     The dyes represented by the general formula (I) as described hereinbefore can be easily prepared by reacting diazo compounds represented by the general formula (IX): ##STR16## (wherein D, ##STR17## are the same as described hereinbefore) with, for example, compounds represented by the general formula (X): ##STR18## (wherein R 1  and R 2  are the same as described hereinbefore). For example, a disazo compound represented by the general formula (IX) is reacted with from 1 to 1.2 moles per mole of the disazo compound of a difluorotriazine compound represented by the general formula (X) by heating them at a temperature of from room temperature to 90° C. for 0.4 to 5 hours in an organic solvent, e.g., acetone, methyl ethyl ketone, toluene, nitrobenzene, dioxane, N,N-dimethylformamide, N-methyl-2-pyrrolidone, or dimethyl sulfoxide, in the presence as an acid binding agent of from 1 to 2 moles per mole of the disazo compound of a tertiary amine, e.g., triethylamine, tributylamine, or N,N-diethylaniline, or an inorganic base, e.g., potassium carbonate or potassium hydrogencarbonate. The resulting reaction solution is cooled and poured into a, for example, water. By separating the precipitate thus formed by techniques such as filtration and centrifugal separation, there can be almost quantitatively obtained a disazo dye represented by the general formula (I). 
     Cellulose-containing fibers which are dyed using the dyes of the invention include fibers such as natural fibers, e.g., cotton and jute, semi-synthetic fibers, e.g., viscose rayon and copper ammonia rayon, and partially aminated or acylated cellulose fibers, and their woven and unwoven fabrics, and so forth. In addition, mixed fibers of the above-described fibers and other fibers, such as polyester fibers, cation dyeable polyester fibers, anion dyeable polyester fibers, polyamide fibers, wool, acryl fibers, urethane fibers, diacetate fibers, and triacetate fibers, and their fabrics can be used. Of these fibers, cellulose fibers and mixed fibers of cellulose fibers and polyester fibers, and their fabrics are particularly suitable for dyeing with the dyes of the invention. 
     In the practice of dyeing, it is desirable for the dyes represented by the general formula (I) to be finely dispersed in a medium to the extent that the resulting particle size is from 0.5 to 2μ. This can be achieved by various techniques such as a method in which a water-soluble dispersant, such as a nonionic surface active agent, e.g., a Pluronic surface active agent, or an anionic dispersant, e.g., sodium ligninsulfonate or a sodium salt of a naphthalenesulfonic acid-formalin condensate, is employed and the dyes are finely dispersed in water by the use of a grinder, such as a sand grinder and a mill; a method in which a water sparingly soluble or water insoluble dispersant, such as a compound prepared by adding a lower molar amount of ethylene oxide to sulfosuccinic acid ester, nonylphenol or the like, is employed, and the dyes are finely dispersed in a solvent other than water, such as alcohols, e.g., ethyl alcohol, isopropyl alcohol, and polyethylene glycol, ketones, e.g., acetone and methyl ethyl ketone, hydrocarbons, e.g., n-hexane, toluene, xylene, and mineral turpentine, halogenated hydrocarbons, e.g., tetrachloroethylene, esters, e.g., ethyl acetate and butyl acetate, ethers, e.g., dioxane, and tetraethylene glycol dimethyl ether, and their mixtures; and a method in which the dyes are finely dispersed in a mixed solvent of water and a solvent compatible in water in any proportion, selected from the above-described solvents. 
     This fine dye dispersion can be used as such as a padding bath for use in a padding dyeing method, or as a printing color paste for use in a printing method. In practical use, however, the fine dye dispersion is usually diluted with water, a mixed solvent of water and a solvent compatible with water in any proportions, or an o/w type or w/o type emulsion in which the oil phase is a petroleum hydrocarbon, such as mineral turpentine, or a halogenated hydrocarbon, such as tetrachloroethylene, to a level determined depending on the desired dyeing concentration. 
