[0451] In one embodiment, the surface treatment agent (coating liquid) of the present disclosure is for a dry coating method, preferably for vacuum deposition.

[0452] In one embodiment, the surface treatment agent (coating liquid) of the present disclosure is for wet coating, preferably immersion coating.

[0453] The surface treatment agent (coating liquid) disclosed herein can be formed into pellets by impregnating porous materials, such as porous ceramic materials, metal fibers, such as steel wool compressed into a cotton-like form. These pellets can be used, for example, in vacuum deposition.

[0454] The compositions of this disclosure are preferably used as surface treatment agents or as components of surface treatment agents.

[0455] The articles of this disclosure are described below.

[0456] The articles of this disclosure include a substrate and a layer (surface treatment layer) formed on the surface of the substrate from a surface treatment agent (coating liquid) of this disclosure.

[0457] The substrates usable in this disclosure may consist of, for example, glass, resin (natural or synthetic resin, such as common plastic materials), metal, ceramics, semiconductors (silicon, germanium, etc.), fibers (textiles, nonwovens, etc.), fur, leather, wood, ceramics, stone, building materials, sanitary products, or any other suitable material.

[0458] For example, if the article to be manufactured is an optical component, the material constituting the surface of the substrate may be an optical component material, such as glass or transparent plastic. Also, if the article to be manufactured is an optical component, some layer (or film), such as a hard coat layer or an anti-reflective layer, may be formed on the surface (outermost layer) of the substrate. Either a single-layer anti-reflective layer or a multi-layer anti-reflective layer may be used for the anti-reflective layer. Examples of inorganic materials that can be used for the anti-reflective layer include SiO2, SiO, ZrO2, TiO2, TiO, Ti2O3, Ti2O5, Al2O3, Ta2O5, Ta3O5, Nb2O5, HfO2, Si3N4, CeO2, MgO, Y2O3, SnO2, MgF2, and WO3. These inorganic materials may be used individually or in combination of two or more (for example, as a mixture). When a multi-layer anti-reflective layer is used, it is preferable to use SiO2 and / or SiO for the outermost layer. If the article to be manufactured is an optical glass component for a touch panel, a thin film using a transparent electrode, such as indium tin oxide (ITO) or indium zinc oxide, may be present on a portion of the surface of the substrate (glass). Furthermore, depending on its specific specifications, 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, and a liquid crystal display module.

[0459] The shape of the substrate is not particularly limited and may be, for example, a plate, a film, or other form. Furthermore, the surface area of ​​the substrate on which the surface treatment layer is to be formed may be at least a part of the substrate surface and can be appropriately determined according to the intended use and specific specifications of the article to be manufactured.

[0460] In one embodiment, the substrate may consist of a material that originally has hydroxyl groups, at least on its surface. Examples of such materials include glass, metals (especially base metals) on which a native oxide film or thermal oxide film is formed on the surface, ceramics, semiconductors, etc. Alternatively, if the material has insufficient hydroxyl groups, such as resins, or if it does not originally have hydroxyl groups, the substrate can be pretreated to introduce or increase hydroxyl groups on its surface. Examples of such pretreatment 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 formed in the form of a monolayer on the substrate surface by the LB method (Langmuir-Bludget method) or chemical adsorption method, and then the unsaturated bonds are cleaved in an atmosphere containing oxygen or nitrogen.

[0461] In another embodiment, such a substrate may consist of a material in which at least its surface portion is made of another reactive group, such as a silicone compound having one or more Si-H groups, or an alkoxysilane.

[0462] In a preferred embodiment, the substrate is glass. Preferred glass includes 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.

[0463] 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, the adhesion between the glass and the surface treatment layer is improved, and the durability is improved.

[0464] In a preferred embodiment, the intermediate layer may contain an alkali metal in addition to silicon oxide.

[0465] Examples of the alkali metals mentioned above include lithium, sodium, and potassium. The alkali metal is preferably sodium.

[0466] 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 setting the thickness of the intermediate layer to be above the lower limit of the above range, the effect of improving adhesion by the intermediate layer becomes greater.

[0467] The alkali metal atom concentration in the intermediate layer can be measured using various surface analysis devices, such as TOF-SIMS, XPS, and XRF.

