[0045] Advantages of the Invention

[0046] The present invention has the effect of being able to provide a composition that can be used to manufacture a cured product having excellent temporal stability of light absorption using a cationically polymerizable component. Detailed Description of the Invention

[0047] First, the composition of the present invention will be described in detail.

[0048] A. Composition

[0049] The composition of the present invention contains a dye and a cationic polymerizable component, and the cationic polymerizable component contains an epoxy compound having a polycyclic aliphatic structure and an alicyclic epoxy compound.

[0050] The inventors of the present invention have found through research that in the case of forming an optical filter using a radical polymerizable coloring composition containing a dye as a colorant, there is sometimes a problem that an optical filter excellent in light absorbency in a desired wavelength region cannot be obtained.

[0051] Moreover, it has been found that by using a cationic polymerizable compound as a curable compound, a cured product excellent in light absorbency in a desired wavelength region can be obtained, and it was filed before the filing of the present application.

[0052] However, as a result of further research by the inventors of the present invention, it has been found that in the case of using a cured product formed by a cationic polymerizable compound, there is sometimes a problem that the light absorbency changes over time. Moreover, as a result of further in-depth research, it has been found that by containing a dye and a cationic polymerizable component containing an epoxy compound having a polycyclic aliphatic structure and an alicyclic epoxy compound, a cured product excellent in the temporal stability of light absorbency can be obtained.

[0053] Regarding the reason why the temporal stability of light absorbency can be obtained by a specific polymerizable component, the inventors of the present invention consider as follows.

[0054] Cationic polymerizable components such as epoxy compounds have a milder curing reaction compared to radical polymerizable compounds such as methacrylates and acrylates, and can suppress the generation of modification in dyes during curing. In particular, the inventors of the present invention have found through research that by using a combination of two specific cationic polymerizable components, the inhibitory effect on the modification of dyes and the like is excellent. As a result, when the composition is cured, the content of the dye, that is, the dye that can absorb light in the desired wavelength region, hardly decreases over time. The reason for this is considered in detail as follows.

[0055] That is, the above two specific cationic polymerizable components can obtain a cured product with less curing shrinkage by containing a ring structure. In particular, an epoxy compound having a polycyclic aliphatic structure can effectively suppress curing shrinkage due to the steric hindrance generated by the polycyclic aliphatic structure. In addition, an epoxy compound having a polycyclic aliphatic structure can effectively block the intrusion of moisture into the cured product through the polycyclic aliphatic structure. In particular, even under high-temperature and high-humidity conditions, it can effectively block the intrusion of moisture into the cured product. As a result, the above composition becomes a composition of a cured product in which the dye is easily stably held, the bleeding of the dye is less, and in addition, the decomposition or modification of the dye caused by the influence of the intruded moisture can be suppressed.

[0056] In addition, the alicyclic epoxy compound has excellent curability, and polymerization can be efficiently carried out between alicyclic epoxy compounds and between an alicyclic epoxy compound and an epoxy compound having a polycyclic aliphatic structure. As a result, the above composition becomes a composition that easily forms a cured product in which the dye is stably held and the bleeding of the dye is small, and it becomes easy to sufficiently carry out polymerization, so that the intrusion of moisture into the cured product can be effectively blocked, and the decomposition or modification of the dye can be suppressed.

[0057] According to the above content, a composition in which two specific cationic polymerizable components are used in combination can obtain a cured product having excellent light absorbency in a desired wavelength region, and the temporal stability of the light absorbency becomes excellent.

[0058] In addition, in the composition of the present invention, by using a cationic polymerizable component containing a specific component, the state in which the dye is stably dispersed can be maintained, which is therefore preferable. A cationic polymerizable component containing two specific epoxy compounds has less curing shrinkage during curing compared to radical polymerizable compounds such as methacrylate and acrylate, and there are fewer adverse conditions such as dye aggregation during curing. As a result, the cured product of the above composition becomes a cured product in which the dye is stably dispersed and held. As a result, the dye in the above cured product can effectively absorb light in a desired wavelength range.

[0059] According to the above content, in addition to obtaining a cured product having excellent temporal stability of light absorbency, the prediction of the light absorbency of the cured product also becomes easy for the composition of the present invention.

[0060] The composition according to the present invention further exhibits the following effects.

