Abstract:
An object of the invention is to provide an anisotropic light absorption film having both a high alignment degree and high light resistance, and a laminate provided using the anisotropic light absorption film. An anisotropic light absorption film according to the embodiment of the invention is formed from a composition having a first dichroic azo dye, a second dichroic azo dye, and a compound represented by Formula (I) or a polymer thereof, the first dichroic azo dye has a solution absorption maximum wavelength of 400 nm or greater and less than 550 nm, the second dichroic azo dye has a solution absorption maximum wavelength of 550 nm or greater and 750 nm or less, and the film has an arrangement structure of the first dichroic azo dye or an arrangement structure of the second dichroic azo dye therein.
