[0005] Patent document 1: Japanese Patent Application Publication No. 9-327622. Summary of the Invention

[0006] The problem the invention aims to solve

[0007] Patent Document 1 discloses the use of the aforementioned surface coating agent to impart antibacterial properties to synthetic resin molded articles used in building materials, various interior structural materials, signs, displays, lighting fixtures, etc.

[0008] In recent years, the demand for antibacterial properties has been steadily increasing. In this context, endowing eyeglass lenses with the ability to inhibit bacterial growth (i.e., antibacterial properties) can enhance their added value. Furthermore, eyeglass lenses are exposed to light and moisture during long-term use by the wearer while assembled into eyeglasses. Therefore, eyeglass lenses require excellent light and water resistance in addition to their antibacterial properties.

[0009] One aspect of the present invention is to provide an eyeglass lens with excellent antibacterial properties, light resistance, and water resistance.

[0010] Solution for solving the problem

[0011] One aspect of the present invention relates to an eyeglass lens having a lens substrate and an inorganic layer, wherein the eyeglass lens further has a metal-containing layer between the lens substrate and the inorganic layer, the metal-containing layer comprising one or more metals selected from silver and platinum.

[0012] Silver and platinum are components that exhibit antibacterial properties. These components are contained in a layer beneath the inorganic layer of the aforementioned eyeglass lens. Therefore, the eyeglass lens exhibits excellent antibacterial properties and resistance to light and water.

[0013] Invention Effects

[0014] According to one aspect of the present invention, it is possible to provide an eyeglass lens with excellent antibacterial properties, light resistance, and water resistance. Attached Figure Description

[0016] [Eyeglass lenses]

[0017] The above-mentioned eyeglass lenses will be described in further detail below.

[0018] <Contains a metal layer>

[0019] The metal-containing layer of the aforementioned spectacle lens contains one or more metals selected from silver and platinum. In one embodiment, it may contain only silver or platinum, while in another embodiment, it may contain both silver and platinum. Examples of the metal's presence in the metal-containing layer include elemental or alloyed metals, inorganic or organic compounds, and metal ions. Inorganic compounds may be, for example, inorganic oxides. Furthermore, examples of the metal's presence in the metal-containing layer include metal complexes. The metal can exist in the metal-containing layer in various forms. For example, silver can be considered to ionize through at least partial oxidation and thus exhibit antibacterial properties.

[0020] The aforementioned metal-containing layer comprises one or both of a silver-containing component and a platinum-containing component. The description of the silver-containing and platinum-containing components is the same as that regarding the form in which the metal exists in the aforementioned metal-containing layer. In one embodiment, the metal-containing layer located between the lens substrate and the inorganic layer in the aforementioned spectacle lens may contain only one of a silver-containing component and a platinum-containing component, thereby exhibiting antibacterial properties and excellent light and water resistance. Furthermore, in another embodiment, the aforementioned metal-containing layer may contain both a silver-containing component and a platinum-containing component. This can suppress discoloration of the spectacle lens due to long-term use. Regarding this, the inventors speculate that when the metal-containing layer contains silver, it can be considered that the oxidation of silver occurs over time, causing the metal-containing layer to yellow; since platinum plays a role in controlling the oxidation of silver, yellowing can be suppressed. When the aforementioned metal-containing layer contains a silver-containing component, the silver-containing component may be only one type or two or more types. This is also the case when the aforementioned metal-containing layer contains a platinum-containing component.

[0021] The aforementioned metal-containing layer is a layer located between the lens substrate and the inorganic layer. It can be a layer directly deposited on the lens substrate by a film-forming method selected from wet and dry film-forming methods, or a layer indirectly deposited on the lens substrate through one or more other layers deposited on the lens substrate. When the total amount of the film-forming material (excluding solvents used during film formation) is taken as 100% by mass, the content of the metal-containing component selected from the silver-containing and platinum-containing components (the total content of the silver-containing and platinum-containing components if both are included) can be, for example, 0.010% by mass or more, 0.030% by mass or more, or 0.050% by mass or more; furthermore, it can be, for example, 1.500% by mass or less, 1.300% by mass or less, or 1.000% by mass or less. In one embodiment, the silver-containing component can be used alone as the film-forming material. In another embodiment, a mixture of the silver-containing component and one or more other components can be used as the film-forming material. The same applies to the platinum-containing component. When using both silver-containing and platinum-containing components, the platinum-containing component can be used in an amount, for example, 0.01 to 10 times the mass of the silver-containing component. The silver-containing and platinum-containing components can be used as film-forming materials, for example, in particulate form. The particle size can be, for example, 1 nm or more and 20 nm or less. In this invention and specification, "particle size" refers to the average particle size, which can be, for example, the arithmetic mean of the particle sizes of about 5 to 10 particles. When using the metal-containing component as a film-forming material in the form of inorganic oxide particles, these particles can be particles composed of only one inorganic oxide, or particles containing two or more inorganic oxides. In particles containing two or more inorganic oxides, at least one inorganic oxide can be silver oxide and / or platinum oxide.

