Description

  The present disclosure relates to a composition, a color filter, a liquid crystal display device, and a light-emitting display device.

In recent years, the market price of thin image display devices represented by displays and the like has become affordable year by year with the evolution of production technology, and the demand has increased and the production volume has increased. Reached the main stream. Recently, an organic light-emitting display device such as an organic EL display having high visibility due to self-emission has been attracting attention as a next-generation image display device. In the performance of these image display devices, further improvement in image quality such as improvement in contrast and color reproducibility and reduction in power consumption are strongly desired.
Color filters are used in these liquid crystal display devices and organic light emitting display devices. For example, in the case of a color liquid crystal display, a backlight is used as a light source, the amount of light is controlled by electrically driving the liquid crystal, and color expression is performed by the light passing through a color filter. Therefore, a color filter must be present in the color representation of a liquid crystal television and plays a major role in determining the performance of the display. In an organic light emitting display device, when a color filter is used for a white light emitting organic light emitting element, a color image is formed in the same manner as in a liquid crystal display device.

  As a recent trend, there is a demand for power saving of an image display device, and in order to improve the utilization efficiency of a backlight, an increase in luminance of a color filter is required. This is a big problem especially for mobile displays (cell phones, smartphones, tablet PCs).

Here, the color filter is generally formed on a transparent substrate, a transparent layer formed on the transparent substrate, and composed of a colored layer of three primary colors of red, green, and blue, and on the transparent substrate so as to partition each colored pattern. And a light shielding portion formed.
In such a colored layer forming method, a pigment dispersion method using a pigment having excellent heat resistance and light resistance as a coloring material has been widely used. However, with color filters using pigments, it has become difficult to achieve the current demand for higher brightness.

  As one means for achieving high brightness, coloring compositions using dyes have been studied. Dyes generally have higher transmittance than pigments and can produce high-intensity color filters, but heat resistance and light resistance are poor, and chromaticity is likely to change during high-temperature heating in the color filter production process. There was a problem. In addition, the colored resin composition using a dye has a problem that the cured film has poor solvent resistance, and the dye is transferred to a cured film that does not contain a colorant such as an adjacent pixel or protective film of another color. . Furthermore, the coloring composition used by dissolving the dye is used for color filter applications such as the problem that foreign matters are likely to be deposited on the surface of the cured coating film during the drying process, and the contrast is significantly reduced by the fluorescence emission of the dye. There were many problems.

  As a technique for improving various resistances of dyes, a technique for salting dyes is known. However, even if a salt is formed in a dye, the conventional coloring composition fades the salt-forming colorant of the dye due to high-temperature heating performed during the formation of the colored layer, and the luminance of the colored layer actually decreases. It was still difficult to achieve high brightness.

  In addition, for the formation of flattening films, protective films, spacers, interlayer insulating films, etc. for electronic components such as liquid crystal display devices, organic EL display devices, integrated circuit elements, solid-state image sensors, curable compounds and polymer compounds are used. A binder component is used. However, a binder component containing a curable compound, a polymer compound, or the like has a problem that a deterioration phenomenon such as yellowing may be observed when exposed to a high temperature during heat processing.

According to the present inventors, in Patent Document 1, a colored resin composition in which a lake pigment, a dispersant having a specific structure and an acidic organophosphorus compound, and a hindered phenol-based antioxidant are combined, It is disclosed that the coloring composition is excellent in heat resistance while using a lake pigment, suppresses fading of the colored layer due to high-temperature heating, and can form a high-luminance colored layer.
However, further improvements have been desired for the technology for suppressing the color difference before and after high-temperature heating.

It is a coloring composition that can suppress discoloration and can further suppress discoloration of the coloring material. Thus, the composition of the present disclosure can suppress color difference before and after high-temperature heating.
The reason why the composition of the present disclosure exhibits the effects as described above is estimated as follows.

[(B) Binder component]
The composition of the present disclosure contains a binder component in order to impart film formability and adhesion to the surface to be coated. In order to impart sufficient hardness to the coating film, it is preferable to contain a curable binder component. The curable binder component is not particularly limited. For example, for a colored layer of a color filter, a curable binder component used for forming a cured film for various known applications is appropriately selected according to the application. Can be used.
Examples of the curable binder component include a radiation curable binder component including a radiation curable compound that can be polymerized and cured by visible light, ultraviolet light, electron beam, and the like, and a thermosetting compound that can be polymerized and cured by heating. The thing containing the thermosetting binder component to contain can be used, These use the radiation curable binder component containing a conventionally well-known radiation curable compound and the thermosetting binder component containing a thermosetting compound suitably used. Can do.

In the case where the composition according to the present disclosure can be selectively deposited in a pattern on a substrate to form a cured film, for example, when used in an inkjet method, the curable binder component does not need developability. In this case, a known thermosetting binder component, a binder component, or the like that is used when a cured film is formed by an inkjet method or the like can be appropriately used. Moreover, also when forming the cured film which does not have a pattern shape, a well-known thermosetting binder component, a binder component, etc. can be used suitably.
As the thermosetting binder, a combination of a compound having two or more thermosetting functional groups in one molecule and a curing agent is usually used, and a catalyst capable of promoting a thermosetting reaction may be added. Examples of the thermosetting functional group include an epoxy group, an oxetanyl group, an isocyanate group, and an ethylenically unsaturated bond. An epoxy group is preferably used as the thermosetting functional group. Specific examples of the thermosetting binder component include those described in International Publication No. 2012/144521.

