preparation example Construction

[0034] The method for producing a colored curable composition according to the present invention includes a process of preparing a dye solution by dissolving at least one dye in an organic solvent, a process of preparing a pigment dispersion liquid by dispersing at least one pigment using a dispersant, and The process of mixing a dye solution with a pigment dispersion.

[0035]

[0036] First, a process of dissolving at least one dye in an organic solvent to form a dye solution is described.

[0037] The dye used in the present invention is not particularly limited, and known dyes that have been used for color filters can be used. Examples thereof include dyes described in JP-A No. 64-90403, JP-A No. 64-91102, JP-A No. 1-94301, JP-A No. 6-11614, Japanese Patent No. 2592207, U.S. Patent No. 4,808,501, U.S. Patent No. 5,667,920, U.S. Patent No. 5,059,500, JP-A No. 5-333207, JP-A No. 6-35183, JP-A No. 6-51115, JP-A No. 6-194828, JP-A No. 8 -211599, JP-A No. 4-249549, JP-A No....

Embodiment 1

[0391] (1) Preparation of dye solution

[0392] 0.183 parts of the specific complex (Exemplary Compound Ia-3 given above) was added to 1.133 parts of cyclohexanone, and the resulting mixture was stirred at normal temperature for 60 minutes using a mixing rotor (manufactured by AS ONE Corporation), A dye solution is obtained as a result.

[0393] (2) Preparation of pigment dispersion

[0394] First, Pigment Blue 15:6 (HELIOGEN L6700F (trade name) manufactured by BASF Corporation) was refined as follows.

[0395] In detail, ingredients of the following composition were put into a double-arm kneader, and kneaded at 80° C. for 30 hours. After that, the obtained mixture was added to 100 parts of a 1% aqueous hydrochloric acid solution having a temperature of 80° C., and stirred for 1 hour. Thereafter, the resulting product was filtered, washed with hot water, dried, and pulverized, as a result of which a fine pigment of Pigment Blue 15:6 was obtained.

Embodiment 2 to 8 and comparative example 2 to 8

[0446] In addition to changing the type of dye and the type and composition ratio of organic solvents as shown in Table 1, and changing the amount of solvent to give the solid content shown in Table 1, in the same way as the above method A (for coloring can be Preparation of Curing Composition) The colored curable compositions of Examples 2 to 8 were obtained in the same manner. In addition to changing the type of dye and the type and composition ratio of organic solvents as shown in Table 1, and changing the amount of solvent to give the solid content shown in Table 1, in the same way as the above method B (for coloring can be The colored curable compositions of Comparative Examples 2 to 8 were obtained in the same manner as in Preparation of Curable Compositions). As described above, since the amount of the organic solvent is changed, the solid content of the colored curable composition is changed. Using each of the obtained colored curable compositions, dispersion stabilit...

Abstract

A method of preparing a color curable composition, comprising: preparing a dye solution by dissolving at least a dye in an organic solvent; preparing a pigment dispersion liquid by dispersing at least a pigment using a dispersant; and mixing the dye solution and the pigment dispersion liquid.

Description

technical field [0001] The present invention relates to a colored curable composition and a preparation method thereof, a color filter and a preparation method thereof, and a solid-state imaging device. Background technique [0002] The pigment dispersion method is widely known as a method for producing color filters used in liquid crystal display devices such as LCD and solid-state imaging devices such as CCD and CMOS. [0003] The pigment dispersion method is a method in which a color filter is produced by photolithography using a colored curable composition containing a pigment dispersed in a photosensitive composition, which can be selected from various photosensitive compositions. The pigment dispersion method achieves high positional accuracy due to the use of photolithography for patterning, and is suitable for the production of large-area high-precision color filters. The production of a color filter by a pigment dispersion method includes: applying a colored curabl...
