[0007] As used herein, the term "monovalent organic group" refers to a monovalent group containing carbon. The monovalent organic group is not particularly limited, but may be a hydrocarbon group or a derivative thereof. A hydrocarbon group derivative refers to a group having one or more N, O, S, Si, amide, sulfonyl, siloxane, carbonyl, carbonyloxy, etc. at the end or in the molecular chain of the hydrocarbon group. Note that when simply referring to an "organic group," it refers to a monovalent organic group. Furthermore, the term "divalent organic group" refers to a divalent group containing carbon. Examples of such divalent organic groups include divalent groups obtained by eliminating one additional hydrogen atom from an organic group. Similarly, a trivalent or higher organic group refers to a group obtained by eliminating 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 obtained by removing a hydrogen atom from a hydrocarbon. Such hydrocarbon groups include, but are not limited to, C 1-20 Examples of hydrocarbon groups include aliphatic hydrocarbon groups and aromatic hydrocarbon groups. 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. The hydrocarbon group may be substituted with one or more substituents.

[0009] As used herein, the substituent of the "hydrocarbon group" is not particularly limited, but examples thereof include a halogen atom, a C 1-6 Alkyl group, C 2-6 Alkenyl group, C 2-6 Alkynyl group, C 3-10 Cycloalkyl groups, C 3-10 Unsaturated cycloalkyl groups, 5- to 10-membered heterocyclyl groups, 5- to 10-membered unsaturated heterocyclyl groups, C 6-10 Examples include one or more groups selected from aryl groups and 5- to 10-membered heteroaryl groups.

[0010] As used herein, the term "hydrolyzable group" refers to a group that can undergo a hydrolysis reaction, i.e., a group that can be removed from the main skeleton of a compound by a hydrolysis reaction. Examples of hydrolyzable groups include -OR h , -OCOR h , -ON=CR h 2, -NR h 2, -NHR h , —NCO, or halogen (wherein R h represents a substituted or unsubstituted alkyl group having 1 to 4 carbon atoms), and preferably -OR h (i.e., an alkoxy group). h Examples of the alkyl group include unsubstituted alkyl groups such as methyl, ethyl, propyl, isopropyl, n-butyl, and isobutyl; and substituted alkyl groups such as chloromethyl.

[0278] In one embodiment, the surface treatment agent is for dry coating, preferably vacuum deposition.

[0279] In one embodiment, the surface treatment agent is for a wet coating method, preferably for dip coating.

[0280] The surface treatment agent can be impregnated into a porous material, such as a porous ceramic material or a metal fiber, such as a flocculated steel wool, to form pellets, which can be used for vacuum deposition, for example.

[0281] (Goods) The articles of the present disclosure are described below.

[0282] 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.

[0283] 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 common 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.

[0284] For example, if the article to be manufactured is an optical component, the material constituting the surface of the substrate may be a material for optical components, such as glass or transparent plastic. Furthermore, if the article to be manufactured is an optical component, some layer (or film), such as a hard coat layer or an antireflection layer, may be formed on the surface (outermost layer) of the substrate. The antireflection layer may be either a single-layer antireflection layer or a multilayer antireflection layer. Examples of inorganic materials that can be used for the antireflection layer include SiO2, SiO, ZrO2, TiO2, TiO, Ti2O3, Ti2O5, Al2O3, Ta2O5, Ta3O5, Nb2O5, HfO2, Si3N4, CeO2, MgO, YO3, SnO2, MgF2, and WO3. These inorganic materials may be used alone or in combination (e.g., as a mixture) of two or more of them. When a multilayer antireflection 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 component for a touch panel, a transparent electrode, such as a thin film using indium tin oxide (ITO) or indium zinc oxide, may be provided on a portion of the surface of the substrate (glass). Furthermore, 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.

[0285] 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 depending on the use and specific specifications of the product to be manufactured.

[0286] In one embodiment, at least the surface portion of such a substrate may be made of a material that originally contains hydroxyl groups. Examples of such materials include glass, metals (especially base metals), ceramics, semiconductors, and the like, on whose surfaces native oxide or thermal oxide films form. Alternatively, for materials such as resins, which do not have sufficient hydroxyl groups or do not originally contain hydroxyl groups, some pretreatment can be performed on the substrate to introduce or increase the number of hydroxyl groups on the surface. Examples of such pretreatments 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 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 first formed in the form of a monomolecular film on the substrate surface by the Langmuir-Blodgett method (LB method) or chemical adsorption, followed by cleavage of the unsaturated bonds in an atmosphere containing oxygen, nitrogen, or the like.

