[0130] Examples of the perfluoro(poly)ether compound represented by the above general formula (3) include compounds represented by either of the following general formulas (3a) and (3b) (which may be one type or a mixture of two or more types): Rf 5 -(OCF2CF2CF2) b” -Rf 6 (3a) Rf 5 -(OCF2CF2CF2CF2) a” -(OCF2CF2CF2) b” -(OCF2CF2) c” -(OCF2) d” -Rf 6 (3b) In these formulas, Rf 5 and Rf 6is as defined above; in formula (3a), b" is an integer of 1 or more and 100 or less; in formula (3b), a" and b" are each independently an integer of 0 or more and 30 or less, and c" and d" are each independently an integer of 1 or more and 300 or less. The order of occurrence of each repeating unit enclosed in parentheses with the subscripts a", b", c", and d" is arbitrary in the formula.

[0131] From another perspective, fluorine-containing oils are those represented by the general formula Rf 3 -F(where Rf 3 is C 5-16 It may be a compound represented by the formula: wherein R is a perfluoroalkyl group.) It may also be a chlorotrifluoroethylene oligomer.

[0132] The fluorine-containing oil may have an average molecular weight of 500 to 10000. The molecular weight of the fluorine-containing oil can be measured using GPC.

[0133] The fluorinated oil may be contained in an amount of, for example, 0 to 50% by mass, preferably 0 to 30% by mass, and more preferably 0 to 5% by mass, relative to the composition of the present disclosure. In one embodiment, the composition of the present disclosure is substantially free of fluorinated oil. "Substantially free of fluorinated oil" means that the composition does not contain any fluorinated oil at all, or may contain a very small amount of fluorinated oil.

[0134] In one embodiment, the average molecular weight of the fluorinated oil may be larger than the average molecular weight of the triazine compound of the present disclosure. By adjusting the average molecular weight to such an extent, it is possible to obtain superior abrasion resistance and surface slipperiness, particularly when the surface treatment layer is formed by vacuum deposition.

[0135] In one embodiment, the average molecular weight of the fluorinated oil may be smaller than the average molecular weight of the triazine compound of the present disclosure. By setting the average molecular weight in this range, it is possible to form a cured product having high abrasion resistance and high surface slippage while suppressing a decrease in the transparency of the surface treatment layer obtained from such a compound.

[0136] The fluorine-containing oil contributes to improving the surface slip properties of the layer formed from the composition of the present disclosure.

[0137] As the silicone oil, for example, a linear or cyclic silicone oil having 2,000 or less siloxane bonds can be used. The linear silicone oil may be a so-called straight silicone oil or a modified silicone oil. Examples of straight silicone oils include dimethyl silicone oil, methylphenyl silicone oil, and methylhydrogen silicone oil. Examples of modified silicone oils include straight silicone oils modified with alkyl, aralkyl, polyether, higher fatty acid ester, fluoroalkyl, amino, epoxy, carboxyl, alcohol, etc. Examples of cyclic silicone oils include cyclic dimethylsiloxane oil.

[0138] In the composition of the present disclosure, such silicone oil may be contained in an amount of, for example, 0 to 300 parts by mass, preferably 50 to 200 parts by mass, relative to a total of 100 parts by mass of the triazine compounds of the present disclosure (if two or more types are used, the total of these, the same applies hereinafter).

[0139] The silicone oil contributes to improving the surface slipperiness of the surface treatment layer.

[0140] Examples of the alcohols include alcohols having 1 to 6 carbon atoms which may be substituted with one or more fluorine atoms, such as methanol, ethanol, isopropanol, tert-butanol, CF3CH2OH, CF3CF2CH2OH, and (CF3)2CHOH. Addition of these alcohols to the composition improves the stability of the composition and also improves the compatibility of the triazine compound with the solvent.

[0141] The alcohol is preferably 2,2,3,3,3-pentafluoro-1-propanol or 2,2,2-trifluoroethanol.

[0142] Examples of the catalyst include acids (for example, acetic acid, trifluoroacetic acid, etc.), bases (for example, ammonia, triethylamine, diethylamine, etc.), and transition metals (for example, Ti, Ni, Sn, etc.).

[0143] The catalyst promotes the hydrolysis and dehydration condensation of the triazine compound of the present disclosure, and promotes the formation of the layer formed by the composition of the present disclosure.

[0144] In addition to the above, other components include, for example, tetraethoxysilane, methyltrimethoxysilane, 3-aminopropyltrimethoxysilane, 3-glycidoxypropyltrimethoxysilane, and methyltriacetoxysilane.

[0145] 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.

[0146] In addition to the components described above, the composition of the present disclosure may contain trace amounts of impurities such as Pt, Rh, Ru, 1,3-divinyltetramethyldisiloxane, triphenylphosphine, NaCl, KCl, and silane condensates.

[0147] The articles of the present disclosure are described below.

[0148] The article of the present disclosure includes a substrate and a layer (surface treatment layer) formed on the surface of the substrate from the composition of the present disclosure.

[0149] 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.

[0150] 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.

[0151] 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.

[0152] 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.

[0153] 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.

[0154] 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.

[0155] The article of the present disclosure can be produced by forming a layer of the composition of the present disclosure on the surface of the substrate, and optionally post-treating the layer, thereby forming a layer from the composition of the present disclosure.