[0022] The inorganic layer described in detail later can be a multilayer film with two or more inorganic layers. This multilayer film can be an antireflective film that prevents the reflection of light of a specific wavelength or wavelength range, or a reflective film that reflects light of a specific wavelength or wavelength range. In eyeglass lenses, as specific examples of layers disposed between such a multilayer film and the lens substrate, the following layers can be cited. One or more of these layers can be the aforementioned metal-containing layer.

[0023] (Curing layer)

[0052] By using a curable composition containing a metal component selected from silver and platinum components as the curable composition, the metal layer can be disposed between the lens substrate and the inorganic layer in the form of a cured layer formed by curing the curable composition.

[0053] As a method for applying the curable composition, known application methods such as spin coating, dip coating, and spray coating can be used. This is also the case for the application of the compositions used to form the various layers described later. The curing treatment can be light irradiation and / or heat treatment. The curing treatment conditions can be determined according to the types of various components contained in the curable composition and the composition of the curable composition. The film thickness of the cured layer formed by curing the curable composition is, for example, 1 μm or more and 100 μm or less. From the viewpoint of improving the scratch resistance of the surface, the film thickness of the cured layer is preferably 3 μm or more, more preferably 5 μm or more.

[0054] (Basal layer)

[0055] The aforementioned spectacle lens may have one or more base layers between the lens substrate and the inorganic layer. Furthermore, in one embodiment, one or more base layers may be present between the lens substrate and the cured layer formed by curing the curable composition, wherein the cured layer and the one or more base layers may be the aforementioned metal-containing layer. The number of base layers located between the lens substrate and the inorganic layer, or between the lens substrate and the cured layer formed by curing the curable composition, may be, for example, one or two layers. Examples of base layers include a layer that functions as an interference fringe suppression layer (e.g., an interference fringe suppression layer referred to as a λ / 4 layer) and a primer layer for improving adhesion. The aforementioned spectacle lens may have one or both of an interference fringe suppression layer and a primer layer between the lens substrate and the inorganic layer, or between the lens substrate and the cured layer of the curable composition.

[0056] Interference fringe suppression layer

[0057] An interference fringe suppression layer is a layer that suppresses the generation of interference fringes compared to the case without this layer. In light with wavelengths λ of 450–650 nm, a layer with an optical thickness of 0.2λ–0.3λ can function as an interference fringe suppression layer. The thickness of the interference fringe suppression layer, measured in physical film thickness, can be, for example, in the range of 50 nm–100 nm.

[0058] An interference fringe suppression layer can be formed, for example, by applying a dispersion containing at least metal oxide particles and resin to the surface of a lens substrate.

[0059] Metal oxide particles can function as a modulator of the refractive index of the interference fringe suppression layer. Examples of metal oxide particles include tungsten oxide (e.g., WO3), zinc oxide (e.g., ZnO), aluminum oxide (e.g., Al2O3), titanium oxide (e.g., TiO2), zirconium oxide (e.g., ZrO2), tin oxide (e.g., SnO2), beryllium oxide (e.g., BeO), and antimony oxide (e.g., Sb2O5). Two or more metal oxide particles can be used individually or in combination. Furthermore, composite oxide particles containing two or more metal oxides can also be used. From an optical perspective, the particle size of the metal oxide particles is preferably in the range of 5–30 nm.