     In the preparation of such padding baths or printing color pastes, a cellulose fiber-swelling agent may be added in order to perform dyeing advantageously, or an alkali metallic compound, an organic epoxy compound, an organic vinyl compound or the like may be added as an acid coupler for the purpose of accelerating the reaction between the dye and cellulose fiber. 
     Alkali metallic compounds which can be used include alkali metal carbonic acid salts and, in addition, alkali metal hydrocarbonic acid salts, alkali metal phosphoric acid salts, alkali metal boric acid salts, alkali metal silicic acid salts, alkali metal hydroxides, alkali metal aliphatic acid salts, e.g., alkali metal acetic acid salts, and alkali precursors, such as sodium trichloroacetate and sodium acetoacetate, which liberate alkalis on heating in the presence of water. The amount of the alkali metallic compound being used is usually sufficient to be such that the pH of the padding bath or printing color paste is from 7.5 to 8.6. 
     Organic epoxy compounds which can be used include ethylene glycol diglycidyl ether and polyethylene glycol diglycidyl ether having an average molecular weight of from 150 to 400. Organic vinyl compounds which can be used include ethylene glycol diacrylate, and polyethylene glycol diacrylate or dimethacrylate having an average molecular weight of from 150 to 400. The amount of the organic epoxy compound or organic vinyl compound being used is from about 3 to 6% by weight based on the padding bath or printing color paste. 
     In order to prevent dry migration in the course of padding dyeing, or to regulate the color paste viscosity to the optimum level in various printing methods, a tackifier such as a water soluble polymer, e.g., sodium alginate, may be added. 
     The preparation of the padding bath or printing color paste is not limited to the above described method. Also, it is not always required for the cellulose swelling agent and acid binding agent to be present in the padding bath or printing color paste, and they may be added to fibers in advance. 
     Any cellulose fiber-swelling agents can be used in the invention as long as they have a boiling point of at least 150° C. and have the effect of swelling cellulose fibers. Examples are ureas such as N,N,N&#39;,N&#39;-tetramethylurea, polyhydric alcohols such as polyethylene glycol and polypropylene glycol, and their derivatives. Of these compounds, polyhydric alcohol derivatives which are prepared by dimethylating or diacetylating both terminal hydroxy groups of polyethylene glycol, polypropylene glycol, etc., having an average molecular weight of from about 200 to 500, and which are inactive with the reactive groups of dyes are particularly preferred to use as cellulose fiber-swelling agents. 
     The amount of the cellulose fiber-swelling agent being used is preferably from about 5 to 25% by weight, preferably from about 8 to 15% by weight, based on the padding bath or printing color paste. 
     The above-described cellulose-containing fibers are dyed using the dyes of the invention in the usual manner. For example, a cellulose-containing fiber material is impregnated or printed with a padding bath or printing color paste as prepared by the above-described method and dried and, thereafter, it is heat-treated with hot air or super heated steam maintained at 160° to 220° C. for 30 seconds to 10 minutes, or treated with high pressure saturated steam maintained at 120° to 150° C. for 3 to 30 minutes and then washed with hot water, or an o/w type or w/o type emulsion washing bath in which the oil phase is a halogenated hydrocarbon, such as tetrachloroethylene, or washed by the usual dry cleaning procedure. 
     In accordance with the above-described method, there can be obtained a dyed product which is sharp in color and uniformly dyed, and which has good light fastness and moisture fastness. 
     The following examples are given to illustrate the invention in greater detail. All parts are by weight.