[0061] The cationic polymerizable component containing two specific epoxy compounds has less curing shrinkage during polymerization as described above. Therefore, even when the above composition is formed into a cured product after being coated on a member such as a substrate, the generation of curling and further the generation of peeling are reduced.

[0062] In addition, the above composition can be cured by cationic polymerization, and the obtained cured product can be made into a three-dimensionally crosslinked cured product. As a result, the above cured product becomes a cured product having excellent durability such as dye retention performance and strength compared to, for example, a composition obtained by dispersing a dye in a thermoplastic resin.

[0063] Furthermore, the cured product obtained from the above composition becomes a cured product having excellent flexibility compared to radical polymerizable compounds such as 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.

[0064] According to the above content, by using a composition containing a specified dye and two specific cationic polymerizable components, the composition can form a cured product with excellent photoabsorbing stability over time, and can obtain a cured product with particularly excellent photoabsorbing properties in the desired wavelength region, less curling and peeling, and excellent adhesion and flexibility.

[0065] Hereinafter, each component contained in the composition of the present invention will be described in detail.

[0066] 1. Cationic polymerizable component

[0067] The cationic polymerizable component refers to a compound that undergoes polymerization or crosslinking reaction by an acid. As this component, in the present invention, an epoxy compound having a polycyclic aliphatic structure and an alicyclic epoxy compound are contained.

[0068] (1) Epoxy compound (A) having a polycyclic aliphatic structure

[0069] The polycyclic aliphatic structure refers to a condensed ring composed only of aliphatic rings. Specifically, it refers to a structure in which two or more aliphatic rings are condensed without including an aromatic ring.

[0070] The polycyclic aliphatic structure can be either a saturated polycyclic aliphatic structure or an unsaturated polycyclic aliphatic structure.

[0071] Examples of the saturated polycyclic aliphatic structure include a camphane ring, an adamantane ring, a norbornane ring, a bicyclo[2.1.0]pentane ring, a bicyclo[2.1.1]hexane ring, a bicyclo[2.2.0]hexane ring, a bicyclo[3.1.0]hexane ring, a norpinane ring, a norcarane ring, a bicyclo[2.2.2]octane ring, a bicyclo[3.2.1]octane ring, a bicyclo[3.3.0]octane ring, a bicyclo[4.2.0]octane ring, a bicyclo[5.1.0]octane ring, a bicyclo[4.3.0]nonane ring, a bicyclo[3.3.1]nonane ring, a bicyclo[4.3.1]decane ring, a tricyclo[5.2.1.0 2,6 decane ring (also called tetrahydrodicyclopentadiene ring).

[0072] Examples of the unsaturated polycyclic aliphatic structure include a norbornene ring, a dicyclopentadiene ring, a bicyclo[2.2.2]oct-2-ene ring.

[0073] As the polycyclic aliphatic structure, from the aspects that the modification inhibition of the dye becomes easier, it is easy to form a cured product with excellent photoabsorbing stability over time, and it is easy to obtain a cured product with excellent photoabsorbing properties in the desired wavelength region, a saturated polycyclic aliphatic structure is preferred.

[0074] The polycyclic aliphatic structure may also contain heteroatoms in the ring-forming atoms, but from the aspect of easily obtaining a cured product with excellent light absorbability in the desired wavelength region, having less reaction with dyes and being easy to suppress modification of dyes, and easily forming a cured product with excellent temporal stability of light absorbability, it is preferably free of heteroatoms.

[0075] The polycyclic aliphatic structure may be any of bicyclic, tricyclic, and tetracyclic or higher, but is particularly preferably tricyclic or bicyclic, and especially preferably tricyclic. This is because the above composition becomes a composition having an excellent balance between the effect of obtaining a cured product with excellent temporal stability of light absorbability and curability.

[0076] It should be noted that the so-called bicyclic refers to a cyclic structure having two rings, and also includes a cyclic structure in which two rings share two or more atoms such as a bicyclo[2.1.0]pentane ring and a norbornane ring, and a structure in which two rings are bonded through one atom such as a spiro ring structure.

[0077] In addition, the so-called tricyclic refers to a cyclic structure having three rings, and examples thereof include a cyclic structure in which two or more atoms are shared between one ring of the bicyclic structure and the third ring.

