[0175] When used in this specification, "monovalent organic group" refers to a monovalent group containing carbon. The monovalent organic group is not particularly limited and may be a hydrocarbon group or a derivative thereof. A derivative of a hydrocarbon group refers to a group having one or more N, O, S, Si, amide, sulfonyl, siloxane, carbonyl, carbonyloxy, etc. at the end of the hydrocarbon group or in the molecular chain. Among them, when simply written as "organic group", it means a monovalent organic group. In addition, a "divalent organic group" refers to a divalent group containing carbon. As such a divalent organic group, for example, a divalent group in which one hydrogen atom is further removed from the organic group can be cited. The same is true for trivalent or higher organic groups, which means a group in which a specified number of hydrogen atoms are removed from the organic group.

[0176] As used in this specification, "hydrocarbon group" is a group containing carbon and hydrogen, and refers to a group obtained by removing hydrogen atoms from hydrocarbon. Such a hydrocarbon group is not particularly limited, and examples thereof include C 1－20 Hydrocarbon groups, such as aliphatic hydrocarbon groups, aromatic hydrocarbon groups, etc. The above-mentioned "aliphatic hydrocarbon groups" can be any of linear, branched or cyclic, and can also be any of saturated or unsaturated. In addition, the hydrocarbon group can also contain one or more ring structures. The hydrocarbon group can also be substituted by one or more substituents.

[0177] As used in this specification, the substituent of the "hydrocarbon group" is not particularly limited, and examples thereof include halogen atoms, C 1－6 Alkyl, C 2－6 Alkenyl, C 2－6 Alkynyl, C 3－10 Cycloalkyl, C 3－10 unsaturated cycloalkyl, 5- to 10-membered heterocyclic group, 5- to 10-membered unsaturated heterocyclic group, C 6﹣10 One or more of aryl and 5- to 10-membered heteroaryl.

[0178] As used in this specification, "hydrolyzable group" refers to a group that can undergo a hydrolysis reaction, that is, a group that can be separated 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 , -NCO, halogen (in these formulas, R h represents a substituted or unsubstituted alkyl group having 1 to 4 carbon atoms), etc., preferably -OR h (i.e. alkoxy). hExamples include unsubstituted alkyl groups such as methyl, ethyl, n-propyl, isopropyl, n-butyl, and isobutyl; and substituted alkyl groups such as chloromethyl. Among these, alkyl groups are preferred, unsubstituted alkyl groups are particularly preferred, and methyl or ethyl groups are more preferred.

[0670] For example, when the article to be manufactured is an optical component, the material constituting the surface of the substrate can be a material for optical components, such as glass or transparent plastic. In addition, when the article to be manufactured is an optical component, a certain layer (or film), such as a hard coating or an anti-reflection layer, can also be formed on the surface (outermost layer) of the substrate. The anti-reflection layer can use any of a single-layer anti-reflection layer and a multi-layer anti-reflection layer. Examples of inorganic substances that can be used in the anti-reflection layer include SiO2, SiO, ZrO2, TiO2, TiO, Ti2O3, Ti2O5, Al2O3, Ta2O5, Ta3O5, Nb2O5, HfO2, Si3N4, CeO2, MgO, Y2O3, SnO2, MgF2, WO3, etc. These inorganic substances can be used alone, or two or more of them can be used in combination (for example, in the form of a mixture). When a multi-layer anti-reflection layer is formed, it is preferred to use SiO2 and / or SiO in its outermost layer. When the article to be manufactured is an optical glass component for a touch panel, a transparent electrode may be provided on a portion of the surface of the substrate (glass), such as a thin film obtained by using indium tin oxide (ITO) or indium zinc oxide. In addition, the substrate may also have an insulating layer, an adhesive layer, a protective layer, a decorative frame layer (I-CON), an atomized film layer, a hard coating layer, a polarizing film, a phase difference film, and a liquid crystal display module, depending on its specific specifications.