[0060] The resin used as the interference fringe suppression layer can be at least one selected from polyurethane resin, acrylic resin, epoxy resin, etc., preferably polyurethane resin, and more preferably an aqueous resin composition containing polyurethane resin, i.e., an aqueous polyurethane resin composition. The aqueous polyurethane resin composition can be prepared, for example, by subjecting a polyol compound and an organic polyisocyanate compound, along with a chain extender as needed, to an urethane reaction in a solvent that is inactive to the reaction and has a high affinity for water to produce a prepolymer, and then neutralizing the prepolymer and dispersing it in an aqueous solvent containing a chain extender to increase its molecular weight. For such aqueous polyurethane resin compositions and their preparation methods, reference can be made to, for example, paragraphs 0009-0013 of Japanese Patent No. 3588375, paragraphs 0012-0021 of Japanese Patent Application Publication No. 8-34897, paragraphs 0010-0033 of Japanese Patent Application Publication No. 11-92653, and paragraphs 0010-0033 of Japanese Patent Application Publication No. 11-92655. Furthermore, as a water-based polyurethane resin composition, commercially available water-based polyurethane can be used directly, or it can be diluted with a water-based solvent as needed before use. Examples of commercially available water-based polyurethane resin compositions include the Evafanol series manufactured by Nichika Chemical Co., Ltd., the Superflex series manufactured by Daiichi Kogyo Pharmaceutical Co., Ltd., the Adeka Bon-Tighter series manufactured by Adico Co., Ltd., the Olest series manufactured by Mitsui Chemicals Co., Ltd., the Vondic series and Hydran series manufactured by D.E. Co., Ltd., the Impranil series manufactured by Bayer AG, the Soflanate series manufactured by Soflan Co., Ltd., the POIZ series manufactured by Kao Corporation, the Sanplene series manufactured by Sanyo Chemical Industries, Ltd., the Aizelax series manufactured by Hodogaya Chemical Industry Co., Ltd., and the NeoRez series manufactured by Zeneca Co., Ltd.

[0061] The dispersion used to form the interference fringe suppression layer may contain an aqueous solvent. An aqueous solvent refers to a solvent containing water, such as water, a mixture of water and a polar solvent, etc., preferably water. From the viewpoint of liquid stability and film-forming properties, the concentration of the solid component in the aqueous resin composition is preferably 1 to 60% by mass, more preferably 5 to 40% by mass. In addition to the resin component, the aqueous resin composition may also contain additives such as antioxidants, dispersants, and plasticizers, as needed. Furthermore, commercially available aqueous resin compositions may be diluted with solvents such as water, ethanol, or propylene glycol monomethyl ether (PGM) before use.

[0062] By using an aqueous resin composition containing a metallic component selected from silver and platinum, the metallic layer can be disposed between the lens substrate and the inorganic layer, between the lens substrate and a cured layer formed by curing the curing composition, or between the lens substrate and the primer layer in the form of a base layer (interference fringe suppression layer) formed by the aqueous resin composition. The aqueous resin composition is applied to a surface to be coated (e.g., the surface of the lens substrate) to form a coating layer. The coating layer is then cured by drying, such as through a drying process, to remove at least a portion of the aqueous solvent, thereby forming the base layer (interference fringe suppression layer).

[0063] primer layer

[0064] The primer layer can be, for example, an aqueous resin layer formed from an aqueous resin composition containing a resin and an aqueous solvent. The aqueous solvent contained in the aqueous resin composition is, for example, water, a mixture of water and a polar solvent, preferably water. From the viewpoint of liquid stability and film-forming properties, the concentration of the solids component in the aqueous resin composition is preferably 1 to 60% by mass, more preferably 5 to 40% by mass. In addition to the resin component, the aqueous resin composition may, as needed, contain additives such as antioxidants, dispersants, and plasticizers. Furthermore, commercially available aqueous resin compositions can be diluted with solvents such as water, ethanol, or propylene glycol monomethyl ether (PGM) for use.

[0065] The aqueous resin composition can contain resin components either dissolved in an aqueous solvent or dispersed as particles (preferably colloidal particles). Particularly preferred are dispersions of the resin components in an aqueous solvent (preferably water) in the form of particulate matter. In this case, from the viewpoint of dispersion stability, the particle size of the resin components is preferably 0.3 μm or less. Furthermore, from a stability perspective, the pH of the aqueous resin composition is preferably around 5.5 to 9.0 at 25°C. From a coating suitability perspective, the viscosity at a liquid temperature of 25°C is preferably 5 to 500 mPa·s, more preferably 10 to 50 mPa·s. Regarding the resin, refer to the above description of the resin for interference fringe suppression layers.

