[0419] As the pigment (A1 - 2), as long as it does not contain the compound (I), known pigments can be used without particular limitation. For example, pigments classified as pigments in the Color Index (published by The Society of Dyers and Colourists) can be cited.

[0420] As pigments classified as pigments, for example, yellow pigments such as C.I. Pigment Yellow 1, 3, 12, 13, 14, 15, 16, 17, 20, 24, 31, 53, 83, 86, 93, 94, 109, 110, 117, 125, 128, 129, 137, 138, 139, 147, 148, 150, 153, 154, 166, 173, 185, 194, 214, 231, etc.;

[0421] Orange pigments such as C.I. Pigment Orange 13, 31, 36, 38, 40, 42, 43, 51, 55, 59, 61, 64, 65, 71, 73, etc.;

[0422] Red pigments such as C.I. Pigment Red 9, 97, 105, 122, 144, 166, 168, 176, 177, 180, 190, 192, 209, 215, 216, 224, 242, 254, 255, 264, 265, 266, 268, 269, 273, etc.;

[0423] Blue pigments such as C.I. Pigment Blue 15, 15:1, 15:2, 15:3, 15:4, 15:6, 16, 60, etc.;

[0424] Purple pigments such as C.I. Pigment Violet 1, 19, 23, 32, 36, 38, etc.;

[0425] Green pigments such as C.I. Pigment Green 7, 36, 58, 59, 62, 63, etc.;

[0426] Brown pigments such as C.I. Pigment Brown 23, 25, etc.;

[0427] Black pigments such as C.I. Pigment Black 1, 7, etc.

[0428] As the colorant (A1), dyes and / or pigments that are yellow, red, or green are preferred.

[0429] The colorant (A1) can be subjected to rosin treatment as needed, surface treatment using derivatives into which acidic groups or basic groups are introduced, graft treatment of the surface of the colorant (A1) using a polymer compound, etc., micronization treatment based on the sulfuric acid micronization method, etc., cleaning treatment based on an organic solvent, water, etc. for removing impurities, removal treatment of ionic impurities based on the ion exchange method, etc. The particle size of the colorant (A1) is preferably substantially uniform.

[0430] When the colorant (A) further contains a colorant (A1), the content rate of the compound (I) is, for example, 1% by mass or more, preferably 2% by mass or more, more preferably 10% by mass or more, still more preferably 25% by mass or more, and particularly preferably 50% by mass or more, relative to the total amount of the colorant (A). In addition, when the colorant (A) further contains a colorant (A1), the content rate of the compound (I) is, for example, less than 100% by mass relative to the total amount of the colorant (A).

[0431] When the colored resin composition contains a solvent (E), a colorant-containing solution containing the colorant (A) and the solvent (E) can be prepared in advance, and then the colored resin composition can be prepared using the colorant-containing solution. When the colorant (A) is insoluble in the solvent (E), for example, when the colorant (A) contains a pigment (A1-2) or the like, the colorant-containing solution can be prepared by dispersing and mixing the colorant (A) in the solvent (E). The colorant-containing solution may contain a part or all of the solvent (E) contained in the colored resin composition.

[0432] The content rate of the solid component in the colorant-containing solution is preferably 0.01% by mass to 99.99% by mass, more preferably 0.1% by mass to 99.9% by mass, still more preferably 0.1% by mass to 99% by mass, even more preferably 0.5% by mass to 90% by mass, and particularly preferably 1% by mass to 50% by mass, relative to the total amount of the colorant-containing solution.

[0433] The colorant (A) can be dispersed by containing a dispersant so that the colorant (A) is in a state of being uniformly dispersed in the solution. When two or more kinds are used in combination as the colorant (A), they can be dispersed separately or a plurality of them can be mixed and dispersed.

