Abstract
The present invention relates to UV-blocking films for architectural and automotive use that provide 100% UV and blue light blocking. UV-blocking films according to the present invention consist of a transparent base layer and a UV-blocking layer formed on the transparent base layer using a sputtering method. The UV-blocking layer includes one or more oxides selected from a group consisting of zinc, titanium, zirconium, cesium, and silicon, with a wavelength transmission rate of 0% or less in the range of 280-400 nm.