[0066] By using an aqueous resin composition containing a metal-containing component selected from silver and platinum components, the metal-containing layer can be disposed between a lens substrate and an inorganic layer, between a lens substrate and a cured layer formed by curing the curable composition, between an interference fringe suppression layer and an inorganic layer, or between an interference fringe suppression layer and a cured layer formed by curing the curable composition, in the form of a base layer (primer layer) formed from the aqueous resin composition. A coating layer is formed by applying the aqueous resin composition to a surface to be coated (e.g., the surface of the interference fringe suppression layer or the surface of the lens substrate), and the coating layer is cured by drying (e.g., drying treatment) to remove at least a portion of the aqueous solvent, thereby forming a base layer (primer layer). The film thickness of the primer layer can be, for example, in the range of 0.01 to 2.0 μm.

[0067] Lens substrate

[0068] The lens substrate for eyeglass lenses can be either a plastic lens substrate or a glass lens substrate. Glass lens substrates can be, for example, made of inorganic glass. From the viewpoint of being lightweight, not easily broken, and easy to handle, a plastic lens substrate is preferred. Examples of plastic lens substrates include styrene resins (represented by (meth)acrylic resin), polycarbonate resins, allyl resins, allyl carbonate resins such as diethylene glycol dielyl carbonate resin (CR-39), vinyl resins, polyester resins, polyether resins, polyurethane resins obtained by reacting isocyanate compounds with hydroxyl compounds such as diethylene glycol, thiopolyurethane resins obtained by reacting isocyanate compounds with polythiol compounds, and cured products (commonly referred to as transparent resins) formed by curing a curable composition containing a (thio)epoxide compound having one or more disulfide bonds within its molecule. Undyed lens substrates (colorless lenses) or dyed lens substrates (dyed lenses) can be used as lens substrates. The refractive index of the lens substrate can be, for example, around 1.60 to 1.75. However, the refractive index of the lens substrate is not limited to the above range; it can be within the above range or deviate from it. In this invention and this specification, refractive index refers to the refractive index relative to light with a wavelength of 500 nm. Furthermore, the lens substrate can be a lens with refractive power (so-called a power lens) or a lens without refractive power (so-called a non-power lens).

[0069] Eyeglass lenses can be various types, including single-focal lenses, multifocal lenses, and progressive lenses. The type of lens is determined by the surface shape of the two sides of the lens substrate. Furthermore, the surface of the lens substrate can be convex, concave, or flat. In typical lens substrates and eyeglass lenses, the object-side surface is convex, and the eye-side surface is concave. However, the present invention is not limited to this.

[0070] <Inorganic layer>

[0071] The aforementioned spectacle lens has an inorganic layer on the lens substrate. In this invention and specification, "inorganic layer" refers to a layer containing inorganic matter, preferably a layer containing inorganic matter as a main component. Here, "main component" refers to the component that constitutes the largest proportion of the layer, typically about 50% to 100% by mass relative to the mass of the layer, and more specifically about 90% to 100% by mass. The same applies to the main components described later. The inorganic layer can be a layer laminated on the surface of the lens substrate at least with a metal-containing layer in between.

[0072] In one embodiment, the aforementioned inorganic layer can be a multilayer film consisting of two or more inorganic layers. Examples of such multilayer films include those comprising one or more high-refractive-index layers and one or more low-refractive-index layers. This multilayer film can be an antireflective film with the property of preventing the reflection of light of a specific wavelength or wavelength range, or a reflective film with the property of reflecting light of a specific wavelength or wavelength range. In this invention and specification, the terms "high" and "low" in "high refractive index" and "low refractive index" are relative expressions. That is, a high-refractive-index layer refers to a layer with a higher refractive index than the low-refractive-index layer contained in the same multilayer film. In other words, a low-refractive-index layer refers to a layer with a lower refractive index than the high-refractive-index layer contained in the same multilayer film. The refractive index of the high-refractive-index material constituting the high-refractive-index layer can be, for example, 1.60 or higher (e.g., in the range of 1.60 to 2.40), and the refractive index of the low-refractive-index material constituting the low-refractive-index layer can be, for example, 1.59 or lower (e.g., in the range of 1.37 to 1.59). However, as mentioned above, the terms "high" and "low" in "high refractive index" and "low refractive index" are relative, so the refractive indices of high refractive index materials and low refractive index materials are not limited to the ranges mentioned above.

