PHOTO-ALIGNMENT POLYMER, BINDER COMPOSITION, BINDER LAYER, OPTICAL LAMINATE, METHOD FOR MANUFACTURING OPTICAL LAMINATE, AND IMAGE DISPLAY DEVICE

WIPO Patent Application WO/2021/241450

A1

The present invention addresses the problem of providing: a photo-alignment polymer capable of improving the liquid crystal orientation properties of an optical anisotropic layer provided in the upper layer thereof; a binder composition; a binder layer; an optical laminate; a method for manufacturing an optical laminate; and an image display device. This photo-alignment polymer has: a repeating unit A including a photo-aligned group; and a repeating unit D including a cleaving group that decomposes as a result of the action of at least one type selected from the group consisting of light, heat, acids and bases and creates a cross-linking group. The cross-linking group is a self-cross-linking group or is a cross-linking group that reacts with a hydroxyl group, an amino group, a carboxy group, or an amide group and forms a chemical bond. The repeating unit D has the cleaving group on a side chain thereof and has a fluorine atom or a silicon atom further on the terminal side of the side chain than the cleaving group.