     The printing color paste thus prepared was printed on a polyester/cotton mixed cloth (mixing ratio: 65/35) by the use of a screen printing machine, was subjected to preliminarily drying at 80° C. for 3 minutes, and then was fixed by dry heating at 215° C. for 90 seconds. After washing with water, the cloth was subjected to soaping using a washing solution containing 2 g/l of a nonionic surface active agent (Scourol #900 (trade name), produced by Kao Soap Co., Ltd.) at a bath ratio of 1:30 at a temperature of 80° C. for 20 minutes, and there was thus obtained a yellow brown dyed product having excellent light fastness and wet color fastness. 
     The dye used in this example was prepared as follows: 
     In a mixture of 50 ml of N-methyl-2-pyrrolidone and 1.5 g of triethylamine was dissolved 3.52 g of dye represented by the formula: ##STR20## and 2.6 g of 2,4-difluoro-6-di(n-butyl)aminotriazine was then added thereto. The resulting mixture was stirred at room temperature for 2 hours to achieve a condensation reaction. The reaction solution was poured into 500 ml of water, and the precipitate thus obtained was separated by filtration, washed with water, and then dried at room temperature by the use of a vacuum dryer.

Thereafter, a washing treatment was performed in the same manner as described in Example 1, and there was thus obtained a yellow dyed product having excellent light fastness and wet color fastness. 
     The dye used in this example was prepared as follows: 
     A dye represented by the formula: ##STR22## was reacted with 2,4-difluoro-6-diisopropylaminotriazine at room temperature in dimethyl sulfoxide by the use of tri-n-butylamine as an acid binding agent to obtain the dye represented by the above-described formula. For this dye, λ max  (acetone) was 383 nm.

     EXAMPLE 7 
     A dye composition consisting of 15 parts of disazo dye represented by the following formula: ##STR185## 15 parts of a naphthalenesulfonic acid-formaldehyde condensate, and 70 parts of water was processed by the use of a paint shaker as a finely dispersing apparatus to prepare a dye dispersion. This dye dispersion was used to prepare a printing color paste having the following composition:

     The printing color paste thus prepared was printed on a polyester/cotton mixed cloth (mixing ratio: 65/35) by the use of a screen printing machine, dried at 80° C. for 3 minutes, and then fixed by dry heating at 215° C. for 90 seconds. After washing with water, the cloth was subjected to soaping using a washing solution containing 2 g/l of a nonionic surface active agent (Scourol #900 (trade name), produced by Kao Soap Co., Ltd.) at a bath ratio of 1:30 and at a temperature of 80° C. for 20 minutes. There was thus obtained an orange dyed product having excellent light fastness and wet color fastness. 
     The dye used in this example was prepared as follows: 
     In 50 ml of a 50% by volume aqueous solution of acetic acid was dissolved 2.13 g of 4amino-4&#39;-hydroxyazobenzene, and 3 ml of hydrochloric acid was then added thereto. The resulting mixture was cooled to 5° C. or less, and 0.7 g of sodium nitrite was then added thereto. During this time, the temperature was regulated so as not to exceed 5° C. The thus obtained diazonium salt solution was added to 2.4 g of an aqueous solution of acetoacetic acid-2,4-dimethoxyanilide at a temperature of 5° C. or less while regulating so that the pH was maintained at 10. The disazo compound thus precipitated was separated by filtration, washed with water, and then dried. A mixture of 4.61 g of the above obtained dye, 2.1 g of 2,4-difluoro-6-(diethylamino)triazine, 1.0 g of triethylamine, and 1.0 g of anhydrous potassium carbonate was added to 100 ml of acetone and heated at reflux for 3 hours to achieve a condensation reaction. The reaction solution was added dropwise to 1,000 ml of water, and the thus formed precipitate was separated by filtration, washed with water, and then dried at room temperature. There was thus obtained 6.1 g of dark yellow powder of the dye represented by the above described formula (yield: 92%). For this dye, λ max  (acetone) was 409 nm. 
     EXAMPLE 8

     The thus prepared printing color paste was printed on a cotton broad (cotton yarn number: 40) which had been subjected to a silket processing, by the use of a screen printing machine, was subjected to preliminarily drying at 80° C. for 3 minutes, and then was treated using super heated steam at 185° C. for 7 minutes. Thereafter, the same washing treatment as in Example 1 was performed, and there was thus obtained an orange dyed product having excellent light fastness and wet color fastness. 
     The dye used in this example was prepared as follows: 
     A dye was prepared by diazonating 4-amino-5-methyl-4&#39;-hydroxyazobenzene and then coupling the resulting diazonated compound to acetoacetic acid anilide in accordance with the method as described in Example 1. The dye thus formed was then reacted with 2,4-difluoro-6-[di(n-propyl)amino]triazine in N-methyl-2-pyrrolidone by the use of triethylamine as an acid-binding agent to obtain the desired dye. For this dye, λ max  (acetone) was 409 nm.