[0156] The layer formation of the composition of the present disclosure can be carried out by applying the composition to the surface of a substrate so as to cover the surface. The coating method is not particularly limited. For example, a wet coating method or a dry coating method can be used.

[0157] Examples of wet coating methods include dip coating, spin coating, flow coating, spray coating, roll coating, gravure coating, and similar methods.

[0158] 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.

[0159] Furthermore, coating by atmospheric pressure plasma method is also possible.

[0160] When using the wet coating method, the composition of the present disclosure may be diluted with a solvent and then applied to the surface of a substrate. From the viewpoints of the stability of the composition of the present disclosure and the volatility of the solvent, the following solvents are preferably used: perfluoroaliphatic hydrocarbons having 5 to 12 carbon atoms (e.g., perfluorohexane, perfluoromethylcyclohexane, and perfluoro-1,3-dimethylcyclohexane); polyfluoroaromatic hydrocarbons (e.g., bis(trifluoromethyl)benzene); polyfluoroaliphatic hydrocarbons (e.g., CF 13CH2CH3 (e.g., Asahiklin (registered trademark) AC-6000 manufactured by Asahi Glass Co., Ltd.), 1,1,2,2,3,3,4-heptafluorocyclopentane (e.g., Zeorora (registered trademark) H manufactured by Zeon Corporation); hydrofluoroethers (HFEs) (e.g., perfluoropropyl methyl ether (C3F7OCH3) (e.g., Novec (trademark) 7000 manufactured by Sumitomo 3M Limited), perfluorobutyl methyl ether (C4F9OCH3) (e.g., Novec (trademark) 7100 manufactured by Sumitomo 3M Limited), Alkyl perfluoroalkyl ethers (the perfluoroalkyl group and alkyl group may be linear or branched) such as perfluorobutyl ethyl ether (C4F9OC2H5) (e.g., Novec™ 7200 manufactured by Sumitomo 3M Limited) and perfluorohexyl methyl ether (C2F5CF(OCH3)C3F7) (e.g., Novec™ 7300 manufactured by Sumitomo 3M Limited), or CF3CH2OCF2CHF2 (e.g., Asahiklin™ AE-3000 manufactured by Asahi Glass Co., Ltd.). These solvents can be used alone or as a mixture of two or more. Among them, hydrofluoroethers are preferred, with perfluorobutyl methyl ether (C4F9OCH3) and / or perfluorobutyl ethyl ether (C4F9OC2H5) being particularly preferred.

[0161] When the dry coating method is used, the composition of the present disclosure may be subjected to the dry coating method as it is, or may be diluted with the above-mentioned solvent before being subjected to the dry coating method.

[0162] The layer formation of the composition is preferably carried out so that the composition 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 composition of the present disclosure may be diluted with a solvent, and then a catalyst may be added to the diluted solution of the composition of the present disclosure immediately before application to the substrate surface. In the case of a dry coating method, the composition of the present disclosure to which the catalyst has been added may be directly vapor-deposited (usually vacuum vapor-deposited), or a pellet-shaped material impregnated with the composition of the present disclosure to a porous metal such as iron or copper may be vapor-deposited (usually vacuum vapor-deposited).

[0163] Any suitable acid or base can be used as the catalyst. Examples of acid catalysts that can be used include acetic acid, formic acid, and trifluoroacetic acid. Examples of base catalysts that can be used include ammonia and organic amines.

[0164] The surface treatment layer included in the article of the present disclosure has high abrasion resistance. In addition to high abrasion resistance, the surface treatment layer may have water repellency, oil repellency, antifouling properties (for example, preventing adhesion of stains such as fingerprints), waterproof properties (for example, preventing water penetration into electronic components), surface slipperiness (or lubricity, for example, ease of wiping off stains such as fingerprints and excellent tactile feel), chemical resistance, etc., depending on the composition of the composition used, and may be suitably used as a functional thin film.

[0165] Therefore, the present disclosure also relates to an optical material having the above-described surface treatment layer as the outermost layer.

[0166] 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.

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.

[0168] 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.

[0169] The thickness of the layer is not particularly limited. In the case of optical members, the thickness of the layer is preferably in the range of 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.

[0170] The article of the present disclosure has been described in detail above. However, the article and the method for manufacturing the article of the present disclosure are not limited to the examples given above. [Example]

The resulting coating film was irradiated with 600 mJ / cm of light containing 365 nm UV light under a nitrogen atmosphere. 2 Each hard coat material was cured to obtain a cured film (surface treatment layer). The initial properties of these cured films were measured.

The measurement results are shown in Table 2.

[0187] (static contact angle) The static contact angle was measured using a fully automatic contact angle meter, DropMaster 700 (Kyowa Interface Science Co., Ltd.), by dropping 2 μL of water from a microsyringe onto a horizontally placed substrate and taking a still image 1 second after the drop with a video microscope.

A load of 1,000 gf was then applied thereto. Then, with the load applied, the steel wool was reciprocated at a speed of 53.3 mm / sec (friction speed 40 rpm). The static contact angle (degrees) of water was measured every 1,000 reciprocations, and the evaluation was stopped when the measured contact angle became less than 100 degrees. The number of reciprocations at which the contact angle finally exceeded 100 degrees is shown in Table 2.
