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 Si ３ 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 ２It 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. 【0276】 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. 【0277】 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. 【0278】 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. 【0279】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. 【0280】 In one embodiment, the article of the present disclosure may include an intermediate layer containing silicon oxide between the substrate and the surface treatment layer. By providing such an intermediate layer, the adhesion between the substrate (e.g., glass) and the surface treatment layer is improved, and the durability is enhanced. 【0281】 In a preferred embodiment, the intermediate layer may contain an alkali metal in addition to silicon oxide. 【0282】 Examples of the alkali metals mentioned above include lithium, sodium, and potassium. Preferably, at least a portion of the alkali metal is sodium. 【0283】 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 is further enhanced. 【0284】 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 alkali metal atoms, it can be formed by applying a composition containing a silicon dioxide precursor and an alkali metal source to the surface of the substrate. 【0285】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. 【0286】 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. Alkali metal hydroxides and alkali metal carbonates are preferred as alkali metal sources. 【0287】 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 atoms, silicon oxide containing a predetermined amount of alkali metal atoms can be obtained. 【0288】 The alkali metal atom concentration in the intermediate layer can be measured using various surface analysis devices, such as TOF-SIMS, XPS, and XRF. 【0289】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. 【0290】 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. 【0291】 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. 【0292】 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. 【0293】 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. 【0294】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. 【0295】 Furthermore, coating using the atmospheric pressure plasma method is also possible. 【0296】When using a wet coating method, the surface treatment agents of the present disclosure may be diluted with a solvent before being applied to the substrate surface.
