[0007] As used herein, the term "monovalent organic group" refers to a monovalent group containing carbon. The monovalent organic group is not particularly limited, but may be a hydrocarbon group or a derivative thereof. A hydrocarbon group derivative refers to a group having one or more N, O, S, Si, amide, sulfonyl, siloxane, carbonyl, carbonyloxy, etc. at the end or in the molecular chain of the hydrocarbon group. Note that when simply referring to an "organic group," it refers to a monovalent organic group. Furthermore, the term "divalent organic group" refers to a divalent group containing carbon. Examples of such divalent organic groups include divalent groups in which one more hydrogen atom has been eliminated from an organic group. Similarly, a trivalent or higher organic group refers to a group in which a predetermined number of hydrogen atoms have been eliminated from an organic group.

[0008] As used herein, the term "hydrocarbon group" refers to a group containing carbon and hydrogen, which is a group obtained by removing a hydrogen atom from a hydrocarbon. Such hydrocarbon groups include, but are not limited to, C １－３０ Examples of hydrocarbon groups include aliphatic hydrocarbon groups and aromatic hydrocarbon groups. The "aliphatic hydrocarbon group" may be linear, branched, or cyclic, and may be saturated or unsaturated. The hydrocarbon group may contain one or more ring structures. The hydrocarbon group may be substituted with one or more substituents.

[0009] As used herein, the substituent of the "hydrocarbon group" is not particularly limited, but examples thereof include a halogen atom, a C １－６ Alkyl group, C ２－６ Alkenyl group, C ２－６ Alkynyl group, C ３－１０ Cycloalkyl group, C ３－１０ Unsaturated cycloalkyl groups, 5- to 10-membered heterocyclyl groups, 5- to 10-membered unsaturated heterocyclyl groups, C ６－１０ Examples include one or more groups selected from aryl groups and 5- to 10-membered heteroaryl groups.

[0010] As used herein, the term "hydrolyzable group" refers to a group that can undergo a hydrolysis reaction, i.e., a group that can be removed from the main skeleton of a compound by a hydrolysis reaction. Examples of hydrolyzable groups include -OR ｈ , -OCOR ｈ , —O—N═CR ｈ ２ , -NR ｈ ２ , -NHR ｈ or —NCO (wherein R ｈ represents a substituted or unsubstituted alkyl group having 1 to 4 carbon atoms), and preferably —OR ｈ (i.e., an alkoxy group). ｈ Examples of the alkyl group include unsubstituted alkyl groups such as methyl, ethyl, propyl, isopropyl, n-butyl, and isobutyl; and substituted alkyl groups such as chloromethyl. Among these, alkyl groups, particularly unsubstituted alkyl groups, are preferred, with methyl and ethyl groups being more preferred.

[0011] The laminate of the present disclosure includes a substrate and a water-repellent layer located on the substrate, wherein the nitrogen concentration on the surface of the water-repellent layer is 0.01 atomic % or more and 10 atomic % or less, and the fluorine concentration on the surface of the water-repellent layer is less than 5 atomic %.

[0012] [Substrate] The type of substrate included in the laminate of the present disclosure is not particularly limited, and may be composed of any appropriate material, such as glass, resin (which may be a natural or synthetic resin, for example, a general plastic material), metal, ceramics, semiconductors (silicon, germanium, etc.), fibers (woven fabrics, nonwoven fabrics, etc.), fur, leather, wood, ceramics, stone, etc., building materials, etc., sanitary products, etc.

[0013] For example, when the article to be manufactured is an optical component, the material constituting the surface of the substrate may be a material for optical components, such as glass or transparent plastic. When the article to be manufactured is an optical component, some layer (or film), such as a hard coat layer or an anti-reflection layer, may be formed on the surface (outermost layer) of the substrate. The anti-reflection layer may be either a single-layer anti-reflection layer or a multi-layer anti-reflection layer. Examples of inorganic materials that can be used for the anti-reflection layer include SiO２ , SiO, ZrO ２ , TiO ２ , TiO, Ti ２ O ３ , Ti ２ O ５ , Al ２ O ３ , Ta ２ O ５ , Ta ３ O ５ , Nb ２ O ５ , HfO ２ , Si ３ N ４ , CeO ２ , MgO, Y ２ O ３ , SnO ２ , MgF ２ , W.O. ３ These inorganic materials may be used alone or in combination of two or more (for example, as a mixture). When a multi-layer antireflection layer is formed, the outermost layer may contain SiO ２ and / or SiO is preferably used. When the article to be manufactured is an optical glass component for a touch panel, a transparent electrode, for example, a thin film using indium tin oxide (ITO) or indium zinc oxide, may be provided on a portion of the surface of the substrate (glass). Furthermore, the substrate may have an insulating layer, an adhesive layer, a protective layer, a decorative frame layer (I-CON), an atomization film layer, a hard coating film layer, a polarizing film, a phase difference film, a liquid crystal display module, or the like, depending on its specific specifications.