[0078] The number of carbon atoms constituting the polycyclic aliphatic structure is not particularly limited, but is preferably 7 or more and 12 or less, and more preferably 9 or more and 11 or less. This is because the above composition becomes a composition having an excellent balance between the effect of obtaining a cured product with excellent temporal stability of light absorbability and curability. It should be noted that the number of carbon atoms constituting the polycyclic aliphatic structure represents the number of carbon atoms forming the polycyclic aliphatic ring skeleton, and does not include the number of carbon atoms of substituents.

[0079] As the polycyclic aliphatic structure, a tricyclo[5.2.1.0 2,6 decane ring structure is preferred from the aspect of the balance between the effect of obtaining a cured product with excellent temporal stability of light absorbability and curability, and specifically, the structure represented by the following formula (I) can be cited.

[0080] [Chemical formula 4]

[0081]

[0082] (In the formula, the polycyclic aliphatic structure means bonding to an adjacent group at the * part.)

[0083] The epoxy compound (A) having a polycyclic aliphatic structure may contain only one polycyclic aliphatic structure, or may contain two or more, but is preferably one. This is because the above composition becomes a composition having an excellent balance between the effect of obtaining a cured product with excellent temporal stability of light absorbability and curability.

[0084] In addition, from the aspect of easily obtaining a cured product with more excellent temporal stability of light absorption, the epoxy compound (A) is preferably a compound having a polycyclic aliphatic structure in its main chain.

[0085] It should be noted that the compound having a polycyclic aliphatic structure in its main chain can be set as a compound in which two or more epoxy groups are bonded to the polycyclic aliphatic structure via an ether structure. The so-called ether structure means a structure containing an ether group.

[0086] One or more hydrogen atoms on the ring in the polycyclic aliphatic structure may be substituted by a substituent.

[0087] Examples of the substituent include a hydrocarbon group having 1 to 30 carbon atoms which may have a substituent, a group having 2 to 30 carbon atoms containing a heterocycle which may have a substituent, a group obtained by substituting a methylene group in the hydrocarbon group or the group having 2 to 30 carbon atoms with a divalent group selected from the following Group I under the condition that oxygen atoms are not adjacent, an amino group, or a halogen atom.

[0088] Examples of the substituent for substituting one or more hydrogen atoms in the above hydrocarbon group or the group having 2 to 30 carbon atoms or the group obtained by substituting a methylene group in these groups with a divalent group selected from the following Group I include a halogen atom, a nitro group, a cyano group, a hydroxyl group, an amino group, a carboxyl group, a methacryloyl group, an acryloyl group, an epoxy group, a vinyl group, a vinyl ether group, a mercapto group, or an isocyanate group.

[0089] Group I: -O-, -CO-, -COO-, -OCO-, -NR 10 -, -NR 10 CO-, -S-, -CS-, -SO2-, -SCO-, -COS-, -OCS-, CSO- or a group formed by combining these groups under the condition that oxygen atoms are not adjacent.

[0090] R 10 represents a hydrogen atom or an unsubstituted hydrocarbon group having 1 to 30 carbon atoms.

[0091] It should be noted that in this specification, when a hydrogen atom in a group having a specified number of carbon atoms is substituted by a substituent containing a carbon atom, it is set to satisfy the specification including the carbon atom of the substituent. Therefore, when a hydrogen atom in a hydrocarbon group having 1 to 30 carbon atoms is substituted by a substituent, the number of carbon atoms of 1 to 30 means the number of carbon atoms after the hydrogen atom is substituted, and does not mean the number of carbon atoms of the group before the hydrogen atom is substituted.

[0092] In addition, the stipulation of the number of carbon atoms for a group obtained by substituting a methylene group in a group having a specified number of carbon atoms with a divalent group is set to be the same as the stipulation of the number of carbon atoms contained in the group before substitution. Therefore, the number of carbon atoms of a group obtained by substituting a methylene group in a hydrocarbon group having 1 to 30 carbon atoms with a divalent group is set to 1 to 30.

