Abstract
Disclosed herein is a novel crosslinked polyphthalocyanine compound. The polyphthalocyanine compound has a structure in which phthalocyanine units are crosslinked to absorb wavelengths in the near-infrared range of 750 to 900 nm, thus being suitable for use as a near-infrared absorber. Further disclosed is a near-infrared absorbing ink composition comprising the polyphthalocyanine compound as a near-infrared absorber.