[0014] The shape of the substrate is not particularly limited and may be, for example, a plate, a film, or other form. The surface region of the substrate on which the water-repellent layer is to be formed may be at least a part of the substrate surface, and may be appropriately determined depending on the use and specific specifications of the article to be manufactured.

[0015] In one embodiment, at least the surface portion of such a substrate may be made of a material that originally contains hydroxyl groups. Examples of such materials include glass, metals (especially base metals), ceramics, semiconductors, and the like, on whose surfaces native oxide or thermal oxide films form. Alternatively, in cases where the presence of hydroxyl groups is insufficient, such as in resins, or in cases where hydroxyl groups are not originally present, some kind of pretreatment can be performed on the substrate to introduce or increase the number of hydroxyl groups on the substrate surface. Examples of such pretreatments include plasma treatment (e.g., corona discharge) and ion beam irradiation. Plasma treatment can introduce or increase hydroxyl groups on the substrate surface, and can also be suitably used to clean the substrate surface (remove foreign matter, etc.). Another example of such pretreatment is a method in which an interfacial adsorbent having carbon-carbon unsaturated bond groups is preliminarily formed in the form of a monomolecular film on the substrate surface by the Langmuir-Blodgett method (LB method) or chemical adsorption method, and then the unsaturated bonds are cleaved in an atmosphere containing oxygen, nitrogen, or the like.

[0016] In another embodiment, the substrate may be one whose surface portion is made of a material containing another reactive group, such as a silicone compound having one or more Si—H groups, or an alkoxysilane.

[0017] In a preferred embodiment, the substrate is glass, and examples of such glass include, but are not limited to, sapphire glass, soda-lime glass, alkali aluminosilicate glass, borosilicate glass, alkali-free glass, crystal glass, quartz glass, crystallized glass, chemically strengthened soda-lime glass, chemically strengthened alkali aluminosilicate glass, and chemically bonded borosilicate glass.

[0018] The thickness of the substrate is not particularly limited, but is, for example, 5 μm or more, preferably 10 μm or more, and more preferably 20 μm or more, and is, for example, 20 mm or less, preferably 10 mm or less, and more preferably 8 mm or less.

[0019] [Water-repellent layer] The water-repellent layer included in the laminate of the present disclosure is located on the substrate. Note that, in the present disclosure, "on the substrate" does not necessarily refer only to an embodiment in which the water-repellent layer is in direct contact with the substrate, but may also refer to an embodiment in which, for example, an intermediate layer is present between the substrate and the water-repellent layer. In a preferred embodiment, the water-repellent layer is located on the surface of the laminate.

[0020] The water-repellent layer included in the laminate of the present disclosure can be formed by applying a surface treatment agent onto the substrate or intermediate layer.

[0021] The water-repellent layer included in the laminate of the present disclosure has a nitrogen concentration of 0.01 atomic % or more and 10 atomic % or less on the surface thereof, and a fluorine concentration of less than 5 atomic %.

[0022] In one embodiment, the nitrogen concentration on the surface of the water-repellent layer is 0.01 atomic % or more and 10 atomic % or less.

[0023] In one embodiment, the fluorine concentration at the surface of the water-repellent layer is less than 5 atomic %. In a more preferred embodiment, the fluorine concentration at the surface of the water-repellent layer is less than 1 atomic %. In an even more preferred embodiment, the fluorine concentration at the surface of the water-repellent layer is less than 0.1 atomic %.

[0024] In a preferred embodiment, the silicon concentration on the surface of the water-repellent layer is 0.1 atomic % or more and 50 atomic % or less.

[0025] In a more preferred embodiment, the silicon concentration on the surface of the water-repellent layer is 15 atomic % or more and 25 atomic % or less.

