Abstract
Provided is a near-infrared absorptive compositions capable of reducing unevenness in the coated surface profile and variation in near-infrared absorptive ability when the near-infrared absorptive compositions are formed into films. The near-infrared absorptive composition comprises a copper complex and a solvent, wherein the near-infrared absorptive composition has a solid content of 10 to 90% by mass and the solvent has a boiling point of 90 to 200° C.
