Embodiment

[0396] Hereinafter, the colored curable resin composition of the present invention will be described in more detail through examples.

[0397] Unless otherwise specified, "%" and "part" in an example are mass % and a mass part.

[0398] 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; (Elementar Co., Ltd.)).

Synthetic example 1

[0400] 15 parts, To 150 parts of chloroform and 8.9 parts of N,N-dimethylformamide, 10.9 parts of thionyl chloride were added dropwise while maintaining the temperature below 20°C under stirring. After completion of the dropwise addition, the temperature was raised to 50°C, and the same temperature was maintained for 5 hours to allow a reaction, and then cooled to 20°C. While maintaining the cooled reaction solution at 20° C. or lower with stirring, a mixed solution of 12.5 parts of 2-ethylhexylamine and 22.1 parts of triethylamine was added dropwise. Then, it stirred at the same temperature for 5 hours and made it react. Next, after distilling off the solvent from the obtained reaction mixture with a rotary evaporator, a small amount of methanol was added and vigorously stirred. This mixture was added to a mixed liquid of 375 parts of ion-exchanged water while stirring, and crystals were precipitated. The precipitated crystals were filtered, thoroughly washed with ion-exch...

Synthetic example 2

[0403] 20 parts of the compound represented by the formula (1x) and 200 parts of N-ethyl-o-toluidine (manufactured by Wako Pure Chemical Industries, Ltd.) were mixed under light-shielding conditions, and the resulting solution was stirred at 110° C. for 6 hours. After cooling the obtained reaction liquid to room temperature, it was added to the liquid mixture of 800 parts of water and 50 parts of 35% hydrochloric acid, and it stirred at room temperature for 1 hour, and a crystal precipitated. The precipitated crystal was obtained as a suction-filtered residue and dried to obtain 24 parts of the compound represented by the formula (1-24). The yield is 80%.

[0404]

[0405] The structure of the compound represented by the formula (1-24) was confirmed by mass spectrometry (LC; Agilent 1200 type, MASS; Agilent LC / MSD type).

Abstract

Provided is a colored curable resin composition, comprising a coloring agent, resin, polymer compound and polymerization initiator, wherein the coloring agent has xanthene dyes, tetrazaporphyri dyes containing the compound expressed by the following formula (1b) and pigment. In the formula (1b), R41-R48 respectively represents hydrogen atom, halogen atom, cyano group, replaced or non-replaced alkyl group, replaced or non-replaced alkoxy, replaced or non-replaced aryl group, replaced or non-replaced aryloxy, replaced or non-replaced aralkyl oxygroup, replaced or non-replaced amine; M represents two hydrogen atoms, two mono-valence metallic atoms, a bivalence metallic atom, a trivalence replaced metallic atom or an oxidized metallic atom.

Description

technical field [0001] The present invention relates to a colored curable resin composition. Background technique [0002] The colored curable resin composition is used for manufacture of the color filter used for display devices, such as a liquid crystal display panel, an electroluminescence panel, and a plasma display panel. As such a colored curable resin composition, a colored curable resin composition containing only xanthene dye and C.I. Pigment Blue 15:6 as a colorant (JP2010-32999-A), and a xanthene dye containing , C.I. Pigment Blue 15:6, and a colored curable resin composition using a phthalocyanine dye as a colorant (JP2011-28236-A). [0003] However, the contrast of the color filter obtained with the said colored curable resin composition known conventionally is not necessarily sufficient. Contents of the invention [0004] The inventors of the present invention conducted studies to solve the above-mentioned problems, and as a result, completed the present in...
