INFRARED SHIELDING FILM HAVING DIELECTRIC MULTILAYER FILM STRUCTURE

摘要

Provided is an infrared reflective film which has excellent insulating effects in the summer season and excellent heat retention effects in the winter season. Further, provided is an infrared shielding film in which the risk of heat cracks can be reduced by preventing heat generation on the film and which can be easily pasted.;An infrared shielding film having a dielectric multilayer film (A), a dielectric multilayer film (B) and a non-interference layer disposed between the dielectric multilayer film (A) and the dielectric multilayer film (B), wherein the dielectric multilayer film (A) has the maximum reflectance value, which has a reflectance of 50% or more, in the wavelength region of 900 to 1100 nm, and the dielectric multilayer film (B) has the maximum reflectance value in the wavelength region of 1200 to 2100 nm, and any one layer other than the dielectric multilayer film (A) and the dielectric multilayer film (B) contains an infrared absorber, and the surface on which the dielectric multilayer film (A) is laminated is installed to face the outdoor side.
