OPTICAL REFLECTION FILM, INFRARED SHIELDING FILM, AND PROCESS FOR PRODUCING THE SAME

摘要

To provide an optical reflection film which has high reflectance of light with desired wavelength and reduced haze, by controlling the level of interlayer mingling to suppress the disturbances of the interface, even when the optical reflection film is produced by multilayer coating, in particular, by simultaneous multilayer coating which allows a high production efficiency.;Provided is an optical reflection film which has a base and, formed thereon, at least one unit obtained by laminating a high refractive index layer and a low refractive index layer, in which the low refractive index layer contains silica particles onto which a silanol-modified polyvinyl alcohol has been adsorbed.
