The present disclosure provides a method for producing a cured product, which comprises a step of curing the composition.

According to the present disclosure, since the method for producing the cured product cures the composition, for example, a cured product that can be used as an optical filter having excellent light absorption in a desired wavelength region can be obtained. Can be done.

The present disclosure has an effect that it is possible to provide a composition capable of producing a cured product having excellent light absorption in a desired wavelength region.

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

A. Composition First, the composition of the present disclosure will be described.
The composition of the present disclosure is characterized in that it contains a dye, a cationically polymerizable component, and an acid generator.

According to the present disclosure, when the composition contains a dye, a cationically polymerizable component and an acid generator, a cured product having excellent light absorption in a desired wavelength region can be obtained.

The reason why a cured product having excellent light absorption in a desired wavelength region can be obtained by using a composition containing the above components is presumed as follows.
That is, in the composition of the present disclosure, by using the dye in combination with the above-mentioned cationically polymerizable component and the acid generator, the dye is less likely to be modified or decomposed.
More specifically, the cationically polymerizable component such as an epoxy compound has a milder curing reaction than, for example, a radically polymerizable compound such as methacrylate and acrylate, and can suppress the occurrence of modification of the dye. .. As a result, when the composition is cured, there is little decrease in the content of the dye, that is, the dye capable of absorbing light in a desired wavelength region.
Further, in the composition of the present disclosure, by using the above-mentioned cationically polymerizable component and acid generator, it is possible to maintain a state in which the dye is stably dispersed.
More specifically, cationically polymerizable components such as epoxy compounds have less curing shrinkage during curing and agglomeration of dyes during curing as compared with, for example, radically polymerizable compounds such as methacrylate and acrylate. Less is. As a result, in the cured product of the above composition, the dye is stably dispersed and retained.
As a result, the dye in the cured product can efficiently absorb light in a desired wavelength range.
From the above, when the composition contains a predetermined dye, a cationically polymerizable component, and an acid generator, a cured product having excellent light absorption in a desired wavelength region can be obtained.
In addition, the above composition makes it easy to predict the light absorption of the cured product.

In the present disclosure, for example, by using a dye having a maximum absorption wavelength of 450 nm or more and less than 550 nm, the wavelength of the overlapping region of blue light having a spectral peak near 450 nm and green light having a spectral peak near 550 nm is used. Can absorb light stably.
Thereby, by using the above composition, it is possible to obtain an optical filter capable of selectively absorbing only light having a wavelength in the overlapping region of blue light and green light.
As described above, according to the above composition, by selecting a dye having an absorption maximum in a predetermined wavelength range according to its application, it is possible to obtain an optical filter having excellent light absorption in the wavelength region. ..

Further, according to the composition of the present disclosure, the following effects are exhibited.
As described above, the cationically polymerizable component such as an epoxy compound has less curing shrinkage during polymerization as compared with a radically polymerizable compound such as acrylate.
Therefore, even when the composition is applied to a member such as a base material and then made into a cured product, curling and peeling are less likely to occur.
Further, the cationically polymerizable component has higher water resistance than, for example, a radically polymerizable compound such as acrylate, and has less decrease in adhesion in a high humidity environment, for example.
Therefore, the above composition has excellent adhesion.
From the above, by simultaneously containing a predetermined dye, a cationically polymerizable component, and an acid generator, the above composition becomes a composition capable of producing an optical filter having excellent light absorption in a desired wavelength region. At the same time, it is possible to obtain a cured product having less curl and peeling and excellent adhesion.

Further, since the above composition can be cured by cationic polymerization, the obtained cured product can be 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.
Further, since the composition contains a cationically polymerizable component such as an epoxy compound, the obtained cured product has excellent flexibility as compared with, for example, a radically polymerizable compound such as acrylate. Therefore, the optical filter manufactured by using the above composition can be particularly preferably used in, for example, an image display device that requires flexibility.

The compositions of the present disclosure include dyes, cationically polymerizable components and acid generators.
Hereinafter, each component of the composition of the present disclosure will be described in detail.