[0434] Dispersant (P)

[0435] As the dispersant (P), for example, surfactants and the like can be cited, and it can be any of cationic, anionic, nonionic, and amphoteric surfactants. Specifically, surfactants such as polyester-based, polyamine-based, polyurethane-based, and acrylic-based surfactants can be cited. These dispersants (P) can be used alone or in combination of two or more. When represented by a trade name as the dispersant (P), examples include KP (manufactured by Shin-Etsu Chemical Co., Ltd.), FLOWLEN (manufactured by Kyoeisha Chemical Co., Ltd.), Solsperse (registered trademark) (manufactured by ZENECA Co., Ltd.), EFKA (registered trademark) (manufactured by BASF), AJISPER (registered trademark) (manufactured by Ajinomoto Fine-Techno Co., Inc.), Disperbyk (registered trademark) (manufactured by BYK-Chemie GmbH), BYK (registered trademark) (manufactured by BYK-Chemie GmbH), etc. As the dispersant (P), the resin (B) described later can be used.

[0436] The above-mentioned dispersant (P) may have an amino group or may not have an amino group.

[0437] From the viewpoint of improving brightness and contrast, the amine value of the above-mentioned dispersant (P) is 0 mgKOH / g to 65 mgKOH / g, more preferably 1 mgKOH / g to 65 mgKOH / g, further preferably 2 mgKOH / g to 63 mgKOH / g, still further preferably 3 mgKOH / g to 61 mgKOH / g, particularly preferably 5 mgKOH / g to 61 mgKOH / g, and most preferably 7 mgKOH / g to 59 mgKOH / g. If the amine value of the dispersant (P) exceeds 65 mgKOH / g, there is a concern that the brightness and contrast may decrease.

[0438] In one aspect, from the viewpoint of further improving the contrast, the amine value of the above-mentioned dispersant (P) is preferably 15 mgKOH / g to 45 mgKOH / g, more preferably 20 mgKOH / g to 40 mgKOH / g, and further preferably 25 mgKOH / g to 35 mgKOH / g.

[0439] The amine value represents the number of milligrams of potassium hydroxide equivalent to the perchloric acid required to neutralize the amine component contained in 1 g of the sample, and can be measured, for example, according to JIS K7237.

[0440] When using the dispersant (P), the amount of use of the dispersant (solid content) is usually 1 part by mass to 10,000 parts by mass, preferably 5 parts by mass to 5,000 parts by mass, more preferably 10 parts by mass to 1,000 parts by mass, and further preferably 15 parts by mass to 800 parts by mass with respect to 100 parts by mass of the colorant (A). If the amount of use of the dispersant is within the above range, there is a tendency to obtain a more uniform dispersion state of the colorant-containing solution.

[0441] The content rate of the dispersant (P) is preferably 1% by mass to 30% by mass, more preferably 2% by mass to 25% by mass, still more preferably 3% by mass to 20% by mass, and even more preferably 5% by mass to 20% by mass with respect to the total amount of the solid components of the colored resin composition.

[0442] The content rate of the colorant (A) is preferably 0.1% by mass to 50% by mass, more preferably 0.5% by mass to 40% by mass, and still more preferably 1% by mass to 30% by mass with respect to the total amount of the solid components of the colored resin composition. When the content rate of the colorant (A) is within the above range, the color density is sufficient when a color filter is formed, and the composition can contain a required amount of the resin (B), so that a pattern with sufficient mechanical strength can be formed, which is thus preferred.

[0443] Here, the "total amount of solid components" in the present specification refers to the amount obtained by removing the content of the solvent from the total amount of the colored resin composition. The total amount of the solid components and the content of each component relative to the total amount can be measured by known analytical means such as liquid chromatography or gas chromatography, for example.

[0444] <Acid>

[0445] The colored resin composition of the present invention contains one or more acids selected from phenylphosphonic acid which may have a substituent and diphenylphosphonic acid which may have a substituent. The above acids can also form salts with the dispersant, and can stabilize the salt structure of the compound of formula (I). As a result, the brightness and contrast can be improved.

[0446] One or more of the above phenylphosphonic acid and the above diphenylphosphonic acid can be used respectively in one kind or two or more kinds.

