Description

[Technical Field]

[0001] The present invention relates to compositions, cured products or molded articles, optical components, and lenses. [Background technology]

[0002] Traditionally, glass materials have been used as optical components in imaging modules for cameras, video cameras, camera-equipped mobile phones, video phones, and camera-equipped door phones. While glass materials have been favored due to their various optical properties and excellent environmental resistance, they have drawbacks such as difficulty in reducing weight and miniaturization, as well as poor processability and productivity. In contrast, resin-cured materials can be mass-produced and have excellent processability, and have therefore come to be used in various optical components in recent years.

[0003] In recent years, with the miniaturization of imaging modules, there has been a demand for miniaturization of the optical components used in imaging modules. However, miniaturizing optical components leads to the problem of chromatic aberration. Therefore, in optical components using cured resins, it is being considered to correct chromatic aberration by adjusting the Abbe number using monomers or additives in the curable composition.

[0004] Polycyclic fused ring compounds, which contain nitrogen atoms among the atoms constituting the fused ring, exhibit low Abbe number νd or high partial dispersion ratio θg,F value as wavelength dispersion characteristics of their refractive index, and are being developed as materials for optical components used in imaging modules. For example, Patent Document 1 describes a thermoplastic resin having a structural unit containing a polycyclic fused ring in which nitrogen atoms are constituting the atoms constituting the fused ring, as an optical transparent resin. On the other hand, since the optical components of the imaging module are used in light-irradiated environments such as outdoors, it is also important to suppress discoloration of the cured material (i.e., a decrease in transmittance) that occurs when used or stored for a long period of time in light-irradiated environments such as outdoors (hereinafter also referred to as "light resistance"). In our previous research, as described in Patent Document 2, we have found that when using a compound containing a nitrogen-containing condensed aromatic ring in its structure as a monomer, using an unsaturated carbonyl compound with a specific structure, such as methyl cinnamate, improves light resistance because this unsaturated carbonyl compound acts as a quencher (light-quenching agent).

[0006] Further investigations by the present inventors revealed that, in the technology using monomers having nitrogen-containing condensed aromatic rings, the technology of incorporating unsaturated carbonyl compounds of a specific structure, such as methyl cinnamate, as a quencher, as described in Patent Document 2, does not provide sufficiently high light resistance, and there is room for further improvement.

Furthermore, the present invention aims to provide a cured product or molded article obtained from this composition, as well as optical components and lenses containing this cured product or molded article.

[0026] The composition of the present invention results in a cured or molded product with excellent light resistance. Therefore, optical components and lenses of the present invention that include this cured or molded product as a component can suppress discoloration even when used over long periods in light-irradiated environments such as outdoors. [Modes for carrying out the invention]

[0027] The present invention will now be described in detail. The following descriptions of constituent elements may be based on representative embodiments or specific examples, but the present invention is not limited to such embodiments.

[0028] <Composition> The composition of the present invention contains the following components A and B. Component A: A compound having a nitrogen-containing condensed aromatic ring as a substructure. Component B: A compound represented by one of the general formulas (B1) to (B5) described below. As described later, component A contained in the composition of the present invention may be a polymerizable compound or a polymer, as long as it has the nitrogen-containing condensed aromatic ring as a partial structure. When the composition of the present invention contains a polymerizable compound containing a nitrogen-containing condensed aromatic ring (also simply referred to as "a compound containing a nitrogen-containing condensed aromatic ring") as component A, the composition of the present invention becomes a curable composition. When the composition of the present invention contains a polymer having a nitrogen-containing condensed aromatic ring (preferably a structural unit containing a nitrogen-containing condensed aromatic ring) as component A, the composition of the present invention becomes a resin composition. Hereinafter, the former will be referred to as the curable composition of the present invention, and the latter as the resin composition of the present invention. Furthermore, among the compositions of the present invention, compositions containing both a compound containing a nitrogen-containing condensed aromatic ring and a polymer having a nitrogen-containing condensed aromatic ring are classified as curable compositions of the present invention. In other words, the resin compositions of the present invention do not contain polymerizable compounds containing nitrogen-containing condensed aromatic rings. The composition of the present invention may contain, in addition to components A and B described above, other components as appropriate. Specifically, these other components may include, for example, (meth)acrylate monomers (monomers other than component A or B), thermal radical polymerization initiators, photoradical polymerization initiators, polymers or monomers other than those described above, dispersants, plasticizers, heat stabilizers, mold release agents, and other additives. It is preferable that the resin composition of the present invention does not contain polymerizable polymers or monomers, thermal radical polymerization initiators, or photoradical polymerization initiators.

[0029] Component A contained in the composition of the present invention contains a nitrogen-containing condensed aromatic ring as a partial structure. When the composition of the present invention is a curable composition containing a compound containing a nitrogen-containing condensed aromatic ring as component A, its polymer (cured product), and when the composition of the present invention is a resin composition containing a polymer having a nitrogen-containing condensed aromatic ring as component A, its molded product, have a maximum absorption wavelength in the ultraviolet region of approximately 300 to 400 nm. Therefore, it is considered that the Abbe number (νD) as a dispersion characteristic of the refractive index is low, or the partial dispersion ratio (θg, F value) is high, and that it exhibits excellent optical properties. However, polymers having the above-mentioned nitrogen-containing condensed aromatic ring are prone to degradation by light (photoreaction) due to the nitrogen-containing condensed aromatic ring contained as a partial structure. As a result of our previous studies, as described in Patent Document 2 above, we have found that by combining a specific unsaturated carbonyl compound having a specific structure, such as methyl cinnamate, with a specific fused ring compound containing a nitrogen atom, the unsaturated carbonyl compound acts as a quencher (light-quenching agent), energy transfer occurs from the polymer having the nitrogen-containing condensed aromatic ring, which is excited by absorbing light, to the light-quenching agent, and the polymer having the nitrogen-containing condensed aromatic ring returns to its ground state, thereby improving light resistance. However, further studies by our inventors have revealed that the effect of the unsaturated carbonyl compound having the specific structure on improving light resistance is not sufficient, and that there is a problem in that light resistance cannot be improved any further even if the amount of unsaturated carbonyl compound added is increased. To address this problem of light resistance plateauing, we have found that by including component B having a specific chemical structure instead of methyl cinnamate, even with a small amount of component B added, a significantly improved light resistance effect is observed compared to when methyl cinnamate is used. The reason for this is not clear, but it is presumed to be as follows. In the prior art described in Patent Document 2 above, in addition to the energy transfer from the polymer having the nitrogen-containing condensed aromatic ring in the transition state described above, it is thought that an unsaturated carbonyl compound having a specific structure, such as methyl cinnamate, which has received energy, undergoes a [2+2] photocycloaddition reaction to produce the corresponding cyclobutane compound. Of the hydrogen atoms on the cyclobutane ring in this cyclobutane compound, the hydrogen atom at the benzyl position is easily abstracted, and it is thought that a hydrogen abstraction reaction occurs by the polymer having the nitrogen-containing condensed aromatic ring, which is excited by absorbing light, resulting in the discoloration of the polymer having the nitrogen-containing condensed aromatic ring. In the present invention, it is estimated that a remarkably superior lightfastness improvement effect can be achieved by including as component B a compound represented by one of the general formulas (B1) to (B5) described later, in which at least three of the four hydrogen atoms in CH2=CH2 are replaced by substituents, and at least two of these substituents are aryl groups or heteroaryl groups, as a compound having a chemical structure that makes the above [2+2] photocycloaddition reaction less likely to occur due to steric hindrance, etc., and the subsequent hydrogen abstraction reaction less likely to occur.

