NEAR-INFRARED-ABSORBING COMPOSITION, NEAR-INFRARED CUT-OFF FILTER AND PRODUCTION METHOD USING SAME, AND CAMERA MODULE

摘要

Provided are a near-infrared-absorbing composition capable of forming a cured film having excellent heat resistance while maintaining high near-infrared shielding properties, a near-infrared cut-off filter, a production method using the same, and a camera module. Provided are a near-infrared-absorbing composition including a compound obtained from a reaction between a polymer (A1) having an acid group or a salt thereof and a copper component and a near-infrared-absorbing composition including a compound obtained from a reaction between a polymer (A1) having an acid group or a salt thereof and a copper component and a copper complex obtained from a reaction between a low-molecular-weight compound having a coordination site and a copper component.
