Description

Technical Field

[0001] This disclosure relates to a surface layer with excellent processability and stain resistance, an optical component having the surface layer, and eyeglasses having the optical component.

[0002] Furthermore, this disclosure also relates to a surface layer forming material for forming a surface layer with excellent processability and antifouling properties, a surface layer formed using the surface layer forming material, an optical component having the surface layer, and eyeglasses having the optical component. Background Technology

[0003] To suppress light reflection, optical components such as anti-reflective films, filters, optical lenses, and eyeglass lenses are generally made of inorganic materials. Anti-reflective films formed from inorganic materials have high surface free energy. Due to this high surface free energy, fingerprints, sebum, sweat, cosmetics, and other dirt often adhere to them through human use. Furthermore, this adhered dirt is difficult to remove. As a means to solve the problem of dirt adhesion and removal, patent documents 1 and 2 propose a technology that endows the surface of optical components with properties that make it difficult for dirt to adhere, and even if dirt does adhere, it is difficult to remove.

[0004] However, optical components with surfaces endowed with properties that make it difficult for dirt to adhere and even if dirt does adhere, and which are difficult to remove (hereinafter referred to as "anti-fouling properties"), have low friction and slippery surfaces. Therefore, when processing the shape of the optical components, there is a problem that they are difficult to fix stably and are difficult to process.

[0005] To address the aforementioned issues, Patent Document 3 discloses a protective film formed by a coating liquid on an oleophobic coating film. This protective film contains a resin composed of an organic compound, inorganic oxide particles, and an organosilicon compound or its hydrolysate represented by a prescribed general formula as active ingredients. By setting the composition ratio of the resin composed of an organic compound to the inorganic oxide particles and the content of the organosilicon compound or its hydrolysate represented by the prescribed general formula within a prescribed range, an eyeglass lens can be edged using the same holding method as conventional eyeglass lenses, even with an oleophobic coating film.

[0006] Furthermore, Patent Document 4 discloses an eyeglass lens in which the anti-fouling layer is formed by two or more silane compounds, each of which is a fluorinated silane compound, and the surface of the lens formed by the two or more silane compounds as individual components has a maximum kinetic friction coefficient of more than 1.4 times the minimum kinetic friction coefficient. This allows the lens surface to be reduced to a degree that allows for molding without compromising the excellent anti-fouling effect of the anti-fouling layer.

[0034] Hereinafter, preferred embodiments are described to illustrate embodiments of the surface layer, optical component having the surface layer, eyeglasses having the optical component, and surface layer forming material of the present disclosure. Furthermore, the present disclosure is not limited to the following embodiments.

[0035] Furthermore, in this disclosure, unless otherwise specified, the expressions "XX or above, YY or below" or "XX to YY" indicating a numerical range refer to a numerical range that includes both the lower and upper limits as endpoints. Moreover, when describing numerical ranges in stages, the upper and lower limits of each numerical range can be arbitrarily combined.

[0036] According to this disclosure, by maintaining a high frictional force when applying a high load to the surface layer of the base material or optical component, slippage is suppressed, allowing the base material or optical component to be stably fixed during processing. Furthermore, during daily use by the user, the frictional force decreases within the load range applied to the surface layer of the base material or optical component, and anti-fouling properties are exhibited. As a result, a surface layer that simultaneously achieves processability and anti-fouling properties, an optical component having the surface layer, and eyeglasses having the optical component can be provided. Additionally, a surface layer forming material that imparts the above-mentioned properties to the surface layer can also be provided.

[0037] Regarding the mechanism by which the surface layer involved in this disclosure and the optical component having the surface layer simultaneously achieve stability and anti-fouling properties during processing, the inventors believe the following reasons apply.

[0038] As component A in the surface layer, a compound having a fluorine-containing organic site is selected. Furthermore, as component B, a compound having an organic site is selected, wherein the organic site has at least one bond selected from the group consisting of an unsaturated hydrocarbon bond, a carbon-oxygen double bond, and a carbon-nitrogen double bond.

