Abstract
In a film or panel having excellent near-infrared absorbability and excellent near-infrared shieldability, and having a high degree of visible ray transmittance and good color tone, in order to produce the near-infrared-absorbing film or panel having good color tone while the near-infrared-absorbing dye disposed therein is kept stable, the dye and the binder resin for the dye are specifically selected, and the production method is also specifically selected. In addition, for the purpose of producing the film or panel while the dye disposed therein is kept stable and for the purpose of making the film or panel have additional functions such as electromagnetic radiation absorbability, the film or panel is made to have a multi-layered structure.