[0026] The concentrations of each element on the surface of the water-repellent layer can be determined by surface analysis. Examples of methods that can be used for surface analysis include X-ray photoelectron spectroscopy (XPS) and time-of-flight secondary ion mass spectrometry. Typically, XPS analysis is used.

[0027] The XPS analysis apparatus used to measure the elemental concentrations on the water-repellent layer surface can be a PHI5000 VersaProbe II manufactured by ULVAC-PHI, Inc. The XPS analysis conditions include a monochromated AlKα X-ray source at 25 W, a photoelectron detection area of ​​1400 μm × 300 μm, a photoelectron detection angle in the range of 20 to 90 degrees (e.g., 20, 45, and 90 degrees), a pass energy of 23.5 eV, and Ar ions as sputtered ions. Using the above apparatus and measurement conditions, the concentrations of nitrogen, fluorine, and silicon on the water-repellent layer surface can be determined based on the spectra of the N1s, F1s, and Si2p orbitals.

[0028] Specific measurement methods and conditions may be as follows. The surface of the water-repellent layer treated on the substrate can be subjected to XPS measurement using an X-ray photoelectron spectrometer (XPS, PHI5000VersaProbeII manufactured by ULVAC-PHI, Inc.). Measurement conditions for XPS analysis are, for example, as follows: X-ray source: monochromated AlKα radiation (25 W); Photoelectron detection area: 1400 μm × 300 μm; Photoelectron detection angle: 45 degrees; Pass energy: 23.5 eV; Measurement elements: carbon (C1s) 278 to 298 eV, nitrogen (N1s) 390 to 410 eV, oxygen (O1s) 523 to 543 eV, fluorine (F1s) 680 to 698 eV, silicon (Si2p) 94 to 114 eV

[0029] The atomic ratio corresponding to each element can be calculated from the peak shape and intensity obtained in each region.

[0030] The detection depth can be adjusted appropriately by adjusting the photoelectron detection angle in the XPS analysis. For example, a shallow angle close to 20 degrees can achieve a detection depth of about 3 nm, while a deep angle close to 90 degrees can achieve a detection depth of about 10-odd nm.

[0031] In addition, when silicon derived from the substrate is detected in the composition analysis by XPS analysis, the amount of Si detected in the substrate can be calculated from the detected amount of specific atoms in the substrate, for example, if the substrate is glass, metal atoms (e.g., Al, Na, K, B, Ca, Mg, Sn, etc.) contained in trace amounts, and subtracted from the measurement results, thereby making it possible to distinguish between the silicon concentration derived from the water-repellent layer and the silicon concentration derived from the substrate.

[0032] In one embodiment, when measuring the silicon concentration on the surface of the water-repellent layer, silicon originating from an intermediate layer such as a silicon dioxide layer can be detected. In another embodiment, when measuring the silicon concentration on the surface of the water-repellent layer, silicon originating from an intermediate layer such as a silicon dioxide layer is not detected.

[0033] The nitrogen concentration on the surface of the water-repellent layer is defined as the atomic ratio of the total amount of carbon, nitrogen, oxygen, fluorine, and silicon.

[0034] The fluorine concentration on the surface of the water-repellent layer is defined as the atomic ratio of the total amount of carbon, nitrogen, oxygen, fluorine, and silicon.

[0035] The silicon concentration on the surface of the water-repellent layer is defined as the atomic ratio of the total amount of carbon, nitrogen, oxygen, fluorine, and silicon.

[0036] The nitrogen concentration, fluorine concentration, and silicon concentration can be measured at three different points on the surface of the water-repellent layer, and the average values ​​thereof can be used.

[0517] Examples of the catalyst include acids (e.g., acetic acid, hydrochloric acid, nitric acid, sulfuric acid, phosphoric acid, sulfonic acid, p-toluenesulfonic acid, trifluoroacetic acid, etc.), bases (e.g., sodium hydroxide, potassium hydroxide, ammonia, triethylamine, diethylamine, etc.), transition metals (e.g., Ti, Ni, Sn, Zr, Al, B, Si, Ta, Nb, Mo, W, Cr, Hf, V, etc.), sulfur-containing compounds having an unshared electron pair in the molecular structure, or nitrogen-containing compounds (e.g., sulfoxide compounds, aliphatic amine compounds, aromatic amine compounds, phosphoric acid amide compounds, amide compounds, urea compounds), etc.

