Embodiment 1

[0060] 51.8 g of the compound of formula 15 shown below was dissolved in 500 g of water, and 100 g of ice was added to the resulting solution, thereby cooling the solution. 19.0 g of cyanuric chloride was added to the solution, and the mixture was stirred and reacted at 5° C. and pH 5 for 2 hours. Then, 22.5 g of 2-aminoethyl-2'-sulfatoethylsulfone was added, and condensation was carried out at 30° C. and pH 7.5. To the resulting solution was added 31.0 g of 3-sulfatoethylsulfone-1-aminobenzene, and the reaction was completed at 70°C and pH 2.5. The reaction solution was filtered to remove insoluble matter, and then salted out using 150 g of sodium chloride. The obtained crystals were dried to obtain 92.5 g of the compound of formula 16 as shown below:

Embodiment 2

[0063] 51.8 g of the compound of formula 15 was dissolved in 500 g of water, and 100 g of ice was added to the resulting solution, thereby cooling the solution. 19.0 g of cyanuric chloride was added to the solution, and the mixture was stirred at 5° C. and pH 5 for 2 hours to complete the reaction. Then, 22.5 g of 2-aminoethyl-2'-sulfatoethylsulfone was added, and condensation was carried out at 30° C. and pH 7.5. To the resulting solution was added 9.0 g of morpholine, and the reaction was completed at 80°C and pH 9. The reaction solution was filtered to remove insoluble matter, and then salted out using 130 g of sodium chloride. The obtained crystals were dried to obtain 81.5 g of the compound of formula 17 as shown below:

[0064]

Embodiment 3

[0066] 43.8 g of the compound of formula 18 shown below was dissolved in 500 g of water, and 100 g of ice was added to the resulting solution, thereby cooling the solution. 19.0 g of cyanuric chloride was added to the solution, and the mixture was stirred at 5° C. and pH 5 for 2 hours to complete the reaction. Then, 31.3 g of 2-(N-ethylamino)ethyl-2'-sulfatoethylsulfone was added, and condensation was performed at 25°C and pH 7.5, thereby completing the reaction. The reaction solution was filtered to remove insoluble matter, and salted out using 130 g of sodium chloride. The obtained crystals were dried to obtain 83.5 g of the compound of formula 19 as shown below:

Abstract

Provided is a reactive dye composition, comprising (i) a reactive red dye represented by Formula 1; (ii) one or more reactive dyes selected from the group consisting of a reactive yellow dye represented by Formula 2, a reactive orange dye represented by Formula 3 and a mixture thereof; and (iii) one or more reactive dyes selected from the group consisting of a reactive blue dye represented by Formula 4, a reactive blue dye represented by Formula 5 and a mixture thereof; and a method of dyeing a fiber material containing nitrogen or hydroxyl group using the same. Therefore, it is possible to provide fiber products having superior light fastness and combined colors.

Description

technical field [0001] The present invention relates to novel reactive dye compositions with triple color matching. Background technique [0002] As a conventional process for three-color dyeing using reactive dyes, there is known a color-blocking method using a red dye such as C.I. Reactive Red 195 or C.I. Reactive Red 180 with yellow and blue dyes. In this case, the yellow and blue dyes exhibited excellent light fastness, but the red dye had problems related to exhibiting physical properties required in dyeing. Recently, in coloring materials using reactive dyes, as users' demands for light fastness have increased, the use of conventional reactive red dyes has not been able to keep up with these demands. Likewise, there is a need for the development of red dyes with high light fastness. [0003] -C.I. Reactive Red 195: [0004] [0005] -C.I. Reactive Red 180: [0006] Contents of the invention [0007] Thus, the present invention has been accomplished in order...
