Title:
OPTICAL FILTER, AND HEAT RAY SHIELDING MATERIAL
Document Type and Number:
Japanese Patent JP2014044341
Kind Code:
A
Abstract:
To provide an optical filter in which transmissivity at the maximal reflectance wavelength is low, a warming rate (a ratio of an absorptance to a reflectance at the maximal reflectance wavelength) is low, and planar properties are good.
An optical filter comprises a support and a pigment-containing layer containing at least one kind of pigment, has a maximal reflectance of 20% or more, and the pigment contained in the pigment-containing layer is 190 mg/m2 or less.