On the other hand, when using a photolithography process when forming a cured film, the radiation-curable binder component which has alkali developability is used suitably. In addition, you may further use a thermosetting binder component for a radiation-curable binder component.
Examples of the radiation curable binder component include a positive radiation curable binder component and a negative radiation curable binder component. Examples of the positive radiation curable binder component include a system containing an alkali-soluble resin and an o-quinonediazide group-containing compound as a radiation curable imparting component.

On the other hand, as the negative radiation curable binder component, a system containing at least an alkali-soluble resin, a polyfunctional monomer, and a radiation initiator is preferably used.
In the composition according to the present disclosure, a negative radiation curable binder component is preferable because a pattern can be easily formed using an existing process by a photolithography method.
Hereinafter, the alkali-soluble resin, the polyfunctional monomer, and the radiation initiator that constitute the negative radiation-curable binder component will be specifically described.

(Alkali-soluble resin)
The alkali-soluble resin in the present disclosure has a carboxyl group, acts as a binder resin, and is appropriately selected and used as long as it is soluble in a developer used for forming a pattern, particularly preferably an alkali developer. be able to.
A preferable alkali-soluble resin in the present disclosure is a resin having a carboxyl group, and specific examples thereof include an acrylic copolymer having a carboxyl group and an epoxy (meth) acrylate resin having a carboxyl group. Among these, particularly preferred are those having a carboxyl group in the side chain and further having a radiation polymerizable functional group such as an ethylenically unsaturated group in the side chain. It is because the film | membrane intensity | strength of the cured film formed by containing a radiation polymerizable functional group improves. These acrylic copolymers and epoxy acrylate resins may be used as a mixture of two or more.

The acrylic copolymer having a carboxyl group is obtained by copolymerizing a carboxyl group-containing ethylenically unsaturated monomer and an ethylenically unsaturated monomer.
The acrylic copolymer having a carboxyl group may further contain a structural unit having an aromatic carbocyclic ring. The aromatic carbocycle functions as a component that imparts coating properties to the composition.
The acrylic copolymer having a carboxyl group may further contain a structural unit having an ester group. The structural unit having an ester group not only functions as a component that suppresses alkali solubility of the composition, but also functions as a component that improves the solubility in a solvent and further the solvent resolubility.

Specific examples of the acrylic copolymer having a carboxyl group include those described in International Publication No. 2012/144521, specifically, for example, methyl (meth) acrylate, ethyl (meta )), Benzyl (meth) acrylate, cyclohexyl (meth) acrylate and other monomers having no carboxyl group, and (1) one or more copolymers selected from (meth) acrylic acid and anhydrides thereof. In addition, for example, a polymer having an ethylenically unsaturated bond introduced by adding an ethylenically unsaturated compound having a reactive functional group such as a glycidyl group or a hydroxyl group to the above copolymer can be exemplified, but the present invention is not limited thereto. Is not to be done.
Among these, by adding an ethylenically unsaturated compound having a glycidyl group or a hydroxyl group to the copolymer, a polymer or the like having an ethylenically unsaturated bond is polymerized with a polyfunctional monomer, which will be described later, upon irradiation with radiation. This is particularly suitable in that the cured film becomes more stable.

  The copolymerization ratio of the carboxyl group-containing ethylenically unsaturated monomer in the carboxyl group-containing copolymer is usually 5% by mass or more and 50% by mass or less, preferably 10% by mass or more and 40% by mass or less. In this case, when the copolymerization ratio of the carboxyl group-containing ethylenically unsaturated monomer is less than 5% by mass, the solubility of the resulting coating film in an alkaline developer is lowered, and pattern formation becomes difficult. On the other hand, when the copolymerization ratio exceeds 50% by mass, there is a tendency that the formed pattern is easily detached from the substrate or the pattern surface is roughened during development with an alkali developer.

  The preferred weight average molecular weight Mw of the carboxyl group-containing copolymer is preferably in the range of 1,000 to 500,000, and more preferably 3,000 to 200,000. If it is less than 1,000, the binder function after curing is remarkably lowered, and if it exceeds 500,000, pattern formation may be difficult during development with an alkaline developer.

Although it does not specifically limit as an epoxy (meth) acrylate resin which has a carboxyl group, The epoxy (meth) obtained by making the reaction material of an epoxy compound and unsaturated group containing monocarboxylic acid react with an acid anhydride. Acrylate compounds are suitable.

  Examples of the unsaturated group-containing monocarboxylic acid include (meth) acrylic acid, 2- (meth) acryloyloxyethyl succinic acid, 2- (meth) acryloyloxyethyl phthalic acid, (meth) acryloyloxyethyl hexahydrophthalic acid, (Meth) acrylic acid dimer, β-furfurylacrylic acid, β-styrylacrylic acid, cinnamic acid, crotonic acid, α-cyanocinnamic acid and the like. These unsaturated group-containing monocarboxylic acids may be used alone or in combination of two or more.

