[0142] Advantages of the Invention

[0143] According to the present invention, there is provided a compound capable of forming a surface treatment layer having low visibility of attached fingerprints and high friction durability. Detailed Embodiments

[0144] As used in this specification, a "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 group, sulfonyl group, siloxane, carbonyl group, carbonyloxy group, etc. at the terminal or in the molecular chain of the hydrocarbon group. Among them, when only "organic group" is mentioned, it means a monovalent organic group. In addition, a "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. The same applies to trivalent or higher-valent organic groups, which mean groups obtained by removing a specified number of hydrogen atoms from an organic group.

[0145] As used in this specification, a "hydrocarbon group" is a group containing carbon and hydrogen, and refers to a group obtained by removing a hydrogen atom from a hydrocarbon. The hydrocarbon group is not particularly limited, and examples thereof include C1- 20 hydrocarbon groups, such as aliphatic hydrocarbon groups, aromatic hydrocarbon groups, etc. The above-mentioned "aliphatic hydrocarbon group" can be any of linear, branched or cyclic, and can also be any of saturated or unsaturated. In addition, the hydrocarbon group may contain one or more ring structures. The hydrocarbon group may also be substituted with one or more substituents.

[0146] As used in this specification, the substituents of a "hydrocarbon group" are not particularly limited. For example, they may be selected from halogen atoms, C 1－6 alkyl groups that can be substituted with one or more halogen atoms, C 2－6 alkenyl groups, C 2－6 alkynyl groups, C 3－10 cycloalkyl groups, C 3－10 unsaturated cycloalkyl groups, 5- to 10-membered heterocyclic groups, 5- to 10-membered unsaturated heterocyclic groups, C 6﹣10 aryl groups, and 5- to 10-membered heteroaryl groups, and one or more groups thereof.

[0147] As used in this specification, a "hydrolyzable group" refers to a group that can undergo a hydrolysis reaction, that is, a group that can be detached from the main skeleton of a compound through a hydrolysis reaction. Examples of hydrolyzable groups include -OR h , -OCOR h , -O-N=CR h 2, -NR h 2, -NHR h , -NCO or halogen (in these formulas, R h represents a substituted or unsubstituted alkyl group having 1 to 4 carbon atoms), etc., and preferably -OR h (i.e., an alkoxy group). R hExamples include: unsubstituted alkyl groups such as methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl; substituted alkyl groups such as chloromethyl. Among these, alkyl groups are preferred, unsubstituted alkyl groups are particularly preferred, and methyl or ethyl are more preferred.

[0603] (Article)

[0604] Hereinafter, the article of the present invention will be described.

[0605] The article of the present invention includes a substrate and a layer (surface treatment layer) formed on the surface of the substrate by the surface treatment agent of the present invention.

[0606] Substrates that can be used in the present invention can be composed of, for example, glass, resin (natural or synthetic resin, for example, can be common plastic materials), metal, ceramic, semiconductor (such as silicon, germanium, etc.), fiber (fabric, non-woven fabric, etc.), fur, leather, wood, ceramics, stone, etc., building materials, sanitary products, any suitable materials.

[0607] For example, in the case where 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, etc. Additionally, in the case where the article to be manufactured is an optical component, a certain layer (or film) may also be formed on the surface (outermost layer) of the substrate, such as a hard coat or an antireflection layer, etc. The antireflection layer can be any one of a single-layer antireflection layer and a multilayer antireflection layer. As examples of inorganic substances that can be used as the antireflection layer, SiO2, SiO, ZrO2, TiO2, TiO, Ti2O3, Ti2O5, Al2O3, Ta2O5, Ta3O5, Nb2O5, HfO2, Si3N4, CeO2, MgO, Y2O3, SnO2, MgF2, WO3, etc. can be cited. These inorganic substances can be used alone, or two or more of them can be combined (for example, to form a mixture) and used. In the case of forming a multilayer antireflection layer, it is preferable to use SiO2 and / or SiO in its outermost layer. In the case where the article to be manufactured is an optical glass component for a touch panel, a transparent electrode may be provided on a part of the surface of the substrate (glass), for example, a thin film of indium tin oxide (ITO) or indium zinc oxide, etc. is used. Additionally, in the substrate, depending on its specific specifications, etc., an insulating layer, an adhesive layer, a protective layer, a decorative frame layer (I-CON), a fogging film layer, a hard coat film layer, a polarizing film, a retardation film, and a liquid crystal display module, etc. may also be provided.

[0608] The shape of the above-mentioned substrate is not particularly limited, and for example, it can be in the form of a plate, a film, or other forms. Additionally, the surface area of the substrate on which the surface treatment layer is to be formed only needs to be at least a part of the substrate surface, and can be appropriately determined according to the use and specific specifications of the article to be manufactured, etc.

