preparation example 1

[0060] Take 36.1 parts of 1-aminobenzene-2-sulfonic acid-4-β-sulfonic acid (1-aminobenzene-2-sulfonicacid-4-β-sulfatoethylsulfone) dissolved in 1000 parts of ice water, add 24 parts 32% hydrochloric acid (HCl) aqueous solution was fully stirred, then 7.0 parts of sodium nitrite (sodium nitrite) aqueous solution was added, and the stirring was continued at a temperature of 0-5° C. until the diazotization was completed. Then, 23.9 parts of 2-amino-5-hydroxynaphthalene-7-sulfonic acid were added to the reaction liquid, and the reaction liquid mixture was stirred until the coupling reaction was completed. Finally, add sodium chloride (NaCl) for salting out, and take out by filtration to obtain the compound of the following formula (I-1).

Abstract

The invention provides reactive red dye composition. The composition comprises of at least one of azo reactive dyes selected as the formula (I) illustrated and with the content being of 3 to 97 weight percentage, wherein, the definitions of W, D1 and the D2 are shown in the instruction book; at least one of azo reactive dyes selected as the formula (II) illustrated and with the content being of 97 to 3 weight percentage, wherein the definitions of R, X, Z, D3 and the D4 are shown in the instruction book. The reactive red dye composition of the invention is suitable for the cellulose fiber, and not only can obtain good levelness and deep dyeing effect, but also has excellent white discharging effect.

Description

technical field [0001] The invention relates to a reactive red dye composition, especially a red dye composition suitable for discharge dyeing. Background technique [0002] So far, regarding the dyeing of fabrics, it is still impossible to obtain highly dyed deep red dyes from a single reactive dye. In order to obtain high-dyed crimson dyeing effect, it must be obtained by color mixing method. [0003] Usually, to obtain a red reactive dye composition with high dyeing depth, a reactive red dye is the main body, such as the reactive red dye of the following formula (1), and then combined with orange, yellow or other colored reactive dyes , mixed to obtain a dark red reactive dye composition. [0004] [0005] Among them, the mainland patents CN1524904, CN1730565, CN1730566, the World Patent Organization WO2000006652, WO2006024639 and the US patents US2005034252, US2005034253, etc. have all disclosed similar color mixing dye technologies.
