Patent ID: 7132465

Claim:
A near-infrared absorbing coat film comprising a near-infrared absorbing dye having a maximum absorption wavelength of 780 nm to 1200 nm, which has a residual near-infrared absorbing capacity of not less than 50% after 48 hours of light irradiation in en accelerated weathering test using a UV Auto Fade Meter, wherein said near-infrared absorbing coat film is formed out of a near-infrared absorbing resin composition comprising a polymer resulting from polymerization of a monomer component containing not less than 30% by mass of a monomer represented by the following general formula (1): CH 2 ═C(R 4 )—CO—OZ (1) in the formula, R 4 represents a hydrogen atom or a methyl group and Z represents a hydrocarbon group containing 4 to 25 carbon atoms, and the polymer has a number average molecular weight 1,000 to 100,000.
