Document Type and Number:
WIPO Patent Application WO/2014/030443
Kind Code:
A1
Abstract:
Provided is a near-infrared-ray absorption agent having high solubility. A near-infrared-ray absorbent composition contains a solvent and the near-infrared-ray absorption agent containing a copper-phosphoric acid ester complex resulting from reacting a compound represented by formula (1) and/or a compound represented by formula (2) with a copper salt, the concentration of the copper-phosphoric acid ester complex in the near-infrared-ray absorbent composition being 10-80 mass%. (In formulas (1) and (2), each R is an organic group having at least 3 carbon atoms. Also, in formula (2), Rs may be bonded to each other, forming a cyclic structure, in which case the total number of carbon atoms in the group containing the bonded cyclic structure is at least 3.)