[0039] Because component A has fluorinated organic sites, it exhibits antifouling properties, but tends to have low friction when a load is applied. Furthermore, because component B has organic sites with at least one bond selected from the group consisting of unsaturated hydrocarbon bonds, carbon-oxygen double bonds, and carbon-nitrogen double bonds, it is less prone to deformation even under load compared to component A, and tends to have high friction.

[0040] Therefore, when a surface layer containing at least components A and B comes into contact with an object, under high loads, component B is less prone to deformation than component A, and the proportion of component B in contact with the object increases, thus resulting in high friction.

[0041] Based on this, by adjusting the composition ratio of component B to component A in the surface layer to a specified range, high anti-fouling properties can be obtained when the surface layer comes into contact with an object under low load.

[0042] "Surface layer" refers to the interface that is in contact with the base material and with a solid, liquid, or gas. That is, in this specification, "surface layer" refers to the surface of the base material, and this specification also discloses base materials having such a surface.

[0043] As a base material, any material can be used as long as it is a solid and can form the base layer 12, surface layer 13, intermediate layer 14 or hard coating layer 15 described later, but preferably a film made of glass, ceramic, resin or metal or glass, resin, etc.

[0044] An optical component is an optical component having a base material having the aforementioned surface layer. Examples of such optical components include filters, optical lenses, spectacle lenses, photographic lenses, cover glass for displays, touch panels for displays, and various films.

[0045] Eyeglasses are eyeglasses that have the aforementioned optical components. The term "eyeglasses" encompasses all devices worn around the eyes, and is not limited to conventional vision correction eyeglasses, but includes plano glasses, protective goggles, head-mounted displays, sunglasses, and smart glass, among others.

[0046] The following describes component A as involved in this disclosure.

The fluorinated organic site is preferably selected from at least one site selected from the group consisting of a fluoroalkyl site, a fluoroalkyl ether site, a fluoropolyether site, a vinylidene fluoride site, and a perfluoropolyether site, and more preferably component A has a perfluoropolyether site.

[0064] [Table 2]

[0066]

[0067] In the table, Me represents methyl and Et represents ethyl.

[0068] The following describes component B as covered in this disclosure.

Preferably, component B has an organic site having an unsaturated hydrocarbon bond derived from at least one compound selected from the group consisting of 1,2-polybutadiene, 1,4-polybutadiene, 1,2-polyisoprene, 1,4-polyisoprene, 1,2-polychlorobutadiene, and 1,4-polychlorobutadiene.

[0070] Furthermore, it is also preferred that component B has a polyolefin with an organic site on its side chain, the organic site having at least one bond selected from the group consisting of unsaturated hydrocarbon bonds, carbon and oxygen double bonds, and carbon and nitrogen double bonds.

[0071] Specifically, component B is, for example, an alkyl compound having a structure represented by the following general formula (2).

[0072] R3-Y-R4 (2)

[0073] Here, "an organic site having at least one bond selected from the group consisting of unsaturated hydrocarbon bonds, carbon and oxygen double bonds, and carbon and nitrogen double bonds" means, in the case of component B being a compound having a structure represented by the above general formula (2), the site represented by Y in the above general formula (2).

[0074] The region represented by Y in the above general formula (2) includes one or more regions containing at least one bond selected from the group consisting of unsaturated hydrocarbon bonds, carbon-oxygen double bonds, and carbon-nitrogen double bonds shown in Table 3. Furthermore, the unsaturated hydrocarbon bonds, carbon-oxygen double bonds, and carbon-nitrogen double bonds may have only one or more of any one type of bond, or may be a combination of two or more types of bonds. In addition, regions that do not contain unsaturated hydrocarbon bonds, as shown in Table 3, may be further combined.

[0075] [Table 3]

[0076]

[0077] In Table 3, i, j1, j2, j3, j4, and j5 preferably satisfy 32≤i×(j1+j2+j3+j4+j5)≤180, more preferably 40≤i×(j1+j2+j3+j4+j5)≤150, and even more preferably 50≤i×(j1+j2+j3+j4+j5)≤120.

