[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 obtained by eliminating one additional hydrogen atom from an organic group. Similarly, a trivalent or higher organic group refers to a group obtained by eliminating a predetermined number of hydrogen atoms from an organic group.

[0008] As used herein, the term "hydrocarbon group" refers to a group containing carbon and hydrogen, which is 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 groups, 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 , -ON=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.

[0370] The Hansen solubility parameter (HSP) is a collective term for three parameters, δD, δP, and δH, which are indicators of the solubility of a substance. It is generally believed that various interactions, such as London dispersion force, hydrogen bonding force, dipole-dipole interaction, coordinate bond force, and inductive effect, are at work between a solute and a solvent. The HSP is an indicator proposed based on the theory that the three main interacting forces among these interactions are London dispersion force (δD), dipole-dipole force (δP), and hydrogen bonding force (δH), all of which are defined as values ​​greater than or equal to 0. In this disclosure, known values ​​were used as the Hansen solubility parameters of each substance.

[0371] The Hansen solubility parameter can be calculated and determined by known methods, such as those described in the June 2010 issue of Kagaku Kogyo (Kagaku Kogyosha) and Charles M. Hansen, Hansen Solubility Parameters: A Users Handbook (CRC Press, 2007). The Hansen solubility parameter of each substance can also be calculated based on an estimation method using a neural network method called Y-MB in computer software (HSPiP 5th Edition (ver. 5.4.08)). Furthermore, for substances for which literature values ​​are not known, the Hansen solubility parameter can also be calculated using the dissolving sphere method described below.

[0372] The dissolution sphere method is a method for calculating the Hansen solubility parameter of a target substance. The Hansen solubility parameter is determined by a solubility test in which the target substance is dissolved, dispersed, or miscible (hereinafter referred to as "dissolution") in a number of different solvents for which the Hansen solubility parameter has been established, and the solubility, dispersibility, or miscibility (hereinafter referred to as "solubility") of the target substance in a specific solvent is evaluated. The types of solvents used in the solubility test are preferably selected so that the values ​​of the dispersion term, polarity term, and hydrogen bonding term of the HSP of each solvent vary widely among the solvents. More specifically, evaluation is preferably performed using five or more, more preferably ten or more, even more preferably fifteen or more, and even more preferably seventeen or more solvents. Specifically, the Hansen solubility parameters for the solvents used in the solubility test are plotted on a three-dimensional coordinate system. Among the spheres with the largest radius (solubility sphere), all points of the solvents that dissolved the target substance are located inside the sphere, while all points of the solvents that did not dissolve the target substance are located outside the sphere. The coordinates of the center of this sphere are used as the Hansen solubility parameter of the target substance. The evaluation of solubility, etc. is carried out by visually determining whether or not the target substance has dissolved in the solvent. If the mixture of the target substance and the solvent becomes cloudy, the target substance precipitates, or the target substance and the solvent separate into layers, it can be determined that the target substance is not soluble in the solvent.

[0373] The Hansen solubility parameter is estimated from the latent heat of vaporization as shown in the following formula.

When multiple types of solvents are used, the total amount should be within the above range.

[0384] The composition of the present disclosure can be used as a surface treatment agent.

[0385] [Laminate] The laminate of the present disclosure includes a substrate and a water-repellent layer located on the substrate, The nitrogen concentration on the surface of the water-repellent layer is 0.01 atomic % or more and 1.3 atomic % or less.

[0386] [Base material] 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.

[0387] For example, if 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. Furthermore, if the article to be manufactured is an optical component, some layer (or film), such as a hard coat layer or an antireflection layer, may be formed on the surface (outermost layer) of the substrate. The antireflection layer may be either a single-layer antireflection layer or a multilayer antireflection layer. Examples of inorganic materials that can be used for the antireflection layer include SiO2, SiO, ZrO2, TiO2, TiO, Ti2O3, Ti2O5, Al2O3, Ta2O5, Ta3O5, Nb2O5, HfO2, Si3N4, CeO2, MgO, YO3, SnO2, MgF2, and WO3. These inorganic materials may be used alone or in combination (e.g., as a mixture) of two or more of them. When a multilayer antireflection layer is used, it is preferable to use SiO2 and / or SiO for the outermost layer. When the product to be manufactured is an optical glass component for a touch panel, a transparent electrode, such as 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 atomizing film layer, a hard coating film layer, a polarizing film, a phase difference film, a liquid crystal display module, etc., depending on the specific specifications.

[0388] 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 surface treatment 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 product to be manufactured.

