Title (EN) TWO COMPONENT INFRARED REFLECTING FILM
(FR) FEUIL A DEUX COMPOSANTS REFLECHISSANT L'INFRAROUGE
Abstract: front page image
(EN)The present invention provides a two-component infrared reflecting film which reflects light in the infrared region of the spectrum while suppressing second, third and fourth order reflections in the visible spectrum. The film comprises alternating layers of first (A) and second (B) diverse polymeric materials having a six layer alternating repeat unit with relative optical thicknesses of .778A.111B.111A.778B.111A.111B. The polymeric materials differ from each other in refractive index by at least 0.03.
(FR)Feuil à deux composants réfléchissant la région du spectre lumineux correspondant à l'infrarouge, tout en supprimant les réflexions des deuxième, troisième et quatrième ordre du spectre visible. Ce feuil comporte 6 couches alternées (A) et (B) de deux polymères différents dont les épaisseurs optiques respectives sont de .778A.111B.111A.778B.111A.111B. Les indices de réfraction des deux polymères diffèrent d'au moins 0,03.