[0078] In Table 3, i is an integer greater than or equal to 1, and can have different values ​​for each part.

[0079] In Table 3, j1, j2, j3, j4, and j5 are each an independent integer greater than or equal to 0. That is, j1, j2, j3, j4, and j5 in Table 3 can each have a different value in each part.

[0080] Here, j1, j2, j3, j4 and j5 being 0 indicates that the various parts recorded in Table 3 are not included in the parts represented by Y in Equation (2).

[0081] As long as it is within the acceptable range of i×(j1+j2+j3+j4+j5) above, a side chain consisting of a site that branches in the middle of the molecular chain and has at least one bond selected from the group consisting of unsaturated hydrocarbon bonds, carbon-oxygen double bonds, and carbon-nitrogen double bonds can also exist in the site represented by Y.

[0087]

[0088] In addition, specific examples of component B include the compounds shown in Table 5, but are not limited to these compounds.

[0089] [Table 5]

[0090] Table 5

[0091]

[0092] The compounds shown in Table 5 are modified polyolefins in which a portion of the side chain is substituted at one of the alkyl groups having an unsaturated hydrocarbon bond, a carbon-oxygen double bond, or a carbon-nitrogen double bond. Examples of substituted sites include imine, ethylene, carboxylic acid, ketene, and isocyanate sites.

[0093] Regarding the composition ratio of component B to component A in the surface layer of this disclosure, the peak intensity of component A when measured using a micro Raman spectrometer is P. A The peak intensity originating from component B is P. B P at time B / P A The value can be expressed as 0.15 to 0.80. Furthermore, the composition ratio of component B to component A in the surface layer of this disclosure can be adjusted by the mass ratio of component B to component A in the surface layer forming material of this disclosure. This composition ratio is preferably 0.20 to 0.60, more preferably 0.20 to 0.50.

[0094] When the ratio of component B to component A is less than 0.15, even if it exhibits anti-fouling properties, the frictional force does not increase under high loads during processing, and the sliding property is not suppressed, making the processing of the base material difficult. Furthermore, when the ratio of component B to component A is greater than 0.80, the frictional force becomes high even within the range of everyday user loads, not only reducing the anti-fouling properties but also creating difficulties in user experience, such as the cloth getting stuck when wiping away dirt.

[0095] The composition ratio of component B relative to component A can be obtained by the following method.

[0096] First, the region within the surface layer that will be measured by the micro-Raman spectrometer is determined. This region is determined by the magnification of the objective lens and the wavelength and aperture of the excitation laser. This determined region will be referred to below as the "measurement region".

[0097] Next, the measurement area is irradiated with an excitation laser, and the resulting scattered light is measured to obtain the Raman spectrum. The measurement conditions are as follows.

[0098] • Measuring apparatus: Micro Raman spectrometer manufactured by Thermo Fisher Scientific

[0099] • Objective lens magnification: 10x

[0100] • Excitation laser wavelength: 532nm

[0101] • Aperture: 25μm

[0102] • Measurement area: 2μm

[0103] The peaks in the obtained Raman spectrum originating from CF bonds are taken as peaks originating from component A, and the peak intensity of these peaks is taken as P. A Furthermore, peaks in the obtained Raman spectra originating from C=C, C=O, or C=N bonds are considered to originate from component B, and the peak intensity of these peaks is taken as P. B .

[0104] The frictional force, measured at a load of 14 kgf and a frictional speed of 2.5 mm / s applied to the surface layer, is taken as X.

[0105] When the frictional force Y is measured using a load of 70 kgf applied to the surface layer and a frictional speed of 2.5 mm / s,

[0106] The change ratio of friction force, expressed as (YX) / X×100, is preferably 50% to 700%, more preferably 95% to 680%.

[0107] This change ratio can be controlled by the types of component A, the types of component B, and the composition ratio of component B relative to component A.

