Claims12
An optical article configured to color plane-polarized light transmitted through the optical article, the optical article having a color A and comprising:
- an optical article base material;
- a polarizing layer having a first color tint of color B;
- and
- a second color tint of color C, wherein
- a hue h2perp of perpendicularly polarized light transmitted through the optical article is in the blue range:
- a lightness L2 in response to perpendicularly-polarized light transmitted through the optical article is greater than 20, and
- the product L2*ΔT %[515-580nm] is greater than 200, where ΔT %[515-580nm] is a parameter describing the transmittance of randomly polarized light in the green-yellow range.
