摘要:
To provide an infrared-shielding body sufficiently transmitting visible rays, having no half-mirror shaped appearance, requiring no large-scale apparatus when forming a film on a substrate, efficiently shutting invisible near-infrared rays with wavelength range of 780 nm or more, while eliminating a heat treatment at high temperature after film formation, and having a spectral characteristic such as transparency with no change of color tone. The starting material, which is a mixture containing a predetermined amount of a tungsten compound, is heated at 550° C. in a reductive atmosphere for 1 hour, then cooled to room temperature once in an argon atmosphere, thus producing powder of W18O49. Then, the powder, the solvent, and the dispersant are mixed, then subjected to dispersion treatment to obtain a dispersion solution. The dispersion solution and a UV-curable hardcoat resin are mixed to obtain a solution of fine particle dispersion of infrared-shielding material. The solution of the fine particle dispersion of infrared-shielding material is applied on a PET resin film to form a film, which is then cured, and an infrared-shielding film having a transmission profile shown in the figure is thereby obtained.
