Abstract
Provided is a near-infrared-absorbing dye increasing a visible light transmittance and having a near-infrared blocking characteristic. The near-infrared-absorbing dye has an absorption characteristic measured by dissolving the dye in dichloromethane satisfying the following requirements. ⋅In an absorption spectrum at a wavelength of 400 to 800 nm, there is a maximum absorption wavelength λin a wavelength region of 670 nm or more. ⋅The following relational expression is established between a maximum absorption constant εwith respect to light with a wavelength of 430 to 550 nm and a maximum absorption constant εwith respect to light with a wavelength of 670 nm or more, where ε/ε≥65. ⋅In a spectral transmittance curve, an average transmittance of light with a wavelength of 430 to 460 nm is 94.0% or more when a transmittance at the maximum absorption wavelength λis set to 1%.
