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.

A crosslinked polyphthalocyanine compound represented by Formula 3 below:
- wherein M1 and M2, which are the same or different from each other, are independently selected from the group consisting of nonmetals, metals, metal oxides, and metal halides;
- R1 to R16, which are the same or different from each other, are independently selected from the group consisting of a hydrogen atom, a halogen atom, a hydroxyl group, an amino group, a hydroxysulfonyl group, an aminosulfonyl group, alkyl groups, substituted C1-C20 alkyl groups, SR17 in which R17 is a substituted phenyl group or an alkyl group, SR18 in which R18 is a phenyl group substituted with a C1-C20 alkoxy group, OR19 in which R19 is a substituted phenyl group or an arylalkyl group, NHR20 in which R20 is a substituted phenyl group or an arylalkyl group, and NHR21 in which R21 is a substituted C1-C20 alkyl group and n is an integer from 1 to 20.
A near-infrared absorbing ink composition comprising, as a near-infrared absorber, a compound of Formula 3 below:
- wherein M1 and M2, which are the same or different from each other, are independently selected from the group consisting of nonmetals, metals, metal oxides, and metal halides;
- R1 to R16, which are the same or different from each other, are independently selected from the group consisting of a hydrogen atom, a halogen atom, a hydroxyl group, an amino group, a hydroxysulfonyl group, an aminosulfonyl group, alkyl groups, substituted C1-C20 alkyl groups, SR17 in which R17 is a substituted phenyl group or an alkyl group, SR18 in which R18 is a phenyl group substituted with a C1-C20 alkoxy group, OR19 in which R19 is a substituted phenyl group or an arylalkyl group, NHR20 in which R20 is a substituted phenyl group or an arylalkyl group, and NHR21 in which R21 is a substituted C1-C20 alkyl group;
- and n is an integer from 1 to 20.
