Abstract

PURPOSE:To improve visible ray transmittability and heat ray shielding ability by laminating an optically selective transmittable absorbing body provided with a metallic layer consisting essentially of Ag and a thin film layer contg. a near IR absorbent having an absorption peak in a specific wavelength region on an org. polymer film. CONSTITUTION:A metallic layer A of 40-180Angstrom contg. >=50wt% Ag, an antireflection layer B formed by using a dielectric material having >=1.5 refractive index, a thin film layer C contg. a near IR absorbent having an absorption peak between 800-1,200nm wavelength, and an org. polymer film D are laminated. These layers are successively disposed in order of any among B/A/B/C/D, B/A/ C/D, B/A/B/D/C, B/A/D/C, C/B/A/B/D or C/B/A/D, so that the integrated transmittance of visible light thereof is made >=70% and the integrated transmittance of IR light <=50%. The defects among the layers are complementally overcome and the mutual advantages are synergistically improved by the above-mentioned combination, by which the optically selective transmittability is improved. Such sheet is used for the window of a building, the window of an automobile, etc.
