Embodiment

[0289] Hereinafter, an Example is given and the embodiment of this invention is demonstrated more concretely. However, the present invention is not limited to the following examples.

[0290]

Synthetic example 1

[0292] A 100mL three-neck flask equipped with a stirring bar and a reflux cooling tube and a thermometer was fully replaced with nitrogen, 15.0g of cyclohexanone was added, and heated to an internal temperature of 80±2°C under nitrogen flow. 4.50 g of pigment monomer (A1) represented by the following formula, 6.00 g of methyl methacrylate, 4.50 g of methacrylic acid, As a polymerization initiator, 2.18 g of 2,2'-azobis(2,4-dimethylvaleronitrile) (manufactured by Wako Pure Chemical Industries, Ltd., trade name V-65) and 45.0 g of cyclohexanone were prepared by The solution. After completion of the dropwise addition, stirring was further continued at this temperature for 1 hour. Thereafter, the reaction liquid was cooled to room temperature and added dropwise to a large amount of hexane. The obtained colored solid was dried under reduced pressure at 50° C. to obtain 14.1 g of a polymer (1). The Mw of the obtained polymer (1) was 4800. Polymer (1) corresponds to polymer α.

Abstract

The invention provides a coloring composition, a coloring cured film and a display device. The coloring composition herein is suitable for forming a coloring cured film having excellent heat resistance and high contrast ratio. The coloring composition herein contains a (A) coloring agent and a (B) polymer compound, wherein the (A) coloring agent includes a combination between at least one to be selected from either a monomer ([alpha]3) or a polymer ([alpha]3) and at least one to be selected from either a monomer ([belta]3) and a polyer ([beta]4)(wherein, exclusive of the case when the (A) coloring agent is a combination between the monomer ([alpha]3) and the polymer ([beta]4)), the monomer ([alpha]3) including at least one chromophore group and one polymerized group to be selected from xanthene chromophore group or cyanin chromophore group, the polymer ([beta]4) containing the monomer ([alpha]3) as a structure unit, the monomer ([alpha]3) including at least one chromophore group and one polymerized group to be selected from triarylmethane and anthraquinone chromophore group, the polymer ([beta]4) containing the monomer ([alpha]3) as a structure unit.

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 composition for forming a colored cured film, a colored cured film formed using the colored composition, and a display provided with the colored cured film. Devices, the colored cured film is suitable for transmissive or reflective color liquid crystal display devices, solid-state imaging devices, organic EL display devices, electronic paper, and the like. Background technique [0002] When producing a color filter using a colored radiation-sensitizing composition, a method is known in which a pigment-dispersed colored radiation-sensitizing composition is coated on a substrate and dried, and then the dried coating film is formed into a desired pattern shape. By irradiating radiation (hereinafter referred to as "exposure") and developing, pixels of each color are obtained (for example, refer to Patent Documents ...
