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.
Claims12
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, wherein the compound (A) is a compound (A3) having three or more coordinating atoms to be coordinated with an unshared electron pair and the coordinating atoms are nitrogen atoms;
- and wherein the composition further comprises a curable compound which contains at least one of a trifunctional or higher acrylate and a trifunctional or higher methacrylate, and a trifunctional or higher epoxy resin.
A near-infrared-ray-absorbing composition comprising:
- a curable compound, a solvent, and a copper complex obtained by reacting a compound (A) having at least two coordination sites with a copper component, wherein the compound (A) is a compound (A3) having three or more coordinating atoms to be coordinated with an unshared electron pair and the coordinating atoms are nitrogen atoms,
- wherein the curable compound is at least one of a trifunctional or higher acrylate, a trifunctional or higher methacrylate, and a trifunctional or higher epoxy resin.
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, wherein the compound (A) is a compound (A3) having three or more coordinating atoms to be coordinated with an unshared electron pair and the coordinating atoms are nitrogen atoms, and wherein the near-infrared-ray-absorbing composition further comprises a curable compound which contains a compound having a trifunctional or higher epoxy group or an oxetanyl group.