[0518] Examples of the aliphatic amine compounds include diethylamine, triethylamine, etc. Examples of the aromatic amine compounds include aniline, pyridine, etc.

[0519] In a preferred embodiment, the transition metal is contained as a transition metal compound represented by M-R (wherein M is a transition metal atom and R is a hydrolyzable group). By using a transition metal compound in which a transition metal is bonded to a hydrolyzable group, the transition metal atom can be contained more efficiently in the water-repellent layer, and the friction durability and chemical resistance of the water-repellent layer can be further improved.

[0520] The hydrolyzable group means a group that can undergo a hydrolysis reaction, similar to the hydrolyzable group in the compound represented by formula (1) or formula (2), that is, a group that can be eliminated from a transition metal atom by a hydrolysis reaction. Examples of the hydrolyzable group include -OR ｍ , -OCOR ｍ , —O—N═CR ｍ ２ , -NR ｍ２ , -NHR ｍ , —NCO, or halogen (wherein R ｍ is a substituted or unsubstituted C １－４ (representing an alkyl group) and the like.

[0521] In a preferred embodiment, the hydrolyzable group is —OR ｍ The use of an alkoxy group as the hydrolyzable group allows the transition metal atom to be more efficiently incorporated into the water-repellent layer, thereby further improving the friction durability and chemical resistance of the water-repellent layer.

[0522] In one embodiment, the hydrolyzable group may be the same as the hydrolyzable group contained in the compound represented by formula (1) or (2). By using the same hydrolyzable group in the silane compound and the transition metal compound, even if the hydrolyzable groups are exchanged with each other, the effect can be reduced.

[0523] In another embodiment, the hydrolyzable group may be different from the hydrolyzable group contained in the compound represented by formula (1) or (2). By making the hydrolyzable groups in the silane compound and the transition metal compound different, the hydrolysis reactivity can be controlled.

[0524] In one embodiment, the hydrolyzable group and the hydrolyzable group contained in the compound represented by formula (1) or (2) may be interchanged in the surface treatment agent.

[0525] In a preferred embodiment, the transition metal compound is Ta(OR ｍ ) ５ (In the formula, R ｍ is a substituted or unsubstituted C １－４ is an alkyl group.), and preferably Ta(OCH ２ CH ３ ) ５ , or Si(OR ｍ ) １－ｍ１ R ｍ’ ｍ１ (In the formula, R ｍ is a substituted or unsubstituted C １－４is an alkyl group, and R ｍ’ is C １－４ is an alkyl group, and m1 is 0 or 1.), and preferably tetraethoxysilane, methyltrimethoxysilane, methyltriethoxysilane, tetraisopropoxysilane, dimethyldiethoxysilane, or dimethyldimethoxysilane.

[0526] The catalyst may be contained in an amount of, for example, 0.0002% by mass or more relative to the entire surface treatment agent. The catalyst is preferably contained in an amount of 0.02% by mass or more, and more preferably 0.04% by mass or more, relative to the entire surface treatment agent. The catalyst may be contained in an amount of, for example, 10% by mass or less, and particularly 1% by mass or less, relative to the entire surface treatment agent. By containing the catalyst at the above-mentioned concentration, the surface treatment agent can contribute to the formation of a water-repellent layer with better durability.

[0527] The content of the catalyst is preferably 0 to 10 mass %, more preferably 0 to 5 mass %, and particularly preferably 0 to 1 mass %, based on the compound represented by formula (1) or the mixture of the compound represented by formula (1) and the compound represented by formula (2).

[0528] The catalyst promotes the hydrolysis and dehydration condensation of the compound represented by formula (1) or (2) above, and promotes the formation of the layer formed by the surface treatment agent.

[0529] In addition to the above, other components include, for example, tetraethoxysilane, methyltrimethoxysilane, 3-aminopropyltrimethoxysilane, 3-glycidoxypropyltrimethoxysilane, methyltriacetoxysilane, and the like.

[0530] In addition to the above components, the surface treatment agent may contain trace amounts of impurities such as Pt, Rh, Ru, 1,3-divinyltetramethyldisiloxane, triphenylphosphine, NaCl, KCl, and silane condensates.

