Embodiment

[0862] Hereinafter, examples are given to describe the present invention more specifically, but the present invention is of course not limited by the following examples, and of course it can also be implemented with appropriate changes within the range that can be adapted to the purposes described above and below, and they are all included in The technical scope of the present invention.

[0863] (1) Polymethyl compounds

[0864] Polymethyl compound synthesis examples 1-54

[0865] 0.01 mol of indolenine intermediate and 16 g of pyridine or acetonitrile were mixed, 0.012 mol of acetic anhydride was added dropwise, and stirred at room temperature to 50° C. for 1 hour. Add 0.01 mol of active methylene compound and 0.02 mol of triethylamine, and stir at room temperature to 50° C. for 1 to 3 hours. The obtained solid was purified by reflux with methanol, and the solid was dried at 120° C. to obtain the target product. The analysis results are shown in [Table 1] to [Table 6].

Synthetic example 55

[0878] [Synthesis Example 55 of Polymethyl Compounds] Production of Compound No. 84

[0879] 0.2 g of Compound No. 31 and 20 g of ion-exchanged water were mixed, and an aqueous sodium hydroxide solution was added dropwise to homogenize the solution. An aqueous solution of 0.062 g of barium chloride dihydrate was charged thereinto, and stirred for 30 minutes. The obtained solid was filtered, washed with water, and dried to obtain 0.19 g of the target product (yield: 82.5%).

Synthetic example 56

[0880] [Synthesis Example 56 of Polymethyl Compounds] Production of Compound No. 85

[0881] Except having used copper sulfate pentahydrate instead of barium chloride dihydrate, 0.07 g (yield 33.3%) of the target object was obtained similarly to polymethyl compound synthesis example 55.

Abstract

The chromaticity of a colored curable resin composition for manufacturing a colored filter, or like is further improved. The colored curable resin composition contains a colorant (A), a resin (B), a polymerizable compound (C), and a polymerization initiator (D). The colorant (A) comprises a compound (A1) represented by the formula (I) shown in the description and a colorant (A2) having an absorption wavelength no less than 500nm and no more than 700 nm in chloroform.

Description

technical field [0001] The present invention relates to a colored curable resin composition containing a specific compound having a polymethyl structure. Background technique [0002] Polymethyl compounds such as merocyanines are used, for example, in optical filters (Patent Document 1). In the column of Examples of this Patent Document 1, an optical filter was produced using iodized salts of the following compounds No. 2 and No. 3. [0003] [chemical formula 1] [0004] [0005] However, in the above-mentioned Patent Document 1, there is no evaluation of the lightness of the color filter. [0006] It is desired to further increase the lightness of a colorant having a maximum absorption wavelength of 500 nm or more and 700 nm or less. As an example of using such a colorant, Patent Document 2 discloses an example in which a specific xanthene dye is combined with Pigment Red 254, and Patent Document 3 discloses an example in which Pigment Red 242 and Pigment Red 177 are ...
