Embodiment

[0538] The following examples are enumerated and the present invention is further specifically described, but the present invention is not limited to the following examples, and it can also be implemented by suitably changing within the scope of the aforementioned and later-mentioned gist, and these are all included in the technical scope of the present invention Inside. Unless otherwise stated, "%" and "part" in an example are mass % and a mass part. 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

[0540] 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 at room temperature, it was added to a liquid mixture of 800 parts of water and 50 parts of 35% hydrochloric acid, and stirred at room temperature for 1 hour to precipitate crystals. The precipitated crystal was taken out as the residue of suction filtration and dried to obtain 24 parts of the compound represented by the formula (1-24). The yield is 80%.

Abstract

The invention provides a colorant dispersion liquid which is a colorant dispersion liquid that is formed by dispersing a colorant in a solvent, wherein the colorant contains dyes and pigments; the solvent contains propylene glycol methyl ether acetate; and, with respect to the total amount of the solvent, the content of the propylene glycol methyl ether acetate takes account for 40 mass% to 99 mass%.

Description

technical field [0001] The present invention relates to a colorant dispersion and the like. Background technique [0002] The colored curable composition is used at the time of manufacture of the color filter used for display devices, such as a liquid crystal display device, an electroluminescent display device, and a plasma display. And, when producing such a colored curable composition, a dispersion liquid obtained by dispersing a dye having a xanthene skeleton (xanthene dye) and a pigment in propylene glycol monomethyl ether acetate (refer to JP2011- 38085-A Example 1). [0003] The colored curable composition manufactured from the said dispersion liquid does not necessarily fully satisfy the storage stability. Contents of the invention [0004] The present invention includes the following technical solutions. [0005] [1] A colorant dispersion liquid in which a colorant is dispersed in a solvent, wherein, [0006] Colorants contain dyes and pigments, [0007] The ...