[0671] The shape of the above-mentioned substrate is not particularly limited, for example, can be plate-like, film, other forms. In addition, the surface area of ​​the substrate that will form the surface treatment layer as long as at least a portion of the substrate surface can be appropriately determined according to the purpose of the article to be manufactured and specific specifications etc.

[0672] In one embodiment, such a substrate may be a substrate whose surface is at least partially formed by a material that originally has hydroxyl groups. As such a material, glass may be cited, and metals (especially base metals), ceramics, semiconductors, etc. that form a natural oxide film or a thermal oxide film on the surface may also be cited. Alternatively, as in the case of resins, even if there are insufficient hydroxyl groups, or in the case of not having hydroxyl groups originally, by subjecting the substrate to a certain pretreatment, hydroxyl groups can be introduced into the surface of the substrate or increased. As examples of such pretreatments, plasma treatment (such as corona discharge) or ion beam irradiation may be cited. In order to be able to introduce hydroxyl groups into the surface of the substrate or increase hydroxyl groups and to purify the surface of the substrate (remove foreign matter, etc.), plasma treatment may also be suitable. In addition, as other examples of such pretreatments, the following methods may be cited: using the LB method (Langmuir-Blodgett method) or chemical adsorption method, an interface adsorbent having a carbon-carbon unsaturated bond group is formed in advance in the form of a monomolecular film on the surface of the substrate, and then the unsaturated bonds are disconnected in an atmosphere containing oxygen, nitrogen, etc.

[0673] In another embodiment, such a substrate may be a substrate at least the surface of which is formed of an organic silicon compound having one or more other reactive groups, for example, a Si—H group, or a material containing an alkoxysilane.

[0674] In a preferred embodiment, the substrate is glass. As such glass, sapphire glass, soda-lime glass, alkali-aluminosilicate glass, borosilicate glass, alkali-free glass, crystal glass, and quartz glass are preferred, and chemically strengthened soda-lime glass, chemically strengthened alkali-aluminosilicate glass, and chemically bonded borosilicate glass are particularly preferred.

[0675] In one embodiment, the article of the present invention may have 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.

[0676] In a preferred embodiment, the intermediate layer may contain an alkali metal in addition to silicon oxide.

[0677] Examples of the alkali metal include lithium, sodium, potassium, etc. The alkali metal is preferably sodium.

[0678] The thickness of the intermediate layer is not particularly limited, but is preferably 1 to 200 nm, particularly preferably 1 to 20 nm. When the thickness of the intermediate layer is equal to or greater than the lower limit of the above range, the effect of improving the adhesiveness by the intermediate layer is greater.

[0679] The concentration of alkali metal atoms in the intermediate layer can be measured using various surface analysis devices, such as TOF-SIMS, XPS, and XRF.

[0680] The ratio of alkali metal atoms to all atoms in the entire intermediate layer can be obtained by XPS depth analysis using ion sputtering by alternately repeating measurement using XPS and surface etching using ion sputtering using an ion gun built into the XPS apparatus.

[0681] In the intermediate layer, the average value of the alkali metal concentration in the region with a depth of 1 nm or less from the surface in contact with the surface treatment layer is obtained by calculating the average value of the alkali metal atom concentration on the distribution curve obtained by depth direction analysis of the concentration of alkali metal atoms in the depth direction by TOF-SIMS (time-of-flight secondary ion mass spectrometry) using ion sputtering. The TOF-SIMS depth direction analysis using ion sputtering is performed by alternately repeating measurement using TOF-SIMS and surface etching using ion sputtering using an ion gun built into the TOF-SIMS device.

[0682] The article of the present invention can be produced by forming a layer of the surface treatment agent of the present invention on the surface of the substrate and, if necessary, post-treating the layer to form a layer of the surface treatment agent of the present invention.

[0683] The layer formation of the surface treatment agent of the present invention can be carried out by applying the surface treatment agent to the surface of the substrate in a manner of covering the surface. The covering method is not particularly limited. For example, a wet covering method and a dry covering method can be used.

