Infrared shielding film
Abstract:
An infrared shielding film has at least one unit on a substrate, the unit having a low refractive index layer that contains first metal oxide particles and a first binder and a high refractive index layer that is arranged adjacent to the low refractive index layer, contains second metal oxide particles and a second binder, and has a higher refractive index than the low refractive index layer, in which at least one layer of the low refractive index layer and the high refractive index layer contains, as a binder, at least one of the following (a) to (c): (a) a carboxyvinyl polymer that contains a monomer component, which contains a carboxylic acid, in an amount of 20 to 75% by mass of the entire composition, (b) a copolymer having pH dependency of viscosity, and (c) a modified polyvinyl alcohol.