[0108] Without impairing the effectiveness of this disclosure, the surface layer of this disclosure may contain any compound other than component A and component B.

[0109] First Implementation Method

[0110] Figure 1 This is a schematic diagram illustrating the structure of a first embodiment of the surface layer, and shows a structural example of a base layer formed on a substrate, upon which the surface layer is formed.

[0111] exist Figure 1 In this structure, a base layer 12 exists on the base material 11, and a surface layer 13 is formed on the base layer 12.

[0112] also, Figure 1 It is a diagram that simulates the structure of the surface layer, and is not a diagram that represents the actual thickness of the base material 11, the base layer 12 and the surface layer 13 at the correct ratio.

[0113] (Material 11)

[0114] The base material 11 is a solid material, and it can be used to form a base layer 12, a surface layer 13, or an intermediate layer 14 or a hard coating layer 15 as described later. Examples include films made of glass, ceramics, resin, or metal, or films made of glass, resin, etc. When the above-mentioned materials are used as the base material for optical components having the surface layer of this disclosure, the base material is preferably a material that can transmit visible light or light of a specific wavelength.

[0115] There are no particular restrictions on the thickness of the base material; it can be set appropriately according to the application.

[0116] (Basal layer 12)

[0117] A base layer can be formed as needed. The base layer 12 is the layer that forms the base for the surface layer 13 and ensures good adhesion between the base material 11 and the surface layer 13.

[0118] In this embodiment, in order to further improve the adhesion between the base material 11 and the surface layer 13, a base layer 12 is formed on the base material 11, and the surface layer 13 is formed on the base layer 12. Furthermore, there are no particular limitations on the method for forming the base layer, but vapor deposition, immersion, coating, spraying, spin coating, etc. can be listed.

[0119] There are no particular restrictions on the thickness of the substrate 12, but it is 2nm to 150nm, preferably 5nm to 125nm.

[0120] The material forming the base layer 12 is preferably a substance having hydroxyl groups on its surface. Examples include metal oxides such as SiO2 and Al2O3, and alkyl compounds having hydroxyl groups on their surfaces.

[0121] (Surface layer 13)

[0122] Surface layer 13 is the surface layer of the present disclosure as described above.

[0123] There are no particular limitations on the thickness of the surface layer 13, but it is preferably 4nm to 20nm. When the thickness is above 4nm, sufficient anti-fouling properties can be obtained, and when the thickness is below 20nm, good transparency is achieved.

[0124] Second Implementation Method

[0125] Figure 2 This is a schematic diagram illustrating the structure of the second embodiment of the surface layer, showing an example of a structure in which an intermediate layer is formed on a base material, a base layer is formed on the intermediate layer, and a surface layer is formed on the base layer.

[0126] exist Figure 2 In this process, an intermediate layer 14 is formed on the base material 11, consisting of alternating intermediate layers 14a and 14c with low refractive index materials and intermediate layers 14b and 14d with high refractive index materials. A surface layer 13 is formed on the base layer 12 disposed on the intermediate layer 14.

[0127] also, Figure 2 It is a diagram that simulates the structure of the surface layer, and is not a diagram that represents the actual thickness of the base material 11, intermediate layer 14, base layer 12 and surface layer 13 at the correct ratio.

[0128] (Middle layer 14)

[0129] like Figure 2 As shown, in the intermediate layer 14, counting from the side of the parent material 11, the odd-numbered intermediate layers 14a and 14c are made of low refractive index material, and the even-numbered intermediate layers 14b and 14d are made of high refractive index material.

[0130] Furthermore, in this embodiment, the base layer 12 is also made of a low-refractive-index material and is laminated on the intermediate layer 14, working together with the intermediate layer 14 to perform anti-reflective functions. In this embodiment, as an example, the intermediate layer 14 has four layers, and the base layer 12 is formed on top of the intermediate layer 14d, which has a high-refractive-index material; therefore, the base layer 12 is preferably made of a low-refractive-index material. Furthermore, for example, if the intermediate layer 14 has two layers and the base layer 12 is formed on top of the intermediate layer 14b, which has a high-refractive-index material, the base layer 12 is preferably made of a low-refractive-index material.

