NEAR-INFRARED ABSORBING FILM

摘要

Disclosed is a near-infrared absorbing film which absorbs light over a wide range of near-infrared wavelengths, while being highly excellent in durability, especially in wet heat resistance and heat resistance. Specifically disclosed is a near-infrared absorbing film wherein a near-infrared absorbing layer composed of a composition mainly containing a near-infrared absorbing dye and a resin is formed on a transparent base. This near-infrared absorbing film is characterized in that the composition contains either a trifluoromethanesulfonic acid compound or a bis(trifluoromethansulfonyl)imide compound.