[0468] The proportion of alkali metal atoms in the total atoms of the intermediate layer can be obtained by XPS depth profiling using ion sputtering. This is done by repeatedly alternating between XPS measurement and surface etching using an ion gun built into the XPS instrument.

[0469] In the intermediate layer, the average concentration of alkali metals in the region with a depth of 1 nm or less from the surface in contact with the surface treatment layer is determined by obtaining a depth profile of alkali metal atom concentrations using TOF-SIMS (time-of-flight secondary ion mass spectrometry) depth profiling by ion sputtering, and then calculating the average value of alkali metal atom concentrations in that profile. TOF-SIMS depth profiling by ion sputtering is performed by repeatedly alternating between TOF-SIMS measurement and surface etching using an ion gun built into the TOF-SIMS instrument.

[0470] The articles of this disclosure can be manufactured by forming a layer of the surface treatment agent of this disclosure on the surface of the substrate, and post-treating this layer as necessary, thereby forming a layer from the surface treatment agent of this disclosure.

[0471] Layer formation of the surface treatment agent of this disclosure can be carried out by applying the surface treatment agent to the surface of a substrate so as to cover the surface. The coating method is not particularly limited. For example, wet coating and dry coating methods can be used.

[0472] Examples of wet coating methods include immersion coating, spin coating, flow coating, spray coating, roll coating, gravure coating, wipe coating, squeegee coating, die coating, inkjet, cast coating, Langmuir-Bludget method, and similar methods.

[0473] Examples of dry coating methods include vapor deposition (usually vacuum deposition), sputtering, CVD, and similar methods. Specific examples of vapor deposition methods (usually vacuum deposition) include resistance heating, electron beams, high-frequency heating using microwaves, ion beams, and similar methods. Specific examples of CVD methods include plasma-CVD, optical CVD, thermal CVD, and similar methods.

[0474] Furthermore, coating using the atmospheric pressure plasma method is also possible.

Examples of substituents include hydroxyl groups, -OR 91 (Here, R 91 is C 1-10 Alkyl alkyl group, preferably C 1-3 Examples include alkyl groups (for example, a methyl group).

[0477] When using the dry coating method, the surface treatment agent of this disclosure may be subjected to the dry coating method as is, or it may be diluted with the solvent described above before being subjected to the dry coating method.

[0478] The layer formation of the surface treatment agent is preferably carried out such that the surface treatment agent of the present disclosure is present in the layer together with a catalyst for hydrolysis and dehydration condensation. For convenience, in the case of a wet coating method, the surface treatment agent of the present disclosure may be diluted with a solvent, and the catalyst may be added to the diluted solution of the surface treatment agent of the present disclosure immediately before application to the substrate surface. In the case of a dry coating method, the surface treatment agent of the present disclosure with the catalyst added may be directly vapor-deposited (usually by vacuum deposition), or a pellet-like material in which the surface treatment agent of the present disclosure with a catalyst (C) added as needed may be impregnated into a porous metal such as iron or copper may be vapor-deposited (usually by vacuum deposition).

[0479] The surface treatment layer included in the articles of this disclosure may have high abrasion resistance. In addition to high abrasion resistance, the surface treatment layer may also have water repellency, oil repellency, stain resistance (e.g., preventing the adhesion of dirt such as fingerprints), water resistance (preventing water from entering electronic components, etc.), surface slipperiness (or lubricity, e.g., ease of wiping away dirt such as fingerprints and excellent tactile feel to the fingers), and chemical resistance, and may be suitably used as a functional thin film.

[0480] Accordingly, this disclosure also relates to optical materials having the above-mentioned surface treatment layer as the outermost layer.

[0481] As optical materials, a wide variety of optical materials are preferred, in addition to optical materials related to displays, as exemplified below: for example, displays such as cathode ray tubes (CRTs; e.g., PC monitors), liquid crystal displays, plasma displays, organic EL displays, inorganic thin-film EL dot matrix displays, rear projection displays, fluorescent display tubes (VFDs), field emission displays (FEDs), or protective plates for such displays, or materials on which an anti-reflective coating has been applied to their surface.

