[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 in which one more hydrogen atom has been eliminated from an organic group. Similarly, a trivalent or higher organic group refers to a group in which a predetermined number of hydrogen atoms have been eliminated 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 group, 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 , —O—N═CR ｈ ２ , -NR ｈ ２ , -NHR ｈ , —NCO, halogen (wherein R ｈ is a substituted or unsubstituted C １－４ alkyl group), 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. Among these, alkyl groups, particularly unsubstituted alkyl groups, are preferred, with methyl and ethyl groups being more preferred.

[0011] As used herein, an "arylene group" refers to a divalent aromatic group. The arylene group may be a monocyclic aromatic group or a polycyclic aromatic group. The arylene group is, for example, a divalent monocyclic to tricyclic aromatic group, and specific examples thereof include divalent groups obtained by eliminating two hydrogen atoms from benzene, naphthalene, anthracene, fluorene, and phenanthrene, as shown below. The arylene group may be substituted with one or more substituents. The bonding position is arbitrary.

[0451] In one embodiment, the surface treatment agent (coating liquid) of the present disclosure is for a dry coating method, preferably vacuum deposition.

[0452] In one embodiment, the surface treatment agent (coating liquid) of the present disclosure is for use in a wet coating method, preferably dip coating.

[0453] The surface treatment agent (coating liquid) of the present disclosure can be impregnated into a porous substance, such as a porous ceramic material or a metal fiber, such as a cotton-like mass of steel wool, to form pellets, which can be used for vacuum deposition, for example.

[0454] The composition of the present disclosure is preferably used as a surface treatment agent or as a component of a surface treatment agent.

[0455] The articles of the present disclosure are described below.

[0456] 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 (coating liquid) of the present disclosure.

[0457] 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.

[0458] For example, when 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. When the article to be manufactured is an optical component, some layer (or film), such as a hard coat layer or an anti-reflection layer, may be formed on the surface (outermost layer) of the substrate. The anti-reflection layer may be either a single-layer anti-reflection layer or a multi-layer anti-reflection layer. Examples of inorganic materials that can be used for the anti-reflection layer include 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 , W.O. ３ These inorganic substances may be used alone or in combination of two or more (for example, as a mixture). In the case of a multi-layer antireflection layer, the outermost layer may contain SiO ２and / or SiO is preferably used. When the article to be manufactured is an optical glass component 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 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 atomization film layer, a hard coating film layer, a polarizing film, a phase difference film, a liquid crystal display module, or the like, depending on its specific specifications.

[0459] 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.

[0460] 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, in cases where the presence of hydroxyl groups is insufficient, such as in resins, or in cases where hydroxyl groups are not originally present, some kind of pretreatment can be performed on the substrate to introduce or increase the number of hydroxyl groups on the substrate 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 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 preliminarily formed in the form of a monomolecular film on the substrate surface by the Langmuir-Blodgett method (LB method) or chemical adsorption method, and then the unsaturated bonds are cleaved in an atmosphere containing oxygen, nitrogen, or the like.

[0461] In another embodiment, at least the surface portion of such a substrate may be made of a material containing another reactive group, such as a silicone compound having one or more Si—H groups, or an alkoxysilane.

[0462] 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, quartz glass, or crystallized glass, with chemically strengthened soda-lime glass, chemically strengthened alkali aluminosilicate glass, and chemically bonded borosilicate glass being particularly preferred.

[0463] 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.

[0464] In a preferred embodiment, the intermediate layer may contain an alkali metal in addition to silicon oxide.

[0465] Examples of the alkali metal include lithium, sodium, potassium, etc. The alkali metal is preferably sodium.

[0466] 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.

[0467] The alkali metal atom concentration in the intermediate layer can be measured by various surface analysis devices, such as TOF-SIMS, XPS, and XRF.

[0468] 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 alternately repeating XPS measurement and surface etching by ion sputtering using an ion gun built into the XPS apparatus.

[0469] 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. The 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.

[0470] 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.

[0471] 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.

[0472] 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.

[0473] 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, etc., ion beam, and similar methods. Specific examples of CVD methods include plasma-CVD, optical CVD, thermal CVD, and similar methods.

[0474] Furthermore, coating by atmospheric pressure plasma method is also possible.

[0481] 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 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.

[0482] 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.

[0483] 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.

[0484] 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, 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.

[0485] An X-ray photoelectron spectroscopy (XPS) instrument, manufactured by ULVAC-PHI, Inc., PHI5000 VersaProbe II, can be used to measure the atomic composition and atomic ratios of the surface treatment layer. XPS analysis conditions include a monochromated AlKα X-ray source at 25 W, a photoelectron detection area of ​​1400 μm × 300 μm, a photoelectron detection angle in the range of 20 to 90 degrees (e.g., 20, 45, or 90 degrees), and a pass energy of 23.5 eV. Gas cluster ion beams or Ar ions can be used for sputtering. Using the above instrument 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 intermediate layer.

[0486] Depth analysis can also be performed. Measurement conditions for XPS analysis include using a monochromated AlKα ray at 25 W as the X-ray source, a photoelectron detection area of ​​1400 μm × 300 μm, a photoelectron detection angle in the range of 20 to 90 degrees (e.g., 20, 45, or 90 degrees), and a pass energy of 23.5 eV. Ar ions, gas cluster ions, or C ions can be used as sputtering ions. Sputtering can be performed by etching 1 to 100 nm, and the composition of the coating film at each etching depth can be obtained.

[0487] The detection depth can be adjusted appropriately by adjusting the photoelectron detection angle in the XPS analysis. For example, a shallow angle close to 20 degrees can achieve a detection depth of about 3 nm, while a deep angle close to 90 degrees can achieve a detection depth of about 10-odd nm.

[0488] 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.

[0489] 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.

[0490] Examples of the alkali metal source include alkali metal hydroxides and water-soluble alkali metal salts. Examples of the water-soluble alkali metal salts include alkali metal carbonates, alkali metal hydrogencarbonates, alkali metal hydrochlorides, and alkali metal nitrates. Examples of the alkali metal source include alkali metal hydroxides and alkali metal carbonates, more preferably alkali metal hydroxides, and even more preferably Na.

[0491] 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.

[0492] 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 even more preferably 3 to 10 nm.

[0493] The compounds, compositions, and articles of the present disclosure have been described in detail above. However, the compounds, compositions, and articles of the present disclosure are not limited to those exemplified above.

[0552] (Abrasion Resistance Evaluation) <Initial Evaluation> For the initial evaluation (0 abrasion times), after the formation of the surface treatment layer, the excess water on the surface was wiped off, and then the static contact angle of water was measured.
