Embodiment

[0334] 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.

[0335]

Synthetic example 1

[0337] (Synthesis of Polymer (1))

[0338] Add 5.46g p-(vinylphenyl)trifluoromethanesulfonylimide acid triethylamine salt, 4.51g methyl methacrylate, 0.130g α-thioglycerol to the reaction vessel equipped with condenser, and make They are dissolved in 20 g of cyclohexanone. The solution was heated to 100°C while stirring under nitrogen flow. A solution obtained by dissolving 98.0 mg of α,α'-azobisisobutyronitrile in 10.4 g of cyclohexanone was added dropwise over 30 minutes while stirring at the same temperature, and stirring was continued at the same temperature for 3 hours after the completion of the dropwise addition. Then, after cooling the reaction solution to room temperature, 60 g of acetone was added to make a uniform solution, which was added dropwise to 1.1 L of hexane. The resulting precipitate was collected by filtration and washed with hexane. The obtained solid was dried under reduced pressure at 50° C. to obtain 8.14 g of a polymer represented by the following...

Synthetic example 2

[0344] (Synthesis of Polymer (2))

[0345] In the synthesis of polymer (1), tetraethylammonium p-styrenesulfonate was used instead of triethylamine p-(vinylphenyl)trifluoromethanesulfonimidate, and the synthesis example 1 Similarly, 8.29 g of a polymer (2) represented by the following structural formula was obtained. The Mw of the obtained polymer (2) is 8800, and the Mn is 4300, by 1 H-NMR analysis confirmed that the ratio of p to r was 1 / 2.8 in molar ratio (p / r).

[0346]

[0347] (Synthesis of Polymer B)

[0348] In the synthesis of polymer A, 2.50 g of a polymer represented by the following structural formula was obtained in the same manner as in Synthesis Example 1, except that polymer (2) was used instead of polymer (1) as shown in the following flow diagram b. Polymer B is not the present colorant.

Abstract

The invention refers to a coloring composition, a coloring immobilizing membrane and a display element. The coloring composition is suitable for forming a coloring immobilizing membrane which has heat resistance and solvent resistance, restrains migration property and possesses dye. The coloring composition includes a colorant (A) and a polymerized compound (C). The colorant includes a compound of a structural unit represented by the following formula (1). In the formula (1), R0 represents hydrogen atom or methyl; X represents halogen group, halogenated hydrocarbon, or linking group perssad with atoms among halogenated hydrocarbon C-C keys, the atoms not including carbon atoms, hydrogen atoms or halogen atoms; Y represents single bond or bivalent organic group; Z+ represents at least one positive ion chromophore selected from the group of three aryl methane series, methyne series, azo series, diaryl methane series, quinone imine series, anthraquinone series, phthalocyanine series and xanthenes series.

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 color liquid crystal display element for use in a transmissive or reflective color liquid crystal display element, a solid-state imaging element, an organic EL display element, and electronic paper. A coloring composition for a colored cured film, a colored cured film formed using the colored composition, and a display element including the colored cured film. Background technique [0002] When producing a color filter using a colored radiation-sensitive composition, it is known to apply a pigment-dispersed colored radiation-sensitive composition on a substrate and dry it, and then irradiate the dried coating film with radiation in a desired pattern (hereinafter , referred to as “exposure”) and developing to obtain pixels of each color (for example, refer to Patent Documents 1 and 2). Moreover, the method of forming a...
