Problems solved by technology

At present, green dyes are mostly prepared by compounding two or three kinds of dyes, but due to the differences in the solubility of compound dyes, directness to fibers during dyeing, reactivity to alkali fixation and other performance differences, resulting in poor dyeing stability, Easy to dye flowers, large color difference between front and back
For example, reactive blue phthalocyanine structure dyes, whose molecules are composed of four isoindoles and form complexes with copper, have good coplanarity, but due to their large molecular weight, their diffusion properties in fibers are poor. Problems such as poor compatibility often occur when color matching with yellow dyes (Reference: Yang Xiaohong. Compatibility performance of reactive turquoise blue and reactive yellow dyeing[J]. Printing and Dyeing, 2007,33(14):18-21.)

Embodiment 1

[0024] This embodiment provides a kind of emerald green reactive dye compound with high sun exposure, which is specifically prepared by the following method:

[0025] (a) Chlorosulfonation reaction: at 40°C, slowly (within half an hour) add 0.100mol of copper phthalocyanine powder to 220mL of chlorosulfonic acid, stir for 30min, then raise the temperature to 135-140°C, maintain the reaction for 3h; cool down to 80°C, and dropwise added 0.504mol thionyl chloride within 2h, then raised the temperature to 90°C, and kept the temperature for 2h; after the reaction was completed, it was lowered to room temperature, poured into ice water while stirring, and precipitated; stood still, filtered, The filter cake was washed with ice water until neutral to obtain the copper phthalocyaninesulfonyl chloride filter cake, which was set aside;

[0026] (b) Primary condensation reaction: 0.101mol cyanuric chloride and 60g crushed ice were beaten for 30 minutes at 0°C; 0.100mol 2,4-diaminobenzen...

Embodiment 2

[0032] This example provides a high-sun emerald green reactive dye compound, the specific preparation method of which is similar to that of Example 1. The difference is: N-methyl-3-formamido-4-methyl-6-hydroxyl-2-pyridone in step (d) is replaced by N-ethyl-3-formamido-4-methyl -6-hydroxyl-2-pyridone, consumption is 0.100mol; Through step (f), finally obtain a kind of emerald green reactive dye compound containing copper phthalocyanine and pyridone double color body, structure such as the formula in table 1 (I-2A).

Embodiment 3

[0034] This example provides a high-sun emerald green reactive dye compound, the specific preparation method of which is similar to that of Example 1. The difference is: N-methyl-3-formamido-4-methyl-6-hydroxyl-2-pyridone in step (d) is replaced by 1-(4'-sulfonic acid phenyl)-3- Methyl-5-pyrazolone, consumption is 0.100mol, is dissolved in 150mL water, and with 20% sodium carbonate solution adjustment pH value is 7~8, and pH value is maintained at 7~8 in the reaction process; Through step (f) , and finally obtain an emerald green reactive dye compound containing copper phthalocyanine and pyrazolone dichromate, the structure of which is shown in the formula (I-3A) in Table 1.

Abstract

The invention provides a high-light-fastness emerald reactive dye compound, which has the following general structural formula (I), a+b+c=3.5, wherein CuPc, X, R1, R2 and R3 are as defined in the specification. The high-light-fastness emerald reactive dye compound can directly realize intramolecular color matching through yellow and blue double-chromophore in molecules, thus thoroughly solving a series of problems during dye compounding. In addition, the emerald reactive dye compound has excellent light fastness and good application effect, and has a good development prospect in clothing and / or other textile, especially in curtain and auto interior materials.

Description

technical field [0001] The invention relates to a reactive dye compound, in particular to an intramolecular color-matched dichroic high-sun emerald green reactive dye compound containing yellow and blue. Background technique [0002] Reactive dyes have the characteristics of bright color, complete chromatogram, and excellent wet fastness, and are widely used in the dyeing and printing of cellulose fibers and protein fibers. With the improvement of people's living standards, the requirements for the styles and colors of textiles are getting higher and higher. At present, green dyes are mostly prepared by compounding two or three kinds of dyes, but due to the differences in the solubility of compound dyes, directness to fibers during dyeing, reactivity to alkali fixation and other performance differences, resulting in poor dyeing stability, Easy to dye flowers, large color difference between front and back. For example, reactive blue phthalocyanine structure dyes, whose mole...
