AB  - A new dimeric triarylmethine-based dye, Ac-BTM-DHFMS, substituted with methacrylate groups, was designed and synthesized to improve thermal and chemical stability by using polymerisation of the acrylate cross-linking group. To evaluate the dye in color filter applications, filters were fabricated and evaluated after heat treatment at 230 °C for 1 h, and solvent stability was evaluated after dipping filters for 10 min in isopropyl alcohol (IPA), propylene glycol monomethyl ether acetate (PGMEA), and cyclohexanone. During the thermal stability test, Ac-BTM-DHFMS showed a ΔEab value of 4.21. In the solvent stability test, Ac-BTM-DHFMS showed ΔEab values of 1.0 (IPA), 0.3 (PGMEA), and 0.7 (cyclohexanone), respectively. These ΔEab values of color filter mean that Ac-BTM-DHFMS is thermally and chemically more stable than H-BTM-DHFMS without the methacrylate groups. These results show that Ac-BTM-DHFMS has potential for application as a color filter for blue dyes.