[0073] Specifically, as a high-refractive-index material for forming a high-refractive-index layer, examples include mixtures of one or more oxides selected from zirconium oxide (e.g., ZrO2), tantalum oxide (e.g., Ta2O5), titanium oxide (e.g., TiO2), aluminum oxide (e.g., Al2O3), yttrium oxide (e.g., Y2O3), hafnium oxide (e.g., HfO2), and niobium oxide (e.g., Nb2O5). On the other hand, as a low-refractive-index material for forming a low-refractive-index layer, examples include mixtures of one or more oxides or fluorides selected from silicon oxide (e.g., SiO2), magnesium fluoride (e.g., MgF2), and barium fluoride (e.g., BaF2). In the examples above, for convenience, oxides and fluorides are represented by stoichiometric composition; however, oxides and fluorides in a state of oxygen deficiency or fluorine excess relative to the stoichiometric composition can also be used as high-refractive-index or low-refractive-index materials.

[0074] Preferably, the high-refractive-index layer is a film primarily composed of a high-refractive-index material, and the low-refractive-index layer is a film primarily composed of a low-refractive-index material. Such a film (e.g., a vapor-deposited film) can be formed by using a film-forming material (e.g., a vapor-deposited material) primarily composed of the aforementioned high-refractive-index or low-refractive-index material. Sometimes, impurities are unavoidably mixed into the film and the film-forming material. Furthermore, other components may be included, such as other inorganic substances or known additives that assist in film formation, provided that the function of the main component is not impaired. Film formation can be performed using known film-forming methods; from the viewpoint of ease of film formation, vapor deposition is preferred, and vacuum vapor deposition is more preferred. The antireflective film can be, for example, a multilayer film consisting of 3 to 10 alternating high-refractive-index and low-refractive-index layers. The thicknesses of the high-refractive-index layer and the low-refractive-index layer can be determined based on the layer structure. In detail, the combination of layers and the thickness of each layer in a multilayer film can be determined by optical design simulation using known methods, based on the refractive index of the film-forming materials used to form the high-refractive-index and low-refractive-index layers, and the desired reflection and transmission characteristics that the multilayer film is intended to impart to the eyeglass lens. Furthermore, the multilayer film may include one or more layers primarily composed of conductive oxides (conductive oxide layers) at any location, preferably one or more vapor-deposited films of conductive oxides formed by vapor deposition using a vapor deposition material primarily composed of conductive oxides. The thickness of each of the high-refractive-index and low-refractive-index layers in the multilayer film can be, for example, 3–500 nm, and the total thickness of the multilayer film can be, for example, 100–900 nm. Unless otherwise specified, the film thicknesses in this invention and specification are physical film thicknesses.

[0075] The aforementioned spectacle lenses can contain more than one layer, which is typically included in spectacle lenses, at any location.

[0076] In the aforementioned eyeglass lenses, the metal-containing layer functions as an antibacterial layer, thereby exhibiting antibacterial properties. Furthermore, the inorganic layer functions, for example, as an antireflective film, thereby imparting antireflective properties to the eyeglass lenses against light of specific wavelengths or wavelength ranges.

[0077] [Glasses]

[0078] One aspect of the present invention relates to eyeglasses having the aforementioned spectacle lenses. Details regarding the spectacle lenses included in such eyeglasses are as described above. Known techniques can be applied to the structure of the frames and the like for the aforementioned eyeglasses.

[0080] The present invention will be further described below through embodiments. However, the present invention is not limited to the embodiments shown in the embodiments.

[0081] [Contains metallic components]

[0082] The "silver particles" listed in the "metallic composition" column of Table 1 are silver particles with a particle size of 2-5 nm (so-called silver nanoparticles).

[0083] The "platinum particles" listed in the "Metallic Components" column of Table 1 are platinum particles with a particle size of 2-5 nm (so-called platinum nanoparticles).

[0084] The "Silver Oxide Particles" listed in the "Metallic Components" column of Table 1 are ATOMY BALL-(UA) (an aqueous dispersion of particles containing silver oxide, silicon oxide, and aluminum oxide, with a particle size of 15 nm) manufactured by Nippon Kaisha Chemical Co., Ltd. The content listed in Table 1 is the content of silver oxide.

