Disclosed is a film or panel having excellent near- infrared absorbability or, that is, excellent near-infrared shieldability, and having a high degree of visible ray transmittance and good color tone. To produce the near-infrared-absorbing film or panel having good color tone while the near-infrared-absorbing dye to be 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 to be 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.
Cette invention concerne un film ou un panneau qui possèdent d'excellentes qualités d'absorption des rayons proches de l'infrarouge ou de protection contre ces derniers, ainsi qu'une grande perméabilité aux rayons du spectre visible et d'excellents tons de couleurs. Afin de fabriquer un film ou un panneau absorbant les rayons proches de l'infrarouge et possédant d'excellents tons de couleur, on fait appel à une résine et à un pigment absorbant les rayons proches de l'infrarouge, ainsi qu'à un procédé permettant de fabriquer ce film ou panneau tout en maintenant le pigment à l'état stable. Cette invention concerne en outre un film multicouches ou un panneau se composant de plaques multicouches, lesquels offrent des fonctions complémentaires, tel que l'absorption des ondes électromagnétiques, et sont fabriqués tout en maintenant le pigment à l'état stable.
