Embodiment

[0279] Hereinafter, an Example is given and the embodiment of this invention is demonstrated further concretely. However, the present invention is not limited to the following examples.

[0280]

Synthetic example 1

[0282] A 100mL three-neck flask with a stirring bar, a reflux cooling tube, and a thermometer is fully replaced with nitrogen, and 15.0g of cyclohexanone is charged, and heated to an internal temperature of 80±2°C under nitrogen flow. On the other hand, 4.00 g of the dye monomer (A1) shown below, 0.50 g of the dye monomer (A3) shown below, 6.00 g of methyl methacrylate, and 4.50 g of methyl Acrylic acid, 2.18 g of 2,2'-azobis(2,4-dimethylvaleronitrile) (manufactured by Wako Pure Chemical Industries, Ltd., trade name V-65) as a polymerization initiator, 45.0 g of cyclohexanone The prepared solution was maintained at an internal temperature of 80±2° C., and was added dropwise over 2 hours using a pump. After completion of the dropwise addition, stirring was continued at this temperature for another 1 hour. Thereafter, the reaction solution was cooled to room temperature and added dropwise to a large amount of hexane. The obtained colored solid was dried under reduced pressure ...

Synthetic example 2～10

[0285] In Synthesis Example 1, polymers (2) to (10) were obtained in the same manner as Synthesis Example 1 except that the type and amount of monomers used for polymerization were changed as shown in Table 1. The structures of the dye monomers (A1) to (A4) are as above. Polymers (2) to (4) and polymers (9) to (10) correspond to polymer (A1). Polymers (5) to (8) are not polymer (A1).

[0286]

[0287] The symbols used in Table 1 are as follows.

[0288] MMA: methyl methacrylate

[0289] MA: methacrylic acid

[0290] In addition, "p / q" in Table 1 indicates that when the number of moles of the compound represented by the formula (1-1) used for polymerization is p, and the number of moles of the compound represented by the formula (1-2) is represented by q molar ratio.

[0291] In addition, the dye monomers (A1) to (A4) were synthesized with reference to the following publications, respectively.

[0292] Dye monomer (A1): synthesized according to Synthesis Example 2 desc...

Abstract

The invention discloses a coloring composition, a coloring cured film and a display device. The invention aims at providing a coloring composition which is suitable for forming a coloring cured film having excellent heat resistance and high contrast ratio. The coloring composition herein is a coloring composition containing a (A) coloring agent and a (B) polymer compound, wherein the coloring agent has a portion which generates fluorescence and a polymer which absorbs the fluorescence.

Description

technical field [0001] The present invention relates to a colored composition, a colored cured film, and a display element. More specifically, it relates to a colored cured film used in a transmissive or reflective color liquid crystal display element, a solid-state imaging element, an organic EL display element, and electronic paper. The coloring composition used, the colored cured film formed using this coloring composition, and the display element provided with this colored cured film are formed. Background technique [0002] When producing a color filter using a colored radiation-sensitive composition, a method is known in which a pigment-dispersed colored radiation-sensitive composition is coated on a substrate and dried, and then the dried coating film is irradiated in a desired pattern shape. A method of obtaining pixels of each color by radiating (hereinafter referred to as "exposure") and developing (for example, refer to Patent Documents 1 and 2). Moreover, the me...
