Document Type and Number:
WIPO Patent Application WO/2024/024889
Kind Code:
A1
Abstract:
[Problem] To provide an optical layered body having excellent adhesiveness. [Solution] This optical layered body is obtained by layering a light-absorbing anisotropic membrane, an adhesive layer, and an optical film in contact with each other in the stated order. The light-absorbing anisotropic membrane is a cured product layer obtained by curing a dichroic dye and a polymerizable liquid crystal compound in a state where the dye and the compound are aligned in the layering direction of the optical layered body. The adhesive layer includes a cured product of a cationic curing type adhesive.
