<p>[Problem] To provide: a near-infrared reflection film which has excellent near-infrared reflection properties and high transmissivity in a visible light region and does not undergo the unevenness of visible light reflection ratios; and a near-infrared reflection body which is equipped with the film. [Solution] A near-infrared reflection film involves, on a base, at least two high-refractive-index layers each of which comprises a water-soluble polymer and metal oxide particles each having a higher refractive index than that of the water-soluble polymer and at least two low-refractive-index layers each of which comprises a water-soluble polymer and metal oxide particles each having a lower refractive index than that of the water-soluble polymer, wherein the high-refractive-index layers and the low-refractive-index layers are laminated alternately, and wherein the film is characterized in that the thickness ratio (ˆ‘d1/ˆ‘d2) is 1.05 to 1.80 inclusive wherein n represents the total number of the high-refractive index layers and the low-refractive index layers, ˆ‘d1 represents the total thickness of the constituent layers lying between the n/2 region and the base, and ˆ‘d2 represents the total thickness of the constituent layers lying between the n/2 region and the outermost layer.</p> |
