TRANSPARENT LAMINATE FILM AND METHOD FOR PRODUCING SAME

摘要

Disclosed is a transparent laminate film which has visible light transmittance, sunlight blocking properties, radio wave transmittance and good appearance at the same time. Specifically disclosed is a transparent laminate film which has, on at least one surface of a transparent polymer film, a laminated structure in which a metal oxide layer containing an organic content and a metal layer are laminated. The laminated structure is provided with grooves each having a width of not more than 30 µm. The transparent laminate film as a whole has a surface resistivity of not less than 150 O/?. The grooves are preferably composed of numerous cracks that are present in the laminated structure, or formed by laser processing. It is also preferable that the transparent polymer film has a highly adhesive layer on at least one surface, and the laminated structure is formed on the highly adhesive layer. The metal oxide layer containing an organic content is preferably formed by a sol-gel method wherein optical energy is used during the sol-gel curing.