[0030] [Component A: A compound having a nitrogen-containing condensed aromatic ring as a substructure] The composition of the present invention contains a compound having a nitrogen-containing condensed aromatic ring as a substructure as component A. Because component A contains a nitrogen-containing condensed aromatic ring as a substructure, the cured product of the curable composition of the present invention or the molded article of the resin composition of the present invention has absorption in the near-ultraviolet region, which can support anomalous dispersion of refractive index, such as lowering the Abbe number (νD) or increasing the partial dispersion ratio (θg,F). This enhances the chromatic aberration correction function when used as a composite lens.

[0031] (Nitrogen-containing fused aromatic ring) The nitrogen-containing condensed aromatic ring possessed by the compound as component A means a nitrogen-containing condensed aromatic ring that satisfies all of the following conditions (i) to (iii). (i) Having a fused ring structure in which two or more six-membered rings are fused together. (ii) Having at least one nitrogen atom (N) as a ring constituent atom. (iii) All ring-constituting atoms have p orbitals, and all of these p orbitals contribute to aromaticity. In other words, a nitrogen-containing condensed aromatic ring that satisfies all of the above (i) to (iii) (hereinafter also simply referred to as "nitrogen-containing condensed aromatic ring") is an aromatic heterocycle formed by the condensation of two or more six-membered rings, and is an aromatic ring that contains at least one nitrogen atom as a ring constituent atom of this aromatic heterocycle.

[0032] The provision in (i) above preferably has a fused ring structure in which two to five six-membered rings are fused together, and more preferably has a fused ring structure in which two six-membered rings are fused together. From the viewpoint of further improving lightfastness, the provision in (ii) above is that it is preferable to contain two or more nitrogen atoms as ring constituent atoms, more preferably two or three, and even more preferably two. The nitrogen-containing condensed aromatic ring may contain heteroatoms other than nitrogen atoms (N), such as oxygen atoms (O) or sulfur atoms (S), but it is preferable that it does not contain such heteroatoms. The provision in (iii) above means that all rings (monocyclic rings) constituting the nitrogen-containing condensed aromatic ring exhibit aromaticity. For example, in the compound represented by the general formula (A11) described later, the nitrogen-containing condensed aromatic ring is a fused ring structure formed by the fusion of two six-membered rings located on the lower right side of the structural formula. That is, the R located on the lower left side of the structural formula 11 The benzene ring which may have a nitrogen-containing ring and the five-membered ring located to the right of this benzene ring are not included in the above nitrogen-containing condensed aromatic ring. This means that R 11 This is because one of the carbon atoms constituting the five-membered ring located to the right of the benzene ring, which may have a p orbital, has a p orbital that does not contribute to aromaticity, and therefore does not satisfy the requirements of (iii) above. Furthermore, the group represented by any of the general formulas (Ar-a) to (Ar-c) described below has at least a quinoxaline ring structure as the nitrogen-containing condensed aromatic ring, and the group represented by the general formulas (Ar-d) or (Ar-e) described below has at least a quinazoline ring structure as the nitrogen-containing condensed aromatic ring. 1 and T2 or Z 1 and Z 2 When they are bonded to each other to form a nitrogen-containing condensed aromatic ring that satisfies all of the above (i) to (iii) together with a quinoxaline ring or a quinazoline ring, T 1 and T 2 or Z 1 and Z 2 including the aromatic ring formed by their bonding to each other, constitutes the above nitrogen-containing condensed aromatic ring.

[0033] Examples of the above nitrogen-containing condensed aromatic ring include nitrogen-containing condensed aromatic rings having one nitrogen atom: isoquinoline ring, quinoline ring; nitrogen-containing condensed aromatic rings having two nitrogen atoms: phthalazine ring, quinoxaline ring, quinazoline ring, cinnoline ring, naphthyridine ring having a different arrangement of nitrogen atoms from these; nitrogen-containing condensed aromatic rings having three nitrogen atoms: pyrido[3,4-b]pyrazine ring, pyrido[2,3-b]pyrazine ring; or nitrogen-containing condensed aromatic rings having four nitrogen atoms: pteridine ring, etc. Among these, from the viewpoint of further improving light resistance, a quinoxaline ring or a quinazoline ring is preferable.

[0034] The above nitrogen-containing condensed aromatic ring may have a substituent or may be unsubstituted. Further, when the above nitrogen-containing condensed aromatic ring has a substituent, adjacent substituents may be bonded to each other to form a ring. The form in which the above nitrogen-containing condensed aromatic ring is incorporated as a partial structure in the compound is not particularly limited. For example, a bond formed by removing one hydrogen atom possessed by any carbon atom constituting the ring of the nitrogen-containing condensed aromatic ring (hereinafter, also simply referred to as "bond on the nitrogen-containing condensed aromatic ring"), or a bond formed by removing one hydrogen atom possessed by any atom (preferably a carbon atom) in the substituent possessed by the nitrogen-containing condensed aromatic ring (hereinafter, also simply referred to as "bond on the substituent possessed by the nitrogen-containing condensed aromatic ring") incorporates it into the compound as a monovalent group or a divalent group.

[0035] For example, when the nitrogen-containing condensed aromatic ring is a quinoxaline ring or a quinazoline ring, the positions of the bonds on the quinoxaline ring or quinazoline ring are not particularly limited, but it is preferable that there be two selected from positions 5 to 8, with a combination of positions 5 and 8, or a combination of positions 6 and 7 being more preferable. Furthermore, when the bond is on a substituent on a quinoxaline ring or quinazoline ring, the substituent having the bond and the position of the bond are not particularly limited. The substituent having this bond is preferably an aromatic hydrocarbon group or an aromatic heterocyclic group, more preferably an aromatic hydrocarbon group having 6 to 12 carbon atoms, even more preferably an optionally substituted phenyl group (an optionally substituted phenylene group in the bonded state), and particularly preferably a phenyl group (a phenylene group in the bonded state). When the phenyl group has a bond, its position is preferably at position 4 (with the bonded position to the quinoxaline ring or quinazoline ring being position 1) (i.e., a 1,4-phenylene group).

