Document Type and Number:
WIPO Patent Application WO/2013/099877
Kind Code:
A1
Abstract:
The present invention relates to an infrared shielding film, which contains at least one laminated unit of a high refractive index layer and a low refractive index layer on a base material, wherein the thickness of at least one of the high refractive index layer and low refractive index layer is formed non-uniformly, and in the layer in which the thickness is formed non-uniformly, the variation (V) of the thickness expressed by Equation 1 is 1 - 50%, where σ is the standard deviation of thickness and µ is the average value for thickness. According to the present invention, an infrared shielding film can be provided in which surface area can be increased at a low cost, in which changes in color are small even if the angle of observation changes, and in which color variation is small. V[%] = (σ/µ) x 100... (Equation 1)