1. 1. Dye The dye has no problem as long as it can absorb light in a desired wavelength range, and can be appropriately set according to the type and use of the composition.
The maximum absorption wavelength of the dye is, for example, from the viewpoint of obtaining an optical filter having excellent light absorption in a desired wavelength region, from the viewpoint of using it in an optical filter that reduces the overlap between visible light of two types of color development, and the like. Those capable of absorbing light in the wavelength range in which the emission spectra of the two colors overlap can be used.
The maximum absorption wavelength of the dye can be, for example, 550 nm or more and 610 nm or less from the viewpoint of being used in an optical filter that reduces the overlap of green light and red light.
The dye is not limited to the overlap between visible light of 380 nm or more and 780 nm or less, but is used in an optical filter for reducing the overlap between ultraviolet light having a wavelength shorter than 380 nm and infrared light having a wavelength longer than 780 nm. Those having the maximum absorption wavelength in the wavelength range of these lights can also be used.
The maximum absorption wavelength of the dye is 450 nm or more and less than 550 nm from the viewpoint of being able to obtain a cured product having excellent light absorption in a desired wavelength region, that is, the composition of the present disclosure is a dye. It is preferable that the dye contains a cationically polymerizable component and an acid generator, and the dye has a maximum absorption wavelength of 450 nm or more and less than 550 nm.
A dye having a maximum absorption wavelength of 450 nm or more and less than 550 nm has lower stability than a dye having a maximum absorption wavelength in the vicinity of 600 nm, and is denatured / decomposed when cured by being used together with a radically polymerizable compound. It is easy to occur. Therefore, by using the above-mentioned dye, the effect that a cured product having excellent light absorption in a desired wavelength region can be obtained can be more effectively exhibited.
Further, by using a dye having a maximum absorption wavelength of 450 nm or more and less than 550 nm as the dye, the composition can be easily used for an optical filter that reduces the overlap of blue light and green light and improves the color purity. Because it becomes.

In the present disclosure, having a maximum absorption wavelength of 450 nm or more and less than 550 nm can mean that the maximum absorption wavelength in the wavelength range of 380 nm or more and 780 nm or less is included in 450 nm or more and less than 550 nm.
In the present disclosure, the maximum absorption wavelength of the dye is preferably 470 nm or more and 530 nm or less, and more preferably 480 nm or more and 510 nm or less. This is because it is easy to make the color purity of blue light and green light excellent, and further, the decrease in color intensity is small.
Further, it is possible to more effectively obtain the effect that a cured product having excellent light absorption in a desired wavelength region can be obtained.

Further, the half width of the dye (hereinafter, may be referred to as the half width of the dye alone) is not a problem as long as a cured product having excellent color reproducibility can be obtained, but it is preferably 100 nm or less. Above all, it is preferably 10 nm or more and 80 nm or less, and particularly preferably 20 nm or more and 50 nm or less.
This is because when the half-value width of the dye alone is within the above range, it is easy to make the color purity of blue light and green light excellent, and further, the decrease in color intensity is small.

There is no problem in the method for measuring the maximum absorption wavelength and the full width at half maximum as long as the maximum absorption wavelength can be measured with high accuracy. For example, the following method can be used.
(1) Dissolve the dye in a solvent to prepare a dye solution.
(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 (for example, a visible ultraviolet absorptiometer V-670 manufactured by JASCO Corporation).
There is no problem with the concentration of the dye solution as long as the maximum absorption wavelength can be confirmed accurately. For example, the transmittance at the wavelength that becomes the maximum absorption wavelength is about 5% (for example, 3% or more and 7% or less). Can be adjusted to be.
As the solvent, there is no problem as long as the dye can be dissolved, the shift of the maximum absorption wavelength is small, and the transmission spectrum of each dye can be measured accurately. For example, chloroform can be used. Further, for the dye that does not dissolve in chloroform, another solvent can be used.
As the transmission spectrum of the dye solution, the transmission spectrum of the solvent alone is measured in advance, and the transmission spectrum of the solvent is subtracted from the transmission spectrum of the dye solution to correct the transmission spectrum.
The full width at half maximum is the distance between two points located on both sides of the peak top indicating the maximum absorption wavelength (the distance between the wavelengths at which the half value represented by (transmittance at 100-λmax) / 2 is observed). Say.
Specifically, when the transmittance at the wavelength λmax, which is the maximum absorption wavelength, is 4%, the distance between wavelengths at which the transmittance is 48% is set to the half width.
When the above dyes contain two or more kinds of dyes, a dye solution is prepared using each dye.