[0093] As the hydrocarbon group having 1 to 30 carbon atoms that can substitute a hydrogen atom on the ring of the polycyclic aliphatic structure and R in the above Group I 10 The hydrocarbon group having 1 to 30 carbon atoms represented, as long as it is a hydrocarbon group without a heterocyclic structure, examples thereof include linear or branched chain alkyl groups having 1 to 30 carbon atoms, alkenyl groups having 2 to 30 carbon atoms, cycloalkyl groups having 3 to 30 carbon atoms, and cycloalkylalkyl groups having 4 to 30 carbon atoms, etc., aliphatic hydrocarbon groups, aryl groups having 6 to 30 carbon atoms, and arylalkyl groups having 7 to 30 carbon atoms, etc., aromatic hydrocarbon groups.

[0113] The amino group that can substitute the hydrogen atom on the ring of the polycyclic aliphatic structure or the hydrogen atom in the substituent of the hydrogen atom can be any of a primary amino group, a secondary amino group, and a tertiary amino group.

[0114] As the secondary amino group and the tertiary amino group, groups obtained by substituting 1 or 2 hydrogen atoms of the primary amino group (-NH2) with a hydrocarbon group having 1 to 30 carbon atoms can be exemplified respectively. As the hydrocarbon group having 1 to 30 carbon atoms, the hydrocarbon groups exemplified above as the group that can substitute the hydrogen atom on the ring of the polycyclic aliphatic structure can be used.

[0117] From the viewpoints of ease of acquisition and easily obtaining a cured product having excellent temporal stability of light absorption, the polycyclic aliphatic structure preferably has a structure in which the hydrogen atom on the ring is not substituted by a substituent, or a structure in which the substituent is a hydrocarbon group having 1 to 10 carbon atoms or a halogen atom when substituted. From the same viewpoints, it is more preferably that the hydrogen atom on the ring is not substituted by a substituent, or the substituent is a hydrocarbon group having 1 to 5 carbon atoms or a halogen atom when substituted, particularly preferably that the hydrogen atom on the ring is not substituted by a substituent, or the substituent is an alkyl group having 1 to 5 carbon atoms or a halogen atom when substituted, and most preferably that the hydrogen atom on the ring is not substituted by a substituent, or the substituent is a methyl group or a halogen atom when substituted. This is because it is easy to form a cured product having excellent temporal stability of light absorption and the ease of acquisition is excellent.

[0118] The number of polycyclic aliphatic structures or the linking structure between the epoxy group and the polycyclic aliphatic structure in the epoxy compound (A) having a polycyclic aliphatic structure can be any number or linking structure. The epoxy compound (A) having a polycyclic aliphatic structure may also be a monofunctional epoxy compound, but from the aspect of easily obtaining a composition with an excellent balance between the effect of a cured product having excellent light absorptivity over time and curability, a polyfunctional epoxy compound is preferred. Further preferably, it is a compound having 2 or more and 4 or less functional groups, and more preferably a compound having 2 or more and 3 or less functional groups. In particular, the epoxy compound (A) being a compound having a glycidyl ether group is preferred from the aspect of easily obtaining a composition with an excellent balance between the effect of a cured product having excellent light absorptivity over time and curability. Particularly preferably, it is a compound obtained by directly bonding 1 or more glycidyl ether groups to the polycyclic aliphatic structure, and most preferably a compound obtained by directly bonding 2 or more glycidyl ether groups to the polycyclic aliphatic structure. This is because such a compound easily obtains a cured product having excellent light absorptivity over time, and is also easy to obtain.

[0120] The epoxy compound (A) having a polycyclic aliphatic structure is further preferably an aliphatic epoxy compound having a polycyclic aliphatic structure from the viewpoint of the balance between the effect of a cured product having excellent light absorptivity over time and curability. In this specification, an aliphatic epoxy compound refers to an epoxy compound having an aliphatic group but not having an aromatic group and not having a cycloalkyl epoxy group. It should be noted that the reason why a cured product having excellent light absorptivity over time and an excellent balance of curability can be obtained by the epoxy compound (A) being an aliphatic epoxy compound and a cured product having excellent light absorptivity in a desired wavelength region can be more easily obtained is not clear, but it is presumed that because it does not have an aromatic group, stacking between aromatic groups can be effectively suppressed, and curing shrinkage and the like can be more effectively suppressed.

[0121] The preferred constitution of the epoxy compound (A) having a polycyclic aliphatic structure will be described more specifically below.

[0122] From the viewpoint of achieving a composition that provides a cured product with excellent light absorbency and excellent balance between the effects of long-term stability and curability, the epoxy compound (A) having a polycyclic aliphatic structure is preferably represented by the following formula (II) or formula (III), and more preferably by formula (II).

