TECHNICAL FIELD The present invention relates to a composition, a cured product thereof, an optical filter, and a method for producing the cured product.
The present invention will be described in detail below.

A. Composition First, the composition of the present invention will be described.
The composition of the present invention is characterized by containing a dye, a cationic polymerizable compound, and an acid generator.

In the present invention, an optical filter having a sharp absorption peak in a desired wavelength range can be obtained by including a predetermined dye, a cationic polymerizable compound, and an acid generator in the composition.

Here, the reason why it is possible to obtain an optical filter having a sharp absorption peak in a desired wavelength range by using a composition containing the above components is presumed as follows.
By using the cationically polymerizable compound and the acid generator in the composition, it is possible to keep the dye stably dispersed.
More specifically, cationically polymerizable compounds such as epoxy compounds, for example, compared to radically polymerizable compounds such as acrylates, have less curing shrinkage during curing and less defects such as pigment aggregation during curing. . As a result, the cured product of the above composition has a sharp absorption peak in the desired wavelength range, while suppressing broadening of the absorption peak of the dye.

In the present invention, by using a dye having a maximum absorption wavelength of 550 nm or more and 610 nm or less as a dye, light having a wavelength in an overlapping region of green light having a spectral peak around 550 nm and red light having a spectral peak around 610 nm. can be stably absorbed. This makes it possible to obtain an optical filter capable of selectively absorbing only the light of wavelengths in the overlapping region of green light and red light.
Thus, by using the above composition and selecting a dye having an absorption maximum in a predetermined wavelength range depending on the application, an optical filter having a steep absorption peak in the wavelength range showing the absorption maximum of the dye can be obtained. It becomes possible.

As described above, cationically polymerizable compounds such as epoxy compounds exhibit less curing shrinkage during polymerization than radically polymerizable compounds such as acrylates.
Therefore, when the above composition is applied to a member such as a base material and then cured, the composition hardly causes curling or peeling.
In addition, the cationically polymerizable compound has higher water resistance than, for example, a radically polymerizable compound such as acrylate, and the decrease in adhesive strength in a high-humidity environment, for example, is small.
For this reason, the composition has excellent adhesion.
From the above, by simultaneously containing a predetermined dye, a cationically polymerizable compound, and an acid generator, the composition has a sharp absorption peak in a desired wavelength range and an optical filter with excellent adhesion. can be manufactured.

Moreover, since the above composition can be cured by cationic polymerization, the resulting cured product is three-dimensionally crosslinked. As a result, the cured product is superior in durability, strength, etc., such as dye retention performance, as compared with, for example, a composition in which a dye is dispersed in a thermoplastic resin or the like.
Furthermore, since the composition contains a cationically polymerizable compound such as an epoxy compound, the obtained cured product has excellent flexibility compared to, for example, a radically polymerizable compound such as an acrylate. Therefore, an optical filter manufactured using the above composition can be particularly preferably used for, for example, an image display device that requires flexibility.

Each component of the composition of the present invention will be described in detail below.
1. Dye The dye may be any dye that can absorb light in a desired wavelength range, and can be appropriately selected according to the type and use of the composition.
As the dye, for example, from the viewpoint of using it for an optical filter that reduces the overlap between two kinds of colored visible light, it is possible to use a dye that can absorb light in a wavelength range where the emission spectra of two colors overlap. .
As the dye, for example, a dye having a maximum absorption wavelength of 550 nm or more and 610 nm or less can be used from the viewpoint of use in an optical filter that reduces the overlapping of green light and red light.
That is, the composition of the present invention can contain a dye having a maximum absorption wavelength of 550 nm or more and 610 nm or less, a cationic polymerizable compound, and an acid generator.
In addition, from the viewpoint of reducing overlapping of blue light and green light and using it for an optical filter that improves color purity, a dye having a maximum absorption wavelength of 450 nm or more and 550 nm or less can be used.
As the dye, for example, not only the overlap between visible light of 380 nm or more and 780 nm or less, but also the overlap between ultraviolet light with a wavelength shorter than 380 nm and infrared light with a wavelength longer than 780 nm. , those having a maximum absorption wavelength in the wavelength range of these lights can also be used.

(1) A dye having a maximum absorption wavelength of 550 nm or more and 610 nm or less The dye is a dye having a maximum absorption wavelength of 550 nm or more and 610 nm or less, so that the composition has optical properties that reduce overlapping of green light and red light. It is suitable for manufacturing filters.
In the present invention, having a maximum absorption wavelength of 550 nm or more and 610 nm or less means that the maximum absorption wavelength in the wavelength range of 450 nm or more and 700 nm or less is included in 550 nm or more and 610 nm or less.
In the present invention, the dye preferably has a maximum absorption wavelength of 570 nm or more and 605 nm or less, more preferably 580 nm or more and 600 nm or less. This is because it is easy to make the green light and the red light excellent in color purity, and furthermore, the decrease in color intensity is small.

