The present specification relates to a method for preparing a colorant composition comprising dissolving a first xanthene-based dye having the same number of positive charges and negative charges and a second xanthene-based dye having more negative charges than positive charges by one or more in a first solvent; and precipitating the dissolved first xanthene-based dye and the dissolved second xanthene-based dye in a second solvent, and a colorant composition, a colorant dispersion, a photosensitive resin composition, a color filter and a liquid crystal display device.

Glucose-sensing luminescent dyes, polymers, and sensors are provided. Additionally, systems including the sensors and methods of using these sensors and systems are provided.

Disclosed is a color material dispersion liquid for a color filter, the dispersion liquid being capable of forming a high-luminance coating film with excellent light resistance; a color resin composition for a color filter, the composition being capable of forming a high-luminance coating film with excellent light resistance; a color material that has, while it can form a high-luminance coating film, excellent light resistance; a high-contrast, high-luminance color filter; a liquid crystal display device including the color filter; and a light-emitting display device including the color filter. The color material dispersion liquid for a color filter, includes: (A) a color material, (B) a dispersant and (C) a solvent, wherein the color material (A) contains a cerium lake color material of an acid dye.
