Abstract
Provided are a near-infrared-ray-absorbing composition having strong near-infrared shielding properties when a cured film is produced, a near-infrared-ray cut filter, a manufacturing method therefor, a camera module, and a manufacturing method therefor. The near-infrared-ray-absorbing composition includes a copper complex obtained by reacting a compound (A) having at least two coordination sites with a copper component.
Claims19
A near-infrared-ray-absorbing composition comprising:
- a copper complex obtained by reacting a compound (A) having at least two coordination sites with a copper component.
A near-infrared-ray-absorbing composition comprising:
- a copper complex obtained by reacting a compound (A1) having two monoanionic coordination sites or a compound having a salt of the compound (A1) with a copper component.
A near-infrared-ray-absorbing composition comprising:
- a copper complex including a copper as a central metal and a compound having two monoanionic coordination sites as a ligand, or a copper complex including a structure having two monoanionic coordination sites.
