[0033] A method for synthesizing a blue colorant complex polymer red dye for color photoresist, comprising the following steps:
[0034] 1) Acidification: add acid red 52 dye to the first reaction kettle, add an appropriate amount of water to dissolve, stir and dissolve for 20-40min, then dropwise add hydrochloric acid to carry out acidification reaction, evaporate and filter to obtain acidified dye after the reaction is completed;
[0035] 2) Acyl chloride reaction: continue to add acidified dye to the second reaction kettle, then add an appropriate amount of solvent, heat up to 30-40 degrees Celsius, stir for 20-40min, then add acyl chloride reagent, heat up to the system solution reflux, the temperature is 80~200℃, temperature controlled reaction for 6~20h, after the reaction is over, the solvent is distilled off under reduced pressure, and then the first step intermediate is obtained;
[0036] 3) Synthesis reaction: the first step intermediate obtained in the above steps i...

[0055] 1) acidification: add 1mol of acid red 52 dye in the first reaction kettle, add an appropriate amount of water to dissolve, stir and dissolve for 20min, then dropwise add 1mol of hydrochloric acid to carry out acidification reaction, evaporate and filter to obtain acidified dye after the reaction is completed;
[0056] 2) acyl chloride reaction: continue to add 1mol of acidified dye to the second reactor, then add an appropriate amount of solvent, be warming up to 30 degrees Celsius, stir for 20min, then add 1mol of acid chloride reagent, be warming up to the reflux of the system solution, the temperature is 80 ℃, temperature controlled reaction for 6h, after the reaction, the solvent was distilled off under reduced pressure, and then the first step intermediate was obtained;
[0057] 3) Synthesis reaction: the first step intermediate obtained in the above steps is added to the third reaction kettle, then an appropriate amount of solvent is added to the third reaction ke...
Embodiment 2
[0062] 1) Acidification: add 1mol of acid red 52 dye in the first reaction kettle, add an appropriate amount of water to dissolve, stir and dissolve for 40min, then dropwise add 1.5mol of hydrochloric acid to carry out acidification reaction, evaporate and filter to obtain acidified dye after the reaction is completed;
[0063] 2) acyl chloride reaction: continue to add 1mol of acidified dye to the second reactor, then add an appropriate amount of solvent, be warming up to 40 degrees Celsius, stir for 40min, then add 1.5mol of acid chloride reagent, be warming up to system solution reflux, temperature At 200°C, the temperature-controlled reaction was performed for 20h. After the reaction, the solvent was distilled off under reduced pressure to obtain the first-step intermediate;
[0064] 3) Synthesis reaction: the first step intermediate obtained in the above steps was added to the third reaction kettle, then an appropriate amount of solvent was added to the third reaction kett...
