the dyeings obtainable with these dyes, especially the lightfastness and the perspiration lightfastness, are in need of improvement. 
     U.S. Pat. No. 5,227,475 discloses fiber-reactive dyestuffs having the following formula:                           
     The practice of dyeing using reactive dyestuffs has improved the quality of the dyeings and the efficiency of the dyeing process. Reactive dyestuffs generally display good dyeing and fastness properties but the light fastness, alone and in presence of perspiration, of red fiber-reactive dyestuffs is generally only modest and in need of improvement.

     The dyestuffs of the present invention can be produced by the above methods, reaction conditions are fully described in the above description. The dyestuffs of the present invention can be purified by known processes such as spray drying, precipitation, or filtration. They can be in the form of powder, granules, particle or liquid and an auxiliary reagent, for example, retarding agent, leveling agent, assistant agent, surfactant agent, or dispersing agent may be added. 
     The dyestuffs of the present invention all contain at least one anionic group, such as a sulfonic acid group. For convenience they are expressed as free acid in the specification. When the dyestuffs of the present invention are manufactured, purified or used, they often exist in the form of water soluble salts, especially the alkaline metal salts, such as the sodium salt, lithium salt, potassium salt or ammonium salt, preferably sodium salt. 
     The dyestuffs of formula (I) in accordance with the present invention are fiber-reactive and useful for dyeing or printing hydroxyl group-containing and amide group-containing materials. 
     The dyestuffs of formula (I) according to the invention are suitable for dyeing and printing the various materials, such as silk, leather, wool, polyamide fibers and polyurethanes, and in particular all types of fiber materials containing cellulose. Examples of such fiber materials are the natural cellulose fibers, such as cotton, linen and hemp, as well as cellulose and regenerated cellulose. The dyestuffs of formula (I) are also suitable for dyeing or printing fibers which contain hydroxy groups and are contained in blended fabrics, for example mixtures of cotton with polyester fibers or polyamide fibers. 
     The dyestuffs according to the invention can be applied to the fiber material and fixed on the fiber in various ways, in particular in the form of aqueous dyestuff solutions and printing pastes. They are suitable both for the exhaust dyeing and for dyeing by the pad-dyeing process, in which the goods are impregnated with aqueous dyestuff solutions, if appropriate containing salts, and the dyestuff is fixed, after an alkali treatment or in the presence of alkali, if appropriate under the action of heat. The dyestuffs according to the invention are particularly suitable for the so-called cold pad-batch process, in which the dyestuff is applied to the padder together with the alkali and is then fixed by storage at room temperature for several hours. After fixing, the dyeings or prints are rinsed thoroughly with cold and hot water, if appropriate with addition of a dispersing agent which promotes diffusion of the non-fixed dye residues. 
     The present invention therefore also relates to the use of the compounds of the formula (I) according to the invention for dyeing (including printing) these materials and to processes for dyeing (and printing) such materials by a procedure which is customary per se, in which a compound of the formula (I) is employed as the coloring agent, by applying the compound of formula (I) to the material in an aqueous medium and fixing it on the material by means of heat or by means of an alkali or by means of both. 
     The dyestuffs of formula (I) are distinguished by a high reactivity, good fixing capacity and very good build-up capacity. The dyestuffs of the formula (I) can also exhibit excellent color-depth, level-dyeing and wash-off properties and high solubility as well as high exhaustion and fixation percentages. They can therefore be employed by the exhaust dyeing process at low dyeing temperatures and require only short steaming times in the pad-steam process. The degrees of fixing are high and the non-fixed portions can easily be washed out, the difference between the degree of exhaustion and the degree of fixing being remarkably small, i.e. the soaping loss is very low. The dyestuffs of formula (I) are also particularly suitable for printing, above all on cotton, and similarly also for printing nitrogen-containing fibers, for example wool or silk or blended fabrics which contain wool or silk. 
     The dyeings and prints produced on cellulose fiber materials with the dyestuffs according to the invention have a good depth of color and a high fiber-dyestuff bonding stability both in the acid and in the alkaline range, and furthermore good light-fastness, good perspiration-light fastness and very good wet-fastness properties, such as fastnesses to washing, water, seawater, cross-dyeing and perspiration, as well as a good fastness to pleating, fastness to ironing and fastness to rubbing. 
     The Examples that follow serve to illustrate the invention, which are only illustrative, but not limiting. The compounds are depicted in the formulae are shown in the form of free acids; in general, they are prepared and isolated in the form of their alkali metal salts and used for dyeing in the form of their salts. In the same way it is possible to use the starting compounds and components mentioned in the form of free acids in the examples below in particular the Table of examples, in the synthesis as such or in the form of their salts, preferably alkali metal salts. 
     The Examples that follow serve to illustrate the invention. Parts and percentages are by weight, unless otherwise stated. Parts by weight bear the same relation to parts by volume as the kilogram to the liter. 
     The absorption maxima (λ max) in the visible region reported for the compounds according to the present invention were determined from aqueous solutions of alkali metal salts. 
     EXAMPLE 1 
     A solution containing 4-nitroaniline-2-sulfonic acid (21.8 parts) and a 35% aqueous solution of sodium nitrite (21.7 parts) in water (150 parts) was introduced into a solution containing ice water (300 parts) and concentrated hydrochloric acid (35.5 parts), while controlling the temperature at 0 to 5° C., and the mixture was stirred for 1 hour at this temperature to effect diazotization. 
     Successively, after excess nitrous acid had been decomposed, 2-amino-8-hydroxynaphthalene-3,6-disulfonic acid (31.9 parts) was added to the reaction mixture, and the mixture was stirred for 12 hours at room temperature, thereby performing a coupling reaction. Thereafter, the reaction mixture was adjusted to pH 8 to 10, and mixed with sodium sulfide (10.7 parts), and the mixture was heated to 60° C. and stirred for 3 hours at this temperature to effect reduction of the nitro group. Then, the reaction mixture was mixed with sodium chloride (40 parts) to deposit crystals, which were collected on a filter and washed. The resulting wet cake was dissolved in water (400 parts). The solution was mixed with cyanuric chloride (16.7 parts), and the mixture was stirred for 5 hours at 0 to 10° C., while controlling the pH within a range of 4 to 5 using a 20% aqueous solution of sodium carbonate, thereby performing a first condensation compound of formula (1).                           
     EXAMPLE 2 
     To a solution containing the compound of Example 1 was added 27.8 parts of 1-N-ethylaminobenzene-3-β-sulfatoethylsulfone. The mixture was heated to 55° C., and was maintained at pH 4 to 5 for 5 hours. 
     To the resulting solution was added sodium chloride to precipitate the desired product of formula (2), (λmax=525 nm),                           
     EXAMPLE 3 to 33 
     The procedure described in Example 2 is repeated, reacting the compound of Example 1 with the following compounds, 3 to 33. As a result, bluish red (525±2 nm) monoazo derivatives are obtained.

