Title:
COPPER PHTHALOCYANINE COMPOUNDS AND NEAR-INFRARED ABSORPTION FILTER USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2010/076969
Kind Code:
A2
Abstract:
Disclosed are novel copper phthalocyanine compounds with low absorption efficiency in the visible light domain and high absorption efficiency in the near-infrared light domain, and a near-infrared absorption filter using the same. The near-infrared absorption copper phthalocyanine compounds have chemical formula 1. In the chemical formula 1: A2, A3, A6, A7, A10, A11, A14, and A15 individually represent OR1, SR2, or a halogen atom, wherein at least four thereof represent OR1; A1, A4, A5, A8, A9, A12, A13, and A16 individually represent OR1, SR2, NR3R4,or a halogen atom, wherein at least two thereof represent NR3R4 andat least four thereof represent OR1; R1, R2, R3 and R4 individually represent an alkyl group with 1-10 carbons, an aryl group with 6-10 carbons, or an aralkyl group with 7-15 carbons.
