Document Type and Number:
WIPO Patent Application WO/2024/053662
Kind Code:
A1
Abstract:
Provided are: a light absorption filter containing a resin, a specific dye, and a compound that generates a radical via irradiation with ultraviolet rays, wherein a polymer constituting the resin contains a cross-linkable group; a light absorption filter comprising a resin, a compound A that has an acid group, a compound B that forms a hydrogen bond with the acid group of the compound A and generates a radical via irradiation with ultraviolet rays, and a specific dye, wherein the compound A is contained in a side chain of a polymer that constitutes the resin; an optical filter in which these light absorption filters are used, and a method for producing said optical filter; and an organic electroluminescent display device, inorganic electroluminescent display device, and liquid crystal display device comprising this optical filter.
