    • The present invention aims to provide a near-infrared absorption film having excellent near-infrared blocking properties and visible light transparency over a wide wavelength range, and attractive appearance. It further aims to provide a near-infrared absorption film having excellent near-infrared blocking properties, visible light transparency, good appearance and excellent durability such as anti-deterioration properties. The film may comprise a transparent substrate, and a near-infrared absorption layer containing a cyanine compound represented by the formula (1), and a diimonium compound. wherein, in the formula (1), A is a divalent bonding group comprising ethylene. R1 and R2 are monovalent groups comprising a carbon atom. X− is a monovalent anion. The film may also comprise a transparent substrate, and a near-infrared absorption layer containing a layer containing the cyanine compound represented by the formula (1) and a layer containing a diimonium compound.
    • 本发明的目的在于提供一种在宽波长范围内具有优异的近红外阻挡性和可见光透明性的近红外吸收膜,外观美观。 本发明的目的还在于提供一种具有优异的近红外阻隔性,可见光透明性,良好的外观以及耐劣化性等优异的耐久性的近红外吸收膜。 膜可以包括透明基材和含有由式(1)表示的花青化合物的近红外吸收层和二亚铵化合物。 其中,在式(1)中,A是包含乙烯的二价键合基​​团。 R 1和R 2是包含碳原子的一价基团。 X - 是一价阴离子。 该膜还可以包括透明基底和含有含有由式(1)表示的花青化合物的层和含有二亚铵化合物的层的近红外吸收层。
