[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 ...
Embodiment
[0543] Examples are given below to further describe the present invention in detail. Materials, usage amounts, ratios, processing contents, processing procedures, and the like shown in the following examples can be appropriately changed as long as they do not depart from the gist of the present invention. Therefore, the scope of the present invention is not limited to the specific examples shown below. In addition, unless otherwise specified, "%" and "part" are based on mass.
Synthetic example 1
[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).
[0551] (Synthesis of Synthetic Intermediate (Compound 4))
[0552] Compound 3 (2.4 g (10 mmol)) and triethylamine 1.5 g (15 mmol) were dissolved in 10 mL of tetrahydrofuran (THF). After cooling the said solution to 0 degreeC, 1.15 g (11 mol) of methacryloyl chlorides were dri...