[0287] In another embodiment, the substrate may have at least a surface portion made of a material containing another reactive group, such as a silicone compound having one or more Si—H groups, or an alkoxysilane.

[0288] In a preferred embodiment, the substrate is glass, such as sapphire glass, soda-lime glass, alkali aluminosilicate glass, borosilicate glass, alkali-free glass, crystal glass, or quartz glass, with chemically strengthened soda-lime glass, chemically strengthened alkali aluminosilicate glass, and chemically bonded borosilicate glass being particularly preferred.

[0289] 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, adhesion between the glass and the surface treatment layer is improved, and durability is improved.

[0290] In a preferred embodiment, the intermediate layer may contain an alkali metal in addition to silicon oxide.

[0291] Examples of the alkali metal include lithium, sodium, potassium, etc. The alkali metal is preferably sodium.

[0292] 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 the intermediate layer in improving adhesiveness becomes greater.

[0293] The alkali metal atom concentration in the intermediate layer can be measured by various surface analysis devices, such as TOF-SIMS, XPS, and XRF.

[0294] The proportion of alkali metal atoms in the total atoms of the entire intermediate layer can be obtained by XPS depth profile analysis 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.

[0295] The average alkali metal concentration in the intermediate layer in a region 1 nm or less deep from the surface in contact with the surface treatment layer is determined by obtaining a depth profile of the alkali metal atom concentration by TOF-SIMS (time-of-flight secondary ion mass spectrometry) depth profile analysis using ion sputtering, and then calculating the average alkali metal atom concentration in the profile. TOF-SIMS depth profile analysis using 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.

[0296] 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.

[0297] 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 a substrate so as to coat the surface. The coating method is not particularly limited. For example, a wet coating method or a dry coating method can be used.

[0298] 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 similar methods.

[0299] 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 beam, high frequency heating using microwaves, ion beam, and similar methods. Specific examples of CVD methods include plasma-CVD, optical CVD, thermal CVD, and similar methods.

[0300] Furthermore, coating by atmospheric pressure plasma method is also possible.

[0301] When using the wet coating method, the surface treatment agent of the present disclosure can be diluted with a solvent and then applied to the substrate surface.

These solvents can be used alone or in combination. Among these, glycol ethers, alcohols, ether alcohols, and siloxanes are preferred. For example, propylene glycol monomethyl ether, propylene glycol monoethyl ether, propylene glycol monobutyl ether, methanol, ethanol, iso-propanol, n-butanol, isobutanol, tert-butanol, sec-butanol, diethylene glycol monomethyl ether, hexamethyldisiloxane, hexaethyldisiloxane, octamethyltrisiloxane, decamethyltetrasiloxane, dodecamethylpentasiloxane, tetradecamethylhexasiloxane, octamethylcyclotetrasiloxane, and octamethylcyclopentasiloxane are particularly preferred.

[0302] 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.

[0303] The layer formation of the surface treatment agent is preferably carried out so that the surface treatment agent of the present disclosure is present in the layer together with a catalyst for hydrolysis and dehydration condensation. Conveniently, in the case of a 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 a dry coating method, the surface treatment agent of the present disclosure to which the catalyst has been added may be directly subjected to vapor deposition (usually vacuum deposition), or a pellet-shaped material impregnated with the surface treatment agent of the present disclosure to which the catalyst has been added may be subjected to vapor deposition (usually vacuum deposition) on a porous metal such as iron or copper.

[0304] 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 its 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. Examples of acid catalysts that can be used include acetic acid, formic acid, trifluoroacetic acid, hydrochloric acid, nitric acid, sulfuric acid, phosphoric acid, sulfonic acid, methanesulfonic acid, p-toluenesulfonic acid, etc. Examples of base catalysts that can be used include ammonia, sodium hydroxide, potassium hydroxide, and organic amines such as triethylamine and diethylamine. Examples of transition metals, aliphatic amine compounds, and aromatic amine compounds are the same as those described above.

