Document Type and Number:
WIPO Patent Application WO/2015/056752
Kind Code:
A1
Abstract:
[Problem] To provide a means that can reduce the angle dependence of the color of an IR-blocking film provided with a multilayer dielectric. [Solution] An IR-blocking film containing a substrate and a multilayer dielectric located on at least one surface of said substrate, said multilayer dielectric(s) comprising alternating high-refractive-index layers and low-refractive-index layers laminated together. In the L*a*b* color space, said IR-blocking film has an L* value that satisfies the relation L* < 90, an a* value that satisfies the relation −10 ≤ a* ≤ 10, and a b* value that satisfies the relation b* <−4.