[0531] In one embodiment, the surface treatment agent is for dry coating, preferably vacuum deposition.

[0532] In one embodiment, the surface treatment agent is for a wet coating method, preferably for dip coating.

[0533] The surface treatment agent can be impregnated into a porous material, such as a porous ceramic material or a metal fiber, such as a flocculated steel wool, to form pellets, which can be used for vacuum deposition, for example.

[0534] The water-repellent layer may further have water repellency, oil repellency, stain resistance, waterproofing (preventing water from penetrating into electronic components, etc.), surface slipperiness (or lubricity, e.g., excellent tactile feel against fingers), chemical resistance, etc., depending on the composition of the composition contained therein. Furthermore, the water-repellent layer contained in the laminate of the present disclosure may have both high abrasion resistance and fingerprint wiping properties. For example, the water-repellent properties, such as water repellency, oil repellency, and surface slipperiness, possessed by the water-repellent layer may be retained to a high degree from the pre-abrasion properties even after the layer has been abraded a predetermined number of times.

[0535] The water contact angle of the water-repellent layer may be, for example, 95° or more, or even 100° or more, preferably 103° or more, more preferably 106° or more, or even more preferably 110° or more, and may be, for example, 140° or less, or even 125° or less.

[0536] The above contact angle with water and contact angles with other liquids can be measured by the method described in the examples of this specification.

[0537] The thickness of the water-repellent layer is not particularly limited, but is preferably 15 nm or less, for example, 1 to 15 nm, 1 to 13 nm, or 1 to 10 nm.

[0538] The laminate of the present disclosure can be produced by applying a surface treatment agent containing a compound represented by formula (1) or a mixture of a compound represented by formula (1) and a compound represented by formula (2) to the surface of a substrate (e.g., glass), and then post-treating the resulting mixture as needed to form a layer of a cured product of the compound or mixture (i.e., a water-repellent layer).

[0539] The water-repellent layer can be formed by applying the surface treatment agent to the surface of the substrate so as to coat the surface. The coating method is not particularly limited. For example, a wet coating method or a dry coating method can be used.

[0540] Examples of wet coating methods include dip coating, spin coating, flow coating, spray coating, roll coating, gravure coating, wipe coating, squeegee coating, die coating, ink jet, casting, Langmuir-Blodgett coating, and similar methods.

Specific examples of vapor deposition methods (usually vacuum deposition) include resistance heating, electron beam, high frequency heating using microwaves, etc., ion beam, and similar methods. Specific examples of CVD methods include plasma-CVD, optical CVD, thermal CVD, and similar methods.

[0542] Furthermore, coating by atmospheric pressure plasma method is also possible.

[0544] When the dry coating method is used, the surface treatment agent may be subjected to the dry coating method as it is, or may be diluted with the above-mentioned solvent before being subjected to the dry coating method.

[0545] The water-repellent layer is preferably formed so that the surface treatment agent is present in the layer together with a catalyst for hydrolysis and dehydration condensation. Conveniently, in the case of a wet coating method, the surface treatment agent may be diluted with a solvent, and then a catalyst may be added to the diluted solution of the surface treatment agent immediately before application to the substrate surface.

[0547] The articles of the present disclosure are described below.

[0548] The article of the present disclosure includes the laminate.

[0549] In one embodiment, the article of the present disclosure may include an intermediate layer containing silicon oxide between the glass and the water-repellent layer. By providing such an intermediate layer, adhesion between the glass and the water-repellent layer is improved, and durability is improved.

[0550] In a preferred embodiment, the intermediate layer may contain alkali metal atoms in addition to silicon oxide.

[0551] Examples of the alkali metal atom include lithium, sodium, potassium, etc. The alkali metal atom is preferably sodium.

[0552] The thickness of the intermediate layer is not particularly limited, but is preferably 1 to 200 nm, and particularly preferably 1 to 20 nm. By making the thickness of the intermediate layer equal to or greater than the lower limit of the above range, the effect of the intermediate layer in improving adhesiveness becomes greater.

[0553] The alkali metal atom concentration in the intermediate layer can be measured by various surface analysis devices, such as TOF-SIMS, XPS, and XRF.

[0554] The proportion of alkali metal atoms in the total atoms of the entire intermediate layer can be obtained by XPS depth profile analysis using ion sputtering, which is performed by alternately repeating XPS measurement and surface etching by ion sputtering using an ion gun built into the XPS apparatus.