[0036] Component A may be a polymerizable compound containing the above-mentioned nitrogen-containing condensed aromatic ring, or a polymer having the above-mentioned nitrogen-containing condensed aromatic ring (preferably a structural unit containing the above-mentioned nitrogen-containing condensed aromatic ring). When the composition of the present invention contains a polymerizable compound containing a nitrogen-containing condensed aromatic ring as component A, the composition of the present invention becomes a curable composition, and the cured product obtained by curing the composition of the present invention, i.e., polymerizing component A, can be used as a cured product with a low Abbe number (νD) or a high partial dispersion ratio (θg,F). Conversely, when the composition of the present invention contains a polymer having a structural unit containing a nitrogen-containing condensed aromatic ring as component A, the composition of the present invention becomes a resin composition, and the molded product obtained by molding the composition of the present invention can be used as a molded product with a low Abbe number (νD) or a high partial dispersion ratio (θg,F).

The following will detail compounds represented by general formula (A0), followed by compounds represented by general formula (A1) or (A2).

[0219] When the cured product and molded article of the present invention are used as lenses, they are required to have no absorption in the visible light region, i.e., to be transparent. The cured products and molded articles of the present invention exhibit substantially no absorption in the long-wavelength region of the visible light spectrum, and their transmittance decreases as the wavelength decreases. Therefore, the transparency of the cured products and molded articles of the present invention can be evaluated by measuring the transmittance at a wavelength of 430 nm. The transmittance of the cured product and molded article of the present invention at a wavelength of 430 nm is a value measured using an ultraviolet-visible spectrophotometer (for example, UV-2600 (product name, manufactured by Shimadzu Corporation)). Specifically, the transmittance at a wavelength of 430 nm is measured for a cured product with a thickness of approximately 500 μm, prepared using a transparent glass mold with a diameter of 20 mm and a thickness of 500 μm, in the same manner as the preparation of the photocured sample described in Example 1 below. In addition, the transmittance at a wavelength of 430 nm is measured for a molded article with a thickness of approximately 500 μm, prepared using a spacer with a thickness of 500 mm, in the same manner as the preparation of the evaluation sample described in Example 2 below. Furthermore, light irradiation tests to evaluate the light resistance of the cured product and molded article are performed based on the xenon light irradiation test described in the examples below.

[0220] The following lists preferred values ​​for the transmittance of cured products and molded articles at a wavelength of 430 nm, as measured by the method described above. The transmittance of the cured product and molded article of the present invention immediately after production, i.e., the transmittance before the light irradiation test, is not particularly limited, but is preferably 80% or more, more preferably 82% or more, even more preferably 83% or more, and particularly preferably 85% or more.

The decrease in transmittance of the cured product and molded article of the present invention before and after the light irradiation test is not particularly limited, but in Evaluation 3 described below (decrease before and after the 48-hour xenon light irradiation test), it is preferably 15% or less, more preferably 12% or less, even more preferably 8% or less, and particularly preferably 5% or less. The decrease in transmittance before and after the above-mentioned light irradiation test is calculated by subtracting the transmittance value after the light irradiation test from the transmittance value before the light irradiation test.

[0221] Furthermore, preferred values ​​for the transmittance at a wavelength of 430 nm of a composite lens including a lens substrate manufactured using the cured product or molded article of the present invention, as described later, are stated below.

The decrease in transmittance of the composite lens of the present invention before and after the light irradiation test is not particularly limited, but in evaluation 6 described below (decrease before and after a 240-hour xenon light irradiation test), it is preferably 15% or less, more preferably 12% or less, even more preferably 8% or less, and particularly preferably 5% or less. The decrease in transmittance before and after the above-mentioned light irradiation test is calculated by subtracting the transmittance value after the light irradiation test from the transmittance value before the light irradiation test. The transmittance of the composite lens of the present invention at a wavelength of 430 nm was measured using an ultraviolet-visible spectrophotometer (for example, UV-2600 (product name, manufactured by Shimadzu Corporation)). Specifically, the transmittance at a wavelength of 430 nm was measured for a composite lens manufactured in the same manner as the composite lens described in Reference Example 1 below.

[0222] [Method for manufacturing hardened products] The cured product of the present invention can be manufactured by a method comprising at least one of a step of photocuring and a step of thermal curing of the curable composition of the present invention. In particular, the method for manufacturing the cured product preferably includes a step of forming a semi-cured product by irradiating the curable composition with light or heating the curable composition, and a step of forming a cured product by irradiating the obtained semi-cured product with light or heating the semi-cured product.

[0223] Unless otherwise specified, the descriptions of "step to form a semi-cured product," "step to form a cured product," and "semi-cured product" in sections

[0106] to

[0117] ,

[0118] to

[0124] and

[0125] of International Publication No. 2019 / 044863, respectively, can be applied as is, with "curable composition" replaced by "curable composition of the present invention." In this invention, the pressure during pressurized deformation in the "process of forming a cured product" is preferably 0.098 MPa to 9.8 MPa, more preferably 0.154 MPa to 4.9 MPa, and even more preferably 0.154 MPa to 2.94 MPa.

[0224] [Method for manufacturing molded products] The molded article of the present invention can be manufactured by molding the resin composition of the present invention. Examples of molding methods for the molded article include heat and pressure molding, and for example, compression molding, injection molding, extrusion molding, blow molding, embossing, etc. can be employed.

[0225] Before performing heat-pressure molding, the resin composition of the present invention may be pelletized. Pelletizing the resin composition of the present invention improves the handling of the resin during heat-pressure molding. When pelletizing the resin composition of the present invention, for example, a vented single-screw extruder can be used.

[0226] When performing compression molding, a spacer of the desired thickness is used, the resin composition of the present invention (preferably pellets of the resin composition of the present invention) is sandwiched between resin films such as polyimide films, heated and compressed, then the spacer and the resin film are removed and cooled to room temperature (including air cooling) to form the product. The conditions for performing heat compression are as follows: the heating temperature is preferably 180 to 450°C, more preferably 180 to 390°C; the pressure is preferably 0.098 MPa to 9.8 MPa, more preferably 0.294 MPa to 9.8 MPa, and even more preferably 1.0 MPa to 9.8 MPa; and the pressurizing time is preferably 30 to 1000 seconds, more preferably 30 to 500 seconds, and even more preferably 60 to 500 seconds.

[0227] When performing injection molding, an injection molding machine (including an injection compression molding machine) is used. In the injection molding machine, the molten resin composition of the present invention is stored at the tip of a cylinder, and then the molten resin composition of the present invention is injected into a mold to form the product. A commonly used injection molding machine can be used. Preferably, the cylinder is made of a material that has low adhesion to the resin composition of the present invention and exhibits corrosion resistance and abrasion resistance. An example of an injection molding machine is the Micro-1 manufactured by Meiho Co., Ltd.

[0228] The cylinder temperature during injection molding is preferably 200 to 450°C, and more preferably 250 to 390°C. The mold temperature is preferably 50 to 300°C, and more preferably 100 to 250°C.

