TRANSPARENT LAMINATED FILM AND METHOD FOR MANUFACTURING TRANSPARENT LAMINATED FILM

摘要

Provided is a transparent laminated film having an excellent sunlight shielding performance and radio wave transmittance. Also provided is a method for manufacturing the transparent laminated film. This invention has a laminated structure part (16) on which a metal oxide layer (22) and a metal layer (24) are laminated on the surface of a transparent polymer film (12). A low-softening-temperature polymer layer (18) having a softening temperature of 40 to 120°C is disposed between the transparent polymer film (12) and the laminated structure part (16). A groove part (20) dividing the metal layer (24) is formed in the laminated structure part (16). The metal oxide layer (22) is formed by sol-gel hardening of a metal oxide precursor. Stress generated in the metal oxide layer (22) by sol-gel hardening is released by causing the polymer in the polymer layer (18) to soften. The groove part (20) dividing the metal layer (24) of the laminated structure part (16) is thereby formed.