[0085] [Refer to the fabrication of lens 1]

[0086] <Plastic Lens Substrate>

[0087] The plastic lens substrate is made of eyeglass plastic lenses manufactured by Hoya Corporation (trade name EYNOA, refractive index 1.67).

[0088] <Interference fringe suppression layer (λ / 4 layer)>

[0089] 126g of 4-hydroxy-4-methyl-2-pentanone (DAA) and 350.5g of water were added to 305.0g of methanol. Further additions were 217.5g of thermoplastic resin (Superflex 170 manufactured by Daiichi Kogyo Pharmaceutical Co., Ltd.), 90.0g of a 40% by mass sol-like material (ZrO2 sol) containing HZ-407MH manufactured by Nissan Chemical Industries, Ltd. dispersed in methanol, and 1.0g of leveling agent (Y-7006 manufactured by Toray Dow Corning Co., Ltd.). The mixture was stirred at 20°C for 1 hour and filtered to obtain a λ / 4 layer solution.

[0090] The obtained λ / 4 layer was applied to the surface of the cleaned plastic lens substrate using a spin coating method. The substrate was then dried and cured in a drying device with an internal ambient temperature of 100°C for 20 minutes, forming λ / 4 layers on both sides of the lens substrate.

[0091] <Primer layer>

[0092] 126g of 4-hydroxy-4-methyl-2-pentanone (DAA) and 350.5g of water were added to 305.0g of methanol, followed by 217.5g of thermoplastic resin (Superflex 170 manufactured by Daiichi Kogyo Pharmaceutical Co., Ltd.) and 1.0g of leveling agent (Y-7006 manufactured by Toray Dow Corning Co., Ltd.). The mixture was stirred at 20°C for 24 hours to obtain a primer.

[0093] The obtained primer liquid was applied to the surface of the λ / 4 layer by immersion method and dried and cured in a drying device with an internal ambient temperature of 100°C for 20 minutes to form primer layers on both sides of the lens substrate.

[0094] Hard coating

[0095] A hard coating liquid was prepared by mixing 52 parts by weight of silica particles, 24 parts by weight of silane coupling agent (KBM-403 manufactured by Shin-Etsu Chemical Industry Co., Ltd., γ-glycidoxypropyltrimethoxysilane), and 24 parts by weight of polyfunctional epoxy compound (Denacol EX-321 manufactured by Nagase Chemical Co., Ltd., trimethylolpropane polyglycidyl ether).

[0096] The prepared hard coating liquid was applied to the surface of the primer layer on both sides of the lens substrate by spraying. The mixture was pre-cured by heating in an oven with an internal ambient temperature of 75°C for 20 minutes. Then, the internal ambient temperature of the oven was raised to 110°C and heated at the same temperature for 2 hours for formal curing, thus forming a hard coating on both sides of the lens substrate.

[0097] Inorganic layer (multi-layer anti-reflective film)

[0098] Next, the lens substrate with the aforementioned hard coating is placed in a vacuum evaporation apparatus, and a multilayer antireflective film (total thickness: approximately 400–600 nm) is formed on the surface of the hard coating by vacuum evaporation, consisting of eight alternating layers of SiO2 and ZrO2. The SiO2 layers are vapor-deposited films formed using silicon oxide as the vapor deposition material, and the ZrO2 layers are vapor-deposited films formed using zirconium oxide as the vapor deposition material. Each vapor deposition material is composed solely of the described oxides, except for unavoidable impurities.

[0099] Through the above processes, eyeglass lenses are manufactured with λ / 4 layer (film thickness 0.18μm), primer layer (film thickness 0.70μm), hard coating layer (film thickness 2.30μm), and multi-layer anti-reflective film on both sides of the lens substrate.

[0100] [Examples 1-4, 7-9]

[0101] In Examples 1 and 2, which are listed as “λ / 4 layer” in the “Metal-containing layer” column of Table 1, the λ / 4 layer liquid contains the metal-containing components shown in Table 1 at the content rate shown in Table 1 relative to the total 100% by mass of the λ / 4 layer liquid (excluding solvent). Otherwise, the spectacle lens is made using the method described in Reference Lens 1.