[0229] [Applications of cured products and molded articles] The cured products and molded articles of the present invention are cured products exhibiting a low Abbe number (νD) or a high partial dispersion ratio, and also exhibit excellent light resistance, so they can be used in a variety of applications, and are particularly suitable for use in optical components.

[0230] <Optical components> The type of optical component is not particularly limited, but it can be suitably used as an optical component that transmits light (so-called passive optical component). Examples of optical functional devices equipped with such optical components include various display devices (liquid crystal displays or plasma displays, etc.), various projector devices (OHP (Overhead projector), liquid crystal projector, etc.), optical fiber communication devices (optical waveguides, optical amplifiers, etc.), and imaging devices such as cameras or video cameras.

[0231] Examples of passive optical components include lenses, prisms, prism sheets, panels (plate-shaped molded bodies), films, optical waveguides (film-like or fiber-like, etc.), optical discs, and encapsulants for LEDs (Light Emitting Diodes). Passive optical components may be provided with any coating layer or additional functional layer as needed. For example, passive optical components may be provided with a protective layer to prevent mechanical damage to the coated surface due to friction or abrasion, a light-absorbing layer to absorb undesirable wavelengths of light that cause deterioration of inorganic particles or substrates, a transmission-shielding layer to suppress or prevent the transmission of reactive low molecules such as moisture or oxygen gas, an anti-glare layer, an anti-reflective layer, a low refractive index layer, etc. Specific examples of coating layers include transparent conductive films or gas barrier films made of inorganic oxide or inorganic nitride coating layers, and gas barrier films or hard coat films made of organic coating layers. For forming the coating layer, known coating methods such as vacuum deposition, CVD (Chemical Vapor Deposition), sputtering, dip coating, and spin coating can be used.

[0232] [Lens substrate] The optical component may be a lens substrate. That is, the cured product or molded body of the present invention may be used as a lens substrate. In this specification, "lens substrate" means a single component capable of exhibiting lens function. Lens substrates manufactured using the cured product or molded body of the present invention exhibit a low Abbe number, a high partial dispersion ratio, and excellent light resistance. Preferably, the refractive index of the lens substrate can be arbitrarily adjusted by appropriately adjusting the type of monomer constituting the curable composition of the present invention or the monomer component constituting the polymer as component A contained in the resin composition of the present invention, and furthermore, a lens substrate with high refractive index, high partial dispersion ratio, and lightweight properties can be obtained.

[0233] A film or component may be provided on or around the surface of the lens substrate depending on the lens's usage environment or application. For example, a protective film, anti-reflective film, hard coat film, etc., can be formed on the surface of the lens substrate. Furthermore, a lens substrate manufactured using the cured product or molded body of the present invention can be laminated with one or more other lens substrates selected from glass lens substrates, plastic lens substrates, etc. (hereinafter referred to as "other lens substrates") to form a composite lens. Such composite lenses can be manufactured, for example, by photocuring the curable composition of the present invention on another lens substrate to form a semi-cured product, and then heating the obtained semi-cured product to form a cured product. The semi-curing step and the cured product formation step can preferably be applied as described above. Since the curable composition of the present invention has excellent photocuring sensitivity, composite lenses of excellent quality can be obtained. In the present invention, excellent photocuring sensitivity means that a gel-like or rubber-like semi-cured product can be obtained from a liquid curable composition by a photocuring reaction. Furthermore, when using the resin composition of the present invention, for example, a composite lens can be obtained by using an injection molding machine to inject the molten pelletized resin composition of the present invention into a mold, covering all surfaces of the resin not in contact with the mold with a transparent glass lens, spreading it out, and then separating the mold after cooling. The lens substrate may be fitted and fixed around a substrate holding frame or the like. However, these films or frames are components added to the lens substrate and are distinct from the lens substrate itself as referred to in this specification.

[0234] When using the lens substrate as a lens, the lens substrate itself may be used as a lens alone, or it may be used as a lens by adding the aforementioned film or frame, or other lens substrates. The type or shape of the lens using the lens substrate is not particularly limited, but the maximum thickness is preferably 0.1 to 10 mm. The maximum thickness is more preferably 0.1 to 5 mm, and even more preferably 0.15 to 3 mm. Furthermore, the lens substrate is preferably circular in shape with a maximum diameter of 1 to 1000 mm. The maximum diameter is more preferably 2 to 200 mm, and even more preferably 2.5 to 100 mm.

[0235] The lens substrate is preferably used for imaging lenses in mobile phones or digital cameras, or for photographic lenses in televisions and video cameras, as well as for automotive lenses and endoscope lenses.

[0236] <Bonded Lens> A bonded lens can be manufactured by bonding a lens substrate or lens made using the composition of the present invention to another lens using a lens adhesive.

[0237] [Other lenses] Other lens types are not particularly limited and include, for example, disc-shaped convex lenses, concave lenses, meniscus lenses, aspherical lenses, cylindrical lenses with cylindrical lens surfaces, ball lenses, rod lenses, etc. Furthermore, the materials of the other lenses are not particularly limited and may be glass lenses, resin lenses, or composite lenses.

[0238] (Glass lens) Any publicly known glass lens can be used without restriction. An example of a commercially available glass lens is the BK7 (product name) manufactured by Ohara Corporation. The same type of glass lens can be used when the composite lens includes a glass lens.

[0239] (Resin lenses, composite lenses) A resin lens refers to a lens made from a cured resin. In this specification, a composite lens means a lens comprising a layer made of glass and a resin layer. The resin layer is a layer made of a cured resin. Each layer included in the composite lens may be a lens (single lens), in which case it is preferable that the optical axes of each single lens (the line connecting the centers of curvature of the two spherical surfaces) coincide. The composite lens may have the resin layer on its surface or internally.

[0240] [Lens adhesive] For lens adhesives, commonly used adhesives can be used without restriction. As a lens adhesive, it is particularly preferable to use a lens adhesive containing a compound represented by general formula (1). A lens adhesive containing a compound represented by general formula (1) absorbs ultraviolet light while exhibiting excellent resistance to ultraviolet irradiation. Therefore, by using this lens adhesive, a cured product with high photostability can be obtained as a bonded lens. Furthermore, the adhesive layer formed from a lens adhesive containing a compound represented by general formula (1) has high resistance to thermal shock.

[0284] Examples of structural units represented by the above general formula (p1) include the following structural units. However, the structural units are not limited to these. In the chemical structural formula below, Me represents a methyl group, and t-Bu represents a tert-butyl group.

[0285] [ka]

[0286] The proportion of structural units containing aromatic rings (b1) among all structural units constituting polymer B is preferably 10 to 97% by mass, more preferably 20 to 96% by mass, and particularly preferably 30 to 95% by mass from the viewpoint of further improving transmittance. If polymer B has structural units other than structural units (b1) and (b2), the proportion of structural units (b1) containing aromatic rings to the total structural units constituting polymer B is preferably 10 to 80% by mass, more preferably 20 to 80% by mass, and even more preferably 30 to 75% by mass.