[0195] Among them, the aromatic epoxy compound (C2) is preferably a monofunctional aromatic epoxy compound having 1 epoxy group such as glycidyl ether of monofunctional phenols, and particularly preferably glycidyl ether of monofunctional phenols. This is because it becomes easy to form a cured product with excellent light absorption and excellent stability over time. In addition, since the viscosity can be easily adjusted, it is easy to prepare a composition with excellent coatability.

[0196] The content of the aromatic epoxy compound not having the above polycyclic aliphatic structure may be an amount that can obtain a cured product with excellent light absorption and excellent stability over time. However, for example, in the case of containing an aromatic epoxy compound, it can be set to 0.5 parts by mass or more and 20 parts by mass or less in 100 parts by mass of the above cationic polymerizable component, and preferably 1 part by mass or more and 20 parts by mass or less.

[0199] As the above cationic polymerizable component, other compounds such as episulfide compounds and sulfidocyclopropane compounds can be used.

This is because a cured product having excellent temporal stability of light absorption and good adhesion to a substrate can be obtained. In addition, a cured product having a steeper absorption peak in a desired wavelength range can be obtained. In the present invention, the total content of the epoxy compound (A) having a polycyclic aliphatic structure and the alicyclic epoxy compound (B) is preferably 99 parts by mass or less, preferably 98 parts by mass or less, and preferably 95 parts by mass or less in 100 parts by mass of the cationically polymerizable component.

[0203] The cationically polymerizable component in the present invention may be any component that can obtain a cured product having excellent temporal stability of light absorption, and for example, either a low molecular weight compound or a high molecular weight compound can be used.

[0204] From the viewpoints such as the coatability of the composition, the above cationically polymerizable component preferably contains a low molecular weight compound. In addition, since the dispersibility or solubility of the low molecular weight compound in the composition is excellent, a cured product having excellent transparency can be obtained.

[0205] Regarding the molecular weight of the above low molecular weight compound, as long as it is a molecular weight that can obtain a desired coatability or the like, it can be set to 1,000 or less, preferably 50 or more and 500 or less, and preferably 50 or more and 300 or less.

[0206] It should be noted that hereinafter, when the compound is a polymer, the molecular weight represents the weight average molecular weight (Mw).

[0207] In addition, the weight average molecular weight can be determined by gel permeation chromatography (GPC) as a standard polystyrene conversion value.

[0208] The weight-average molecular weight Mw can be obtained, for example, by using GPC (LC-2000plus series) manufactured by JASCO Corporation, setting the elution solvent to tetrahydrofuran, setting the calibration curve with polystyrene standards to Mw 1110000, 707000, 397000, 189000, 98900, 37200, 13700, 9490, 5430, 3120, 1010, 589 (TSKgel standard polystyrene manufactured by Tosoh Corporation), and setting the measurement columns to KF-804, KF-803, KF-802 (manufactured by Showa Denko K.K.) for measurement.

[0209] In addition, the measurement temperature can be set to 40 °C, and the flow rate can be set to 1.0 mL / minute.

[0210] As the sample concentration during measurement, it can be set to 0.1 mass% to 0.2 mass%.

[0211] The content of the above-mentioned low-molecular-weight compound only needs to be the content that can obtain a cured product with excellent temporal stability of light absorbency. For example, in 100 parts by mass of the cationic polymerizable component, it is preferably 10 parts by mass or more, more preferably 30 parts by mass or more, particularly more preferably 50 parts by mass or more, and particularly preferably 60 parts by mass or more and 99 parts by mass or less. This is because when the content is within the above range, the above composition easily forms a cured product with excellent temporal stability of light absorbency.

[0212] The content of the above-mentioned cationic polymerizable component in the composition of the present invention is not a problem as long as it is an amount that can obtain a cured product with excellent temporal stability of light absorbency. For example, in 100 parts by mass of the solid content of the above composition, it can be set to 50 parts by mass or more, preferably 50 parts by mass or more and 99 parts by mass or less, more preferably 70 parts by mass or more and 96 parts by mass or less, and more preferably 85 parts by mass or more and 95 parts by mass or less. This is because when the content is within the above range, the above composition easily forms a cured product with excellent temporal stability of light absorbency.

