Embodiment

[0451] Hereinafter, the present invention will be specifically described with reference to examples. The present invention is not limited to these descriptions.

[0452] In addition, the weight average molecular weight Mw of a basic copolymer in this invention is calculated|required as the standard polystyrene conversion value by GPC (gel permeation chromatography). For the measurement, HLC-8120GPC manufactured by Tosoh Co., Ltd. was used, and N-methylpyrrolidone added with 0.01 mol / liter of lithium bromide was used as the eluting solvent, and the calibration curve was set to Mw377400, 210500, 96000, 50400 using polystyrene standards. , 20650, 10850, 5460, 2930, 1300, 580 (the above are Easi PS-2 series manufactured by Polymer Laboratories Co., Ltd.) and Mw1090000 (made by Tosoh Co., Ltd.), TSK-GEL ALPHA-M × two roots (Tosoh Co., Ltd. ) system) was performed as a measuring column. In addition, also about the macromonomer or graft copolymer used as the raw material of a basic...

[0455] 15.2 g (60 mmol) of 1-iodonaphthalene produced by Wako Pure Chemical Industries, Ltd., 4.63 g (30 mmol) of norbornanediamine (NBDA) (CAS No.56602-77-8) produced by Mitsui Chemicals Co., Ltd., tert-butyl 8.07 g (84 mmol) of sodium alkoxide, 0.09 g (0.2 mmol) of 2-dicyclohexylphosphino-2',6'-dimethoxybiphenyl manufactured by Aldrich, 0.021 g (0.1 mmol) of palladium acetate manufactured by Wako Pure Chemical Industries, Ltd. mmol) was dispersed in 30 mL of xylene, and reacted at 130-135°C for 48 hours. After the reaction, cool to room temperature and add water for extraction. Then, it was dried over magnesium sulfate and concentrated to obtain 8.5 g (yield 70%) of intermediate 1 represented by the following chemical formula (1).

[0456] The obtained compound was confirmed to be the target compound by the analysis results described below.

Abstract

Provided is a coloring material dispersion whereby a coating film can be formed which has excellent stability over time and enhanced heat resistance. A coloring material dispersion containing a coloring material represented by general formula (I), a dispersing agent, an organic acid compound, and a solvent, the dispersing agent being a block copolymer having at least structural units (a) represented by general formula (II) and having an amine value of 70 mg KOH / g to 160 mg KOH / g, the solvent being a solvent in which the solubility of the coloring material at 23 DEG C is 0.1 (g / 10 mL solvent) or lower, and the coloring material dispersion satisfying expressions (1) and (2), and satisfying expression (3) when X is in a range less than 1. Expression (1): X <= 1.5. Expression (2): A X X >= 40. Expression (3): A X (1 -X) <= 42. (The reference symbols in expressions (1) through (3) and general formulas (I) and (II) are as described in the specification.)

Description

technical field [0001] The present invention relates to a color material dispersion, a colored resin composition for a color filter, a color filter, and a display device. Background technique [0002] Thin image display devices typified by monitors, ie so-called flat panel displays, are thinner than cathode ray tube displays and take up less space in the depth direction, and have been marketed in large numbers. With the evolution of production technology, its market price tends to be reasonable year by year, and then the demand expands, and the production volume also increases year by year. In particular, color LCD TVs have almost become the mainstream of TV. In addition, recently, an organic light-emitting display device such as an organic EL display with high visibility due to self-luminescence is also attracting attention as a next-generation image display device. Regarding the performance of these image display devices, further improvement in image quality, such as imp...