[0287] The proportion of structural units containing aromatic rings (b1) and structural units containing hydrogen bonding groups (b2) among all structural units constituting polymer B can be determined by first determining the component corresponding to the structural unit containing aromatic rings (b1) in the monomer components used to obtain the polymer, then determining the component corresponding to the structural unit having hydrogen bonding groups (b2) in the remaining monomer components, and then determining the mass ratio of these components. For example, in the case of a polyurethane synthesized by addition polymerization of a bifunctional isocyanate compound (A1) and a diol compound (B1) having aromatic rings, the proportion of the isocyanate compound (A1) in the monomer components corresponds to the proportion of the above structural unit (b1), and the proportion of the diol compound (B1) in the monomer components corresponds to the proportion of the above structural unit (b2). Furthermore, in the case of polymers obtained through elimination reactions during synthesis, for example, in the case of a polyamide obtained by condensation polymerization of a bifunctional acid chloride compound (A2) having an aromatic ring and a compound (B2) having two primary amino groups, the structural unit obtained by eliminating two chlorine atoms from the acid chloride compound (A2) corresponds to structural unit (b1), and the structural unit obtained by eliminating two hydrogen atoms from compound (B2) (i.e., one hydrogen atom from each of the two primary amino groups) corresponds to structural unit (b2). Therefore, the content ratio of structural units (b1) and (b2) can be determined from the mass ratio of these compounds (A2) and (B2).

[0288] (b2) Structural units having hydrogen bonding groups The polymer B described above has a structural unit (b2) that has hydrogen bonding groups. The hydrogen bonding group of the above structural unit (b2) refers to a group having a hydrogen atom capable of forming a hydrogen bond, and examples include hydroxyl groups, carboxyl groups, sulfo groups, phosphate groups, phosphonic acid groups, amino groups, sulfanyl groups, amide groups, urethane groups, urea groups, thiourethane groups, thiourea groups, or sulfonamide groups. Of the above, the hydroxyl group, carboxyl group, sulfo group (sulfonic acid group, -S(=O)2(OH)), phosphate group (-OP(=O)(OH)2), phosphonic acid group (-P(=O)(OH)2), and sulfanyl group are monovalent groups. Among the above, the amino group, amide group, and sulfonamide group mean a monovalent group or a divalent group having a hydrogen atom capable of hydrogen bonding. These monovalent groups respectively mean an amino group (-NH2), an amide group (-CONH2), and a sulfonamide group (-SO2NH2), and these divalent groups having a hydrogen atom capable of hydrogen bonding respectively mean an amino group (>NH), an amide group (-CONH-), and a sulfonamide group (-SO2NH-). Among the above, the urethane group (-NHC(=O)O-), urea group (-NR a C(=O)NH-), thiourethane group (-NHC(=O)S- or -NHC(=S)O-), and thiourea group (-NR a C(=S)NH-) are divalent groups having a hydrogen atom capable of hydrogen bonding. The above R a is a hydrogen atom, an alkyl group, a monovalent aliphatic or aromatic heterocyclic group, or a monovalent aromatic hydrocarbon ring group, and a hydrogen atom is preferred.

[0289] The hydrogen-bonding group contained in the above structural unit (b2) is preferably at least one of a hydroxy group, carboxy group, sulfo group, phosphoric acid group, phosphonic acid group, amino group, sulfanyl group, amide group, urethane group, urea group, thiourethane group, thiourea group, and sulfonamide group. From the viewpoint of further improving the adhesion, it is more preferably at least one of a hydroxy group, amide group, urethane group, and urea group. The number of hydrogen-bonding groups contained in one structural unit may be one, or may be two or more. When two or more are contained, these two or more hydrogen-bonding groups may be partially or entirely the same hydrogen-bonding group, or may be different hydrogen-bonding groups.

[0304] (b3) Other structural units Polymer B may contain structural units other than the structural units (b1) and (b2) described above (hereinafter also referred to as "other structural units"). Other structural units mentioned above are not particularly limited as long as they do not have either an aromatic ring or the aforementioned hydrogen bonding group, and include structural units derived from commonly used monomers such as (meth)acrylic acid ester compounds, vinyl ester compounds, (meth)acrylonitrile compounds, and maleic anhydride compounds. By including these structural units, the permeability and moisture heat resistance can be further improved. Among these, monomers selected from (meth)acrylic acid ester compounds and (meth)acrylonitrile compounds are preferred as monomers for deriving other structural units, with (meth)acrylic acid ester compounds being more preferred.

[0305] Specifically, examples include acrylic acid ester compounds such as alkyl acrylates (preferably those with 1 to 20 carbon atoms in the alkyl group) (specifically, for example, methyl acrylate, ethyl acrylate, propyl acrylate, butyl acrylate, amyl acrylate, ethylhexyl acrylate, octyl acrylate, t-octyl acrylate, chloroethyl acrylate, glycidyl acrylate, methoxybenzyl acrylate, tetrahydrofurfuryl acrylate, etc.), methacrylic acid ester compounds such as alkyl methacrylates (preferably those with 1 to 20 carbon atoms in the alkyl group) (for example, methyl methacrylate, ethyl methacrylate, propyl methacrylate, isopropyl methacrylate, amyl methacrylate, hexyl methacrylate, cyclohexyl methacrylate, chlorbenzyl methacrylate, octyl methacrylate, glycidyl methacrylate, tetrahydrofurfuryl methacrylate, etc.), acrylonitrile, methacrylonitrile, etc. Of the monomers mentioned above, alkyl (meth)acrylate compounds with 4 to 20 carbon atoms in the alkyl group are particularly preferred from the viewpoint of further improving transmittance.

However, an appropriate eluent can be selected and used as appropriate depending on the sample being measured. (Measurement conditions) Measuring instrument: HLC-8320GPC (product name, manufactured by Tosoh Corporation) The columns used were TOSOH TSKgel HZM-H (product name, manufactured by Tosoh Corporation), TOSOH TSKgel HZ4000 (product name, manufactured by Tosoh Corporation), and TOSOH TSKgel HZ2000 (product name, manufactured by Tosoh Corporation).

The lower limit is preferably 3% by mass or more, more preferably 5% by mass or more, and even more preferably 10% by mass or more.

[0313] ((meth)acrylate monomer) The lens adhesive may contain a (meth)acrylate monomer. The same (meth)acrylate monomers as those listed above for the curable composition of the present invention can be used. Preferred examples of (meth)acrylate monomers to be included in lens adhesives include monofunctional (meth)acrylate monomers having an aromatic ring, such as phenoxyethyl acrylate (monomer 1 above) or benzyl acrylate; (meth)acrylate monomers having an aliphatic group, such as monomer a (2-ethylhexyl acrylate), monomer b (1,6-hexanediol diacrylate), monomer c (1,6-hexanediol dimethacrylate); and (meth)acrylate monomers having a hydroxyl group, such as monomer d (2-hydroxyethyl acrylate), monomer e (hydroxypropyl acrylate), or monomer f (4-hydroxybutyl acrylate).

