INFRARED RAY SHIELDING FILM

摘要

An infrared ray shielding film having a metal particle-containing layer in which hexagonal to circular tabular metal particles are contained in 60% by number or more relative to total number of the metal particles contained in the metal particle-containing layer exhibits excellent infrared ray reflection at a wide range of from 800 nm to 2000 nm and shows little heat ray absorption.

主权项

1. An infrared ray shielding film having a metal particle-containing layer that contains at least one kind of metal particle, wherein:
hexagonal to circular tabular metal particles are contained in 60% by number or more relative to total number of the metal particles contained in the metal particle-containing layer, and at least one of the metal particle-containing layers has at least two absorption peaks or at least two reflection peaks in a region of 800 nm to 2000 nm.
