Title:
NEAR−INFRARED RADIATION ABSORBING FILM
Document Type and Number:
WIPO Patent Application WO/2003/032028
Kind Code:
A1
Abstract:
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&sol 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.