[0102] In Examples 3 and 4, where “primer layer” is listed in the “metal-containing layer” column of Table 1, the primer liquid contains the metal-containing components shown in Table 1 at the content rate shown in Table 1 relative to the total components (excluding solvents) of the primer liquid in 100% by mass. Otherwise, the spectacle lens is made using the method described in Reference Lens 1.

[0103] In Examples 7 and 8, where “hard coating” is listed in the “metal-containing layer” column of Table 1, the hard coating liquid contains the metal-containing components shown in Table 1 at a content rate shown in Table 1 relative to the total 100% by mass of the hard coating liquid. Otherwise, the spectacle lens is made using the method described in Reference Lens 1.

[0104] [Reference Lens 2]

[0105] A hard coating solution was prepared by mixing 44 parts by mass of silica particles, 39 parts by mass of a silane coupling agent (KBM-403 manufactured by Shin-Etsu Chemical Industry Co., Ltd., γ-glycidoxypropyltrimethoxysilane), and 17 parts by mass of a multifunctional epoxy compound (Denacol EX-321 manufactured by Nagase Chemical Co., Ltd., trimethylolpropane polyglycidyl ether). Otherwise, spectacle lenses were manufactured using the method described in Reference Lens 1.

[0106] [Examples 5 and 6]

[0107] The hard coating liquid contains the metal-containing components shown in Table 1 at a content rate shown in Table 1 relative to the total 100% by mass of the hard coating liquid. Otherwise, the spectacle lens is made using the method described in Reference Lens 2.

[0108] [Antibacterial test]

[0109] Antimicrobial tests were conducted in accordance with JIS Z 2801:2012. Reference lens 1 was used as the reference sample in Examples 1-4 and 7-9, and reference lens 2 was used as the reference sample in Examples 6 and 7.

[0110] The antimicrobial evaluation results shown in the "Initial" column of Table 1 are the results of antimicrobial evaluation of test pieces cut from spectacle lenses that have never undergone lightfastness and water resistance tests, using the following method.

[0111] Regarding the lightfastness of the antimicrobial properties shown in Table 1, the lightfastness test was performed on test pieces cut from each spectacle lens according to Category 1 of the lightfastness test section of the SIAA (Association for Antimicrobial Products Technology) Continuous Testing Method (2018 edition), and then the antimicrobial properties were evaluated using the following methods.

[0112] Regarding the water resistance of antimicrobial properties, the water resistance test is performed on test pieces cut from each spectacle lens, according to Category 1 of the water resistance test section of the SIAA (Institute for Antimicrobial Technology) Continuous Testing Method (2018 edition), and then the antimicrobial properties are evaluated using the following methods.

[0113] Place 50mm × 50mm test pieces (test pieces cut from each spectacle lens in the examples and their reference samples) into a sterilized petri dish, then add 0.4ml of solution containing 1.0 × 10 5 ~4.0×10 5 A drop of bacterial suspension of one test bacterium (Staphylococcus aureus or Escherichia coli) is placed in the center of the test slide, which is then covered with a polyethylene film cut into 40mm × 40mm pieces. After incubating the petri dish at a relative humidity of over 90% for 24 hours, the bacterial concentration per 1cm is measured. 2 The number of viable bacteria was used to calculate the following antibacterial activity values.

[0114] Antibacterial activity value = Ut - At ≥ 2.0

[0115] Ut: Per 1cm after 24 hours of incubation of unprocessed test specimens (reference sample) 2 The average of the logarithmic values ​​of the viable bacteria count

[0116] At: Antibacterial processing test piece (example sample) incubated for 24 hours, per 1cm 2 The average of the logarithmic values ​​of the viable bacteria count

[0117] The SIAA (Symmetric Association for Antimicrobial Products) stipulates that an antimicrobial activity value of 2 or higher indicates that the product has an antimicrobial effect. Therefore, the antimicrobial properties of each eyeglass lens are determined based on the antimicrobial activity value calculated above, according to the following criteria.

[0118] OK: Antibacterial activity value is above 2.0

[0119] NG: Antibacterial activity value less than 2.0

[0120] [Table 1]

[0121]

[0122] The results shown in Table 1 confirm that the spectacle lenses of Examples 1 to 9 exhibit excellent antibacterial properties, light resistance, and water resistance.

