In addition, when simply referring to an "organic group", it refers to a monovalent organic group. In addition, the term "divalent organic group" refers to a divalent group containing carbon. Examples of such divalent organic groups include divalent groups obtained by further removing one hydrogen atom from an organic group. Similarly, a trivalent or higher organic group refers to a group obtained by removing 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 a group obtained by removing a hydrogen atom from a hydrocarbon. Such a hydrocarbon group includes, but is not limited to, C 1-20Examples of the hydrocarbon group include an aliphatic hydrocarbon group and an aromatic hydrocarbon group. 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.

[0295] In one embodiment, the compositions of the present disclosure are for dry coating processes, preferably vacuum deposition.

[0296] In one embodiment, the compositions of the present disclosure are for use in wet coating methods, preferably dip coating.

[0297] The compositions of the present disclosure can be impregnated into porous materials, such as porous ceramic materials, metal fibers, such as steel wool, and formed into pellets, which can be used, for example, in vacuum deposition.

[0298] The composition of the present disclosure is preferably used as a surface treatment agent or as a component of a surface treatment agent.

[0299] The articles of the present disclosure are described below.

[0300] The article of the present disclosure includes a substrate and a layer (surface treatment layer) formed on the surface of the substrate from the surface treatment agent of the present disclosure.

[0301] Substrates that can be used in the present disclosure may be made of any suitable 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.

[0302] For example, when the article to be manufactured is an optical member, the material constituting the surface of the substrate may be a material for optical members, such as glass or transparent plastic. When the article to be manufactured is an optical member, the surface (outermost layer) of the substrate may have some layer (or film), such as a hard coat layer or an anti-reflection layer. The anti-reflection layer may be either a single-layer anti-reflection layer or a multi-layer anti-reflection layer. Examples of inorganic substances that can be used for the anti-reflection layer include SiO2, SiO, ZrO2, TiO2, TiO, Ti2O3, Ti2O5, Al2O3, Ta2O5, Ta3O5, Nb2O5, HfO2, Si3N4, CeO2, MgO, Y2O3, SnO2, MgF2, and WO3. These inorganic substances may be used alone or in combination of two or more of them (for example, as a mixture). When a multi-layer anti-reflection 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 part for a touch panel, a transparent electrode, for example, a thin film using indium tin oxide (ITO) or indium zinc oxide, may be provided on a part of the surface of the substrate (glass). In addition, 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.

[0303] 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 according to the application and specific specifications of the product to be manufactured.

[0304] In one embodiment, the substrate may be made of a material that originally has hydroxyl groups at least on its surface. Examples of such materials include glass, metals (particularly base metals), ceramics, semiconductors, etc., on whose surfaces natural oxide films or thermal oxide films are formed. Alternatively, in cases where the substrate has insufficient hydroxyl groups, such as resins, or where the substrate does not originally have hydroxyl groups, the substrate may be subjected to some pretreatment to introduce or increase the number of hydroxyl groups on the substrate 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 interface adsorbent having a carbon-carbon unsaturated bond group is formed in advance in the form of a monomolecular film on the substrate surface by the LB method (Langmuir-Blodgett method) or chemical adsorption method, etc., and then the unsaturated bond is cleaved in an atmosphere containing oxygen, nitrogen, etc.

[0305] In another embodiment, the substrate may be one in which at least the surface portion is made of a material containing another reactive group, such as a silicone compound having one or more Si-H groups, or an alkoxysilane.

[0306] In a preferred embodiment, the substrate is glass, preferably sapphire glass, soda-lime glass, alkali aluminosilicate glass, borosilicate glass, alkali-free glass, crystal glass, quartz glass, or crystallized glass, and more preferably chemically strengthened soda-lime glass, chemically strengthened alkali aluminosilicate glass, or chemically bonded borosilicate glass.

[0307] 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 durability is improved.

[0308] In a preferred embodiment, the intermediate layer may contain an alkali metal in addition to silicon oxide.

[0309] Examples of the alkali metal include lithium, sodium, potassium, etc. The alkali metal is preferably sodium.

[0310] 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 improving adhesiveness by the intermediate layer becomes greater.

[0311] 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 an alkali metal atom, 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.

[0312] 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 partial condensates thereof can be dehydrated and condensed to form silicon oxide, and alkali metal silicates can be converted to silicic acid and partial condensates thereof by using an acid or a cation exchange resin, and the resulting silicic acid and partial condensates can be dehydrated and condensed to form silicon oxide. Examples of the hydrolyzable group in the silane compound having a hydrolyzable group bonded to a silicon atom include an alkoxy group and a chlorine atom. The hydrolyzable group of the silane compound can be hydrolyzed to a hydroxyl group, and the resulting silanol compound can be dehydrated and condensed to form silicon oxide. Examples of the silane compound having a hydrolyzable group bonded to a silicon atom include alkoxysilanes such as tetraalkoxysilanes and alkyltrialkoxysilanes, and tetrachlorosilanes.

