Abstract:
The near infrared absorbing composition includes: a copper-containing polymer having a copper complex site at a polymer side chain; and a solvent, in which the copper complex site includes a site multidentate-coordinated to a copper atom and at least one selected from the group consisting of a site monodentate-coordinated to a copper atom and a counter ion to a copper complex skeleton, and a polymer main chain and a copper atom at the copper complex site are bonded to each other through the site monodentate-coordinated to a copper atom or the counter ion.