[0131] Furthermore, the intermediate layer 14 is not limited to this embodiment, and layers made of medium refractive index material may also be appropriately stacked.

[0132] Examples of low refractive index materials include SiO2 (silicon dioxide) and SiO2 with added Al2O3 (silicon dioxide with added alumina). However, low refractive index materials are not limited to these.

[0133] Examples of high refractive index materials include titanium oxide-lanthanide oxide hybrids containing aluminum oxide, titanium oxide, other mixed oxides with titanium oxide as the main component, zirconium oxide, mixed materials with zirconium oxide as the main component, niobium oxide, mixed materials with niobium oxide as the main component, tantalum oxide, mixed materials with tantalum oxide as the main component, tungsten oxide, and mixed materials with tungsten oxide as the main component. However, high refractive index materials are not limited to these.

[0134] Examples of medium refractive index materials include alumina, other mixed compounds with alumina as the main component, magnesium oxide, other mixed compounds with magnesium oxide as the main component, yttrium fluoride, and cerium fluoride. However, medium refractive index materials are not limited to these.

[0135] Regarding intermediate layer 14 and the layers constituting intermediate layer 14 ( Figure 2 The thickness of the intermediate layer 14 (14a, 14b, 14c, 14d) is not particularly limited, but for example, the thickness of each layer constituting the intermediate layer 14 is 10nm to 200nm, and the necessary number of layers can be stacked to form the intermediate layer 14.

[0136] Furthermore, although the intermediate layer 14 in this embodiment has a 4-layer structure, this disclosure is not limited to this, and the number of layers can be arbitrary.

[0137] Furthermore, although in this embodiment, as described above, an intermediate layer 14 is provided as part of an antireflective film formed by alternating layers of low-refractive-index and high-refractive-index layers, this disclosure is not limited thereto.

However, this is not a limitation, and the number of layers can be arbitrary. In addition, layers made of medium-refractive-index materials can be appropriately laminated.

[0143] Furthermore, as the hard coating 15, melamine resin, polyurethane resin, acrylic resin or a mixture of the above resins, silane compounds, etc., can be used, for example. However, the materials used for the hard coating are not limited to these.

[0144] Furthermore, the optical components shown in the structure of the first embodiment are not limited to eyeglass lenses and can be used for other known applications.

However, this is not a limitation, and the number of layers can be arbitrary. Alternatively, layers composed of medium-refractive-index materials may also be appropriately layered.

[0149] "Glasses"

[0150] Figure 5 This is a schematic diagram illustrating the structure of an eyeglasses using the optical components of this disclosure in one embodiment.

[0151] This embodiment consists of a spectacle lens 31 and a spectacle frame 32, which are optical components of the present disclosure as described above.

[0152] The surface layer forming material disclosed herein is a surface layer forming material containing at least component A and component B, wherein...

[0153] Component A has at least one organic site containing fluorine.

[0154] Component B has an organic site having at least one bond selected from the group consisting of unsaturated hydrocarbon bonds, carbon-oxygen double bonds, and carbon-nitrogen double bonds.

[0155] Furthermore, the mass ratio of component B to component A in the surface layer forming material is 0.15 to 0.80.

[0156] The materials used for forming the surface layer as described in this disclosure are explained.

[0157] The components A and B constituting the surface layer forming material of this disclosure are the same as the components A and B constituting the surface layer of this disclosure.

[0158] In the surface layer forming material of this disclosure, the mass ratio of component A to component B is in the range of 0.15 to 0.80 when the mass of component A is 1. That is, the mass ratio of component B to component A in the surface layer forming material is 0.15 to 0.80. This mass ratio is preferably 0.20 to 0.60, and more preferably 0.20 to 0.50.