[0389] 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, for materials such as resins, which do not have sufficient hydroxyl groups or do not originally contain hydroxyl groups, some pretreatment can be performed on the substrate to introduce or increase the number of hydroxyl groups on the 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 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 first formed in the form of a monomolecular film on the substrate surface by the Langmuir-Blodgett method (LB method) or chemical adsorption, followed by cleavage of the unsaturated bonds in an atmosphere containing oxygen, nitrogen, or the like.

[0390] In another embodiment, the substrate may have at least a surface portion made of a material containing another reactive group, such as a silicone compound having one or more Si—H groups, or an alkoxysilane.

[0391] In a preferred embodiment, the substrate is glass, such as sapphire glass, soda-lime glass, alkali aluminosilicate glass, borosilicate glass, alkali-free glass, crystal glass, quartz glass, and crystallized glass, with chemically strengthened soda-lime glass, chemically strengthened alkali aluminosilicate glass, and chemically bonded borosilicate glass being particularly preferred.

[0393] [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.

[0394] The water-repellent layer included in the laminate of the present disclosure has a nitrogen concentration on its surface of 0.01 atomic % or more and 1.3 atomic % or less.

[0395] The nitrogen concentration on the surface of the water-repellent layer is preferably 1.3 atomic % or less, more preferably 1.0 atomic % or less, and even more preferably 0.8 atomic % or less.

[0396] In a preferred embodiment, the nitrogen concentration on the surface of the water-repellent layer is 0.01 atomic % or more and 1.0 atomic % or less.

[0397] In one embodiment, the nitrogen concentration at the surface of the water-repellent layer included in the laminate of the present disclosure is lower than the nitrogen concentration of the entire water-repellent layer.

[0398] The nitrogen concentration in the entire water-repellent layer is the ratio of the number of nitrogen atoms to the total number of atoms in the compound represented by formula (1), expressed as a percentage (unit: atomic %). Therefore, "the nitrogen concentration at the surface is lower than the nitrogen concentration in the entire water-repellent layer" can refer to a state in which, for example, the compound of formula (1) contained in the water-repellent layer is oriented, causing the nitrogen-containing portion of the compound to be unevenly distributed inside the water-repellent layer rather than on the surface of the water-repellent layer.

[0399] In one embodiment, the fluorine concentration at the surface of the water-repellent layer included in the laminate of the present disclosure is preferably less than 5 atomic %, more preferably less than 1 atomic %, and even more preferably less than 0.1 atomic %.

[0400] In one embodiment, the water-repellent layer included in the laminate of the present disclosure includes a compound having a polydimethylsiloxane (PDMS) structure.

[0401] The type of the compound having the PDMS structure is not particularly limited, but it is preferably a silane compound exemplified by the formula (1) above.

[0402] In one embodiment, the PDMS concentration on the surface of the water-repellent layer included in the laminate of the present disclosure is 16.3% or more.

[0403] The PDMS concentration is not particularly limited as long as it is 16.3% or more, but is preferably 25.0% or more, more preferably 30.0% or more, and even more preferably 40.0% or more.

[0404] The concentrations of each element and PDMS on the surface of the water-repellent layer can be determined by surface analysis. Examples of surface analysis methods that can be used include X-ray photoelectron spectroscopy (XPS) and time-of-flight secondary ion mass spectrometry. Typically, XPS analysis is used.

[0405] The XPS analysis equipment used to measure the elemental concentrations on the water-repellent layer surface can be an ULVAC-PHI PHI5000 VersaProbe II. The XPS analysis conditions are a monochromated AlKα X-ray source at 25 W, a photoelectron detection area of ​​1400 μm × 300 μm, a photoelectron detection angle ranging from 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 equipment and measurement conditions, the concentrations of nitrogen, oxygen, carbon, fluorine, and silicon on the water-repellent layer surface can be determined based on the spectra of the N1s, O1s, C1s, F1s, and Si2p orbitals.

[0406] The detection depth can be adjusted appropriately by adjusting the photoelectron detection angle in the above XPS analysis. For example, a shallow angle of approximately 20 degrees can achieve a detection depth of approximately 3 nm, while a deep angle of approximately 90 degrees can achieve a detection depth of approximately 10 nm.

[0407] 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 result to calculate the silicon concentration on the surface of the water-repellent layer.

[0408] In the present disclosure, the "polydimethylsiloxane (PDMS) concentration" is a value that can be calculated by P1 / (P1+P2), where P1 is the peak area of ​​Si atoms derived from the PDMS structure of the silane compound, and P2 is the peak area derived from other Si atoms, as determined by XPS analysis of the water-repellent layer surface.

[0474] 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. In the case of a dry coating method, the surface treatment agent to which the catalyst has been added may be directly vapor-deposited (usually vacuum vapor-deposited), or a pellet-shaped material impregnated with the surface treatment agent to which the catalyst has been added may be vapor-deposited (usually vacuum vapor-deposited) onto a porous metal such as iron or copper.

