    • A near-infrared shield according to the present invention includes a base and a near-infrared absorption layer disposed on one main surface of the base. When the near-infrared shield is irradiated from the near-infrared absorption layer side with xenon light having a wavelength of 380 nm to 1200 nm at an illuminance of 60 W/m2 (an energy density in a range of 300 nm to 400 nm) for 16 hours under a condition of BPT of 63° C. and a relative humidity of 50%, chromaticity changes Δx, Δy of transmitted light, which are shown in a chromaticity diagram of a CIE1931XYZ color system, are 0.005 or less respectively. The near-infrared shield has an excellent near-infrared shielding property and an excellent light resistance, and its near-infrared absorptivity does not deteriorate even after long-term storage.
    • 根据本发明的近红外屏蔽包括设置在基座的一个主表面上的基座和近红外线吸收层。 当以60W / m 2的照度(能量密度为300nm〜400nm)的波长为380nm〜1200nm的氙光从近红外线吸收层侧照射近红外线屏蔽时, 在BPT为63℃,相对湿度为50%的条件下,在CIE1931XYZ色系的色度图中示出的色度变化Δttax,透射光的Deltay分别为0.005以下,16小时。 近红外线屏蔽具有优异的近红外屏蔽性和优异的耐光性,并且其近红外吸收性即使在长期储存后也不会劣化。
