These pellets can be used, for example, in vacuum deposition.

[0721] The compositions of this disclosure are preferably used as surface treatment agents or as components of surface treatment agents.

[0722] The articles of this disclosure are described below.

[0723] 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.

[0724] 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.

[0725] 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. An example of an inorganic material that can be used for the anti-reflective layer is SiO ２ 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 Si３ N ４ , CEO ２ , MgO, Y ２ O ３ , SnO ２ MgF ２ WO ３ These are some examples. These inorganic materials may be used individually or in combination of two or more (for example, as a mixture). When a multilayer anti-reflective layer is used, the outermost layer is SiO ２ It is preferable to use and / or SiO. 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 part of the surface of the substrate (glass). The substrate may also 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, depending on its specific specifications.

[0726] 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.

[0727] 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.

[0728] 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.

[0729] 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.

By providing such an intermediate layer, the adhesion between the glass and the surface treatment layer is improved, and the durability is improved.

[0731] In a preferred embodiment, the intermediate layer may contain an alkali metal in addition to silicon oxide.

[0732] Examples of the alkali metal include lithium, sodium, potassium, etc. The alkali metal is preferably sodium.

[0733] 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 not less than the lower limit value of the above range, the effect of improving the adhesion by the intermediate layer becomes greater.

[0734] The concentration of alkali metal atoms in the intermediate layer can be measured by various surface analyzers, such as TOF-SIMS, XPS, XRF, etc.

[0735] The ratio of alkali metal atoms to all atoms in the entire intermediate layer can be obtained by XPS depth profile analysis by ion sputtering, and is performed by alternately repeating the measurement by XPS and the etching of the surface by ion sputtering using an ion gun built in the XPS apparatus.

[0736] In the intermediate layer, the average value of the concentration of alkali metal in the region where the depth from the surface in contact with the surface treatment layer is 1 nm or less is obtained by TOF-SIMS (time-of-flight secondary ion mass spectrometry) depth profile analysis by ion sputtering, and after obtaining the depth profile of the concentration of alkali metal atoms, the average value of the concentration of alkali metal atoms in the profile is calculated. The TOF-SIMS depth profile analysis by ion sputtering is performed by alternately repeating the measurement by TOF-SIMS and the etching of the surface by ion sputtering using an ion gun built in the TOF-SIMS apparatus.

[0737] The article of the present disclosure can be manufactured by forming the layer of the surface treatment agent of the present disclosure on the surface of the base material, post-treating this layer as necessary, and thereby forming a layer from the surface treatment agent of the present disclosure.

[0738] The formation of the layer of the surface treatment agent of the present disclosure can be carried out by applying the surface treatment agent to the surface of the base material so as to cover the surface. The coating method is not particularly limited. For example, wet coating method and dry coating method can be used.

[0739] 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, casting, Langmuir-Bludget method, and similar methods.

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 of optical discs such as Blu-ray (registered trademark) discs, DVD discs, CD-Rs, and MOs; optical fibers; and display surfaces of watches.

[0751] 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.

[0752] 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, abrasion resistance, and antifouling properties.

[0753] For X-ray photoelectron spectroscopy (XPS) analysis to measure the atomic composition and constituent atom ratios of the surface treatment layer, the PHI5000VersaProbeII from ULVAC-PHI can be used. XPS analysis conditions include a 25W monochromatic AlKα X-ray source, a 1400 μm × 300 μm 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 23.5 eV. 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.

[0754] 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. Ar ions, gas cluster ions, C60 ions, etc., can be used as sputtering ions. Etching from 1 to 100 nm by sputtering can also be performed to obtain the composition of the coating film at each etching depth.

[0755] 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.

[0756] The silicon dioxide-containing 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.

[0757] 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.

[0758] 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.

[0759] 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.

[0760] 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.

[0761] 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.