[0476] In one embodiment, the laminate of the present disclosure is produced by a method including the step of applying the composition of the present disclosure to a substrate by a wet coating method to form a water-repellent layer.

[0477] The articles of the present disclosure are described below.

[0478] The article of the present disclosure comprises: A laminate including a substrate and a water-repellent layer located on the substrate, a laminate in which the nitrogen concentration in the surface of the water-repellent layer is 0.01 atomic % or more and 1.3 atomic % or less; Includes:

[0479] The article of the present disclosure may include any of the aspects described above for the laminate. For example, the article of the present disclosure may include a laminate in which the nitrogen concentration on the surface of the water-repellent layer is 0.01 atomic % or more and 1.0 atomic % or less. Also, for example, the article of the present disclosure may include a laminate in which the nitrogen concentration on the surface of the water-repellent layer is 0.01 atomic % or more and 1.3 atomic % or less and the PDMS concentration is 16.3% or more. Also, for example, the article of the present disclosure may include a laminate in which the nitrogen concentration on the surface of the water-repellent layer is 0.01 atomic % or more and 1.0 atomic % or less and the PDMS concentration is 25.0% or more.

[0480] In one embodiment, the article of the present disclosure may include an intermediate layer containing silicon oxide between the glass and the surface treatment layer. By providing such an intermediate layer, adhesion between the glass and the surface treatment layer is improved, and durability is improved.

[0481] In a preferred embodiment, the intermediate layer may contain alkali metal atoms in addition to silicon oxide.

[0482] Examples of the alkali metal atom include lithium, sodium, potassium, etc. The alkali metal atom is preferably sodium.

[0483] 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.

[0484] The alkali metal atom concentration in the intermediate layer can be measured by various surface analysis devices, such as TOF-SIMS, XPS, and XRF.

[0485] 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 alternating between XPS measurement and surface etching by ion sputtering using an ion gun built into the XPS instrument.

[0486] The average alkali metal concentration in the intermediate layer in a region 1 nm or less deep from the surface in contact with the surface treatment 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.

[0487] 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.

[0488] The article of the present disclosure may also be a medical device or medical material. The article having a surface treatment 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.

[0489] 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.

[0490] 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.

[0491] 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.

[0492] 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.

[0493] The water-repellent layer included in the article of the present disclosure can have high abrasion resistance as described above. Furthermore, in addition to high abrasion resistance, the surface treatment 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.

[0494] Therefore, the present disclosure also relates to an optical material having the above-described surface treatment layer as the outermost layer.

[0495] Preferred examples of the optical material include optical materials related 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.

[0496] 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.

[0497] 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.

[0498] The thickness of the layer is not particularly limited. In the case of optical members, the thickness of the layer may be, for example, 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.

[0499] X-ray photoelectron spectroscopy (XPS) can be performed using an ULVAC-PHI PHI5000 VersaProbe II instrument to measure the atomic composition and atomic ratios of the surface treatment layer. 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 ranging from 20° to 90° (e.g., 20°, 45°, 90°), and a pass energy of 23.5 eV. Gas cluster ion beams or Ar ions can be used for sputtering. Using the above instrument and measurement conditions, the peak areas of C1s, O1s, and Si2p can be observed, and the atomic ratios of carbon, oxygen, and silicon can be calculated to determine the composition of the surface treatment layer and intermediate layer.

[0500] Depth analysis can also be performed. 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, and 90 degrees), and a pass energy of 23.5 eV. Ar ions, gas cluster ions, and C ions can be used as sputtering ions. Sputtering can be used to etch 1 to 100 nm, and the composition of the coating at each etching depth can be determined.

[0501] The detection depth can be adjusted appropriately by adjusting the photoelectron detection angle in the XPS analysis. For example, a shallow angle of approximately 20 degrees can achieve a detection depth of approximately 3 nm, while a deep angle of approximately 90 degrees can achieve a detection depth of approximately 10-odd nm.

[0502] 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.

[0503] 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.

[0504] 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.

[0505] 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.

[0506] 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.

[Spin ​​coating process] Surface treatment agents were prepared by combining solvents and compounds as shown in Table 1 below. The compound concentration was 1.5 wt%.

[0519] <Evaluation> [Contact angle measurement] The contact angle was measured in a 25°C environment using a fully automatic contact angle meter, DropMaster 700 (manufactured by Kyowa Interface Science Co., Ltd.). Specifically, the substrate having the surface treatment layer to be measured was placed horizontally, water was dropped onto the surface from a microsyringe, and a still image was taken with a video microscope one 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.