[0555] The average alkali metal concentration in the region of the intermediate layer that is 1 nm or less deep from the surface in contact with the water-repellent layer is determined by obtaining a depth profile of the alkali metal atom concentration by TOF-SIMS (time-of-flight secondary ion mass spectrometry) depth profile analysis using ion sputtering, and then calculating the average alkali metal atom concentration in the profile. TOF-SIMS depth profile analysis using ion sputtering is performed by alternately repeating TOF-SIMS measurement and surface etching by ion sputtering using an ion gun built into the TOF-SIMS device.

[0556] The article of the present disclosure may be, but is not particularly limited to, an optical member. Examples of optical members include lenses for eyeglasses and the like; front protective plates, anti-reflection plates, polarizing plates, and anti-glare plates for displays such as PDPs and LCDs; touch panel sheets for devices such as mobile phones and personal digital assistants; disc surfaces of optical discs such as Blu-ray (registered trademark) discs, DVD discs, CD-Rs, and MOs; optical fibers; and the display surfaces of watches and clocks.

[0557] The article of the present disclosure may also be a medical device or medical material. The article having a water-repellent layer obtained by the present disclosure may also be an automobile interior or exterior component. Examples of exterior components include windows, light covers, and exterior camera covers. Examples of interior components include instrument panel covers, navigation system touch panels, and decorative interior components.

[0558] The intermediate layer containing silicon oxide can be formed by applying a silicon oxide precursor to the surface of a substrate. When the intermediate layer contains alkali metal atoms, the intermediate layer can be formed by applying a composition containing a silicon oxide precursor and an alkali metal source to the surface of a substrate.

[0559] Examples of the silicon oxide precursor include silicic acid, partial condensates of silicic acid, alkali metal silicates, silane compounds having a hydrolyzable group bonded to a silicon atom, and partial hydrolysis condensates of the silane compounds. Silicic acid and its partial condensates can be converted into silicon oxide by dehydration condensation. Alkali metal silicates can be converted into silicic acid or its partial condensates by the addition of an acid or a cation exchange resin, and the resulting silicic acid or its partial condensates can then be dehydration condensed into silicon oxide. Examples of the hydrolyzable group in a silane compound having a hydrolyzable group bonded to a silicon atom include an alkoxy group and a chlorine atom. The hydrolyzable group in the silane compound can be hydrolyzed to a hydroxyl group, and the resulting silanol compound can be dehydration condensed to form silicon oxide. Examples of silane compounds having a hydrolyzable group bonded to a silicon atom include alkoxysilanes such as tetraalkoxysilanes and alkyltrialkoxysilanes, and tetrachlorosilane.

[0560] Examples of the alkali metal source include alkali metal hydroxides, water-soluble alkali metal salts, etc. Examples of the water-soluble alkali metal salts include alkali metal carbonates, alkali metal hydrogencarbonates, alkali metal hydrochlorides, alkali metal nitrates, etc. As the alkali metal source, alkali metal hydroxides and alkali metal carbonates are preferred.

[0561] Alkali metal silicates can be used as silicon oxide precursors and alkali metal sources. Alkali metal silicates can be converted to silicon oxide via silicic acid, but a small amount of alkali metal may remain in the resulting silicon oxide. Therefore, by adjusting the amount of remaining alkali metal atoms, silicon oxide containing a predetermined amount of alkali metal atoms can be obtained.

[0562] The water-repellent layer included in the article of the present disclosure can have high abrasion resistance as described above. In addition to high abrasion resistance, the water-repellent layer can have water repellency, oil repellency, antifouling properties (for example, preventing adhesion of stains such as fingerprints), waterproof properties (for example, preventing water penetration into electronic components), surface slipperiness (or lubricity, for example, ease of wiping off stains such as fingerprints and excellent tactile feel), chemical resistance, etc., depending on the composition of the surface treatment agent used, and can be suitably used as a functional thin film.

[0563] Therefore, the present disclosure also relates to an optical material having the above-described water-repellent layer as the outermost layer.