[0609] In one mode, as such a substrate, at least a surface portion thereof can be formed of a material that inherently has hydroxyl groups. As such materials, glass can be cited, and metals (especially base metals), ceramics, semiconductors, etc. that can form a natural oxide film or a thermal oxide film on the surface can also be cited. Or, in the case of a resin, etc., when the hydroxyl groups are insufficient or not present originally, by performing a certain pretreatment on the substrate, hydroxyl groups can be introduced onto the surface of the substrate or the hydroxyl groups can be increased. As examples of such pretreatment, plasma treatment (such as corona discharge) or ion beam irradiation can be cited. In order to be able to introduce hydroxyl groups onto the substrate surface or increase the hydroxyl groups and purify the substrate surface (remove foreign substances, etc.), plasma treatment is also suitable. Additionally, as other examples of such pretreatment, the following methods can be cited: using the LB method (Langmuir-Blodgett method) or chemical adsorption method, etc., a surface adsorbent having a carbon-carbon unsaturated bond group is pre-formed in the form of a monolayer film on the substrate surface, and then, in an atmosphere containing oxygen and nitrogen, etc., the unsaturated bond is broken.

[0610] In another mode, as such a substrate, at least its surface portion may be formed of an organosilicon compound having one or more other reactive groups, such as an Si—H group, or a material containing an alkoxysilane.

[0611] In a preferred mode, the above-mentioned substrate is glass. As such glass, sapphire glass, soda-lime glass, alkali aluminosilicate glass, borosilicate glass, non-alkali 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.

[0612] In one mode, the article of the present invention may have a silicon oxide-containing intermediate layer 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.

[0613] In a preferred mode, the above-mentioned intermediate layer may further contain an alkali metal in addition to containing silicon oxide.

[0614] As the above-mentioned alkali metal, for example, lithium, sodium, potassium, etc. can be cited. The above-mentioned alkali metal is preferably sodium.

[0615] The thickness of the intermediate layer is not particularly limited, and is preferably 1 to 200 nm, particularly preferably 1 to 20 nm. By making the thickness of the intermediate layer above the lower limit value of the above range, the effect of improving the adhesiveness by the intermediate layer is better.

[0616] The concentration of alkali metal atoms in the intermediate layer can be measured by various surface analysis devices, such as TOF-SIMS, XPS, XRF, etc.

[0617] The ratio of alkali metal atoms to all atoms in the entire intermediate layer can be obtained by depth analysis of XPS using ion sputtering, and is carried out by alternately repeating the measurement by XPS and surface etching by ion sputtering using an ion gun built in the XPS apparatus.

[0618] In the intermediate layer, regarding 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, after obtaining the distribution curve of the concentration of alkali metal atoms in the depth direction by depth analysis of TOF-SIMS (time-of-flight secondary ion mass spectrometry) using ion sputtering, the average value of the alkali metal atom concentration on the distribution curve is calculated and obtained. The depth analysis of TOF-SIMS using ion sputtering is carried out by alternately repeating the measurement by TOF-SIMS and surface etching by ion sputtering using an ion gun built in the TOF-SIMS apparatus.

[0619] An article of the present invention can be manufactured by forming a layer of the surface treatment agent of the present invention on the surface of the above-mentioned substrate and then, if necessary, subjecting this layer to post-treatment to form a layer with the surface treatment agent of the present invention.

[0620] The formation of the layer of the surface treatment agent of the present invention can be carried out by applying the above-mentioned surface treatment agent to the surface in a manner that covers the substrate surface. The covering method is not particularly limited. For example, a wet covering method and a dry covering method can be used.

[0621] Examples of the wet covering method include dip coating, spin coating, flow coating, spray coating, roll coating, gravure coating, wipe coating, squeegee coat method, die coating, inkjet, casting method, Langmuir-Blodgett method, and similar methods.

[0622] Examples of the dry covering method include vapor deposition (usually vacuum vapor deposition), sputtering, CVD, and similar methods. Specific examples of the vapor deposition method (usually the vacuum vapor deposition method) include resistance heating, electron beam, high-frequency heating using microwaves, ion beam, and similar methods. Specific examples of the CVD method include plasma-CVD, optical CVD, thermal CVD, and similar methods.

[0625] In the case of using the dry coating method, the surface treatment agent of the present invention can be directly applied to the dry coating method, or can also be applied to the dry coating method after being diluted with the above-mentioned solvent.