[0213] It should be noted that the solid content includes all components except the solvent.

[0214] 2. Dye

[0215] The dyes in the present invention are preferably cationic dyes in terms of effectively obtaining the effect of being able to produce a cured product with excellent long-term stability of light absorption, and having excellent light transmittance in wavelength regions other than the specified wavelength region, and being suitable for use in optical filters. As the cationic dye, any dye that can obtain a cured product with excellent long-term stability of light absorption can be used. For example, cyanine dyes, merocyanine dyes, pyrromethene dyes, azo dyes, tetraazaporphyrin dyes, xanthene dyes, triarylmethane dyes, etc. can be cited. As the above dyes, for example, from the viewpoint of an optical filter for reducing the overlap between the visible lights of two colors, etc., a dye that can absorb light in the wavelength range where the emission spectra of two colors overlap is preferably used.

[0216] In the present invention, the above dye preferably contains at least one of a pyrromethene dye and a tetraazaporphyrin dye. This is because these dyes are easily modified in the presence of moisture or the like, and can effectively exhibit the effect of being able to obtain a cured product with excellent long-term stability of light absorption.

[0217] In addition, in the present invention, from the aspect of being easily used for an optical filter for reducing the overlap between blue light and green light and improving color purity, at least one of dyes having a maximum absorption wavelength of 450 nm or more and less than 550 nm is preferably used. In the present invention, as the dye having a maximum absorption wavelength of 450 nm or more and less than 550 nm, a pyrromethene dye is preferably used. In addition, in the present invention, from the viewpoint of being easily used for an optical filter for reducing the overlap between green light and red light and improving color purity, at least one of dyes having a maximum absorption wavelength of 550 nm or more and 610 nm or less is preferably used. As the dye having a maximum absorption wavelength of 550 nm or more and 610 nm or less, a tetraazaporphyrin dye is preferably used. For the above reasons, in the present invention, as the dye, at least one of a pyrromethene dye and a tetraazaporphyrin dye is also preferably contained, and particularly preferably both dyes are contained.

[0218] There is no problem with the method for measuring the above maximum absorption wavelength as long as it can accurately measure the maximum absorption wavelength. For example, the following method can be used.

[0219] (1) Dissolve the dye in a solvent to prepare a dye solution.

[0220] (2) Fill the dye solution into a quartz cell (optical path length: 10 mm, thickness: 1.25 mm), and use a spectrophotometer (for example, visible ultraviolet spectrophotometer V-670 manufactured by JASCO Corporation, etc.) to measure the transmittance.

[0221] It should be noted that the concentration of the dye solution is not a problem as long as it can accurately confirm the maximum absorption wavelength. For example, it can be adjusted so that the transmittance at the wavelength corresponding to the maximum absorption wavelength is about 5% (for example, 3% or more and 7% or less).

[0222] As the above-mentioned solvent, any solvent that can dissolve the dye, has little displacement of the maximum absorption wavelength, and can accurately measure the transmission spectrum of each dye is acceptable. For example, chloroform can be used. In addition, for dyes that are insoluble in chloroform, other solvents can be used.

[0223] The transmission spectrum of the dye solution uses the spectrum corrected by pre-measuring the transmission spectrum of the solvent monomer and subtracting the transmission spectrum of the solvent from the transmission spectrum of the dye solution.

[0224] In addition, the full width at half maximum refers to the distance between two points on both sides of the peak top showing the maximum absorption wavelength (the distance between the wavelengths at which the half value represented by (100 - transmittance at λmax) / 2 is observed).

[0225] Specifically, when the transmittance at the wavelength λmax corresponding to the maximum absorption wavelength is 4%, the distance between the wavelengths when the transmittance becomes 48% is set as the full width at half maximum.

[0226] When the above-mentioned dye contains two or more dyes, dye solutions are prepared using each dye.

[0228] The above-mentioned pyrromethene dyes are compounds that have a pyrromethene skeleton and can absorb light in the desired wavelength range. For example, the compound represented by formula (2) described in JP-A-2013-109105 can be used.

[0229] As the above-mentioned pyrromethene dyes, from the viewpoints of excellent dispersion stability and easy formation of a cured product having excellent light absorbency in the wavelength region of 450 nm or more and less than 550 nm, a dipyrromethene complex compound obtained by coordinating a compound represented by the following formula (11) with a metal atom or a metal compound can be preferably used.

