Embodiment 1
[0462] Synthesis Example 1: Synthesis of Compound 1 corresponding to a specific oxime compound N-hydroxyxime (10.00 g, 19.0 mmol) and triethylamine (2.31 g, 22.8 mmol) having the structure shown below were dissolved in 200 ml of THF and Cool to 0 °C. Acetyl chloride (1.79 g, 22.8 mmol) was then added dropwise thereto. After the mixture was stirred at room temperature for 1 hour, 100 ml of distilled water was added thereto, and the organic layer was extracted with ethyl acetate. After removing the solvent by distillation under reduced pressure, the obtained residue was purified by silica gel chromatography (ethyl acetate / hexane=1 / 4) to obtain Compound 1 having the structure shown below (9.5 g, 88% yield ).
[0463] Compound 1
[0464] Using an ultraviolet-visible spectrophotometer (trade name: CARRY-5 Spectrophotometer, manufactured by Varian), the obtained molar absorptivity of Compound 1 at 365 nm was measured in an ethyl acetate solution at a concentration of 0.01 g / L a...
Embodiment 2
[0465] Synthesis Example 2: Synthesis of Compound 7 corresponding to a specific oxime compound N-hydroxyxime (10.00 g, 22.9 mmol) and triethylamine (2.78 g, 27.5 mmol) having the structure shown below were dissolved in 200 ml of THF and Cool to 0 °C. Acetyl chloride (2.16 g, 27.5 mmol) was then added dropwise thereto. After the mixture was stirred at room temperature for 1 hour, 100 ml of distilled water was added thereto, and the organic layer was extracted with ethyl acetate. After the solvent was removed by distillation under reduced pressure, the precipitated crystals were recrystallized from methanol to obtain Compound 7 (9.2 g, 84% yield) of the structure shown below.
[0466] Compound 7
[0467] Using an ultraviolet-visible spectrophotometer (trade name: Carry-5 Spectrophotometer, manufactured by Varian), the obtained molar absorptivity of Compound 7 at 405 nm was measured in an ethyl acetate solution at a concentration of 0.01 g / L and found to be 21,380. The struc...
Embodiment 2-11
[0475] Example 2-11. Preparation of Colored Curable Composition A-1 A negative coloring curable composition (A-1) containing a colorant (pigment) was prepared as a curable composition for forming a color filter. A color filter was produced using this colored curable composition.
[0476] 1-1. Preparation of pigment dispersion (P1) 40 parts by mass of C.I. Pigment Green 36 and C.I. Pigment Yellow 219 (mass ratio 30 / 70) of the pigment mixture, 10 parts by mass (4.51 parts by mass in terms of solid content) A liquid mixture consisting of BYK 2001 (DISPERBYK, manufactured by BYK-Chemie, 45.1% by mass in terms of solid content) as a dispersant, and 150 parts by mass of ethyl 3-ethoxypropionate as a solvent in a bead mill Mixing and dispersion were carried out for 15 hours to prepare a pigment dispersion liquid (P1).
[0477] The average particle size of the pigment in the obtained pigment dispersion (P1) was 200 nm as measured by dynamic light scattering.
