 This embodiment provides a kind of emerald green reactive dye compound with high sun exposure, which is specifically prepared by the following method:
 (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;
 (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...
 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).
 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.