[0564] Preferred examples of the optical material include optical materials relating to displays and the like, such as those exemplified below, as well as a wide variety of other optical materials: for example, displays such as cathode ray tubes (CRTs; for example, personal computer monitors), liquid crystal displays, plasma displays, organic EL displays, inorganic thin-film EL dot matrix displays, rear projection displays, vacuum fluorescent displays (VFDs), and field emission displays (FEDs), or protective plates for such displays, or displays whose surfaces have been treated with an anti-reflection film.

[0565] The article of the present disclosure may be, but is not particularly limited to, an optical member. Examples of optical members include lenses for eyeglasses and the like; front protective plates, anti-reflection plates, polarizing plates, and anti-glare plates for displays such as PDPs and LCDs; touch panel sheets for devices such as mobile phones and personal digital assistants; disc surfaces of optical discs such as Blu-ray (registered trademark) discs, DVD discs, CD-Rs, and MOs; optical fibers; and the display surfaces of watches and clocks.

[0566] The article of the present disclosure may also be a medical device or medical material. The article having a layer obtained by the present disclosure may also be an automobile interior or exterior component. Examples of exterior components include windows, light covers, and exterior camera covers. Examples of interior components include instrument panel covers, navigation system touch panels, and decorative interior components.

[0567] The thickness of the layer is not particularly limited. In the case of an optical member, the thickness of the layer may be, for example, in the range of 1 to 50 nm, preferably 1 to 30 nm, and more preferably 1 to 15 nm, from the viewpoints of optical performance, abrasion resistance, and antifouling properties.

[0568] An X-ray photoelectron spectroscopy (XPS) device, such as a PHI5000 VersaProbe II manufactured by ULVAC-PHI, can be used to measure the atomic composition and atomic ratio of the water-repellent layer. The measurement conditions for XPS analysis include a monochromated AlKα X-ray source at 25 W, a photoelectron detection area of ​​1400 μm × 300 μm, a photoelectron detection angle in the range of 20 to 90 degrees (e.g., 20, 45, or 90 degrees), and a pass energy of 23.5 eV. Gas cluster ion beams or Ar ions can be used for sputtering. Using the above-described device and measurement conditions, the peak areas of F1s, C1s, O1s, and Si2p can be observed, and the atomic ratios of fluorine, carbon, oxygen, and silicon can be calculated to determine the composition of the water-repellent layer and intermediate layer.

[0569] Depth analysis can also be performed. Measurement conditions for XPS analysis include using a monochromated AlKα ray at 25 W as the X-ray source, a photoelectron detection area of ​​1400 μm × 300 μm, a photoelectron detection angle in the range of 20 to 90 degrees (e.g., 20, 45, or 90 degrees), and a pass energy of 23.5 eV. Ar ions, gas cluster ions, or C ions can be used as sputtering ions. Sputtering can be performed to etch 1 to 100 nm, and the composition of the coating film at each post-etching depth can be determined.

[0570] The detection depth can be adjusted appropriately by adjusting the photoelectron detection angle in the XPS analysis. For example, a shallow angle close to 20 degrees can achieve a detection depth of about 3 nm, while a deep angle close to 90 degrees can achieve a detection depth of about 10-odd nm.

[0571] The intermediate layer containing silicon oxide can be formed by applying a silicon oxide precursor to the surface of the substrate. When the intermediate layer contains an alkali metal, the intermediate layer can be formed by applying a composition containing a silicon oxide precursor and an alkali metal source to the surface of the substrate.

[0572] Examples of the silicon oxide precursor include silicic acid, partial condensates of silicic acid, alkali metal silicates, silane compounds having a hydrolyzable group bonded to a silicon atom, and partial hydrolysis condensates of the silane compounds. Silicic acid and its partial condensates can be converted into silicon oxide by dehydration condensation. Alkali metal silicates can be converted into silicic acid or its partial condensates by the addition of an acid or a cation exchange resin, and the resulting silicic acid or its partial condensates can then be dehydration condensed into silicon oxide. Examples of the hydrolyzable group in a silane compound having a hydrolyzable group bonded to a silicon atom include an alkoxy group and a chlorine atom. The hydrolyzable group in the silane compound can be hydrolyzed to a hydroxyl group, and the resulting silanol compound can be dehydration condensed to form silicon oxide. Examples of silane compounds having a hydrolyzable group bonded to a silicon atom include alkoxysilanes such as tetraalkoxysilanes and alkyltrialkoxysilanes, and tetrachlorosilane.

