Embodiment

[0486] Hereinafter, the colored curable resin composition of the present invention will be described in more detail by way of examples. Unless otherwise specified, "%" and "part" in an example are mass % and a mass part.

[0487] In the following synthesis examples, compounds were identified by mass spectrometry (LC; Agilent 1200 type, MASS; Agilent LC / MSD type) or elemental analysis (VARIO-EL; (Elementer Co., Ltd.)).

Synthetic example 1

[0489] In the reactor, 32.3 parts of pararosaniline hydrochloride (manufactured by Tokyo Chemical Industry Co., Ltd.) was added to 500 parts of absolute ethanol, refluxed for 8 hours, and cooled to room temperature. 20.2 parts of compounds represented by formula (a2-1) were slowly added dropwise to the obtained mixture over 5 hours. After the dropwise addition, the obtained mixture was stirred at 70° C. for 36 hours, and then cooled to room temperature to obtain 48.8 parts of a compound represented by the formula (a2).

[0490]

Synthetic example 2

[0492] 50 mL of methylene chloride was added to 28.52 parts of bis-N-ethyl-N-hydroxyethylaminobenzophenone and 17.80 parts of triethylamine, followed by stirring and dissolving. Then, 13.56 parts of methacrylic anhydride was added, and it heated up to 40 degreeC, and maintained. After the reaction was completed and cooled to room temperature, water was added to separate the layers, 20 mL of saturated saline was added, and the mixture was stirred for 30 minutes. After layer separation, the organic layer was distilled off, and the remaining solid was dried under reduced pressure to obtain 21.4 parts of the compound represented by the formula (aa2).

[0493]

[0494] 21.4 parts of the compound represented by formula (aa2) were added to 500 mL of chloroform, and stirred. Then, 49.08 parts of phosphorus oxychloride was added and stirred for 15 minutes. After adding 14.56 parts of N-phenyl-1-naphthylamine, it was made to reflux. After the reaction was completed, after cooling ...

Abstract

Provided is a color filter having excellent thermal resistance and color values. The colored curable resin composition contains a colorant (A), a resin (B), a polymerizable compound (C) and a polymerization initiator (D), the colorant (A) containing at least one selected from the group consisting of compounds represented by formula (a), xanthene dye, and salts of xanthene dye and cyanine dye [in the formula, k1, k2, k3 and k4 each independently represents an integer in the range 0-4, and 1<=k1+k2+k3+k4<=16. Xa-, Xb-, Xc- and Xd- each independently represents -CO3- or -SO3-. Aa<+>, Ab<+>, Ac<+> and Ad<+> each independently represents a sodium ion, a potassium ion, or a cation represented by formula (b). In formula (b), R100, R101, R102, and R103 each independently represents a hydrogen atom or a C1-30 hydrocarbon group.].

Description

technical field [0001] The present invention relates to a colored curable resin composition. Background technique [0002] Color filters made of colored curable resin compositions are used in display devices such as liquid crystal display panels, electroluminescent panels, and plasma display panels, and color filters with good brightness, good contrast, and good resolution are required . [0003] In order to realize a color filter having good lightness, good contrast, and good resolution, a colored curable resin composition containing a dye as a colorant has been studied, but heat resistance, chemical resistance, etc. The problem of reduced sex and so on. [0004] Patent Document 1 describes a colored curable resin composition, which is a colored curable resin composition containing C.I. Pigment Blue 15:6 and C.I. Acid Red 52 and a dye represented by the following formula as a colorant. The content of C.I. Pigment Blue 15:6 and C.I. Acid Red 52 is 14.7 parts by mass. [...
