[0118] [Surface Treatment Agent] In one embodiment, the surface treatment agent of the present disclosure comprises the compound of the present disclosure. Alternatively, the surface treatment agent of the present disclosure may comprise the compound of the present disclosure and a liquid medium. The surface treatment agent of the present disclosure may also be a composition of the present disclosure. A preferred embodiment of the liquid medium contained in the surface treatment agent of the present disclosure is the same as a preferred embodiment of the liquid medium contained in the composition of the present disclosure.

[0119] [Article] In one embodiment, the article of the Disclosure includes a substrate and a surface treatment layer disposed on the substrate and surface-treated with a surface treatment agent of the Disclosure.

[0120] The surface treatment layer may be formed on a part of the surface of the substrate or on the entire surface of the substrate. The surface treatment layer may be spread as a film on the surface of the substrate or may be scattered as dots. In the surface treatment layer, the compound of the present disclosure is included in a state in which hydrolysis of some or all of the reactive silyl groups has progressed and the dehydration condensation reaction of the silanol groups has progressed.

[0121] The thickness of the surface treatment layer is preferably 1 to 100 nm, and more preferably 1 to 50 nm. If the thickness of the surface treatment layer is 1 nm or more, the effects of the surface treatment are easily obtained.

[0125] The substrate may have one or both surfaces treated with a surface treatment such as corona discharge treatment, plasma treatment, or plasma graft polymerization treatment. A surface-treated substrate exhibits better adhesion to the surface-treated layer and improved abrasion resistance of the surface-treated layer. Therefore, it is preferable to apply the surface treatment to the surface of the substrate that comes into contact with the surface-treated layer. Furthermore, if a base layer is provided, as described later, a surface-treated substrate exhibits better adhesion to the base layer and improved abrasion resistance of the surface-treated layer. Therefore, if a base layer is provided, it is preferable to apply the surface treatment to the surface of the substrate that comes into contact with the base layer.

[0126] The surface treatment layer may be provided directly on the surface of the substrate, or a base layer may be provided between the substrate and the surface treatment layer. From the viewpoint of further improving the water repellency and abrasion resistance of the surface treatment layer, the article of the present disclosure preferably includes a substrate, a base layer disposed on the substrate, and a surface treatment layer disposed on the base layer and surface-treated with the surface treatment agent of the present disclosure.

[0127] The base layer is preferably a layer containing an oxide comprising silicon and at least one specific element selected from the group consisting of Group 1, Group 2, Group 4, Group 5, Group 13, and Group 15 elements of the periodic table.

[0128] The Group 1 elements of the periodic table (hereinafter also referred to as "Group 1 elements") refer to lithium, sodium, potassium, rubidium, and cesium. From the viewpoint of being able to form a surface treatment layer on the substrate more uniformly without defects, or from the viewpoint of further suppressing variations in the composition of the substrate between samples, lithium, sodium, and potassium are preferred as Group 1 elements, and sodium and potassium are more preferred. The substrate may contain two or more Group 1 elements.

[0129] The Group 2 elements of the periodic table (hereinafter also referred to as "Group 2 elements") refer to beryllium, magnesium, calcium, strontium, and barium. From the viewpoint of enabling the formation of a surface treatment layer on the substrate more uniformly and without defects, or of further suppressing variations in the composition of the substrate between samples, magnesium, calcium, and barium are preferred as Group 2 elements, with magnesium and calcium being more preferred. The substrate may contain two or more Group 2 elements.

[0130] The Group 4 elements of the periodic table (hereinafter also referred to as "Group 4 elements") refer to titanium, zirconium, and hafnium. From the viewpoint of forming a surface treatment layer on the substrate more uniformly and without defects, or from the viewpoint of further suppressing variations in the composition of the substrate between samples, titanium and zirconium are preferred as Group 4 elements, with titanium being more preferred. The substrate may contain two or more Group 4 elements.

[0131] The elements of Group 5 of the periodic table (hereinafter also referred to as "Group 5 elements") refer to vanadium, niobium, and tantalum.

The base layer may contain two or more Group 5 elements.

[0132] The elements of Group 13 of the periodic table (hereinafter also referred to as "Group 13 elements") refer to boron, aluminum, gallium, and indium. As Group 13 elements, boron, aluminum, and gallium are preferred, and boron and aluminum are more preferred, from the viewpoint of being able to form a surface treatment layer on the substrate layer more uniformly without defects, or from the viewpoint of further suppressing variations in the composition of the substrate layer between samples. The substrate layer may contain two or more Group 13 elements.