The dye may be any dye that can obtain a cured product having excellent light absorption in a desired wavelength region. For example, cyanine dye, merocyanine dye, pyrromethene dye, azo dye, tetraazaporphyrin. Examples thereof include system dyes, xanthene dyes, and triarylmethane dyes.
In the present disclosure, it is preferable that the dye contains at least one of a pyrromethene pigment and a cyanine pigment, and in particular, it is at least one of a pyrromethene pigment and a cyanine pigment, that is, the composition of the present disclosure. It is preferable that the substance contains a dye, a cationically polymerizable component, and an acid generator, and the dye is at least one of a pyrromethene-based dye and a cyanine-based dye.
Further, in the present disclosure, it is preferable that the above-mentioned dye contains a pyrromethene-based dye.
The above-mentioned pigments, more specifically, pyrromethene-based pigments and cyanine-based pigments, and among them, pyrromethene-based pigments are liable to undergo modification / decomposition when used together with a radically polymerizable compound and cured. Therefore, by using the above-mentioned dye, the effect that a cured product having excellent light absorption in a desired wavelength region can be obtained can be more effectively exhibited.
In the present disclosure, from the viewpoint of obtaining steep optical characteristics and improving light resistance, it is preferable that the dye contains at least one of a pyrromethene dye and a cyanine dye and a tetraazaporphyrin dye. In particular, it is preferable to contain a pyrromethene-based dye and a tetraazaporphyrin-based dye.
In the present disclosure, from the viewpoint that a cured product having excellent light absorption in a desired wavelength region can be obtained, it can be easily used for an optical filter that reduces the overlap of blue light and green light and improves the color purity. From the viewpoint, the dye has a maximum absorption wavelength of 450 nm or more and less than 550 nm, and the dye having a maximum absorption wavelength of 450 nm or more and less than 550 nm is at least one of the pyromethene dye and the cyanine dye. That is, it is preferable that the dye is at least one of a pyromethene dye and a cyanine dye having a maximum absorption wavelength of 450 nm or more and less than 550 nm.
Further, in the present disclosure, from the viewpoint that a cured product having excellent light absorption in a desired wavelength region can be obtained, the overlap of blue light and green light is reduced, and the overlap of green light and red light is further reduced. From the viewpoint of facilitating use in an optical filter for reducing and improving color purity, the dyes include a dye having a maximum absorption wavelength of 450 nm or more and less than 550 nm and a dye having a maximum absorption wavelength of 550 nm or more and 610 nm or less. It is preferable to include both of these, and among them, as a dye having a maximum absorption wavelength of 450 nm or more and less than 550 nm, at least one of a pyromethene dye and a cyanine dye, and as a dye having a maximum absorption wavelength of 550 nm or more and 610 nm or less, tetra. It is preferable to include an azaporphyrin-based dye. This is because the combination of these dyes is less likely to cause aggregation and the like, and it is easy to achieve both absorption of 450 nm or more and less than 550 nm and absorption of 550 nm or more and 610 nm or less.

The pyrromethene-based dye may be any as long as it has a pyrromethene skeleton and can absorb light in a desired wavelength range, but among them, a dye represented by the following general formula (101) is preferable.
This is because the pyrromethene-based dye can more effectively exert the effect of being able to obtain a cured product having excellent light absorption in a desired wavelength region.