[0314] [ka]

[0315] There are no particular restrictions on how (meth)acrylate monomers can be obtained; they may be obtained commercially or manufactured by synthesis. When obtained commercially, for example, the following can be preferably used: Viscoat #192 PEA (phenoxyethyl acrylate) (manufactured by Osaka Organic Chemical Industry Co., Ltd.), Viscoat #160 BZA (benzyl acrylate) (manufactured by Osaka Organic Chemical Industry Co., Ltd.), 2EHA (monomer a) (manufactured by Toagosei Co., Ltd.), A-HD-N (monomer b) (manufactured by Shin Nakamura Chemical Industry Co., Ltd.), HD-N (monomer c) (manufactured by Shin Nakamura Chemical Industry Co., Ltd.), HEA (monomer d) (manufactured by Osaka Organic Chemical Industry Co., Ltd.), Light ester HOP-A(N) (monomer e) (manufactured by Kyoeisha Chemical Co., Ltd.), and 4-HBA (monomer f) (manufactured by Osaka Organic Chemical Industry Co., Ltd.).

[0316] When a lens adhesive contains (meth)acrylate monomer, the (meth)acrylate monomer content is preferably 5 to 90% by mass, more preferably 10 to 85% by mass, and even more preferably 20 to 80% by mass, based on the total mass of the lens adhesive. By adjusting the amount of (meth)acrylate monomer in the lens adhesive, the function of relieving stress when the cured product deforms due to heat can be adjusted.

[0317] (Polymerization initiator) The lens adhesive preferably contains a photoradical polymerization initiator. The description of the photoradical polymerization initiator described in the above-mentioned composition of the present invention can be applied as the photoradical polymerization initiator. Furthermore, the lens adhesive may contain a thermal radical polymerization initiator in addition to the photoradical polymerization initiator. By further including a thermal radical polymerization initiator, curing in areas not reached by light can be accelerated. As the thermal radical polymerization initiator, the description of the thermal radical polymerization initiator described in the composition of the present invention above can be applied.

[0318] [Manufacturing of bonded lenses] A bonded lens can be obtained by overlapping two lenses using a lens adhesive, and then curing the adhesive to form an adhesive layer. It is preferable to perform the curing after the overlapping process and after removing any air bubbles mixed into the adhesive. The adhesive can be cured by light irradiation or heating. It is preferable to cure by at least light irradiation. Alternatively, a heating step may be performed after light irradiation. The curing of the adhesive by light irradiation and heating is not particularly limited as long as an adhesive layer is formed, and it can be cured by conventional methods.

[0319] The thickness of the adhesive layer is preferably 10 to 50 μm, and more preferably 20 to 30 μm. A thickness of 10 μm or more allows for sufficient UV absorption. A thickness of 50 μm or less allows for high adhesion while increasing transmittance in the short wavelength region of visible light (400-430 nm).

[0320] The refractive index of the adhesive layer at a wavelength of 587 nm is preferably 1.51 or higher, more preferably 1.53 or higher, and even more preferably 1.55 or higher. This is because it reduces the difference in refractive index between the adhesive layer and the lens being bonded. Furthermore, the cutoff wavelength is preferably 380 nm or less, more preferably 385 nm or less, and even more preferably 390 nm or less for an adhesive layer with a thickness of 30 μm. Here, the cutoff wavelength is defined as the wavelength at which the transmittance of the adhesive layer is 0.5% or less. The transmittance of the adhesive layer can be measured using a spectrophotometer (for example, the UV-2550 (product name) manufactured by Shimadzu Corporation). The refractive index and cutoff wavelength of the adhesive layer can be adjusted within the above range by controlling the amount of the compound represented by general formula (1) in the lens adhesive.

[0339] <Example 1: Curable composition and its cured product> (1) Preparation of curable compositions (compositions No. 101-104, 106-116, c11-c13) A curable composition was prepared by mixing each component and stirring until homogenized, resulting in the composition shown in the table below.

[0340] (2) Preparation of photocured samples The prepared composition was poured into a circular, transparent glass mold with a diameter of 20 mm (made of borosilicate glass with a hydrophobic surface treatment of dichlorodimethylsilane) so that the cured product thickness was 500 μm. An Execure3000 (product name, manufactured by HOYA Corporation) was used as the light source, and a short-wavelength cut filter LU0422 (product name, manufactured by Asahi Spectroscopic Co., Ltd.) was placed between the light source and the transparent glass mold. Then, under an atmosphere purged with nitrogen to an oxygen concentration of 1% or less, 1000 mJ / cm³ was applied from above the transparent glass mold. 2 Photocured samples were prepared by irradiating them with ultraviolet light. Then, in an atmosphere purged with nitrogen to reduce the oxygen concentration to 1% or less, they were heated at 200°C for 30 minutes, and then cooled to room temperature to be used as evaluation samples. The curing reaction was completed through the above ultraviolet irradiation process, and all cured products were obtained as completely cured products.

[0341] <Example 2: Resin composition (Composition No. 105, c14~c16) and molded article thereof> Using a 500 μm thick spacer, polyimide film was placed above and below the resin pellet sample prepared above, preheated at 200-230°C for 3 minutes, pressurized at 7 MPa for 5 minutes, then removed along with the spacer, cooled to room temperature, and used as the evaluation sample.

[0342] Compositions No. 101 to 116 are the compositions of the present invention, and compositions No. c11 to c16 are comparative compositions.

[0343] [Evaluation 1: Transmittance before irradiation test] For the obtained evaluation samples, the UV-Vis transmittance of the central part (5 mm in diameter) was measured using a UV-Vis spectrophotometer UV-2600 (product name, manufactured by Shimadzu Corporation), and the transmittance at a wavelength of 430 nm (before irradiation test) was determined.