Any of the following-described preferred constitutions can also be arbitrarily combined in multiple. In addition, since a cured product having excellent light absorption in the wavelength region of 450 nm or more and less than 550 nm can be more easily obtained, it is preferable.

[0349] From the viewpoint of obtaining a cured product having more excellent temporal stability of light absorption, the content of the above-mentioned dye is preferably 0.5 part by mass or more and 4.5 parts by mass or less, preferably 1 part by mass or more and 4 parts by mass or less, and preferably 1.5 part by mass or more and 4 parts by mass or less in 100 parts by mass of the solid content of the composition.

[0350] It should be noted that when the dye contains two or more dyes, the content of the above-mentioned dye refers to the total content of the dyes.

[0351] The content of the above dye is not a problem as long as it is an amount that can obtain a cured product with excellent temporal stability of light absorbency, and it is appropriately set according to the use of the above composition, etc. However, relative to 100 parts by mass of the cationic polymerizable component, it can be set to 0.01 part by mass or more and 10 parts by mass or less, preferably 0.02 part by mass or more and 5 parts by mass or less, particularly preferably 0.05 part by mass or more and 5 parts by mass or less, among which particularly preferably 0.1 part by mass or more and 4.5 parts by mass or less, among which particularly preferably 0.5 part by mass or more and 4.5 parts by mass or less, preferably 0.8 part by mass or more and 4.5 parts by mass or less, preferably 1.0 part by mass or more and 4.5 parts by mass or less, preferably 1.5 part by mass or more and 4.2 parts by mass or less.

[0352] 3. Acid generator

[0353] The composition of the present invention preferably contains an acid generator. This is because by containing an acid generator, the above composition becomes a composition that easily undergoes cationic curing.

[0354] As the above acid generator, any compound is acceptable as long as it is a compound that can generate an acid under specified conditions, and there is no particular limitation.

[0355] As such an acid generator, for example, a photoacid generator that can generate an acid by light irradiation such as ultraviolet irradiation, and a thermal acid generator that can generate an acid by heat can be used.

[0356] The above acid generator can use at least one of the above photoacid generator and thermal acid generator. From the viewpoints of easy curing, reducing thermal damage to surrounding components used adjacent to the composition during curing of the composition, and a higher degree of freedom in the selection of surrounding components, etc., a photoacid generator is preferred. In addition, the above photoacid generator also has the advantage of a fast curing rate.

[0357] In addition, from the viewpoint of making it easier to form a cured product even in a part where light hardly reaches, the above acid generator is preferably a thermal acid generator. In addition, since the curing rate of the above thermal acid generator is relatively slow, after curing treatment (heating treatment) using it, it is possible to easily bond with other components.

[0358] The content of the above acid generator can be set to 0.01 part by mass or more and 10 parts by mass or less, preferably 0.1 part by mass or more and 5 parts by mass or less, in 100 parts by mass of the solid content of the above composition in total for single or multiple types. This is because the above composition can easily obtain a cured product with excellent temporal stability of light absorbency.

[0359] The usage ratio of the acid generator relative to the above cationic polymerizable component is not particularly limited, and it may be used at a generally usual usage ratio as long as it does not hinder the object of the present invention. For example, relative to 100 parts by mass of the cationic polymerizable component, the acid generator is preferably 0.05 parts by mass or more and 10 parts by mass or less, preferably 0.5 parts by mass or more and 8 parts by mass or less, preferably 1 part by mass or more and 7 parts by mass or less, and preferably 1.5 parts by mass or more and 5 parts by mass or less. With the above usage ratio within the above range, it is suitable in terms of sufficiently curing the cationic polymerizable component and having good heat resistance of the cured product of the composition.

[0360] In addition, this is because the above composition can easily obtain a cured product with excellent temporal stability of light absorption.

[0361] (1) Photoacid generator

[0362] As the above photoacid generator, any compound can be used as long as it can generate an acid by light irradiation such as ultraviolet irradiation, and it is preferably an onium salt or a derivative thereof that releases a Lewis acid by ultraviolet irradiation. Representative examples of such compounds include salts of cations and anions represented by the following formula (21).