In addition, the half-value width of the dye having a maximum absorption wavelength of 550 nm or more and 610 nm or less (hereinafter sometimes referred to as the single dye half-value width) should be such that an optical filter having excellent color reproducibility can be obtained. , is preferably 150 nm or less, more preferably 100 nm or less, still more preferably 10 nm or more and 80 nm or less, and particularly preferably 15 nm or more and 60 nm or less.
This is because when the half-value width of the single dye is within the above range, it is easy to obtain excellent color purity of green light and red light, and further, the decrease in color intensity is reduced.

The method for measuring the maximum absorption wavelength and the half-value width may be any method as long as it can measure the maximum absorption wavelength with high accuracy. For example, the following methods can be used.
(1) A dye solution is prepared by dissolving a dye in a solvent.
(2) The dye solution is filled in a quartz cell (optical path length 10 mm, thickness 1.25 mm), and the transmittance is measured using a spectrophotometer (eg, visible-ultraviolet absorbance meter V-670 manufactured by JASCO Corp.).
The concentration of the dye solution may be a concentration at which the maximum absorption wavelength can be accurately confirmed. can be adjusted to
Any solvent may be used as long as it is capable of dissolving the dyes, has little shift in the maximum absorption wavelength, and allows the transmission spectrum of each dye to be measured with high accuracy. For example, chloroform can be used. Other solvents can be used for dyes that are not soluble in chloroform.
The transmission spectrum of the dye solution is obtained by measuring the transmission spectrum of the solvent alone in advance and subtracting the transmission spectrum of the solvent from the transmission spectrum of the dye solution for correction.
Further, the half-value width is the distance between two points located on both sides of the peak top (the distance between wavelengths at which the half-value represented by (transmittance at 100-λmax)/2) is observed.
Specifically, when the transmittance at the wavelength λmax, which is the maximum absorption wavelength, is 4%, the half width is the distance between wavelengths at which the transmittance is 48%.
When the dye having a maximum absorption wavelength of 550 nm or more and 610 nm or less contains two or more compounds, a dye solution is prepared using a dye obtained by mixing these compounds at a mass ratio contained in the composition, and the measurement is performed. I do.

Examples of the dyes having a maximum absorption wavelength of 550 nm or more and 610 nm or less include cyanine dyes, merocyanine dyes, pyrromethene dyes, azo dyes, tetraazaporphyrin dyes, xanthene dyes, triarylmethane dyes, and the like. can be done.
In the present invention, from the viewpoint of having a sharp absorption peak in the range of 550 nm or more and 610 nm or less and a narrow half width of the absorption peak, the above dye is a tetraazaporphyrin dye, a triarylmethane dye, or a cyanine dye. It preferably contains a dye, and more preferably contains a tetraazaporphyrin-based dye or a triarylmethane-based dye.

(1-1) Tetraazaporphyrin dye In the present invention, the dye having a maximum absorption wavelength of 550 nm or more and 610 nm or less preferably contains a tetraazaporphyrin dye, and the tetraazaporphyrin dye has the following general formula (1 ) is preferably a compound represented by This is because the compound represented by the following general formula (1) has a sharp absorption peak in the range of 550 nm or more and 610 nm or less, and the half width of the absorption peak is narrow.
Therefore, by using a tetraazaporphyrin-based dye made of a compound represented by the following general formula (1) as the dye, the overlapping region between green light and red light is selectively absorbed, and green light and red light are absorbed. A decrease in emission intensity of each light can be suppressed. As a result, an optical filter having excellent color reproducibility can be obtained from the above composition.
In addition, the tetraazaporphyrin-based dye has heat resistance that makes it difficult to decompose even in a high-temperature environment, and it also has volatilization resistance that makes it difficult to volatilize. It is possible to stably exhibit the improvement effect of

(1) Sensitizer The composition may contain a sensitizer as the additive.
The composition has a pigment as an essential component. Therefore, when a photo-acid generator is used as the acid generator and cured by light irradiation, the irradiated light is absorbed by the dye, resulting in insufficient curing in some cases. On the other hand, by using the above sensitizer, light in a wide range of wavelengths can be efficiently absorbed, resulting in excellent curability.
As a result, the degree of freedom in selecting the photoacid generator, the cationic polymerizable compound, etc., and the degree of freedom in selecting the exposure light source are improved, making it easier to obtain a cured product with desired properties. In addition, by increasing the curing speed and improving the curability, bleeding out of the dye can be effectively suppressed, and the effect of obtaining a cured product having a sharp absorption peak in the desired wavelength range can be more effectively exhibited.

In the present invention, among others, the sensitizer is preferably an anthracene-based compound, a naphthalene-based compound, a benzoin derivative, a benzophenone derivative, a thioxanthone derivative, or a heterocyclic compound. A heterocyclic compound is preferred.
This is because when the sensitizer is the above-described compound, the acid generation efficiency of the acid generator can be efficiently improved, and as a result, the dye-containing composition can be easily cured.
In addition, the heterocyclic compound can coordinate with the acid generator and efficiently transfer energy, so that the acid generation efficiency of the acid generator can be effectively improved.
Further, the anthracene-based compound and the naphthalene-based compound absorb light of a wide range of wavelengths, and the energy can be used for the acid generation of the acid generator, so that the irradiated active energy rays can be effectively used. In addition, since the maximum absorption wavelength is short, a cured product having excellent transparency can be obtained.

