A near-infrared absorbing film comprising a transparent substrate film and, superimposed thereon, a near-infrared absorbing layer of composition containing a resin and a near-infrared absorbing dye that has the maximum absorption at a wavelength of 800 to 1200 nm, characterized in that 0.01 to 2.0 mass% of surfactant of 2 to 12 HLB is contained in the composition. The thus provided near-infrared absorbing film has wide absorptive power in the near-infrared region, exhibiting high light transmittance in the visible light region, and exhibits less change of optical characteristics over time. Further, the thus provided near-infrared absorbing film is one excelling in coating film appearance that can meet recent-year requirements for high luminance of display as well as high fineness and high image quality in hi-vision broadcasting. |
