preparation example Construction

[0466] [Preparation method of coloring composition]

[0467] The coloring composition of the present invention is prepared by mixing the above-mentioned components and optional optional components.

[0468] Moreover, when preparing a coloring composition, each component which comprises a coloring composition may be mix|blended collectively, and each component may be melt|dissolved and dispersed in a solvent, and you may mix|blend sequentially. In addition, there are no particular restrictions on the input order or working conditions at the time of deployment. For example, a composition can be prepared by dissolving and dispersing all the components in a solvent at the same time, and if necessary, two or more kinds of solutions and dispersions can be prepared appropriately for each component, and they can be mixed at the time of use (at the time of coating) to prepare compositions.

[0469] The coloring composition prepared in this manner can be used after being separated by ...

[0545] (Synthesis of Compound 1-2)

[0546] Compound 1-2 was synthesized according to the following route.

[0547] [Chemical 54]

[0548]

[0549] (Synthesis of Synthetic Intermediate (Compound 3))

[0550] After dissolving 17.0 g (118.8 mmol) of compound 1 (1-naphthylamine) and 11.65 g (118.7 mmol) of 1,2-epoxycyclohexane in 50 mL of hexafluoroisopropanol, it was heated to reflux for 5 hours. After confirming the completion of the reaction, the target substance was extracted into the organic layer with 50 mL of ethyl acetate, water, and saline, washed, and then concentrated. The crude product was dissolved in hexane, recrystallized, and then filtered to obtain 19.2 g of Compound 3 (67% yield).

The colored composition according to the present invention comprises: a coloring agent which contains a triarylmethane structure having a crosslinking group and a cation and having a molecular weight of 2000 or less and a counter anion; and a polymerizable compound.

Description

technical field [0001] The present invention relates to a coloring composition, a cured film, a color filter, a method for producing the color filter, a solid-state imaging element, and a liquid crystal display device. Background technique [0002] Conventionally, color filters are manufactured by containing a pigment dispersion composition obtained by dispersing an organic pigment or an inorganic pigment, a polyfunctional monomer, a polymerization initiator, an alkali-soluble resin, and other components as needed. A coloring composition is produced, and then a coloring pattern is formed by using the coloring composition by photolithography, an inkjet method, or the like to manufacture a color filter. [0003] In recent years, color filters tend to be used not only for monitors but also for televisions (Television, TV) in liquid crystal display (Liquid Crystal Display, LCD) applications. With the trend of expanding applications, color filters are required to have high color...
