Title:
COLORING COMPOSITION AND COLOR FILTER
Document Type and Number:
WIPO Patent Application WO/2019/116882
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a coloring composition such that, while containing a threne-based compound that is difficult to disperse to a high degree in glycol-based solvents which have been used in color filter production processes in recent years, the coloring composition can achieve a high degree of dispersion in a glycol-based solvent and can be used without causing unwanted effects such as curing defects in a color filter production process. The problem can be solved by providing a coloring composition that contains a specific anthraquinone derivative, a threne-based compound, and a glycol-based organic solvent.