[0344] [Evaluation 2: Transmittance after 48-hour xenon light irradiation test] Evaluation samples prepared using compositions No. 101-116 and No. c11-c16 were subjected to xenon light irradiation tests under the following conditions. This irradiation test is equivalent to an accelerated lightfastness test under sunlight conditions. For the evaluation samples after the xenon light irradiation test described above, the transmittance at a wavelength of 430 nm (after the irradiation test) was determined using the method described in Evaluation 1: Transmittance before irradiation test. (Xenon light irradiation conditions) Equipment: Xenon accelerated weathering tester Q-SUN Xe-1 (product name, manufactured by Q-Lab Corporation) Light source: Xenon arc lamp Optical filter: Extended UV Q / B (product name, manufactured by Q-Lab Corporation) Illuminance: 0.43W / m 2 (340nm illumination meter) Black panel temperature: 63℃ Exam duration: 48 hours

[0346] <Optical property measurement> The refractive index (nD), Abbe number (νD), and partial dispersion ratio (θg,F) of the cured product of the curable composition obtained in Example 1 and the molded article of the resin composition obtained in Example 2 were measured using an Abbe refractometer (Atago Corporation, product name: DR-M4). Three measurements were taken for each sample at 25°C, and the average value was used as the measurement result. The "refractive index (nD)" is the refractive index at a wavelength of 587.56 nm. The "Abbe number (νD)" and "partial dispersion ratio (θg,F)" are values ​​calculated from refractive index measurements at different wavelengths using the following formulas. νD = (nD-1) / (nF-nC) θg,F=(ng-nF) / (nF-nC) Here, nD represents the refractive index at a wavelength of 589 nm, nF represents the refractive index at a wavelength of 486 nm, nC represents the refractive index at a wavelength of 656 nm, and ng represents the refractive index at a wavelength of 436 nm. The cured products obtained from curable compositions No. 101-104 and 106-116, and the molded articles obtained from resin composition No. 105, all had low Abbe numbers of 26-20 and high partial dispersion ratios of 0.72-0.86, satisfying the anomalous dispersion of refractive index required for chromatic aberration correction lenses.

[0349] The components listed in the table are as follows. Note that the proportions of each component are based on mass, and "-" indicates that the component is not present.

[0350] (Component A) [ka]

[0351] Compound (A-35) was synthesized according to Synthesis Example 9 [Synthesis of A-35] described in paragraph

[0256] of International Publication No. 2020 / 009053. Compound (VI-2) was synthesized according to the [Synthesis of Compound (VI-2)] described in paragraph

[0233] of International Publication No. 2020 / 009053. Compound (A-28) was synthesized according to the synthesis method of compound (27) described in paragraph

[0139] of International Publication No. 2017 / 115649.

[0353] (Component B) [ka]

[0354] Compound (B-50) was synthesized based on Example 3 of U.S. Patent No. 4,218,392. Compound (B-56) was synthesized based on Example 5 of U.S. Patent No. 4,218,392.

[0357] From the results in Table 1, the following can be seen. Comparative composition No. c11 is not a composition defined in the present invention because it does not contain component B defined in the present invention. The cured product obtained from comparative composition No. c11 shows a significant decrease in transmittance to 45% before and after the light irradiation test, indicating poor light resistance. Furthermore, comparative compositions No. c12 and c13 are not compositions defined in the present invention because they use methyl cinnamate instead of component B defined in the present invention. The cured products obtained from these comparative compositions No. c12 and c13 both showed poor light resistance, with a decrease in transmittance of 17% before and after the light irradiation test. In particular, comparative composition No. c13 uses twice the amount of methyl cinnamate compared to comparative composition No. c12, yet there was no difference in the decrease in transmittance before and after the light irradiation test, suggesting that no further effect of suppressing the decrease in transmittance can be obtained when using methyl cinnamate. In contrast, the cured products obtained from curable compositions No. 101-104 and 106-116 of the present invention all exhibited excellent transmittance before the light irradiation test, and also showed excellent transmittance after the light irradiation test, demonstrating the ability to suppress the decrease in transmittance. Furthermore, comparative composition No. c14 is not a composition defined in the present invention because it does not contain component B defined in the present invention. The molded article obtained from comparative composition No. c14 shows a significant decrease in transmittance to 49% before and after the light irradiation test, indicating poor light resistance. Also, comparative compositions No. c15 and c16 are not compositions defined in the present invention because they use methyl cinnamate instead of component B defined in the present invention. The molded articles obtained from these comparative compositions No. c15 and c16 both showed poor light resistance, with a decrease in transmittance of 23% before and after the light irradiation test. In particular, comparative composition No. c16 uses twice the amount of methyl cinnamate compared to comparative composition No. c15, yet there was no difference in the decrease in transmittance before and after the light irradiation test, suggesting that no further effect of suppressing the decrease in transmittance can be obtained when using methyl cinnamate. In contrast, it was found that the molded article obtained from resin composition No. 105 of the present invention exhibits excellent transmittance before the light irradiation test, and also shows excellent transmittance after the light irradiation test, thus suppressing the decrease in transmittance. Thus, since the cured products obtained from the curable composition of the present invention and the molded articles obtained from the resin composition of the present invention have excellent light resistance, optical components and lenses that include these cured products or molded articles as constituent members can suppress discoloration even when used in light-irradiated environments such as outdoors for a long period of time.

[0358] <Reference Example 1 (Fabrication of a composite lens using the composition of the present invention)> (1) Preparation of curable compositions (compositions No. 117-125) Curable compositions (Compositions No. 117-125) were prepared by mixing each component and stirring until homogenized, according to the composition shown in the table below.

[0359] (2) Fabrication of composite lenses The composite lens was fabricated in a nitrogen-purged atmosphere with an oxygen concentration of 1% or less. Specifically, 50 mg of the curable composition was injected into a biconcave glass lens A (glass material: BK7, outer diameter 10 mm, radius of curvature of the surface in contact with the curable composition 12 mm, radius of curvature of the other surface 10 mm), and a molding die with a chromium nitride-treated surface was placed over it to expand the curable composition to a diameter of 10 mm. At this time, the film thickness of the curable composition No. 101 layer in the center was approximately 600 μm. After this state, an Execure3000 (product name, manufactured by HOYA Corporation) was used as a light source from above the glass lens A, and a short-wavelength cut filter LU0422 (product name, manufactured by Asahi Spectroscopic Co., Ltd.) was placed between the light source and the glass lens A, and a pressure of 300 mJ / cm² was applied. 2 Ultraviolet light was applied. Next, while maintaining the state of being sandwiched between the molding die and glass lens A, the curable composition is subjected to 0.196 MPa (2 kgf / cm²). 2 The temperature was raised to 200°C while applying pressure. Subsequently, a composite lens consisting of a biconcave glass lens A and a cured product of the curable composition was fabricated by separating the cured product of the curable composition from the molding die at a speed of 0.05 mm / sec.

[0360] [Evaluation 4: Transmittance before irradiation test] For the obtained composite lenses, the UV-Vis transmittance of the central part (5 mm in diameter) was measured using a UV-Vis spectrophotometer UV-2600 (product name, manufactured by Shimadzu Corporation), and the transmittance at a wavelength of 430 nm (before irradiation test) was determined.

[0361] [Evaluation 5: Transmittance after 240 hours of xenon light irradiation test] A xenon light irradiation test was conducted on composite lenses fabricated using compositions No. 117 to 125 under the following conditions. This irradiation test is equivalent to an accelerated light resistance test under sunlight conditions. For the composite lens after the xenon light irradiation test described above, the transmittance at a wavelength of 430 nm (after the irradiation test) was determined using the method described in Evaluation 4: Transmittance before irradiation test above. (Xenon light irradiation conditions) Equipment: Xenon accelerated weathering tester Q-SUN Xe-1 (product name, manufactured by Q-Lab Corporation) Light source: Xenon arc lamp Optical filter: Extended UV Q / B (product name, manufactured by Q-Lab Corporation) Illuminance: 0.43W / m 2 (340nm illumination meter) Black panel temperature: 63℃ Exam duration: 240 hours

[0362] [Evaluation 6: Decrease in performance before and after a 240-hour xenon light irradiation test] The difference between the transmittance at a wavelength of 430 nm (before irradiation test) obtained in Evaluation 4 above and the transmittance at a wavelength of 430 nm (after irradiation test) obtained in Evaluation 5 above was defined as the decrease in transmittance before and after the irradiation test.

