Embodiment 1

[0266] Hereinafter, examples are given to further specifically illustrate the embodiments of the present invention. However, the present invention is not limited to the following embodiments.

[0267]

Synthetic example 1

[0269] Synthesis of dye monomer

[0270] Into a 1L three-necked flask with a stir bar and nitrogen replacement in advance was added tris(dibenzylideneacetone)-dipalladium(0) 3.36g (3.67mmol), (±)-2,2'-bis(two (Phenylphosphino)-1,1'-binaphthalene 4.58g (7.36mmol), and 450mL of 1,2-dimethoxyethane degassed by nitrogen bubbling in advance, and stirring at 80°C under nitrogen flow 1 hour. After that, the mixture was cooled to below 40°C, while preventing air from entering the system, 25.0 g (0.260 mol) of sodium tert-butoxide, 23.0 g (0.200 mol) of 4-aminocyclohexanol, and 1-bromonaphthalene were added in sequence. 38.0 g (0.184 mol), stirred under reflux for 3 hours. After that, the reaction mixture was cooled to room temperature, and then filtered through Celite. In addition, the filtered diatomaceous earth was washed with ethyl acetate. Mix the filtrate filtered through diatomaceous earth and the washing solution of the diatomaceous earth with ethyl acetate, and concentrate un...

Synthetic example 2～3

[0279] In the "Synthesis of Dye Multimer" of Colorant Synthesis Example 1, the types and amounts of monomers used were changed as shown in Table 1, except that the polymer (A- 2)~(A-3). The obtained copolymers were used as colorants (A-2) to (A-3), respectively.

[0283] Binder resin synthesis example 1

[0284] 29 parts by mass of propylene glycol monomethyl ether acetate was put into a flask equipped with a condenser and a stirring device, and nitrogen substitution was performed. Heat to 80°C, and at the same temperature, 30.85 parts by mass of propylene glycol monomethyl ether acetate, 6.06 parts by mass (70.4 mmol) of methacrylic acid, and 16.67 parts by mass (166.5 mmol) of methyl methacrylate were added dropwise over 1 hour. A mixed solution of 15.15 parts by mass (93.4 mmol) of phenyl methacrylate and 2.27 parts by mass of 2,2′-azobis(2,4-dimethylvaleronitrile) was maintained at this temperature for 2 hours of polymerization. Thereafter...

Abstract

The invention provides a coloring composition, a coloring cured film, a colored filter, a display element and a solid camera shooting element. The coloring composition comprises a colorant, a binder resin, and a polymerizable compound; the colorant comprises at least one from a dye and a dye polymer, the dye polymer comprises a dye monomer with a dye residue and an ethylenically unsaturated group, and the dye monomer is used as a constitutional unit; the binder resin comprises a copolymer which comprises an ethylenically unsaturated monomer represented by the following formula and has a copolymerization rotio which is above 11 mol% (wherein, the dye polymer is not contained. In the formula, R1 represents a hydrogen atom or a methyl group, R2 represents a alkane with dual substituent groups whose carbon atoms are 2-4, R3 represents a substituted or unsubstituted phenyl group, a substituted or unsubstituted polycyclic aromatic hydrocarbon group, or a substituted or unsubstituted nitrogen-containing alicyclic heterocyclic group. n represents integer from 1 to 100, wherein when n is 2 or above, a plurality of R2 may be the same or different.

Description

Technical field [0001] The present invention relates to a colored composition, a colored cured film, a color filter, a display element, and a solid-state imaging element. More specifically, it relates to a color liquid crystal display element, a solid-state imaging element, and an organic EL display for forming in a transmissive or reflective type. Colored compositions of colored cured films used in devices, electronic paper, etc., colored cured films formed using the colored compositions, and color filters, display elements, and solid-state imaging elements provided with the colored cured films. Background technique [0002] When a colored radiation-sensitive composition is used to manufacture a color filter, 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 applied in a desired pattern The shape is irradiated with radiation (hereinafter referred to as "exposure") and deve...
