New dyes based on anthraquinone derivatives for color filter colorants.

Two new compounds which substituted quinoline group in 1,4-position and 1,8-position of anthraquinone were synthesized for color filter. The change in physical properties according to the substituted position of the synthesized compound was systematically identified from the perspectives of optical property and thermal property. The extinction coefficient (ε) of the synthesized substance has a very high value more than 4.26 in log scale. Td value is more than 300 °C, which shows high thermal stability. This showed quite excellent results in optical property and thermal stability.