[0363] [Rating 7: Thermal shock resistance of composite lenses] Thirty composite lenses were prepared using compositions No. 117 to 125, following the same procedure as for the composite lenses described above. To check the heat shock resistance of the obtained composite lenses, they were heated at 100°C for 48 hours, then allowed to cool to room temperature, further cooled to -40°C for 48 hours, and then returned to room temperature. Each composite lens was visually inspected and examined for cracks or delamination using a microscope (product name: VHX-1000, manufactured by Keyence Corporation, magnification: 200x). Lenses that showed no change before and after the test were judged to be good. The percentage of good lenses out of 30 was defined as the good quality rate, and the heat shock resistance was evaluated based on the following criteria. - Evaluation Criteria - A: The yield rate for good products was over 90%. B: The percentage of good products was between 80% and 90%. C: The percentage of good products was between 70% and 80%. D: The yield rate was less than 70%.

[0364] [Table 2]

[0365] The components listed in the table are as described in Table 1 above. Note that the proportions of each component are based on mass, and "-" indicates that the component is not present.

[0366] From the results in Table 2, the following can be seen. The composite lenses fabricated using the curable compositions No. 117 to 125 of the present invention all exhibited excellent transmittance before the light irradiation test of the cured material, and also showed excellent transmittance even after 240 hours of irradiation with xenon light, demonstrating that the decrease in transmittance could be suppressed and that they possessed excellent light resistance. Furthermore, composite lenses made using the curable compositions No. 117 to 125 of the present invention showed suppressed changes in appearance such as cracks or delamination even after heat shock testing, demonstrating excellent heat shock resistance. Thus, composite lenses made using the composition of the present invention have excellent light resistance comparable to cured products made using the curable composition of the present invention or molded articles made using the resin composition of the present invention, and also exhibit excellent heat shock resistance.

To this solution, a solution of 1.0 g of polymerization initiator (manufactured by Fujifilm Wako Pure Chemical Industries, Ltd., trade name: V-601) dissolved in 20 mL of cyclohexanone was added dropwise over 30 minutes, and the mixture was reacted at 80°C for 6 hours.

After allowing the reaction mixture to cool, it was added dropwise to a mixture of 200 mL of water and 1800 mL of methanol, and the precipitated powder was filtered and dried to obtain 30 g of polymer P10. The mass-average molecular weight (Mw) of the obtained polymer P10 was 19,000.

[0374] (1) Preparation of adhesive composition 1 Adhesive composition 1 was prepared by mixing 3.0 g of adhesive monomer I-6, 3.0 g of polymer P10, 2.0 g of dodecyl acrylate, 2.0 g of 4-hydroxybutyl acrylate, and 40 mg of Irgacure 819 (trade name, manufactured by BASF Japan) as a photopolymerization initiator, and stirring until homogenized.

[0375] (2) Fabrication of composite lenses The composite lens was fabricated in a nitrogen-purged atmosphere with an oxygen concentration of 1% or less. Specifically, 50 mg of curable composition No. 101 was injected into a biconcave glass lens A (glass material: BK7, outer diameter 10 mm, radius of curvature of the surface in contact with curable composition No. 101 is 12 mm, and the radius of curvature of the other surface is 10 mm). A molding die with a chromium nitride-treated surface was placed over it and the lens was expanded so that the diameter of curable composition No. 101 was 10 mm. At this time, the film thickness of the curable composition No. 101 layer in the center was approximately 600 μm. After this state, an Execure3000 (product name, manufactured by HOYA Corporation) was used as a light source from above glass lens A, and a short-wavelength cut filter LU0422 (product name, manufactured by Asahi Spectroscopic Co., Ltd.) was placed between the light source and glass lens A, and a 300 mJ / cm² light was applied. 2 Ultraviolet light was applied. Next, while maintaining the state of being sandwiched between the molding die and glass lens A, the curable composition No. 101 is subjected to 0.196 MPa (2 kgf / cm²). 2 The temperature was raised to 200°C while applying pressure. Subsequently, a composite lens 1 consisting of a biconcave glass lens A and a cured product of curable composition No. 101 was fabricated by separating the cured product of curable composition No. 101 from the molding die at a speed of 0.05 mm / sec.

[0376] (3) Fabrication of cemented lenses In a nitrogen-purged workbox, the composite lens 1 prepared above was placed horizontally, and the adhesive composition 1 prepared above was applied to the surface of the cured product of curable composition No. 101. Next, a biconvex glass lens B (glass material: BK7, outer diameter 10 mm, radius of curvature of the surface that will be joined with the biconcave glass lens A is 12 mm, and the radius of curvature of the other surface is 10 mm) was placed on top of the applied adhesive composition 1 and spread out to prevent air bubbles from forming. At this time, the amount of adhesive composition 1 applied was adjusted so that the film thickness of the adhesive composition 1 layer in the center was 20 μm. Next, in an atmosphere with an oxygen concentration of 1% or less, 300 mJ / cm² was applied from the side of the biconvex glass lens B using Execure3000 (product name, manufactured by HOYA Corporation). 2The adhesive composition 1 was cured by irradiation with ultraviolet light, and a bonded lens 1 was fabricated with a structure in which the following components were laminated in the order of biconcave glass lens A / cured product of curable composition No. 101 / cured product of adhesive composition 1 / biconvex glass lens B. For the resulting cemented lens 1, the transmittance was measured before and after a 48-hour xenon light irradiation test in the same manner as in evaluations 1 to 3 described above, and the decrease in transmittance before and after the irradiation test was calculated. When irradiating with xenon light, the cemented lens 1 was positioned so that the light entered from the side of the biconvex glass lens B. The transmittance before irradiation with xenon light at 430 nm was 77%, while the transmittance after irradiation with xenon light at 430 nm was 72%, indicating excellent light resistance with a transmittance decrease of 5%. This demonstrates that the bonded lens made using curable composition No. 101 of the present invention has excellent light resistance comparable to that of the circular cured product made using curable composition No. 101 of the present invention. Furthermore, bonded lenses made using curable compositions No. 102-104, 106-116, or resin composition No. 105 of the present invention also showed excellent light resistance comparable to that of the circular cured product made using the corresponding curable composition in Example 1. Thus, bonded lenses made using the composition of the present invention have excellent light resistance comparable to cured products made using the curable composition of the present invention or molded articles made using the resin composition of the present invention.