[0123] [Evaluation regarding the combined use of silver-containing and platinum-containing components]

[0124] <Evaluation on the inhibition of yellowing>

[0125] The platinum content was changed to 0.008% by mass, 0.010% by mass, 0.020% by mass, 0.050% by mass, and 0.100% by mass. Otherwise, spectacle lenses with different platinum content were made using the method described in Example 5.

[0126] The YI value (initial YI value) of each manufactured spectacle lens was measured.

[0127] Next, the eyeglass lenses were placed in a QUV (Quick UV) accelerated weathering tester manufactured by Q-Lab for 4 hours of 0.20W ultraviolet irradiation, followed by 4 hours in a high humidity environment (90% relative humidity). This was considered one cycle, and the cycle was repeated 21 times before the YI value (YI value after QUV) was measured.

[0128] The YI value was determined using the following method.

[0129] The perpendicular incident reflection spectral characteristics at the optical center of the object-side surface (convex side) of the spectacle lens are measured from the object side. Using the measured results of the perpendicular incident transmission spectral characteristics obtained in this way, the YI value is calculated according to JIS K7373:2006. Specifically, based on the transmission spectrum obtained by measuring the perpendicular incident transmission spectral characteristics, X, Y, and Z are calculated according to Equation (3) of JIS Z8701:1999, and the YI value for the D65 light source is calculated using the calculation formula in Section 6.1 of JIS K 7373:2006.

[0130] For the aforementioned spectacle lenses containing varying amounts of silver and platinum components, ΔYI was calculated as: ΔYI = QUV-tested YI value - initial YI value. The YI value is an indicator of yellowing; in other words, the smaller the ΔYI value, the less yellowing occurs after the QUV accelerated weathering test.

[0131] Figure 1 This is a graph obtained by plotting ΔYI relative to the content of platinum-containing components. (From...) Figure 1 It can be confirmed that the more platinum a spectacle lens contains, the smaller the value of ΔYI, meaning that yellowing is suppressed in spectacle lenses containing silver.

[0132] <Evaluation of Membrane Performance>

[0133] The platinum content was changed to 0.008% by mass, 0.010% by mass, 0.020% by mass, 0.050% by mass, and 0.100% by mass. Otherwise, spectacle lenses with different platinum content were made using the method described in Example 7.

[0134] For each manufactured spectacle lens, the various items shown in Table 2 were evaluated using the following methods. The evaluation results shown in Table 2 confirm that the film performance did not decrease with the addition of platinum components or with increasing amounts of platinum.

[0135] (Initial fit)

[0136] The fit was evaluated based on JIS K5600-5-6 (ISO 2409:1992). Specifically, after etching a 10×10 grid on the surface of each eyeglass lens, a three-stage peel test was performed using transparent tape, and the remaining squares out of 100 were counted.

[0137] (Initial abrasion resistance)

[0138] A 1kg load of steel wool #0000 (manufactured by Japan Steel Wool Co., Ltd.) was applied back and forth 20 times to the surface of the spectacle lens, and the ease of surface damage was visually assessed. The judgment criteria are as follows. Additionally, "UA-A" in Table 2 indicates that, among the results of abrasion resistance evaluation of multiple spectacle lenses manufactured using the same method, a very small number of lenses received a judgment of A, while the remaining lenses received a judgment of UA.

[0139] UA: Almost no damage

[0140] A: There are 1 to 10 injuries.

[0141] B: There are 11 to 30 injuries.

[0142] C: The surface is blurry and unclear.

[0143] (Sealing and abrasion resistance after constant temperature and humidity test)

[0144] After storing the spectacle lenses at 40°C and 90% relative humidity for 168 hours, the fit and abrasion resistance of the spectacle lenses were evaluated using the method described above.

[0145] (Sealing and abrasion resistance after soaking in warm water)

[0146] After immersing the spectacle lenses in warm water at 50°C for 48 hours under constant temperature and humidity conditions, the above method was used to evaluate the lens's fit and abrasion resistance.

[0147] (Seam tightness and abrasion resistance after QUV accelerated weathering test)

[0148] After irradiating the eyeglass lenses with 0.20W ultraviolet light for 4 hours in a QUV ultraviolet fluorescent tube accelerated weathering tester manufactured by Q-Lab, they were placed in a high humidity environment (90% relative humidity) for 4 hours. This was considered as one cycle. The cycle was repeated 21 times, and the fit was evaluated using the above method.

[0149] [Table 2]