[0447] One or more acids selected from phenylphosphonic acid which may have a substituent and diphenylphosphonic acid which may have a substituent are preferably one or more selected from the compounds represented by formula (Y) and the compounds represented by formula (Z).

[0448]

[0449] [In formula (Y), R y1 represents a hydrogen atom or a hydrocarbon group having 1 to 10 carbon atoms which may have a substituent. R y2 is selected from a halogen atom, a hydroxyl group, a substituted or unsubstituted amino group, R A , OR A , COOR B , P(O)(OR B )2, a nitro group, and a cyano group. R A represents a hydrocarbon group having 1 to 10 carbon atoms which may have a substituent. R Brepresents a hydrogen atom or a hydrocarbon group having 1 to 10 carbon atoms which may have substituents. p is 0 to 5. When p is 2 or more, R y2 may be the same or different.]

[0450]

[0451] [In formula (Z), R z1 and R z2 are each independently selected from a halogen atom, a hydroxyl group, a substituted or unsubstituted amino group, R A , OR A , COOR B , P(O)(OR B )2, a nitro group, and a cyano group. R A represents a hydrocarbon group having 1 to 10 carbon atoms which may have substituents. R B represents a hydrogen atom or a hydrocarbon group having 1 to 10 carbon atoms which may have substituents.

[0522] When the ratio of the structural units of the resin [K1] is within the above range, there is a tendency that the storage stability of the colored resin composition, the developability when forming a colored pattern, and the solvent resistance of the obtained color filter are excellent.

[0523] The resin [K1] can be produced, for example, with reference to the methods described in the literature "Experimental Methods of Polymer Synthesis" (written by Takayuki Otsu, published by Kagaku Dojin Publishing Co., Ltd., 1st edition, 1st printing, March 1, 1972) and the cited references in this literature.

[0524] Specifically, the following method can be mentioned: A predetermined amount of (a) and (b), a polymerization initiator, a solvent, etc. are charged into a reaction vessel, and an oxygen-free atmosphere is formed, for example, by replacing oxygen with nitrogen, and while stirring, heating and heat preservation are carried out. It should be noted that the polymerization initiator, solvent, etc. used here are not particularly limited, and the polymerization initiator and solvent commonly used in this field can be used. For example, as the polymerization initiator, azo compounds (2,2'-azobisisobutyronitrile, 2,2'-azobis(2,4-dimethylvaleronitrile), etc.), organic peroxides (benzoyl peroxide, etc.) can be mentioned, and as the solvent, any solvent that can dissolve each monomer can be used, and solvents such as those described later as the solvent (E) of the colored resin composition of the present invention can be mentioned.

[0525] It should be noted that for the obtained copolymer, the reaction solution can be used directly, or a concentrated or diluted solution can be used, or a substance taken out in the form of a solid (powder) by methods such as reprecipitation can be used. In particular, by using the solvent contained in the colored resin composition of the present invention as the solvent during this polymerization, the reaction solution can be directly used for preparing the colored resin composition of the present invention, so that the manufacturing process of the colored resin composition of the present invention can be simplified.

[0526] In the resin [K2], the ratio of the structural units derived from each unit among all the structural units constituting the resin [K2] is preferably such that the structural units derived from (a) are 2 to 45 mol%, the structural units derived from (b) are 2 to 95 mol%, and the structural units derived from (c) are 1 to 65 mol%. More preferably, the structural units derived from (a) are 5 to 40 mol%, the structural units derived from (b) are 5 to 80 mol%, and the structural units derived from (c) are 5 to 60 mol%.

[0527] When the ratio of the structural units of the resin [K2] is within the above range, there is a tendency that the storage stability of the colored resin composition, the developability when forming a colored pattern, and the solvent resistance, heat resistance, and mechanical strength of the obtained color filter are excellent.

[0528] The resin [K2] can be produced, for example, in the same manner as the method described for the production method of the resin [K1].