[0684] Examples of the wet coating method include dip coating, spin coating, flow coating, spray coating, roll coating, gravure coating, wipe coating, squeegee coating, die coating, ink jetting, casting, Langmuir-Blodgett method, and the like.

[0685] Examples of dry coating methods include evaporation (usually vacuum evaporation), sputtering, CVD, and similar methods. Specific examples of evaporation methods (usually vacuum evaporation) 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.

[0686] Alternatively, coating may be performed using a normal pressure plasma method.

[0688] When the dry coating method is used, the surface treatment agent of the present invention may be directly used for the dry coating method or may be diluted with the above-mentioned solvent and then used for the dry coating method.

[0689] The layer formation of the surface treatment agent is preferably implemented in a manner that the surface treatment agent of the present invention and the catalyst for hydrolysis and dehydration condensation coexist in the layer. In short, in the case of utilizing the wet covering method, the catalyst can be added to the diluent of the surface treatment agent of the present invention after diluting the surface treatment agent of the present invention with a solvent and before being applied to the substrate surface. In the case of utilizing the dry covering method, the surface treatment agent of the present invention after adding the catalyst can be directly subjected to vapor deposition (usually vacuum deposition) treatment, or the surface treatment agent of the present invention after adding the catalyst can be impregnated in a metal porous body such as iron or copper to obtain a granular material, and the obtained granular material is used for vapor deposition (usually vacuum deposition) treatment.

[0690] The catalyst may be any appropriate acid or base, transition metal (e.g., Ti, Ni, Sn, Zr, Al, B, etc.), sulfur-containing compounds having non-shared electron pairs 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. As an acid catalyst, for example, acetic acid, formic acid, trifluoroacetic acid, hydrochloric acid, nitric acid, sulfuric acid, phosphoric acid, sulfonic acid, methanesulfonic acid, p-toluenesulfonic acid, etc. may be used. In addition, as a base catalyst, for example, organic amines such as ammonia, sodium hydroxide, potassium hydroxide, triethylamine, diethylamine, etc. may be used. The transition metal, aliphatic amine compound, and aromatic amine compound may be the same as those mentioned above.

[0691] The surface treatment layer included in the article of the present invention has both high wear durability and fingerprint wiping performance. In addition, in addition to having high wear durability, the surface treatment layer can also have water repellency, oil repellency, antifouling properties (for example, preventing the adhesion of stains such as fingerprints), water repellency (preventing water from penetrating into electronic components, etc.), surface sliding properties (or lubricity, such as wiping performance of stains such as fingerprints, excellent finger touch), chemical resistance, etc., although it also varies depending on the composition of the surface treatment agent used, and is suitable for use as a functional film.

[0692] Therefore, the present invention also relates to an optical material having the above-mentioned surface treatment layer as the outermost layer.

[0693] As optical materials, in addition to optical materials related to displays such as those exemplified below, a variety of optical materials are preferably listed, for example: cathode ray tubes (CRT, such as computer monitors), liquid crystal displays, plasma displays, organic EL displays, inorganic thin film EL dot matrix displays, rear projection displays, fluorescent display tubes (VFD), field emission displays (FED, Field Emission Display) and other displays or protective plates of these displays, or materials with anti-reflection film treatment applied to their surfaces.

[0694] The article of the present invention is not particularly limited and may be an optical component. Examples of optical components include: lenses of glasses, etc.; front protection plates, anti-reflection plates, polarizing plates, anti-glare plates of displays such as PDP and LCD; touch panel sheets of devices such as mobile phones and portable information terminals; disc surfaces of Blu-ray (registered trademark) discs, DVD discs, CD-R, MO, etc.; optical fibers; display surfaces of clocks, etc.

[0695] In addition, the article of the present invention may also be a medical device or a medical material. In addition, the article having the layer obtained by the present invention may also be an interior and exterior material of an automobile. Examples of exterior materials include windows, lampshades, and exterior camera covers. Examples of interior materials include instrument panel covers, navigation system touch panels, and decorative interior materials.

