Problems solved by technology

Generally speaking, triarylmethane dyes have high transmittance at 420-450nm and have an effect on color characteristics, but their chemical corrosion resistance decreases due to their higher solubility than pigments, and they are less effective in color filters due to their lower heat resistance than pigments. limited use in

manufacture example 1

[0208] [Production Example 1] Production of Compound A

[0209]

[0210] To 0.55 g (0.38 mmol, 1.2 eq) of naphthalene-1-amine, 1 mL of AcOH, 0.3 g (0.31 mmol, 1 eq) of cyclohexanone, and 1 mL of dichloromethane were added, followed by stirring for about 30 minutes. Thereafter, slowly add NaBH(OAC) 3 1.0 g (4.7 mmol, 1.5 eq). After stirring at room temperature for about 16 hours, distilled water was added, extracted with dichloromethane, and the organic layer was dried over sodium sulfate and dried under reduced pressure. The obtained product was purified with a column (ethyl acetate:hexane=1:9 ratio) to obtain 0.74 g of Compound A. (yield 86%)

manufacture example 2

[0211] [Production Example 2] Production of Compound B

[0212]

[0213] 50 ml of dimethylformamide (DMF) was added to 3.7 g (0.026 mol, 1 eq) of naphthalene-1-amine, and 17.85 g (0.13 mol, 5 eq) of potassium carbonate was slowly added at room temperature, followed by stirring for 30 minutes. Then, 7.8 g (0.065 mol, 2.5 eq) of allyl bromide was added, and it stirred at room temperature for 4 hours. After completion of the reaction, distilled water was added, extracted with ether, and the organic layer was dried over sodium sulfate and dried under reduced pressure. The obtained product was purified by column (ethyl acetate:hexane=1:100-1:80 ratio), and 1.5 g of compound B was obtained in 34% yield.

manufacture example 3

[0214] [Production Example 3] Production of Compound C

[0215]

[0216] To 3.0 g (0.021 mol, 1 eq) of naphthalene-1-amine was added 30 mL of dichloromethane, and 2.75 g (0.027 mol, 1.3 eq) of triethylamine was slowly added at room temperature. Then, methacrylic acid 4.8g (0.056mol, 2.7eq) was added, and it stirred at normal temperature for 16 hours. After completion of the reaction, distilled water was added, extracted with dichloromethane, and the organic layer was dried over sodium sulfate and dried under reduced pressure. The obtained product was purified by column (ethyl acetate:hexane=1:10-1:15 ratio), and 0.9 g of compound C was obtained in 20% yield.

Abstract

The present specification relates to a novel compound, a coloring composition including the same, and a resin composition including the same. The compound is represented by chemical formula 1. The compound has excellent solubility with respect to a solvent and excellent chemical resistance.

Description

technical field [0001] This specification relates to a novel compound, a colorant composition containing the novel compound, and a resin composition containing the novel compound. Background technique [0002] In recent years, elements such as LEDs, OLEDs, and QDs are often used as light sources for liquid crystal displays (LCDs) instead of conventional CCFLs. However, in order to make thin-film displays and flexible displays, etc., display products that remove color filters, that is, use self-luminescence such as LEDs, OLEDs, and QDs as unit pixels, have been developed and produced. [0003] However, it is difficult to increase the area of ​​displays using LEDs, OLEDs, QDs, etc. as unit pixels. When LEDs, OLEDs, QDs, etc. are used, many efforts have been made to develop displays that include them as light sources and include color filters. [0004] In order to express a desired color, a light source and an appropriate color filter are required, and at present, a pigment di...
