Embodiment

[0447] Hereinafter, the present invention will be specifically described with reference to examples. However, the present invention is not limited to these descriptions.

Synthetic example 1

[0448] (Synthesis Example 1: Synthesis of Intermediate 1)

[0449] 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 oxide, 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 18.5 g of an intermediate represented by the following chemical formula (1) (yield: 70%).

[0450] The obtained compound was confirmed to be the target compound by the analysis results described below.

Synthetic example 2

[0456] (Synthesis Example 2: Synthesis of Intermediate 2)

[0457] Put 8.46 g (20.8 mmol) of intermediate 1, 13.5 g (41.6 mmol) of 4,4′-bis(dimethylamino)benzophenone manufactured by Tokyo Chemical Industry Co., Ltd., and 60 mL of toluene, and stir at 45-50°C . 6.38 g (51.5 mmol) of phosphorus oxychloride manufactured by Wako Pure Chemical Industries, Ltd. was added dropwise, refluxed for 2 hours and cooled. After the reaction was over, toluene was decanted. Add 40 mL of chloroform, 40 mL of water, and concentrated hydrochloric acid to dissolve the resinous precipitate, and separate the chloroform layer. The chloroform layer was washed with water, dried over magnesium sulfate, and concentrated. 65 mL of ethyl acetate was added to the concentrate and refluxed. After cooling, the precipitate was filtered to obtain 15.9 g (70% yield) of an intermediate (BB7-Nb-dimer) represented by the following chemical formula (2).

[0458] The obtained compound was confirmed to be the tar...

Abstract

A colored resin composition for a color filter is provided which can form a colored layer having excellent stability of sensitivity over time and excellent substrate adhesion, heat resistance and solvent resistance, and in which water stains during development are suppressed. This colored resin composition for a color filter contains a lake colorant, a dispersant, an alkali soluble resin, a polyfunctional monomer, an initiator and a solvent. The alkali soluble resin has a hydrocarbon ring and an ethylenic double bond, and has an acid value of 80-300 mgKOH/g. The content ratio of a silane coupling agent to the total solid content in the colored resin composition is 1 mass% or less.

Description

technical field [0001] The invention relates to a colored resin composition for a color filter, a color filter and a display device. Background technique [0002] Thin image display devices such as monitors, so-called flat panel displays, are characterized by being thinner than cathode ray tube displays and occupying less space in the depth direction, and many of them have been put on the market. 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 roughly become the mainstream of TV. In addition, recently, organic light-emitting display devices such as organic EL displays with high visibility due to self-luminescence are also attracting attention as next-generation image display devices. With respect to the performance of such image display devices, further improvement in image quality, such as improvement in c...