[0482] The articles of this disclosure may be optical components, but are not limited to these. Examples of optical components include: lenses such as those in eyeglasses; front protective plates, anti-reflective 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 for optical discs such as Blu-ray (registered trademark) discs, DVD discs, CD-Rs, and MOs; optical fibers; and display surfaces for watches.

[0483] Furthermore, the articles of this disclosure may be medical devices or medical materials. Also, articles having layers obtained by this disclosure may be automotive interior and exterior components. 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.

[0484] The thickness of the above layer is not particularly limited. In the case of optical components, the thickness of the above layer may be in the range of, for example, 1 to 50 nm, preferably 1 to 30 nm, and more preferably 1 to 15 nm, from the viewpoint of optical performance, wear resistance, and antifouling properties.

[0485] For X-ray photoelectron spectroscopy (XPS) analysis to measure the atomic composition and constituent atom ratios of the surface treatment layer, the ULVAC-PHI PHI5000VersaProbeII can be used. XPS analysis conditions include a 25W monochromatic AlKα X-ray source, a 1400μm × 300μm photoelectron detection area, a photoelectron detection angle in the range of 20 to 90 degrees (e.g., 20, 45, 90 degrees), and a pass energy of 23.5eV. For sputtering, gas cluster ion beams or Ar ions can be used. Using the above apparatus 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 the intermediate layer.

[0486] Furthermore, depth analysis can also be performed. For XPS analysis, the measurement conditions include using a monochromatic AlKα X-ray source at 25W, a photoelectron detection area of ​​1400 μm × 300 μm, a photoelectron detection angle in the range of 20 to 90 degrees (e.g., 20 degrees, 45 degrees, 90 degrees), and a pass energy of 23.5 eV. Sputter ions such as Ar ions, gas cluster ions, and C60 ions can be used. Sputtering can also be used to etch 1 to 100 nm and obtain the composition of the coating film at each etching depth.

[0487] By adjusting the photoelectron detection angle in the XPS analysis described above, the detection depth can be adjusted as needed. For example, by setting a shallow angle close to 20 degrees, the detection depth can be set to about 3 nm, while by setting a deep angle close to 90 degrees, the detection depth can be set to about 10-something nm.

[0488] The silicon dioxide intermediate layer described above can be formed by applying a silicon dioxide precursor to the surface of the substrate. If the intermediate layer contains an alkali metal, it can be formed by applying a composition containing a silicon dioxide precursor and an alkali metal source to the surface of the substrate.

[0489] Examples of silicon oxide precursors include silicic acid, partial condensates of silicic acid, alkali metal silicates, silane compounds having a hydrolyzable group bonded to a silicon atom, and partial hydrolyzable condensates of the silane compounds. Silicic acid and its partial condensates can be dehydrated and condensed to produce silicon oxide, while alkali metal silicates can be converted to silicic acid or its partial condensates using an acid or cation exchange resin, and the resulting silicic acid or partial condensates can be dehydrated and condensed to produce silicon oxide. Examples of hydrolyzable groups in silane compounds having a hydrolyzable group bonded to a silicon atom include alkoxy groups and chlorine atoms. The hydrolyzable group in the silane compound can be hydrolyzed to a hydroxyl group, and the resulting silanol compound can be dehydrated and condensed to produce silicon oxide. Examples of silane compounds having a hydrolyzable group bonded to a silicon atom include alkoxysilanes such as tetraalkoxysilanes and alkyltrialkoxysilanes, and tetrachlorosilanes.

[0490] Examples of alkali metal sources include alkali metal hydroxides and water-soluble alkali metal salts. Examples of water-soluble alkali metal salts include alkali metal carbonates, alkali metal bicarbonates, alkali metal hydrochlorides, and alkali metal nitrates. As alkali metal sources, alkali metal hydroxides and alkali metal carbonates are preferred, alkali metal hydroxides are more preferred, and Na is even more preferred.

[0491] Furthermore, 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 silicon oxide produced during this process. Therefore, by adjusting the amount of residual alkali metal, silicon oxide containing a predetermined amount of alkali metal atoms can be obtained.

[0492] The thickness of the above-mentioned 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.

[0493] The compounds, compositions, and articles of this disclosure have been described in detail above. However, the compounds, compositions, and articles of this disclosure are not limited to those exemplified above. [Examples]
