[0007] According to the present disclosure, there is provided a silane compound capable of forming a surface treatment layer having excellent friction durability. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] 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. The derivative of a hydrocarbon group 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. 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.

[0009] 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 1-20 Examples 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. The hydrocarbon group may be substituted with one or more substituents.

[0010] As used herein, examples of the substituent of the "hydrocarbon group" include, but are not limited to, 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, 5-10 membered heterocyclyl groups, 5-10 membered unsaturated heterocyclyl groups, C 6-10Examples of the alkyl group include one or more groups selected from aryl groups and 5- to 10-membered heteroaryl groups.

[0011] As used herein, the term "hydrolyzable group" refers to a group that can undergo hydrolysis, i.e., a group that can be removed from the main skeleton of a compound by hydrolysis. Examples of hydrolyzable groups include -OR h , -OCOR h , -ON=CR h 2, -NR h 2, -NHR h , -NCO, 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. Among these, alkyl groups, particularly unsubstituted alkyl groups, are preferred, with methyl and ethyl groups being more preferred.

[0012] As used herein, the term "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 1-3 cyclic aromatic group, and specific examples thereof include divalent groups obtained by removing 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. [ka]

[0335] Other examples of the other components include tetraethoxysilane, methyltrimethoxysilane, 3-aminopropyltrimethoxysilane, 3-glycidoxypropyltrimethoxysilane, and methyltriacetoxysilane in addition to the above.

[0336] In addition to the components described above, the surface treatment agent of the present disclosure may contain trace amounts of impurities such as Pt, Rh, Ru, 1,3-divinyltetramethyldisiloxane, triphenylphosphine, NaCl, KCl, and silane condensates.

[0337] In one embodiment, the surface treatment agent of the present disclosure is for dry coating methods, preferably vacuum deposition.

[0338] In one embodiment, the surface treatment agent of the present disclosure is for use in a wet coating method, preferably dip coating.

[0339] The surface treatment agent of the present disclosure can be impregnated into a porous material, such as a porous ceramic material or a metal fiber, such as steel wool, and formed into a pellet. The pellet can be used, for example, in vacuum deposition.

[0340] The articles of the present disclosure are described below.

[0341] 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.

[0342] 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.

[0343] 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.

[0344] 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.

[0345] 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, and then the unsaturated bond is cleaved in an atmosphere containing oxygen, nitrogen, etc.

[0346] 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.

[0347] In a preferred embodiment, the substrate is glass, preferably sapphire glass, soda-lime glass, alkali aluminosilicate glass, borosilicate glass, alkali-free glass, crystal glass, or quartz glass, more preferably chemically strengthened soda-lime glass, chemically strengthened alkali aluminosilicate glass, or chemically bonded borosilicate glass.

[0348] 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.

[0349] 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.

[0350] 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.

[0415] <Evaluation> [Wear resistance evaluation] The higher the static contact angle of water after the abrasion resistance test, the smaller the deterioration of performance due to friction and the more excellent the abrasion resistance. (Initial evaluation) As an initial evaluation (number of frictions: 0), after the surface treatment layer was formed, excess water on the surface was wiped off, and then the static contact angle of water was measured. (Evaluation after abrasion resistance test) The surface treatment layer thus formed was rubbed back and forth with a rubbing tester (manufactured by Imoto Manufacturing Co., Ltd.) under the following conditions. After a certain number of rubs, the static contact angle of water was measured. The results are shown in the table below. Friction element: BEMCOT M-3II (product name, manufactured by Asahi Kasei Corporation) Travel distance (one way): 60mm Traveling speed: 8,400mm / min Load: 100g / 3cm 2
