Embodiment

[0389] Next, examples will be given to further describe the present invention in detail. In the examples, unless otherwise specified, % and parts indicating the content or usage amount are based on mass.

Synthetic example 1

[0391] 20 parts of the compound represented by the formula (1a) and 200 parts of N-ethyl-o-toluidine (manufactured by Wako Pure Chemical Industries, Ltd.) were mixed under light-shielding conditions, and the obtained solution was stirred at 110° C. for 6 hours. After cooling the obtained reaction liquid to room temperature, it added to the mixed liquid of 800 parts of water and 50 parts of 35% hydrochloric acid, and stirred at room temperature for 1 hour, and the crystal was deposited. The precipitated crystal as the residue was collected by suction filtration and dried to obtain 24 parts of the compound represented by the formula (1-1). The yield was 80%.

[0392]

[0393] The structure of the compound represented by the formula (1-1) was confirmed by mass spectrometry (LC; Agilent 1200 type, MASS; Agilent LC / MSD type).

[0394] (Mass spectrometry) ionization mode = ESI+: m / z = [M+H] + 603.4

[0395] Exact Mass: 602.2

Synthetic example 2

[0397] Except that N-isopropyl-o-toluidine was used instead of N-ethyl-o-toluidine, the compound represented by formula (1-5) was obtained as in Synthesis Example 1.

[0398] Identification of compounds represented by formula (1-5)

[0399]

[0400] (Mass spectrometry) ionization mode = ESI+: m / z = [M+H] + 632.3

[0401] Exact Mass: 631.3

Abstract

A colored curable resin composition comprises a colorant, resin, a polymerizable compound and a polymerization initiator. The colorant contains a compound shown by formula (1). In formula (1), R1 and R2 each independently represents a phenyl which may have substituted groups; R3 and R4 each independently represents a saturated hydrocarbyl having 1 to 10 carbon atoms; R5 represents -OH,-SO3H,-8O2NR9R10, etc. R6 and R7 each independently represents a hydrogen atom or an alkyl group having 1 to 6 carbon atoms. m represents an integer of 0 to 4. R9 and R10 each independently represents a hydrogen atom or a monovalent saturated hydrocarbon group having 1 to 20 carbon atoms.

Description

technical field [0001] The present invention relates to a colored curable resin composition. Background technique [0002] It is known that the colored curable resin composition is used for the production of color filters used in display devices such as liquid crystal display panels, electroluminescence panels, and plasma display panels. As such a colored curable resin composition, there is known a colored curable resin composition (JP2010-211198-A) containing a compound represented by formula (A2-1a) and a compound represented by formula (A2-1b). The dye after sulfonamidation of the compound with 2-ethylhexylamine and C.I. Pigment Blue are used as colorants. [0003] [0004] With the above conventionally known colored curable resin composition, the brightness of the color filter obtained by the colored curable resin composition is not sufficiently satisfactory. Contents of the invention [0005] The present invention includes the following inventions. [0006] [1] ...