[0696] The thickness of the layer is not particularly limited. In the case of an optical component, the thickness of the layer is preferably in the range of 1 to 50 nm, 1 to 30 nm, and preferably 1 to 15 nm from the viewpoint of optical performance, wear durability, and antifouling properties.

[0697] As an apparatus for X-ray photoelectron spectroscopy for measuring the atomic composition and atomic ratio of the surface treatment layer, XPS and PHI5000VersaProbeII manufactured by ULVAC-PHI can be used. As the measurement conditions of XPS analysis, the X-ray source can be set to 25W for monochromatized AlKα rays, the photoelectron detection area can be set to 1400μm×300μm, the photoelectron detection angle can be set to a range of 20 to 90 degrees (for example, 20 degrees, 45 degrees, 90 degrees), and the energy can be set to 23.5eV, etc., and sputtering can use gas cluster ion beams, Ar ions, etc. The peak areas of C1s, O1s, and Si2p are observed by the above-mentioned apparatus and measurement conditions, and the atomic ratios of carbon, oxygen, and silicon are calculated, thereby being able to determine the composition of the surface treatment layer and the intermediate layer.

[0698] In addition, it is also possible to perform analysis in the depth direction. As the measurement conditions for XPS analysis, the X-ray source can use monochromatic AlKα rays at 25W, the photoelectron detection area is set to 1400μm×300μm, the photoelectron detection angle is set to a range of 20 degrees to 90 degrees (for example, 20 degrees, 45 degrees, 90 degrees), the pass can be set to 23.5eV, etc., and the sputtering ions use Ar ions, gas cluster ions, C60 ions, etc. By sputtering 1 to 100nm etching, the composition of the coating at each depth after etching can also be obtained.

[0699] By adjusting the photoelectron detection angle of the XPS analysis, the detection depth can be appropriately adjusted. For example, by setting a shallow angle close to 20 degrees, the detection depth can be about 3 nm, and by setting a deep angle close to 90 degrees, the detection depth can be about tens of nm.

[0700] The silicon oxide-containing intermediate layer may 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 may be formed by applying a composition containing a silicon oxide precursor and an alkali metal source to the surface of the substrate.

[0701] As the above-mentioned silicon oxide precursor, silicic acid, partial condensates of silicic acid, alkali metal silicates, silane compounds having hydrolyzable groups bonded to silicon atoms, and partial hydrolysis condensates of the silane compounds can be listed. Silicic acid or its partial condensates can be dehydrated and condensed to form silicon oxide; alkali metal silicates can form silicic acid or its partial condensates using acid or cation exchange resins, and the generated silicic acid or its partial condensates can be dehydrated and condensed to form silicon oxide. As the hydrolyzable groups in the silane compounds having hydrolyzable groups bonded to silicon atoms, alkoxy groups, chlorine atoms, etc. can be listed. The hydrolyzable groups of the silane compounds are hydrolyzed to form hydroxyl groups, and the generated silanol compounds are dehydrated and condensed to form silicon oxide. As the silane compounds having hydrolyzable groups bonded to silicon atoms, alkoxysilanes such as tetraalkoxysilane and alkyltrialkoxysilane or tetrachlorosilane can be listed.

[0702] As the above-mentioned alkali metal source, alkali metal hydroxides, water-soluble alkali metal salts, etc. can be cited. As the water-soluble alkali metal salts, alkali metal carbonates, alkali metal hydrogen carbonates, alkali metal hydrochlorides, alkali metal nitrates, etc. As the alkali metal source, alkali metal hydroxides and alkali metal carbonates are preferred.

[0703] Among them, alkali metal silicates can be used as silicon oxide precursors and alkali metal sources. Although alkali metal silicates can form silicon oxide through silicic acid, a small amount of alkali metal will remain in the generated silicon oxide. Therefore, by adjusting the amount of residual alkali metal, silicon oxide containing a specified amount of alkali metal atoms can be obtained.

[0704] The thickness of the intermediate layer is not particularly limited, and 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.

[0705] The compounds, compositions, and articles of the present invention have been described in detail above, but the compounds, compositions, and articles of the present invention are not limited to the examples described above.
