The present invention relates to a novel bisazo compound and a method for dyeing cellulose fibers using the same. It is known that dyes having a β-sulfatoethylsulfonyl group can be applied as so-called vinylsulfone type reactive dyes for dyeing textile materials.
However, dyeings made with azo-based yellow reactive dyes having a β-sulfatoethylsulfonyl group generally have low chlorine fastness, and fading due to chlorine contained in tap water is often a problem. There has been a strong demand for a yellow reactive dye with excellent strength. Yellow dyes having a monochlorotriazinyl group as another typical reactive group different from the β-sulfatoethylsulfonyl group are also known, for example, in JP-A-55-13790. Reactive dyes generally require high dyeing temperatures and lack suitability for exhaust dyeing, so they are only used for textile printing, and they also have the disadvantage of low acid stability of the dyed products obtained. Therefore, it could never be said to be sufficient for practical purposes. For this reason, the present inventors conducted extensive research in search of a yellow vinyl sulfone type reactive dye with particularly excellent chlorine fastness, and found that a so-called vinyl sulfone type reactive group and a monochlorotriazinyl It has been found that a specific bisazo compound having at the same time a monochlorotriazinyl group eliminates the disadvantages of the above-mentioned reactive dyes having only a monochlorotriazinyl group, and gives a reddish-yellow dyeing with excellent chlorine fastness, and the present invention I was able to complete it. That is, the present invention provides the following general formula () in the form of a free acid: [In the formula, R 1 is a hydrogen atom, a cyano group, a carbamoyl group, or a sulfoalkyl group, R 2 is a hydrogen atom or a sulfonic acid group, X 1 and X 2 are each a hydrogen atom,
Chlorine atom, methyl group, methoxy group, carboxyl group or sulfonic acid group, Y is -CH= CH2 or -CH2CH2Z , Z is halogen atom, -OSO3H or -OPO3H2 , n is 1 , 2, 3, or 4. ] Provided is a method for dyeing cellulose fibers, which is characterized by using a bisazo compound represented by the following and a bisazo compound represented by the above general formula (). In the present invention, the substituent represented by R 1 is:
a hydrogen atom, a sulfoalkyl group such as a cyano group, a carbamoyl group, a sulfomethyl group, a sulfoethyl group, an α-methyl or an ethylsulfomethyl group, -
(CH 2 )n- as -CH 2 -, -CH 2 CH 2 -, -
CH2CH2CH2- or -CH2CH2CH2CH2- is exemplified as a typical substituent . The bisazo compound represented by the above general formula () exhibits various dye properties, such as high exhaustion rate and fixation rate, excellent build-up property, and chlorine,
It is useful as a reactive dye that gives a reddish-yellow dyed product with excellent light fastness, perspiration and sunlight fastness, and excellent wash-off properties.

The bisazo compound represented by the general formula () of the present invention can be used to dye cellulose fibers into a dark reddish yellow color by a conventional dyeing method, such as an exhaustion method, a printing method, or a continuous dyeing method including a cold patch batch method. Can be dyed. In the present invention, the cellulose fibers include natural or regenerated cellulose fibers such as cotton, hemp, viscose human silk, and viscose cotton. In the case of the exhaust method, the dyeing of the present invention is carried out at a relatively low temperature in a dye bath containing Glauber's salt or common salt in the presence of an acid binder such as soda carbonate, tribasic sodium phosphate, or caustic soda. Dyeing can also be done by a textile printing method. For example, a color paste containing an acid binder such as bicarbonate of soda, soda carbonate, tribasic sodium phosphate, or caustic soda, urea, and a sizing agent, preferably sodium alginate, is printed on the fiber, and after intermediate drying, 100% This is done by steaming or drying at ~200°C. Dyeings obtained using the bisazo compound represented by the general formula () of the present invention have excellent chlorine fastness, light fastness, and sweat/sunlight fastness. For example, the following dyes described in the above-mentioned Japanese Patent Application Laid-open No. 55-13790 The chlorine fastness of the compound is 1st to 2nd grade according to the ISO method, but the compound of the present invention has an excellent chlorine fastness of 3rd to 4th grade. In particular, considering that the use of chlorine bleaches in household laundry has recently become widespread, the value of the bisazo compound of the present invention, which has excellent chlorine fastness, is high. In addition, its excellent light fastness, sweat fastness and sunlight fastness make it suitable for dyeing external wear such as sportswear. In addition, the bisazo compound of the present invention exhibits a high exhaustion rate and fixation rate in exhaustion dyeing, which not only makes it possible to obtain dyed products with high density, but also has excellent wash-off properties, making it easy to remove unfixed dye. It has the great advantage of being easy to do. Furthermore, the bisazo compound of the present invention has the unique ability to be hardly affected by changes in dyeing temperature, alkali agent, amount of inorganic salt added, and bath ratio in exhaust dyeing, and can be dyed with extremely high reproducibility. .

It was dried at 60°C to obtain 49.5 parts of a dye having the following structural formula. Example 2 (Compound No. 2) To a solution in which 0.1 part of a nonionic surfactant was dissolved in 100 parts of water, 9.2 parts of cyanuric chloride was added and dispersed at 0 to 10°C. A solution prepared by dissolving 10.5 parts of sodium 2,5-diaminobenzenesulfonate in 100 parts of water was added dropwise to the solution over 1 hour while maintaining the temperature at 0 to 5°C and the pH at 2 to 3, and the mixture was stirred for about 2 hours. Next, 16.9 parts of 1-aminobenzene-3-β-hydroxyethylsulfone sulfate was added, and the pH was adjusted.
The temperature was raised to 30 to 40°C while adjusting the temperature to 5 to 6, and the mixture was stirred at the same temperature for 5 hours. Next, 3.5 parts of sodium nitrite was added and dissolved.
Diazotization is carried out by injecting 13 parts of concentrated hydrochloric acid at 0 to 5°C, and then 1,2-bis(3-carbamoyl-6
-Hydroxy-4-methyl-2-pyridone-1-
) Add 9.2 parts of ethane to 100 parts of water, adjust the pH to 5 to 6 with aqueous caustic soda solution, and add the diazo solution to the solution.
Injection was performed while maintaining the pH at 5 to 6, and coupling was performed. 100 parts of sodium chloride was added to this solution to precipitate crystals, which were filtered under suction, washed, and dried at 60°C to obtain 51.8 parts of a dye having the following structural formula.

In this way, a reddish-yellow print with excellent chlorine fastness was obtained. Example 7 30 parts of dye of Compound No. 2 are dissolved in 925 parts of boiling water and cooled to room temperature (about 20°C). Then 32.5
A liquid composition is prepared by adding 15 parts of aqueous sodium hydroxide solution and 30 parts of Glauber's salt. A cellulose fabric is immersed in this liquid and squeezed using a known method to a squeezing rate of 65%. After the padded cellulose fabric is rolled up, it is sealed with polyethylene film or the like and left at room temperature (approximately 20°C) for 20 hours. The cellulose fabric is then washed with cold water, then hot water, soaped in a boiling detergent solution, washed with cold water and finished by drying. This gave a very deep reddish-yellow spotless dyeing.
