Title:
OPTICAL FILTER AND HOT-WIRE SHIELDING MATERIAL
Document Type and Number:
WIPO Patent Application WO/2014/034518
Kind Code:
A1
Abstract:
This optical filter comprises a support and a pigment-containing layer containing at least one type of pigment, has a maximum reflectance of at least 20%, and the pigment contained in the pigment-containing layer does not exceed 190mg/m2. Transmissivity at the maximum reflectance wavelength is low, warming rate (ratio of absorption to reflection at the maximum reflectance wavelength) is low, and planar properties are good.