In addition, at least one is preferably the above organic group having an aromatic ring. Q is an atom or atomic group selected from the group consisting of S, N, Se, Te, P, As, Sb, Bi, O, I, Br, Cl, F, N=N. In addition, when the valence of Q in the cation [A] m+ is set to q, the relationship m = a - q needs to hold (where N=N is treated with a valence of 0).

[0369] In addition, the anion [B] m- is preferably a halide complex, and its structure can be represented, for example, by the following formula (23).

In addition, when the valence of L in the anion [B] m- is set to p, the relationship of m = b - p needs to hold.

[0373] As the anion [LX 2 b m- in the above formula, specific examples include tetrakis(pentafluorophenyl)borate [(C6F5)4B] - , tetrafluoroborate (BF4) - , hexafluorophosphate (PF6) - , hexafluoroantimonate (SbF6) - , hexafluoroarsenate (AsF6) - , hexachloroantimonate (SbCl6) - , tris(pentafluoromethyl)trifluorophosphate ion (FAP anion), etc.

[0374] In addition, for the anion [B] m- , an anion having the structure represented by the following formula (24) can also be preferably used.

[0375] [Chemical formula 18]

[0376] [LX 2 b-1 (OH)] m- (24)

[0378] In the present invention, among such onium salts, it is particularly effective to use the following aromatic onium salts (1) to (3). One kind can be used alone from them, or two or more kinds can be used in combination.

[0379] (1) Aryldiazonium salts such as phenyl diazonium hexafluorophosphate, 4-methoxyphenyl diazonium hexafluoroantimonate, 4-methylphenyl diazonium hexafluorophosphate

[0388] In addition, as other preferred examples, (η 5 -2,4-cyclopentadien-1-yl)[(1,2,3,4,5,6-η)-(1-methylethyl)benzene]-iron-hexafluorophosphate and other iron-arene complexes, mixtures of aluminum complexes such as tris(acetylacetone)aluminum, tris(ethylacetoacetato)aluminum, tris(salicylaldehyde)aluminum and silanol compounds such as triphenylsilanol, etc. can also be cited.

[0389] Among them, from the viewpoints of practicality and photosensitivity, it is preferable to use aromatic iodonium salts, aromatic sulfonium salts, and iron-arene complexes. In particular, aromatic sulfonium salts are further preferred from the viewpoint of sensitivity. Among them, in particular, the triarylsulfonium salt having a triaryl structure represented by the following formula (200) is further preferred from the viewpoint of sensitivity. In addition, this is because when the above photoacid generator is the above aromatic sulfonium salt, the above composition can form a cured product having excellent temporal stability of light absorption.

[0390] In addition, this is because the above-described composition can reduce heat-induced damage to peripheral components such as a substrate during curing, and the degree of freedom in selecting the peripheral components is increased.

[0607] (2) Then, the coating film was dried in an oven at 80 °C for 5 minutes to remove the solvent. Using a high-pressure mercury lamp, ultraviolet rays of 1500 mJ / cm 2 were irradiated for curing treatment to obtain a sample for evaluation. The obtained sample for evaluation was left standing in a constant temperature and humidity chamber at 60 °C and 90% for 5 days, and the changes in transmittance at 496.0 nm (λmax1, from the compound represented by formula (H-1)) before and after the damp heat test (Evaluation 1), and the changes in transmittance at 596.0 nm (λmax2, from the compound represented by formula (H-2)) (Evaluation 2) were investigated respectively, and evaluated according to the following criteria. The results are shown in Table 1 and Table 2 above.

[0608] It should be noted that the change in transmittance is a value expressed as "(transmittance before the test - transmittance after the damp heat test) (%)".

Using a visible ultraviolet spectrophotometer V-670 manufactured by JASCO Corporation, the transmittance spectrum at 496.0 nm of the compound (pyrromethene dye) represented by formula (H-1) was measured. The results are shown in Table 4 below.

[0631] (Method for preparing samples for evaluation before curing)

[0632] (1) The above composition was coated on a substrate (PET film A9300, 100 μm manufactured by Toyobo Co., Ltd.) by the bar coating method.

[0633] The thickness of the coating film was adjusted so that the transmittance at the maximum absorption wavelength of the sample for evaluation before curing became about 4 to 7%.

[0634] (2) Then, the coating film was dried at 80°C for 5 minutes using an oven to remove the solvent, and a sample for evaluation before curing was obtained.