[0529] In the resin [K3], the ratio of the structural units derived from each unit among all the structural units constituting the resin [K3] is preferably such that the structural units derived from (a) are 2 to 60 mol% and the structural units derived from (c) are 40 to 98 mol%. More preferably, the structural units derived from (a) are 10 to 50 mol% and the structural units derived from (c) are 50 to 90 mol%.

[0530] The resin [K3] can be produced, for example, in the same manner as the method described for the production method of the resin [K1].

[0531] The resin [K4] can be produced by obtaining a copolymer of (a) and (c) and adding a cyclic ether having 2 to 4 carbon atoms possessed by (b) to the carboxylic acid and / or carboxylic anhydride possessed by (a).

[0532] First, a copolymer of (a) and (c) is produced in the same manner as the method described for the production method of the resin [K1]. In this case, the ratio of the structural units derived from each unit is preferably the same as the ratio cited for the resin [K3].

[0533] Next, a cyclic ether having 2 to 4 carbon atoms possessed by (b) is reacted with a part of the carboxylic acid and / or carboxylic anhydride derived from (a) in the above copolymer.

[0534] After the production of the copolymer of (a) and (c), the atmosphere in the flask is replaced from nitrogen to air, and (b), a reaction catalyst for the carboxylic acid or carboxylic anhydride and the cyclic ether (such as tris(dimethylaminomethyl)phenol, etc.) and a polymerization inhibitor (such as hydroquinone, etc.) are put into the flask. For example, it is reacted at 60 to 130 °C for 1 to 10 hours, whereby the resin [K4] can be produced.

[0535] (b) is preferably used in an amount of 5 to 80 moles, more preferably 10 to 75 moles, relative to 100 moles of (a). By being in this range, there is a tendency for good balance among the storage stability of the colored resin composition, the developability during pattern formation, and the solvent resistance, heat resistance, mechanical strength, and sensitivity of the resulting pattern. Since the cyclic ether has high reactivity and it is not easy to leave unreacted (b), (b1) is preferably used as (b) used in resin [K4], and (b1-1) is more preferably used.

[0536] The amount of the above reaction catalyst used is preferably 0.001 to 5 parts by mass relative to 100 parts by mass of the total amount of (a), (b), and (c).

[0608] When heating and drying, the temperature is preferably 30 to 120 °C, more preferably 50 °C to 110 °C. In addition, as the heating time, it is preferably 10 seconds to 60 minutes, more preferably 30 seconds to 30 minutes.

[0609] When drying under reduced pressure, it is preferably carried out at a pressure of 50 to 150 Pa in a temperature range of 20 to 25 °C.

[0610] The film thickness of the colored resin composition layer is not particularly limited and can be appropriately selected as long as it is based on the film thickness of the target color filter.

[0611] Next, the colored resin composition layer is exposed through a photomask for forming the target colored pattern. The pattern on this photomask is not particularly limited, and a pattern corresponding to the target use is used. In addition, in order to be able to uniformly irradiate parallel light on the entire exposure surface and accurately align the photomask with the substrate on which the colored resin composition layer is formed, exposure devices such as mask aligners and steppers are preferably used. In the case of forming a colored coating film, it is only necessary to expose without using a photomask.

[0612] As the light source used for exposure, a light source that preferably generates light with a wavelength of 250 to 450 nm is used. For example, light with a wavelength less than 350 nm can be cut off using a filter that cuts off this wavelength region, or light near 436 nm, near 408 nm, or near 365 nm can be selectively extracted using a band-pass filter that extracts these wavelength regions. Specifically, a mercury lamp, a light-emitting diode, a metal halide lamp, a halogen lamp, etc. can be mentioned.

[0613] The exposed colored resin composition layer is brought into contact with a developer to perform development, thereby forming a colored pattern on the substrate. By development, the unexposed portion of the colored resin composition layer dissolves in the developer and is removed. As the developer, for example, an aqueous solution of an alkaline compound such as potassium hydroxide, sodium bicarbonate, sodium carbonate, or tetramethylammonium hydroxide is preferably used. The concentration of these alkaline compounds in the aqueous solution is preferably 0.01% by mass to 10% by mass, more preferably 0.03% by mass to 5% by mass. In addition, the developer may contain a surfactant.