[0313] The alkali metal source includes alkali metal hydroxides, water-soluble alkali metal salts, etc. The water-soluble alkali metal salts include alkali metal carbonates, alkali metal hydrogencarbonates, alkali metal hydrochlorides, alkali metal nitrates, etc. The alkali metal source is preferably an alkali metal hydroxide or an alkali metal carbonate.

[0314] In addition, alkali metal silicate can be used as a silicon oxide precursor and an alkali metal source. The alkali metal silicate can be converted into silicon oxide via silicic acid, but a small amount of alkali metal may remain in the silicon oxide produced at that time. Therefore, the amount of the remaining alkali metal atoms can be adjusted to obtain silicon oxide containing a predetermined amount of alkali metal atoms.

[0315] The alkali metal atom concentration in the intermediate layer can be measured by various surface analysis devices, such as TOF-SIMS, XPS, and XRF.

[0316] The proportion of alkali metal atoms in the total atoms of the entire intermediate layer can be obtained by XPS depth profiling 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.

[0317] In the intermediate layer, the average value of the alkali metal concentration in a region 1 nm or less deep from the surface in contact with the surface treatment layer is obtained by obtaining a depth profile of the alkali metal atom concentration by TOF-SIMS (time-of-flight secondary ion mass spectrometry) depth profile analysis by ion sputtering, and then calculating the average value of the alkali metal atom concentration in the profile. The TOF-SIMS depth profile analysis by 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.

[0318] The article of the present disclosure can be produced by forming a layer of the surface treatment agent of the present disclosure on the surface of the substrate, and then post-treating this layer as necessary, thereby forming a layer from the surface treatment agent of the present disclosure.

[0319] The layer formation of the surface treatment agent of the present disclosure can be carried out by applying the surface treatment agent to the surface of the substrate so as to coat the surface. The coating method is not particularly limited. For example, a wet coating method and a dry coating method can be used.

[0320] Examples of wet coating methods include dip coating, spin coating, flow coating, spray coating, roll coating, gravure coating, wipe coating, squeegee coating, die coating, ink jet, casting, Langmuir-Blodgett coating, and the like.

[0321] Examples of dry coating methods include deposition (usually vacuum deposition), sputtering, CVD, and similar methods. Specific examples of deposition methods (usually vacuum deposition) include resistance heating, electron beam, high frequency heating such as with microwaves, ion beam, and similar methods. Specific examples of CVD methods include plasma-CVD, optical CVD, thermal CVD, and similar methods.

[0325] When the dry coating method is used, the surface treatment agent of the present disclosure may be subjected to the dry coating method as it is, or may be subjected to the dry coating method after being diluted with the above-mentioned solvent.

[0326] The layer formation of the surface treatment agent is preferably carried out so that the surface treatment agent of the present disclosure is present together with a catalyst for hydrolysis and dehydration condensation in the layer. Conveniently, in the case of the wet coating method, the surface treatment agent of the present disclosure may be diluted with a solvent, and then a 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 the dry coating method, the surface treatment agent of the present disclosure to which the catalyst has been added may be directly subjected to deposition (usually vacuum deposition) treatment, or a metal porous body such as iron or copper may be subjected to deposition (usually vacuum deposition) treatment using a pellet-shaped material impregnated with the surface treatment agent of the present disclosure to which the catalyst has been added.

[0327] The catalyst may be any suitable acid or base, transition metal (e.g., Ti, Ni, Sn, Zr, Al, B, etc.), sulfur-containing compound having an unshared electron pair in the molecular structure, or nitrogen-containing compound (e.g., sulfoxide compound, aliphatic amine compound, aromatic amine compound, phosphoric acid amide compound, amide compound, urea compound), etc. The acid catalyst may be, for example, acetic acid, formic acid, trifluoroacetic acid, hydrochloric acid, nitric acid, sulfuric acid, phosphoric acid, sulfonic acid, methanesulfonic acid, p-toluenesulfonic acid, etc. The base catalyst may be, for example, ammonia, sodium hydroxide, potassium hydroxide, organic amines such as triethylamine, diethylamine, etc. The transition metal, aliphatic amine compound, and aromatic amine compound may be the same as those described above.

