<p>A near-infrared radiation absorbing film comprising a base film and a near-infrared radiation absorbing layer containing a diimonium type compound having an endthermic peak in a temperature range of 220°C or higher in the differential scanning colorimetry (DSC) at a programming rate of 10°C/min. The near-infrared radiation absorbing layer may also comprise a cyanine compound, a phthlocyanine compound, a naphthlocyanine compound or a nickel complex compound, and may further comprise a quencher compound in addition to the above. The near-infrared radiation absorbing layer exhibits excellent transmission of visible lights over a wide range of wavelength.</p> |