[0573] Examples of the alkali metal source include alkali metal hydroxides, water-soluble alkali metal salts, etc. Examples of the water-soluble alkali metal salts include alkali metal carbonates, alkali metal hydrogencarbonates, alkali metal hydrochlorides, alkali metal nitrates, etc. As the alkali metal source, alkali metal hydroxides and alkali metal carbonates are preferred.

[0574] Alkali metal silicates can be used as silicon oxide precursors and alkali metal sources. Alkali metal silicates can be converted to silicon oxide via silicic acid, but a small amount of alkali metal may remain in the resulting silicon oxide. Therefore, by adjusting the amount of the remaining alkali metal, silicon oxide containing a desired amount of alkali metal atoms can be obtained.

[0575] The thickness of the intermediate layer is not particularly limited, but is, for example, in the range of 1 to 50 nm, preferably 1 to 30 nm, more preferably 2 to 15 nm, and even more preferably 3 to 10 nm.

[0576] The compounds, compositions, and articles of the present disclosure have been described in detail above. However, the compounds, compositions, and articles of the present disclosure are not limited to those exemplified above.

[0662] <Preparation of Surface Treatment Agent> Surface treatment agents were prepared as shown in Table 1.

[0663] <Na-Containing Intermediate Layer Forming Material> 2.2 g of sodium hydroxide (manufactured by Fujifilm Wako Pure Chemical Industries, Ltd.) was dissolved in 24 g of distilled water to obtain an 8.4 mass% sodium hydroxide aqueous solution. 24 g of this 8.4 mass% sodium hydroxide aqueous solution was mixed with 20 g of MS gel (MSGELD-100-60A (manufactured by AGC Si-Tech Co., Ltd.)), and the sodium hydroxide aqueous solution was absorbed into the MS gel. The MS gel that had absorbed the sodium hydroxide aqueous solution was dried at 25°C for 8 hours, then molded using a tablet molding machine (4 MPa for 1 minute) and baked at 1,000°C for 1 hour to obtain molded body 1 (pellet).

[0664] (SiO ２ Intermediate layer) The surface treatment agent prepared above was vacuum-deposited onto chemically strengthened glass (Corning Gorilla Glass, thickness 0.7 mm). Specifically, 0.1 g of the surface treatment agent was loaded into a molybdenum boat in a vacuum deposition apparatus, and the inside of the vacuum deposition apparatus was pressurized to a pressure of 3.0 × 10 －３ The chamber was evacuated to a pressure of 100 Pa or less. A silicon dioxide film having a thickness of 5 nm was then formed, and the boat was then heated by resistance heating to form a surface treatment layer (i.e., a water-repellent layer). A heat treatment was then performed in an oven at 150°C for 2 hours, yielding a surface treatment layer.

[0665] (Na-containing SiO ２ Intermediate layer) The surface treatment agent prepared above was vacuum-deposited onto chemically strengthened glass (Corning Gorilla Glass, thickness 0.7 mm). Specifically, 0.1 g of the surface treatment agent was loaded into a molybdenum boat in a vacuum deposition apparatus, and the inside of the vacuum deposition apparatus was pressurized to a pressure of 3.0 × 10 －３ The chamber was evacuated to a pressure of 100 Pa or less. Subsequently, a silicon dioxide film containing Na was formed to a thickness of 5 nm by electron beam deposition using the molded body 1, and the boat was subsequently heated by resistance heating to form a surface treatment layer (i.e., a water-repellent layer). Subsequently, a heat treatment was performed in an oven at 150°C for 2 hours, thereby obtaining a surface treatment layer.

[0666] <Evaluation> [Measurement of water contact angle after film formation] The surface of the substrate with the surface treatment layer prepared by the above method was thoroughly wiped with Kimwipe S-200 (product name, manufactured by Nippon Paper Crecia) soaked in ethanol, and then the static contact angle of water was measured.

[0667] (Contact Angle Measurement) The contact angle was measured using a fully automatic contact angle meter DropMaster 700 (manufactured by Kyowa Interface Science Co., Ltd.) in an environment of 25°C. Specifically, the substrate having the surface treatment layer to be measured was placed horizontally, 2 μL of water was dropped onto the surface from a microsyringe, and a still image was taken with a video microscope 1 second after the drop to measure the static contact angle. The static contact angle was measured at five different points on the surface treatment layer of the substrate, and the average value was calculated.