[0626] The formation of the layer of the surface treatment agent is preferably carried out in such a way that the surface treatment agent of the present invention coexists with a catalyst for hydrolysis and dehydration condensation in the layer. In short, in the case of using the wet coating method, after diluting the surface treatment agent of the present invention with a solvent, before applying it to the surface of the substrate, a catalyst can be added to the diluted solution of the surface treatment agent of the present invention. In the case of using the dry coating method, the surface treatment agent of the present invention after adding the catalyst can be directly subjected to evaporation coating (usually vacuum evaporation coating), 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 substance, and the obtained granular substance is used for evaporation coating (usually vacuum evaporation coating) treatment.

[0627] The catalyst can be any suitable acid or base, transition metal (such as Ti, Ni, Sn, Zr, Al, B, etc.), sulfur-containing compound having a non-bonding electron pair in the molecular structure, or nitrogen-containing compound (such as sulfoxide compound, aliphatic amine compound, aromatic amine compound, phosphoric acid amide compound, amide compound, urea compound), etc. As the 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. can be used. In addition, as the base catalyst, for example, ammonia, sodium hydroxide, potassium hydroxide, organic amines such as triethylamine, diethylamine, etc. can be used. The same substances as those described above can be cited for the transition metal, aliphatic amine compound and aromatic amine compound.

[0628] The surface treatment layer included in the article of the present invention has both high wear durability and fingerprint wiping property. In addition, in addition to high wear durability, the above surface treatment layer can also have water repellency, oil repellency, antifouling property (such as preventing the attachment of stains such as fingerprints), waterproof property (preventing water from infiltrating into electronic components, etc.), surface slidability (or lubricity, such as the wiping property of stains such as fingerprints, excellent finger touch), chemical resistance, etc., depending on the composition of the surface treatment agent used, and is suitable for use as a functional film.

[0629] Therefore, the present invention also relates to an optical material having the above surface treatment layer on the outermost layer.

[0630] As the optical material, in addition to the optical materials related to displays as exemplified below, various optical materials are preferably cited, such as: 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 type displays, fluorescent display tubes (VFD), field emission displays (FED, Field Emission Display), etc. displays or protective plates of these displays, or materials having an antireflection film treatment on the surface thereof.

[0631] The article of the present invention is not particularly limited and can be an optical component. Examples of the optical component can be cited as follows: lenses for glasses, etc.; front protective plates, antireflection plates, polarizing plates, antiglare plates of displays such as PDP, LCD, etc.; touch panel sheets of devices such as mobile phones, portable information terminals, etc.; disk surfaces of Blu-ray (registered trademark) discs, DVD discs, CD-R, MO, etc.; optical fibers; display surfaces of watches, etc.

[0632] In addition, the article of the present invention may also be a medical device or medical material. In addition, an article having the layer obtained by the present invention may also be an interior or exterior automotive material. Examples of the exterior material may include the following: window, lamp cover, and outside vehicle camera cover. Examples of the interior material may include the following: instrument panel cover, navigation system touch panel, and decorative interior material.

[0633] The thickness of the above layer is not particularly limited. In the case of an optical component, from the viewpoints of optical performance, wear durability, and antifouling property, it is preferable that the thickness of the above layer is, for example, in the range of 1 to 50 nm, preferably 1 to 30 nm, more preferably 1 to 15 nm.

[0634] The above-mentioned silica-containing intermediate layer can be formed by applying a silica precursor to the surface of a substrate. In the case where the intermediate layer contains an alkali metal, the above-mentioned intermediate layer can be formed by applying a composition containing a silica precursor and an alkali metal source to the surface of a substrate.

[0635] Examples of the above silica 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 or its partial condensates can be dehydrated and condensed to form silica; alkali metal silicates can form silicic acid or its partial condensates by using an acid or a cation exchange resin, and the resulting silicic acid or its partial condensates can be dehydrated and condensed to form silica. 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. By hydrolyzing the hydrolyzable group of the silane compound to form a hydroxyl group and dehydrating and condensing the resulting silanol compound, silica can be formed. Examples of the silane compound having a hydrolyzable group bonded to a silicon atom include alkoxysilanes such as tetraalkoxysilane and alkyltrialkoxysilane, and silicon tetrachloride.

[0636] Examples of the above 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. As the alkali metal source, alkali metal hydroxides and alkali metal carbonates are preferable.

[0637] Among them, alkali metal silicates can be used as both a silica precursor and an alkali metal source. Although alkali metal silicates can form silica via silicic acid, a small amount of alkali metal will remain in the resulting silica. Therefore, by adjusting the amount of the remaining alkali metal, silica containing a specified amount of alkali metal atoms can be obtained.

[0638] The thickness of the above 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 further preferably 3 to 10 nm.

[0639] The compounds, surface treatment agents, and articles of the present invention have been described in detail above. However, the compounds, surface treatment agents, articles, etc. of the present invention are not limited to the examples illustrated above.