Acid anhydrides include maleic anhydride, succinic anhydride, itaconic anhydride, phthalic anhydride, tetrahydrophthalic anhydride, hexahydrophthalic anhydride, methylhexahydrophthalic anhydride, endomethylenetetrahydrophthalic anhydride, methylendo Dibasic acid anhydrides such as methylenetetrahydrophthalic acid, chlorendic anhydride, methyltetrahydrophthalic anhydride, trimellitic anhydride, pyromellitic anhydride, benzophenonetetracarboxylic dianhydride, biphenyltetracarboxylic dianhydride, biphenyl Aromatic polycarboxylic acid anhydrides such as ether tetracarboxylic acid, 5- (2,5-dioxotetrahydrofuryl) -3-methyl-3-cyclohexene-1,2-dicarboxylic acid anhydride, endobicyclo- [2 , 2,1] -Hept-5-ene-2,3-dica Polycarboxylic anhydride derivatives such as carbon anhydride, and the like. These may be used alone or in combination of two or more.
The mass average molecular weight Mw of the epoxy (meth) acrylate compound having a carboxyl group thus obtained is not particularly limited, but is preferably 1000 or more and 40000 or less, more preferably 2000 or more and 5000 or less.

  The alkali-soluble resin used in the composition of the present disclosure may be used singly or in combination of two or more, and the content thereof is 100 parts by mass of a color material contained in the composition. On the other hand, it is usually in the range of 10 to 1000 parts by mass, preferably in the range of 20 to 500 parts by mass. If the content of the alkali-soluble resin is too small, sufficient alkali developability may not be obtained, and if the content of the alkali-soluble resin is too large, the ratio of the coloring material is relatively low, which is sufficient. The coloring density may not be obtained.

(Polyfunctional monomer)
The polyfunctional monomer used in the composition of the present disclosure is not particularly limited as long as it can be polymerized by a radiation initiator described later, and a compound having two or more ethylenically unsaturated double bonds is usually used. In particular, a polyfunctional (meth) acrylate having two or more acryloyl groups or methacryloyl groups is preferable.
Such polyfunctional (meth) acrylate may be appropriately selected from conventionally known ones. Specific examples include those described in International Publication No. 2012/144521.

These polyfunctional (meth) acrylates may be used individually by 1 type, and may be used in combination of 2 or more type. In addition, when the composition of the present disclosure requires excellent radiation curability (high sensitivity), the polyfunctional monomer has three (trifunctional) or more polymerizable double bonds. Preferred are poly (meth) acrylates of trihydric or higher polyhydric alcohols and their modified dicarboxylic acids, specifically, trimethylolpropane tri (meth) acrylate, pentaerythritol tri (meth) acrylate, pentaerythritol. Succinic acid modified products of tri (meth) acrylate, pentaerythritol tetra (meth) acrylate, dipentaerythritol tetra (meth) acrylate, dipentaerythritol penta (meth) acrylate, dipentaerythritol penta (meth) acrylate Dipentaerythritol hexa (medium ) Acrylate, and the like are preferable.
The content of the polyfunctional monomer used in the composition of the present disclosure is not particularly limited, but is usually about 5 parts by mass or more and 500 parts by mass or less, preferably 20 parts by mass with respect to 100 parts by mass of the alkali-soluble resin. The range is 300 parts by mass or less. If the content of the polyfunctional monomer is less than the above range, the radiation curing does not proceed sufficiently and the irradiated part may be eluted, and if the content of the polyfunctional monomer is more than the above range, the alkali developability deteriorates. There is a fear.

(Radiation initiator)
There is no restriction | limiting in particular as a radiation initiator used in the composition of this indication, It can use combining 1 type (s) or 2 or more types from the conventionally well-known various radiation initiators. Specific examples include those described in International Publication No. 2012/144521.

It is as follows. If this content is less than the above range, the polymerization reaction cannot be sufficiently caused, so that the hardness of the cured film may not be sufficient. On the other hand, if it exceeds the above range, the solid content of the composition In some cases, the content of the coloring material or the like in the inside becomes relatively small, and a sufficient coloring density may not be obtained.

These dye salt forming colorants can be used alone or in admixture of two or more.

The salt forming color material of the dye may be a color material in which the dye forms a salt with a counter ion. Also included are organic pigments called lake pigments in which a water-soluble dye is precipitated with a rake agent (precipitating agent) to make it insoluble. Since the salt-coloring material of the dye is derived from the dye, it has a higher transmittance than a normal pigment and can form a high-luminance colored layer, but generally has a low heat resistance.
However, in the composition of the present disclosure, by containing the compound represented by the general formula (1), the amount of peroxy radicals that promote fading of the coloring material is reduced under high-temperature heating after film formation. Therefore, fading of the salt forming color material of the dye can be suppressed, and a high brightness colored layer can be formed using the salt forming color material of the dye.