     The color paste thus prepared was printed on a polyester/cotton mixed cloth (mixing ratio: 65/35) by the use of a screen printing machine, dried at 100° C. for 2 minutes, and then treated using super heated steam at 175° C. for 7 minutes. Thereafter, the cloth was washed with a heated tetrachloroethylene bath containing a small amount of water and dried, and there was thus obtained an orange dyed product which had excellent light fastness and wet color fastness, and was not stained in the white background. 
     The dye used in this example was prepared as follows: 
     2&#39;-Acetylamino-4&#39;-amino-3-hydroxyazobenzene was diazonated and then coupled to acetoacetic acid-2-ethoxyanilide in accordance with the method as described in Example 7 to prepare a dye which was then reacted with 2,4-difluoro-6-piperidinotriazine in accordance with the method as described in Example 7 to prepare the desired dye. For this dye, λ max  (acetone) was 413 nm.

     A polyester/cotton mixed cloth (mixing ratio: 65/35) was impregnated with the above prepared padding bath and squeezed at a squeezing ratio of 45% and, thereafter, it was dried at 100° C. for 2 minutes and fixed by dry heating at 200° C. for 1 minute. The cloth was then washed with a hot ethanol bath, and there was thus obtained an orange dyed product having excellent light fastness and wet color fastness. 
     The dye used in this example was prepared in accordance with the method as described in Example 7. For this dye, λ max  (acetone) was 412 nm. 
     EXAMPLE 11 
     Printing was performed in the same manner as in Example 7 except that a nylon/rayon mixed cloth (mixing ratio: 50/50) was used, and the dry heating fixing temperature was 185° C. There was thus obtained a reddish orange printed product having good wet color fastness and light fastness.

     The thus prepared printing color paste was printed on a polyester/cotton mixed cloth (mixing ratio: 65/35) by the use of a screen printing machine, was subjected to preliminarily drying at 80° C. for 3 minutes, and then was fixed by dry heating at 215° C. for 90 seconds. After washing with water, the cloth was subjected to soaping using a washing solution containing 2 g/l of a nonionic surface active agent (Scourol #900 (trade name), produced by Kao Soap Co., Ltd.) at a bath ratio of 1:30 at 80° C. for 20 minutes. There was thus obtained an orange dyed product having excellent light fastness and wet color fastness. 
     The dye used in this example was prepared as follows: 
     In a 50% aqueous solution of acetic acid was dissolved 2.13 g of 4-amino-4&#39;-hydroxyazobenzene, and 3 ml of hydrochloric acid was added thereto. The resulting mixture was cooled to 5° C. or less. Then, 0.7 g of sodium nitrite was added to the mixture while controlling so that the temperature did not exceed 5° C. The thus formed diazonium salt solution was added to a solution of 1.73 g of 1-phenyl-3-methyl-5-pyrazolone in a diluted aqueous sodium hydride solution at a temperature of 5° C. or less while controlling so that the pH was within the range of from 8 to 9. The disazo compound precipitated was separated by filtration, washed with water, and dried. A mixture of 3.97 g of the dye thus prepared, 2.1 g of 2,4-difluoro-6-(diethyl)aminotriazine, 1.0 g of triethylamine, and 1.0 g of anhydrous potassium carbonate was added to 100 ml of acetone and heated to reflux for 3 hours to achieve a condensation reaction. The reaction solution was added dropwise to 1,000 ml of water. The precipitate formed was separated by filtration, washed with water, and then dried at room temperature. There was thus obtained 5.2 g of yellow powder of the dye represented by the above described formula. For this dye, λ max  (acetone) was 422 nm.

     The thus prepared printing color paste was printed on a cotton broad (cotton yarn number: 40) which had been subjected to a silket processing, by the use of a screen printing machine, was subjected to intermediate drying at 80° C. for 3 minutes, and then was treated using super heated steam at 185° C. for 7 minutes. Thereafter, a washing processing was performed in accordance with the method as described in Example 13, and there was thus obtained an orange dyed product having excellent light fastness and wet color fastness. 
     The dye used in this example was prepared as follows: 
     4-Amino-4&#39;-hydroxyazobenzene was diazonated and then coupled to 1-(m-chlorophenyl)-3-methyl-5-pyrazolone in accordance with the method as described in Example 13 to prepare a dye. The thus prepared dye was reacted with 2,4-difluoro-5-[di(n-propyl)amino]triazine in N-methyl-2-pyrrolidone by the use of triethylamine as an acid binding agent to prepare the desired dye. For this dye, λ max  (acetone) was 416 nm.

