Abstract:
A novel copper phthalocyanine compound with low absorptivity in the visible light region and high absorptivity in the near-infrared light region, and a near-infrared absorption filter using the same are disclosed. The near-infrared absorption copper phthalocyanine compound is represented by the following Formula 1, wherein, A2, A3, A6, A7, A10, A11, A14 and A15 are independently OR1, SR2 or a halogen atom, wherein at least four thereof are OR1; A1, A4, A5, A8, A9, A12, A13 and A16 are independently OR1, SR2, NR3R4 or a halogen atom, wherein at least two thereof are NR3R4, and at least four thereof are OR1; R1, R2, R3 and R4 are independently an alkyl group of 1 to 10 carbon atoms, an aryl group of 6 to 10 carbon atoms, or an aralkyl group of 7 to 15 carbon atoms.