[0305] The surface treatment layer included in the article of the present disclosure has both high abrasion resistance and fingerprint wiping properties. In addition to high abrasion resistance, the surface treatment layer may have water repellency, oil repellency, antifouling properties (e.g., preventing adhesion of stains such as fingerprints), waterproof properties (preventing water penetration into electronic components, etc.), surface slipperiness (or lubricity, e.g., ease of wiping off stains such as fingerprints and excellent tactile feel), chemical resistance, etc., depending on the composition of the surface treatment agent used, and can be suitably used as a functional thin film.

[0306] Therefore, the present disclosure also relates to an optical material having the above-described surface treatment layer as the outermost layer.

[0307] Preferred examples of the optical material include optical materials related 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 EL displays, inorganic thin-film EL dot matrix displays, rear projection displays, vacuum fluorescent displays (VFDs), and field emission displays (FEDs), or protective plates for such displays, or displays whose surfaces have been treated with an anti-reflection film.

[0308] The article of the present disclosure may be, but is not particularly limited to, an optical member. Examples of optical members include lenses for eyeglasses and the like; front protective 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 of optical discs such as Blu-ray (registered trademark) discs, DVD discs, CD-Rs, and MOs; optical fibers; and the display surfaces of watches and clocks.

[0309] The article of the present disclosure may also be a medical device or medical material. The article having a layer obtained by the present disclosure may also be an automobile interior or exterior component. 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.

[0310] The thickness of the layer is not particularly limited. In the case of optical members, 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.

[0311] 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.

[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 its partial condensates can be converted into silicon oxide by dehydration condensation. Alkali metal silicates can be converted into silicic acid or its partial condensates by the addition of an acid or a cation exchange resin, and the resulting silicic acid or its partial condensates can then be dehydration condensed into silicon oxide. Examples of the hydrolyzable group in a silane compound having a hydrolyzable group bonded to a silicon atom include an alkoxy group and a chlorine atom. The hydrolyzable group in the silane compound can be hydrolyzed to a hydroxyl group, and the resulting silanol compound can be dehydration condensed to form silicon oxide. Examples of silane compounds having a hydrolyzable group bonded to a silicon atom include alkoxysilanes such as tetraalkoxysilanes and alkyltrialkoxysilanes, and tetrachlorosilane.

[0313] Examples of the alkali metal source include alkali metal hydroxides, water-soluble alkali metal salts, etc. Examples of the water-soluble alkali metal salts include alkali metal carbonates, alkali metal hydrogencarbonates, alkali metal hydrochlorides, alkali metal nitrates, etc. As the alkali metal source, alkali metal hydroxides and alkali metal carbonates are preferred.

[0314] 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 resulting silicon oxide. Therefore, by adjusting the amount of the remaining alkali metal, silicon oxide containing a desired amount of alkali metal atoms can be obtained.

After leaving the mixture to stand for over 12 hours, approximately 1 mL was collected while stirring vigorously with a magnetic stirrer and spin-coated onto a chemically strengthened glass substrate (Corning Gorilla Glass, 0.7 mm thick). The substrate was heated at 60°C for 5 minutes to completely remove the unnecessary diluent methoxypropanol. This was used as a master for pseudo-fingerprint transfer. Next, the smaller end (16 mm diameter) of a No. 4 silicone rubber stopper was pressed against the master for 10 seconds with a load of 4.9 N to transfer the pseudo-fingerprint component to the edge of the transfer material. Next, the edge of the transfer material was pressed against the surface of each sample with a load of 4.9 N for 10 seconds to transfer the pseudo-fingerprint component. Next, the pseudo-fingerprints on each sample were wiped off using the following procedure. Using a Bemcot M-3II (product name, manufactured by Asahi Kasei Corporation) as an abrader, the sample was rubbed back and forth 10 times at a speed of 60 rpm and a load of 1 kg / 3 cm2. The degree of fingerprint smearing after wiping was then measured using a haze meter (manufactured by Nippon Denshoku Industries Co., Ltd., NDH7000SPII) in accordance with the JIS K7136 (2000 edition) standard. The difference in haze value from an area with no fingerprints was calculated and evaluated using the following three-point scale. ◎ (Excellent): Δ haze is less than 0.5%. ◯ (Good): Δ haze is 0.5% or more and less than 1%. × (bad): Δ haze is 1% or more.