This dye dispersion was used to prepare a padding bath having the following composition: 
     
         ______________________________________                parts______________________________________Dye dispersion         6Tetraethylene glycol dimethyl ether                  15Water                  79                  100                  (pH: 8.0)______________________________________ 
    
     A polyester/cotton mixed cloth (mixing ratio: 65/35) was impregnated with the above prepared padding bath and squeezed at a squeezing ratio of 45% and, thereafter, it was dried at 100° C. for 2 minutes and fixed by dry heating at 200° C. for 1 minute. By washing the cloth with a hot ethanol bath, there was obtained an orange dyed product having excellent light fastness and wet color fastness. 
     The dye used in this example was prepared in accordance with the method as described in Example 13. For this dye, λ max  (acetone) was 431 nm. 
     EXAMPLE 17 
     Printing was performed in the same manner as in Example 13 except that a nylon/rayon mixed cloth (mixing ratio: 50/50) was used and the dry heating fixing temperature was 185° C. There was thus obtained a reddish yellow dyed product having good wet color fastness and light fastness. 
     EXAMPLE 18 
     Using a series of disazo dyes shown in Table 8, the same printing as described in Example 13 was performed. 
     All the dyded products had good light fastness and wet color fastness. 
     The hue of each dyed product and λ max  (acetone) of each dye used are shown in Table 8.

     The thus prepared printing color paste was printed on a polyester/cotton mixed cloth (mixing ratio: 65/35) by the use of a screen printing machine, dried at 80° C. for 3 minutes, and then fixed by dry heating at 215° C. for 90 seconds. After washing with water, the cloth was subjected to soaping using a washing solution containing 2 g/l of a nonionic surface active agent (Scourol #900 (trade name), produced by Kao Soap Co., Ltd.) at a bath ratio of 1:30 at 80° C. for 20 minutes, and there was thus obtained a yellowish red dyed product having excellent light fastness and wet color fastness. 
     The dye used in this example was prepared as follows: 
     In 50 ml of a 50% by volume aqueous solution of acetic acid was dissolved 2.13 g of 4-amino-4&#39;-hydroxyazobenzene, and 3 ml of hydrochloric acid was added thereto. Then, 0.7 g of sodium nitrite was added thereto. During this time, the temperature was regulated so as not to exceed 5° C. The thus formed diazonium salt solution was added to a solution of 2.92 g of 2,6-bis(methoxypropylamino)-3-cyano-4-methylpyridine in methanol at a temperature of 5° C. or less while maintaining the pH at 4. The disazo compound precipitated was separated by filtration, washed with water, and dried. A mixture of 5.16 g of the above prepared dye, 2.1 g of 2,4-difluoro-6-(diethylamino)triazine, 1.0 g of triethylamine, and 1.0 g of anhydrous potassium carbonate was added to 100 ml of acetone and heated to reflux to achieve a condensation reaction. The reaction solution was added dropwise to 1,000 ml of water. The precipitate formed was separated by filtration, washed with water, and dried at room temperature. There was thus obtained 6.6 g of dark red powder of dye represented by the above described formula (yield: 94%). For this dye, λ max  (acetone) was 490 nm.

     The thus prepared printing color paste was printed on a cotton broad (cotton yarn number: 40) which had been subjected to a silket processing, by the use of a screen printing machine, was subjected to intermediate drying at 80° C. for 3 minutes, and then was treated using super heated steam at 185° C. for 7 minutes. Thereafter, by applying the same washing treatment as described in Example 19, there was obtained a yellowish red dyed product having excellent light fastness and wet color fastness. 
     The dye used in this example was prepared as follows: 
     4-Amino-5-methyl-4&#39;-hydroxyazobenzene was diazonated and then coupled to 2-anilino-3-cyano-4-methyl-6-(n-butylamino)pyridine in accordance with the method as described in Example 19 to prepare a dye. By reacting the thus formed dye with 2,4-difluoro-6-di(n-propyl)aminotriazine in N-methyl-2-pyrrolidone by the use of triethylamine as an acid binding agent, there was obtained the desired dye. For this dye, λ max  (acetone) was 491 nm.