[0133] The elements of Group 15 of the periodic table (hereinafter also referred to as "Group 15 elements") refer to nitrogen, phosphorus, arsenic, antimony, and bismuth. From the viewpoint of forming a surface treatment layer on the substrate more uniformly and without defects, or from the viewpoint of further suppressing variations in the composition of the substrate between samples, phosphorus, antimony, and bismuth are preferred as Group 15 elements, and phosphorus and bismuth are more preferred. The substrate may contain two or more Group 15 elements.

[0134] The specific elements included in the base layer are preferably Group 1, Group 2, and Group 13 elements because they provide superior wear resistance to the surface treatment layer, more preferably Group 1 and Group 2 elements, and even more preferably Group 1 elements. The specific elements may consist of only one element or two or more elements.

[0135] The oxides contained in the sublayer may be a mixture of oxides of the above elements (silicon and specific elements) individually (for example, a mixture of silicon oxide and an oxide of a specific element), a composite oxide containing two or more of the above elements, or a mixture of oxides of the above elements individually and a composite oxide.

[0136] The ratio of the total molar concentration of specific elements in the substrate to the molar concentration of silicon in the substrate (specific element / silicon) is preferably 0.02 to 2.90, more preferably 0.10 to 2.00, and even more preferably 0.20 to 1.80, from the viewpoint of achieving superior wear resistance of the surface treatment layer. The molar concentration (mol%) of each element in the substrate can be measured, for example, by depth profiling analysis using X-ray photoelectron spectroscopy (XPS) with ion sputtering.

[0137] The substrate layer may be a single layer or multiple layers. The substrate layer may have irregularities on its surface. The thickness of the substrate layer is preferably 1 to 100 nm, more preferably 1 to 50 nm, and even more preferably 2 to 20 nm. If the thickness of the substrate layer is above the lower limit, the adhesion of the substrate layer to the surface treatment layer is further improved, and the abrasion resistance of the surface treatment layer is further improved. If the thickness of the substrate layer is below the upper limit, the abrasion resistance of the substrate layer itself is excellent. The thickness of the substrate layer is measured by cross-sectional observation of the substrate layer using a transmission electron microscope (TEM).

[0138] The underlayer can be formed, for example, by a vapor deposition method using a vapor deposition material, or by a wet coating method.

[0139] The vapor deposition material used in the vapor deposition method preferably contains silicon and oxides containing specific elements. Specific examples of the vapor deposition material's form include powder, molten material, sintered material, granulated material, and crushed material. From the viewpoint of ease of handling, molten material, sintered material, and granulated material are preferred. Here, molten material refers to a solid obtained by melting the vapor deposition material powder at a high temperature and then cooling and solidifying it. Sintered material refers to a solid obtained by firing the vapor deposition material powder. If necessary, a molded body may be used instead of the vapor deposition material powder by press-forming the powder. Granulated material refers to a solid obtained by kneading the vapor deposition material powder with a liquid medium (e.g., water, organic solvent) to obtain particles, and then drying the particles.

[0140] Vapor deposition materials can be manufactured by, for example, the following methods: - A method of obtaining a vapor deposition material powder by mixing silicon oxide powder and an oxide powder of a specific element. - A method of obtaining particles by kneading the vapor deposition material powder and water, and then drying the particles to obtain a vapor deposition material granule. - A method of obtaining a sintered body by drying a mixture of silicon-containing powder (e.g., silicon oxide powder, silica sand, silica gel), a powder containing a specific element (e.g., oxide powder of a specific element, carbonate, sulfate, nitrate, oxalate, hydroxide) and water, and then firing the dried mixture or a molded body formed by press molding therefrom. - A method of obtaining a molten body by melting silicon-containing powder (e.g., silicon oxide powder, silica sand, silica gel) and a powder containing a specific element (e.g., oxide powder of a specific element, carbonate, sulfate, nitrate, oxalate, hydroxide) at a high temperature, and then cooling and solidifying the molten material.

