<p><P>PROBLEM TO BE SOLVED: To provide a near-infrared reflection film using aqueous refractive index-forming coating liquid, produced at a low cost, allowing the enlargement of an area, having superior film flexibility, a high visible light transmittance, a superior near-infrared reflection property, and superior durability, and to provide a manufacturing method thereof and a near-infrared reflection body including the near-infrared reflection film. <P>SOLUTION: The near-infrared reflection film includes at least one unit constituted of a high refractive index layer and a low refractive index layer on a base material, and a difference in refractive indices between the high refractive index layer and the low refractive index layer is 0.1 or more. At least one layer of the high refractive index layer and the low refractive index layer includes metal oxide particles, gelatin or collagen peptide, and acid or salt thereof, and the film surface pH of the unit is equal to or more than 4.0 and equal to or less than 6.0. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
