New violet colorant, XPDIA was synthesized by using Acid Red 52 to develop a high-performance image sensor. Solubility of XPDIA was more than 5 wt% in PGMEA which is the main solvent in the color filter preparation process. dEab value of XPDIA showed a very low color difference of 2.17 after thermal treatment. In solvent resistance, transmittance was not changed and dEab showed a low color difference of 1.55 before and after solvent dipping. As a result of the migration test, there was no change at all after dipping in the PGMEA transmittance spectrum. The newly synthesized violet colorant, XPDIA exhibited excellent thermal-chemical stability, and good solubility and it can be applied to image sensor color filter application. |