[0141] A specific example of a deposition method using deposition materials is the vacuum deposition method. The vacuum deposition method is a method in which the deposition material is evaporated in a vacuum chamber and deposited onto the surface of a substrate. The deposition temperature (for example, the temperature of the boat in which the deposition material is placed when using a vacuum deposition apparatus) is preferably 100 to 3,000°C, and more preferably 500 to 3,000°C. The deposition pressure (for example, the pressure in the chamber in which the deposition material is placed when using a vacuum deposition apparatus) is preferably 1 Pa or less, and more preferably 0.1 Pa or less. When forming a base layer using a deposition material, one deposition material may be used, or two or more deposition materials containing different elements may be used.

[0142] Specific examples of evaporation methods for deposition materials include the resistance heating method, in which the deposition material is melted and evaporated on a high-melting-point metal resistance heating boat, and the electron gun method, in which an electron beam is irradiated onto the deposition material to directly heat it, melt the surface, and evaporate it. The electron gun method is preferred as an evaporation method for deposition materials because it allows for localized heating, enabling the evaporation of high-melting-point substances, and because areas not exposed to the electron beam remain at low temperatures, eliminating the risk of reaction with the container or contamination by impurities. Multiple boats may be used for evaporation, or all deposition materials may be placed in a single boat. The deposition method may be co-deposition or alternating deposition. Specifically, examples include mixing silica and a specific element source in the same boat, co-deposition using silica and a specific element source in separate boats, and alternating deposition using separate boats. The deposition conditions and order are appropriately selected depending on the composition of the underlying layer.

[0143] In the wet coating method, it is preferable to form a base layer on the substrate by a wet coating method using a coating solution containing a silicon-containing compound, a compound containing a specific element, and a liquid medium.

Furthermore, when the article of this disclosure is an optical component, a functional layer such as a hard coat layer or an anti-reflective layer may be formed on the surface (outermost layer) of the substrate. The anti-reflective layer may be either a single-layer anti-reflective layer or a multi-layer anti-reflective layer. Examples of inorganic materials that can be used for the anti-reflective 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 , and WO 3 .

[0154] [Method for Producing Article] The method for producing an article of the present disclosure is, for example, a method of subjecting a substrate to surface treatment using the surface treatment agent of the present disclosure to produce an article having a surface treatment layer formed on the substrate. Examples of the surface treatment include dry coating methods and wet coating methods.

[0155] Examples of the dry coating method include techniques such as vacuum deposition, CVD, and sputtering. Among dry coating methods, the vacuum deposition method is preferred from the viewpoints of suppressing decomposition of the compound and the simplicity of the apparatus. During vacuum deposition, a pellet-shaped substance obtained by impregnating a porous metal such as iron or steel with the compound of the present disclosure may be used. A pellet-shaped substance may be used, which is obtained by impregnating a porous metal such as iron or steel with a composition containing the compound of the present disclosure and a liquid medium, and drying the liquid medium to impregnate the compound of the present disclosure. When a pellet-shaped substance is used, since a compound that is solid at 25°C has lower molecular mobility, deterioration of storage stability due to hydrolysis and condensation reactions is suppressed.

[0156] Examples of wet coating methods include spin coating, wipe coating, spray coating, squeegee coating, dip coating, die coating, inkjet coating, flow coating, roll coating, cast coating, Langmuir-Bludget coating, and gravure coating.

[0157] To improve the abrasion resistance of the surface treatment layer, operations to promote the reaction between the compound of this disclosure and the substrate may be performed as needed. Such operations include heating, humidification, and light irradiation. For example, heating a substrate on which a surface treatment layer has been formed in a humid atmosphere can promote reactions such as the hydrolysis of hydrolyzable groups, the reaction between hydroxyl groups on the surface of the substrate and silanol groups, and the formation of siloxane bonds by the condensation reaction of silanol groups. After surface treatment, compounds in the surface treatment layer that are not chemically bonded to other compounds or the substrate may be removed as needed. Methods of removal include, for example, pouring a solvent over the surface treatment layer or wiping it with a cloth soaked in a solvent.