For example, benzophenone derivatives and the like may contain those corresponding to radical polymerization initiators. In addition, heterocyclic compounds may include compounds corresponding to condensed ring-containing compounds.

This is because the composition has excellent curability.

The proportion of the sensitizer used relative to the cationic polymerizable compound is not particularly limited, and may be used generally in a normal proportion within a range that does not hinder the object of the present invention.
The content of the sensitizer is, for example, preferably 1 part by mass or more and 200 parts by mass or less, preferably 5 parts by mass or more and 150 parts by mass or less, relative to 100 parts by mass of the acid generator. It is preferably at least 100 parts by mass. This is because when the above-mentioned usage ratio is within the above-mentioned range, excellent curability can be obtained.

(2) Others The total content of the additives may be any as long as it is possible to obtain a cured product having a steep absorption peak in the desired wavelength range. It is preferable that it is 30 mass parts or less in a part. This is because the above composition can easily provide a cured product having a sharper absorption peak in a desired wavelength range.

5. Composition From the viewpoint of suppressing a decrease in the emission intensity of each color, it is preferable that the cured product of the composition has a narrow half-value width of an absorption peak observed in a desired wavelength range.
Therefore, the cured product selectively absorbs only the overlapping region between the two types of colored visible light, suppressing a decrease in the emission intensity of each of the two types of colored visible light, while maintaining the color purity of each color. can be improved. As a result, the composition can provide an optical filter with excellent color reproducibility.

In the composition, for example, when the dye is a dye having a maximum absorption wavelength of 550 nm or more and 610 nm or less, when the composition is made into a cured product, the absorption peak observed at 550 nm or more and 610 nm or less of the cured product. is preferably 150 nm or less, particularly preferably 120 nm or less, particularly preferably 10 nm or more and 100 nm or less, particularly preferably 15 nm or more and 80 nm or less, especially , 20 nm or more and 50 nm or less. When the half width is within the above range, it is possible to suppress the overlap of green light and red light, improve the color purity of each color, and further suppress the decrease in the emission intensity of each color, resulting in excellent color reproducibility. This is because an optical filter can be obtained.

The following method can be used for measuring the half width of the cured product.
(1) The above composition is applied to a substrate (PET film A9300 (100 μm) manufactured by Toyobo Co., Ltd.) by a bar coating method and cured to obtain an evaluation sample (substrate + cured film).
The thickness of the coating film is adjusted so that the transmittance at the maximum absorption wavelength observed in the desired wavelength range after curing is about 5% (3% or more and 7% or less).
(2) The transmittance of the obtained evaluation sample is measured using a spectrophotometer (eg, visible-ultraviolet absorbance meter V-670 manufactured by JASCO Corp.).
The wavelength range for measuring the transmittance is not a problem as long as it includes the wavelength range in which the maximum absorption wavelength and half value derived from the dye are observed. For example, the maximum absorption wavelength of the dye is 550 nm or more and 610 nm or less. In some cases, the range can be from 450 nm to 700 nm.
As for the half-value width, the same method as the method for calculating the half-value width of a single dye can be used.

As a method for curing the composition in preparing the evaluation sample, for example, the following method can be used.
(1) After coating on the substrate, the coating film is dried at 80° C. for 5 minutes to remove the solvent.
(2) When the acid generator is a photoacid generator, the coating film after drying is cured by irradiating 700 mJ/cm ² of ultraviolet rays using a high-pressure mercury lamp to obtain a sample for evaluation.
(3) When the acid generator is a thermal acid generator, the coated film after drying is subjected to heat treatment at 100° C. for 20 minutes for curing treatment to obtain an evaluation sample.

Specifically, it is preferably 50 nm or less, more preferably 30 nm or less, and particularly preferably 10 nm or less.
This is because when the difference is within the above range, it becomes easier for the composition to obtain a cured product having a steeper absorption peak in the desired wavelength range. Therefore, the above composition can easily produce an optical filter having excellent color reproducibility.

For example, when a dye having a maximum absorption wavelength of 550 nm or more and 610 nm or less is used as the dye, the half value width of the absorption peak observed at 550 nm or more and 610 nm or less of the cured product of the composition (cured product half value width) and the absolute value of the difference (half width of the cured product - half width of the dye alone) of the absorption peak observed at 550 nm or more and 610 nm or less of the dye alone (half value width of the dye alone) is 50 nm or less. is preferable, and 30 nm or less is particularly preferable, and 10 nm or less is particularly preferable.
This is because when the difference is within the above range, it becomes easy for the composition to obtain a cured product having a steeper absorption peak in the wavelength range of 550 nm or more and 610 nm or less. Therefore, the above composition can easily produce an optical filter having excellent color reproducibility.