[0328] The surface treatment layer included in the article of the present disclosure can have high abrasion resistance.In addition to high abrasion resistance, the surface treatment layer can have water repellency, oil repellency, antifouling properties (for example, preventing adhesion of dirt such as fingerprints), waterproof properties (preventing water from penetrating into electronic components, etc.), surface slipperiness (or lubricity, for example, wiping off dirt such as fingerprints, and excellent tactile sensation against fingers), chemical resistance, etc., depending on the composition of the surface treatment agent used, and can be suitably used as a functional thin film.

[0329] Therefore, the present disclosure further relates to an optical material having the above-mentioned surface treatment layer as the outermost layer.

[0330] Preferred examples of the optical material include optical materials relating 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 electroluminescence displays, inorganic thin-film electroluminescence dot matrix displays, rear projection displays, vacuum fluorescent displays (VFDs), field emission displays (FEDs), and other displays, protective plates for such displays, or displays whose surfaces have been treated with an anti-reflection film.

[0331] The article of the present disclosure may be, but is not limited to, an optical member. Examples of optical members include lenses for glasses, front protection 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 for optical discs such as Blu-ray (registered trademark) discs, DVD discs, CD-Rs, and MOs, optical fibers, and display surfaces for watches.

[0332] The article of the present disclosure may be a medical device or medical material. The article having a layer obtained by the present disclosure may be an automobile interior or exterior member. Examples of exterior materials include windows, light covers, and exterior camera covers. Examples of interior materials include instrument panel covers, navigation system touch panels, and decorative interior materials.

[0333] The thickness of the layer is not particularly limited. In the case of an optical member, 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.

[0334] As an apparatus for performing X-ray photoelectron spectroscopy to measure the atomic composition and the ratio of constituent atoms of the surface treatment layer, an XPS, PHI5000VersaProbeII manufactured by ULVAC-PHI, Inc. can be used. The measurement conditions for XPS analysis are a monochromatic AlKα ray of 25 W for the X-ray source, a photoelectron detection area of ​​1400 μm × 300 μm, a photoelectron detection angle in the range of 20 degrees to 90 degrees (for example, 20 degrees, 45 degrees, 90 degrees), a pass energy of 23.5 eV, etc., and gas cluster ion beams, Ar ions, etc. can be used for sputtering. With 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.

[0335] It is also possible to carry out analysis in the depth direction. The measurement conditions for XPS analysis are: monochromatic AlKα radiation at 25 W as the X-ray source; photoelectron detection area of ​​1400 μm×300 μm; photoelectron detection angle in the range of 20 degrees to 90 degrees (for example, 20 degrees, 45 degrees, 90 degrees); pass energy of 23.5 eV; and Ar ions, gas cluster ions, C60 ions, etc. can be used as sputter ions. It is also possible to etch 1 to 100 nm by sputtering, and obtain the composition in the coating film at each etching depth.

[0336] By adjusting the photoelectron detection angle in the above XPS analysis, the detection depth can be appropriately adjusted. For example, a shallow angle close to 20 degrees can provide a detection depth of about 3 nm, while a deep angle close to 90 degrees can provide a detection depth of about 10 nm.

[0337] 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.

[0338] 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 partial condensates thereof can be dehydrated and condensed to form silicon oxide, and alkali metal silicates can be converted to silicic acid and partial condensates thereof by using an acid or a cation exchange resin, and the resulting silicic acid and partial condensates can be dehydrated and condensed to form silicon oxide. Examples of the hydrolyzable group in the silane compound having a hydrolyzable group bonded to a silicon atom include an alkoxy group and a chlorine atom. The hydrolyzable group of the silane compound can be hydrolyzed to a hydroxyl group, and the resulting silanol compound can be dehydrated and condensed to form silicon oxide. Examples of the silane compound having a hydrolyzable group bonded to a silicon atom include alkoxysilanes such as tetraalkoxysilanes and alkyltrialkoxysilanes, and tetrachlorosilanes.

[0339] The alkali metal source includes alkali metal hydroxides, water-soluble alkali metal salts, etc. The water-soluble alkali metal salts include alkali metal carbonates, alkali metal hydrogencarbonates, alkali metal hydrochlorides, alkali metal nitrates, etc. The alkali metal source is preferably an alkali metal hydroxide or an alkali metal carbonate.

[0340] In addition, alkali metal silicate can be used as a silicon oxide precursor and an alkali metal source. The alkali metal silicate can be converted into silicon oxide via silicic acid, but a small amount of alkali metal may remain in the silicon oxide produced at that time. Therefore, the amount of the remaining alkali metal can be adjusted to obtain silicon oxide containing a predetermined amount of alkali metal atoms.

[0341] 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 further preferably 3 to 10 nm.

[0342] The silane compound of the present disclosure, the surface treatment agent containing the silane compound, the article obtained by using the surface treatment agent, etc. have been described in detail above. Note that the present disclosure is not limited to the above examples. EXAMPLES