[0614] The development method can be any one of a paddle method, an immersion method, a spray method, etc. Further, the substrate can be tilted at an arbitrary angle during development.

[0615] The developed substrate is preferably washed with water.

[0616] In addition, it is preferable to perform post-baking on the obtained colored pattern or colored coating film. The post-baking temperature is preferably 150°C to 250°C, more preferably 160°C to 240°C. The post-baking time is preferably 1 to 120 minutes, more preferably 10 to 60 minutes.

[0617] <Display device>

[0618] The above-described color filter is useful as a color filter used in a display device (for example, a liquid crystal display device, an organic EL device, an electronic paper, etc.) and a solid-state imaging element.

[0735] <Formation of Colored Coating Film (Color Filter)>

[0736] The colored resin compositions 1 to 7 obtained in Examples 1 to 7 and the comparative colored resin compositions 1 to 4 obtained in Comparative Examples 1 to 4 were respectively coated on a 2-inch square glass substrate (EAGLE 2000; manufactured by CORNING) by spin coating, pre-baked at 100 °C for 3 minutes to form a composition layer. After cooling, an exposure machine (TME-150RSK; manufactured by TOPCON) was used, and in an atmospheric atmosphere, at 60 mJ / cm 2After irradiating the composition layer with an exposure amount (based on 365 nm), it was baked in an oven at 230 °C for 20 minutes to obtain a colored coating film.

[0737] <Evaluation of contrast>

[0738] For the obtained colored coating film, a contrast meter (CT-1; manufactured by Kamban Electric Co., Ltd., color difference meter BM-5A; manufactured by TOPCON Corporation, light source; F-10, polarizing film; manufactured by Kamban Electric Co., Ltd.) was used, and the blank value was set to 50000 to measure the contrast.

[0739] <Evaluation of brightness>

[0740] For the obtained colored coating film, a colorimeter (OSP-SP-200; manufactured by Olympus Corporation) was used to measure the spectral reflectance, and the characteristic function of the C light source was used to measure the xy chromaticity coordinates (x, y) and the stimulus value Y in the CIE XYZ colorimetric system. Y represents brightness, and the Y values at the same y coordinate were compared and evaluated. The larger Y is, the higher the brightness.

[0741] The results of the film thickness, brightness, and contrast of the colored coating films obtained in Examples 1 to 5 and Comparative Examples 1 to 2 are shown in Table 11.

[0742] [Table 11]

[0743]

[0744] The results of the film thickness, brightness, and contrast of the colored coating films obtained in Example 6 and Comparative Example 3 are shown in Table 12.

[0746]

[0747] The results of the film thickness, brightness, and contrast of the colored coating films obtained in Example 7 and Comparative Example 4 are shown in Table 13.

[0748] [Table 13]

[0749]

[0750] When the amine value of the dispersant exceeds 65 mgKOH / g, the brightness and contrast are greatly reduced (Comparative Example 2). Even when the amine value of the dispersant is 65 mgKOH / g or less, but phenylphosphoric acid is not added, although the brightness and contrast are improved, they are not sufficient (Comparative Example 1).

[0751] Comparing Examples 1 to 5, in which the amine value of the dispersant is 65 mgKOH / g or less and phenylphosphoric acid is added, with Comparative Examples 1 to 2, it can be seen that they exhibit high contrast and high brightness.

[0752] In Example 6 where the amine value of the dispersant is 65 mgKOH / g or less and diphenylphosphoric acid is added, it can be seen that a high contrast is exhibited and the brightness is also increased compared to Comparative Example 3.

[0753] In Example 7 where the amine value of the dispersant is 65 mgKOH / g or less and phenylphosphoric acid and colorant (II-3) are added, it can be seen that a high contrast is exhibited and the brightness is also increased compared to Comparative Example 4.
