Embodiment

[0366] Hereinafter, examples are cited, and the present invention is further described in detail, but the present invention is not limited by the following examples, and can be appropriately changed within the scope of the above-mentioned and following purposes, and they are also included in the technology of the present invention. in range. Unless otherwise specified, "%" and "part" in an example are mass % and a mass part.

[0367] In the following synthesis examples, the compounds were identified by mass spectrometry (LC: 1200 model manufactured by Agilent, MASS: LC / MSD model manufactured by Agilent).

Synthetic example 1

[0369] 20 parts of the compound represented by the formula (1x) and 200 parts of N-ethyl-o-toluidine (manufactured by Wako Pure Chemical Industries, Ltd.) were mixed under light-shielding conditions, and the resulting solution was stirred at 110° C. for 6 hours. After cooling the obtained reaction liquid to room temperature, this was added to the mixed liquid of 800 parts of water and 50 parts of 35 weight% hydrochloric acid, and it stirred at room temperature for 1 hour, and crystallization precipitated. The precipitated crystals were collected as suction-filtered residues and dried to obtain 24 parts of the compound represented by the formula (1-24). The yield was 80%.

Abstract

The invention provides a colorant dispersion liquid, a colored filter formed by the colorant dispersion liquid, and a display device comprising the colored filter. The colorant dispersion liquid is formed by dispersing a colorant in solvent under the action of a dispersing agent. The colorant contains xanthene dye and basically does not contain pigment. Content of the xanthene dye is 40%-100% by mass relative to total content of the colorant. The dispersing agent contains amidogen. Amine value of the dispersing agent is 0-5 mgKOH/g.

Description

technical field [0001] The present invention relates to a colorant dispersion and the like. Background technique [0002] The colored curable resin composition is used for the production of color filters used in display devices such as liquid crystal display panels, electroluminescent display devices, and plasma displays. As such a colored curable resin composition, a colored curable composition (JP2010-32999-A (Example 1)) produced by dispersing a pigment in a solvent and further mixing a xanthene dye was used. [0003] The brightness of the color filter obtained from the said colored curable resin composition is not always satisfactory. Contents of the invention [0004] The present invention includes the following inventions. [0005] [1] A colorant dispersion, characterized in that the colorant is dispersed in a solvent under the action of a dispersant, [0006] Colorants containing xanthene dyes and substantially free of pigments, [0007] The content of the xanth...