     A solution containing 4-nitroaniline-2-sulfonic acid (21.8 parts) and a 35% aqueous solution of sodium nitrite (21.7 parts) in water (150 parts) was introduced into a solution containing ice water (300 parts) and concentrated hydrochloric acid (35.5 parts), while controlling the temperature at 0 to 5° C., and the mixture was stirred for 1 hour at this temperature to effect diazotization. 
     Successively, after excess nitrous acid had been decomposed, 2-N-methylamino-8-hydroxynaphthalene-3,6-disulfonic acid (33.3 parts) was added to the reaction mixture, and the mixture was stirred for 12 hours at room temperature, thereby performing a coupling reaction. Thereafter, the reaction mixture was adjusted to pH 8 to 10, and mixed with sodium sulfide (10.7 parts), and the mixture was heated to 60° C. and stirred for 3 hours at this temperature to effect reduction of the nitro group. Then, the reaction mixture was mixed with sodium chloride (40 parts) to deposit crystals, which were collected and washed. The resulting wet cake was dissolved in water (400 parts). The solution was mixed with cyanuric chloride (16.7 parts), and the mixture was stirred for 5 hours at 0 to 10° C., while controlling the pH within a range of 4 to 5 using a 20% aqueous solution of sodium carbonate, thereby performing a first condensation. To this reaction mixture was added an aqueous solution of 3.78 parts of cyanamide in about 100 parts of water, and the mixture is heated to 40˜60° C. and maintained at a pH 8.0 to 10.0 by means of a 20% aqueous solution of sodium carbonate until the reaction has ended after 6 to 7 hours, thereby performing a second condensation. 
     25.3 parts of 1-aminobenzeze-3-β-sulfatoethylsulfone were added to the above reaction mixture, and the resulting mixture was heated to 55° C., and maintained at pH 4 to 6 for 4 hours. To the resulting solution was added sodium chloride to precipitate the desired product of formula (119), (λmax=530 nm).

     EXAMPLE 194 
     To an aqueous mixture of the dichloro triazine described in example 119 was added 1-aminobenzeze-3-β-sulfatoethylsulfone (25.3 parts), and the mixture is heated to 55° C. and maintained at a pH 4 to 5 by means of a 20% aqueous solution of sodium carbonate until the reaction was complete after 3 to 5 hours. 
     18.5 parts of 3-carboxypyridine were added to the above reaction mixture, and the resulting mixture was heated to 85˜90° C. at pH 4 to 5 for 12 hours. To the resulting solution was added sodium chloride to precipitate the desired product of formula (194), (λmax=535 nm).                           
     EXAMPLE 195 to 268 
     In a similar manner compounds (195) to (268) were prepared. Each naphthol compound of formula (XI) shown in a second column of the following table was used in place of 2-N-methylamino-8-hydroxynaphthalene-3,6-disulfonic acid, and each compound of the formula (X) shown in a third column in place of 4-nitroaniline-2-sulfonic acid, 3-carboxypyridine as shown in a fourth column, and each aromatic amine compound of the formula(VIII) shown in a fifth column in place of 1-aminobenzeze-3-β-sulfatoethylsulfone, thereby obtaining the desired corresponding monoazo compound.

     EXAMPLE 269 
     2-Amino-8-hydroxynaphthalene-6-disulfonic acid (23.8 parts) was added to 4-nitro-2-sulphobenzene diazonium chloride prepared as in Example 1, and the mixture was stirred for 12 hours at room temperature, to effect coupling. The reaction mixture was then adjusted to pH 8 to 10, and mixed with sodium sulfide (10.7 parts), and the mixture was heated to 60.° C. and stirred for 3 hours at this temperature to reduce the nitro group. Then, the reaction mixture was mixed with sodium chloride (40 parts) to deposit a solid, which was collected and washed. The resulting wet cake was dissolved in water (400 parts). The solution was mixed with cyanuric chloride (16.7 parts), and the mixture was stirred for 5 hours at 0 to 10° C., while controlling the pH within a range of 4 to 5 using a 20% aqueous solution of sodium carbonate, thereby performing a first condensation. To this reaction mixture was added 1-N-ethylaminobenzene-3-β-sulfatoethylsulfone (27.8 parts), and the mixture is heated to 55° C. and maintained at a pH 4 to 5 by means of a 20% aqueous solution of sodium carbonate until the reaction has ended after 3 to 5 hours. 
     To the resulting solution is added sodium chloride to precipitate the desired product of formula (269), (λmax=518 nm),                           
     EXAMPLE 270 to 295 
     By a similar procedure compounds of examples 270 to 295 were prepared.