[0216] [Manufacturing of Articles] The substrate was surface-treated using the above compound to obtain each article. For each example, the following dry coating method was used as the surface treatment method. Chemically strengthened glass was used as the substrate. The obtained articles were evaluated by the following method. The results are shown in Table 1. 30 g of silicon oxide was placed as a deposition source in the copper hearth inside the vacuum deposition apparatus (ULVAC KIKO "VTR-350M"). The glass substrate was placed inside the vacuum deposition apparatus, and the inside of the vacuum deposition apparatus was evaporated in 5 × 10⁻¹⁰⁻¹ -3 The system was evacuated until the pressure was below Pa. The hearth was heated to approximately 2,000°C, and silicon oxide was vacuum-deposited onto the surface of the substrate to produce a substrate with a silicon oxide layer approximately 20 nm thick. This was done using a vacuum deposition apparatus (ULVAC, product name: VTR350M) (vacuum deposition method). 0.5 g of each compound was packed into a molybdenum boat inside the vacuum deposition apparatus, and the inside of the vacuum deposition apparatus was evacuated to 1 × 10⁻⁶ -3 The pressure was reduced to below Pa. The boat containing the compound was heated at a rate of 10°C / min or less, and when the deposition rate measured by a quartz crystal film thickness gauge exceeded 1 nm / second, the shutter was opened to begin film formation on the substrate surface. When the film thickness reached approximately 50 nm, the shutter was closed to end film formation on the substrate surface with the silicon oxide layer. The substrate on which the compound or composition was deposited was heat-treated at 140°C for 30 minutes and washed with ethanol to obtain an article having a surface treatment layer on the substrate surface.

[0217] [Evaluation] <Water Repellency> Approximately 2 μL of distilled water was dropped onto the surface treatment layer of the object, and the initial water contact angle was measured using a contact angle measuring device (product name "DM-500", manufactured by Kyowa Interface Science Co., Ltd.). The average value measured at five locations on the surface treatment layer was defined as the water contact angle. The water repellency of the surface treatment layer was evaluated based on the following criteria. The 2θ method was used to calculate the water contact angle. (Evaluation Criteria) A (Excellent): Initial water contact angle is 105 degrees or higher B (Poor): Initial water contact angle is less than 105 degrees

[0218] <Abrasion Resistance Test> Using a reciprocating traverse testing machine (KNT Co., Ltd., custom-made), a flannel cloth conforming to JIS L0803:2011 was used to test the surface of surface-treated glass at a rate of 2N / 4cm². 2 After applying a load and undergoing 200 reciprocating wear cycles at a speed of 100 cycles per minute, the water contact angle was evaluated using the method described above. (Evaluation Criteria) A (Excellent): Decrease in water contact angle after wear is 5 degrees or less B (Good): Decrease in water contact angle after wear is greater than 5 degrees and less than or equal to 10 degrees C (Acceptable): Decrease in water contact angle after wear is greater than 10 degrees and less than or equal to 15 degrees D (Unacceptable): Decrease in water contact angle after wear is greater than 15 degrees

[0219] <Water Resistance> The item was cut into 1cm x 1cm squares and immersed in saturated saline solution at 20°C for 300 hours. After removal, it was washed with ethanol, dried, and the water contact angle was measured. The smaller the decrease in water repellency (water contact angle) after immersion, the smaller the decrease in performance due to water, and the better the water resistance. (Evaluation Criteria) A (Excellent): Decrease in water contact angle after immersion is 3° or less B (Acceptable): Decrease in water contact angle after immersion is more than 3° but 10° or less C (Unacceptable): Decrease in water contact angle after immersion is more than 10°

[0220] <Fingerprint Wiping Performance> A 1 kg weight equipped with a 2 cm diameter red rubber stopper to serve as the fingerprint stamp portion was prepared. Next, 70 μL of artificial fingerprint solution (manufactured by Isekyu Co., Ltd.) was dropped onto a cloth, and the fingerprint stamp was left in the solution for 1 minute. To remove excess artificial fingerprint solution from the fingerprint stamp, it was left in a new cloth for 20 seconds. After that, an article with a surface treatment layer was placed on a hot plate heated to 23°C. The fingerprint stamp was pressed onto the surface treatment layer. The article with the artificial fingerprint solution attached was placed in a sliding device (product name "HHS-2000", manufactured by Shinto Kagaku Co., Ltd.). A wiping cloth (Savina Minimax, manufactured by KB Seiren Co., Ltd.) was attached to a flat indenter with an area of ​​1 cm square using double-sided tape, and placed in the sliding device. With a load of 100 g, the artificial fingerprint solution attached to the surface treatment layer was wiped off with the wiping cloth in one direction. The haze was measured on the wiped area using a haze meter (product name "NDH7000SP", manufactured by Nippon Denshoku Co., Ltd.). (Evaluation criteria) A (Excellent): Haze value less than 0.1% B (Good): Haze value between 0.1% and less than 1% C (Poor): Haze value of 1% or more