[0159] When the mass ratio of component B to component A is less than 0.15, even if the surface layer formed using the surface layer forming material exhibits anti-fouling properties, the frictional force under high loads will not increase during the processing of the base material or optical component having this surface layer, and the sliding property will not be suppressed, thus making the processing of the base material or optical component difficult. Furthermore, when the mass ratio of component B to component A is greater than 0.80, the frictional force becomes high even within the range of daily user loads. This not only reduces the anti-fouling properties of the surface layer formed using the surface layer forming material but also creates difficulties in user experience, such as the cloth getting stuck when wiping away dirt.

[0160] The mass ratio of component B to component A in the surface layer forming material can be determined using liquid chromatography mass analysis. Alternatively, it can be determined using the mass values ​​of component A and component B measured by a balance used in the manufacture of the surface layer forming material.

[0161] Example

[0162] The following examples illustrate the present disclosure in more detail, but the present disclosure is not limited to the following examples.

[0163] [Example 1]

[0164] (Fabrication of surface layer forming materials)

[0165] The compound (B-19) listed in Table 2, which is component A, and the compound (a-4) listed in Table 4, which is component B, are blended in a metal container at a mass ratio of component B to component A of 0.20 to obtain surface layer forming material 1.

[0166] (Preparation of the base layer)

[0167] A 10 nm thick substrate layer 12 composed of SiO2 was formed on a 3 mm thick borosilicate glass substrate 11 using a vacuum evaporation apparatus (dome diameter Φ900 mm, evaporation distance 890 mm) via evaporation. The thickness of the substrate layer 12 was measured using a spectroscopic ellipsometer (JA WOOLLAM ESM300).

[0168] (Surface layer fabrication)

[0169] The surface layer 13 of this disclosure, composed of the surface layer forming material 1, was formed on the substrate layer 12 using a vacuum evaporation apparatus (dome diameter Φ900mm, evaporation distance 890mm) by evaporation, thereby fabricating the optical component of Embodiment 1. The thickness of the surface layer 13 was measured to be 10nm using a spectrophotometer (JA WOOLLAM ESM300). Furthermore, when the composition ratio of component B to component A in the obtained surface layer was measured using a micro Raman spectrometer, the mass ratio of component B to component A in the surface layer forming material was also 0.20.

[0170] The structure of the obtained optical component is similar to that of... Figure 1 The optical components of the surface layer shown in this disclosure have the same structure.

[0171] (Evaluation of friction)

[0172] Regarding the surface layer of the manufactured optical component, the friction force of the surface layer is measured according to the following method.

[0173] As the device for measuring friction force, the Triboster 500 automatic friction and wear analysis device manufactured by Kyowa Interface Science Co., Ltd. was used. As the contactor used for measuring friction force, a piece cut to 2mm was used. 2 A rubber pad (3M lens shielding pad) was used, and the frictional force was measured by bringing the rubber pad into contact with the surface layer of the optical component. The applied load of the device was adjusted to 14 kgf and 70 kgf on the surface layer during the test. The test was conducted at a frictional speed of 2.5 mm / s. The results are shown in Table 6.

[0174] (Evaluation of antifouling properties)

[0175] Regarding the surface layer of the manufactured optical components, the antifouling properties of the surface layer are evaluated according to the following method.

[0176] As indicators of stain resistance, the elasticity and ease of erasing of the highlighter ink were used as evaluation criteria, and the evaluation was conducted based on the following standards. The results are shown in Table 6.

[0177] (Evaluation Criteria)

[0178] A: When the pen tip is applied to the surface layer, the ink sphericalizes and bounces off in less than 2 seconds, and can be easily wiped off with transparent paper.

[0179] B: After the pen tip adheres to the surface layer, the ink takes 2 to 5 seconds to turn into a ball and bounce off, and can be wiped off with transparent paper.

[0180] C: After the pen tip adheres to the surface layer, the ink will not bounce off even if it exceeds 5 seconds, and it cannot be wiped off without vigorous wiping with transparent paper.
