[1093] The oxide contained in the substrate layer can be a mixture of individual oxides of the aforementioned elements (silicon and specific elements) (e.g., a mixture of silicon oxide and oxides of specific elements), a composite oxide containing two or more of the aforementioned elements, or a mixture of individual oxides of the aforementioned elements and composite oxides.

[1097] The thickness of the substrate layer is preferably 1~100 nm, more preferably 1~50 nm, and even more preferably 2~20 nm. If the thickness of the substrate layer is above the lower limit mentioned above, the adhesion of the surface treatment layer based on the substrate layer is further improved, and the wear resistance of the surface treatment layer is more excellent. If the thickness of the substrate layer is below the upper limit mentioned above, the wear resistance of the substrate layer itself is excellent.

[1098] The thickness of the basal layer was determined by cross-sectional observation of the basal layer based on transmission electron microscopy (TEM).

[1099] The substrate layer can be formed, for example, by vapor deposition or wet coating using vapor deposition materials.

[1100] The vapor deposition material used in the vapor deposition process preferably contains oxides containing silicon and specific elements.

[1101] Specific examples of vapor deposition materials include powder, melt, sintered body, granulated body, and broken body. From an operational point of view, melt, sintered body, and granulated body are preferred.

[1102] Here, "molten body" refers to a solid obtained by melting the powder of vapor-deposited material at a high temperature and then cooling and solidifying it. "Sintered body" refers to a solid obtained by sintering the powder of vapor-deposited material; it can replace the powder of vapor-deposited material as needed, or the powder can be pressed into a molded body. "Granulated body" refers to a solid obtained by mixing the powder of vapor-deposited material with a liquid medium (such as water or organic solvent) to obtain granules, and then drying the granules.

[1103] Vaporized materials can be manufactured, for example, by the following methods.

[1104] • A method of mixing silicon oxide powder with powder of oxides of specific elements to obtain powder of vapor deposition material.

[1105] • A method for obtaining granules by mixing the powder of the above-mentioned vapor deposition material with water, and then drying the granules to obtain granulated vapor deposition material.

[1106] • A method of obtaining a sintered body by drying a mixture of silicon-containing powder (e.g., powder composed of silicon oxide, silica sand, silica gel), powder containing a specific element (e.g., powder of oxide of a specific element, carbonate, sulfate, nitrate, oxalate, hydroxide), and water, and then firing the dried mixture or a molded body formed by pressing it.

[1107] • A method of obtaining a melt by melting silicon-containing powder (e.g., powder composed of silicon oxide, silica sand, silica gel) and powder containing specific elements (e.g., powder of oxides of specific elements, carbonates, sulfates, nitrates, oxalates, hydroxides) at high temperature and then cooling and solidifying the melt.

[1108] As a specific example of a vapor deposition method using vapor deposition materials, vacuum vapor deposition can be cited. Vacuum vapor deposition is a method in which the vapor deposition material evaporates in a vacuum tank and adheres to the surface of a substrate.

[1109] The temperature during vapor deposition (for example, the temperature of the vessel for preparing the vapor deposition material when using a vacuum vapor deposition apparatus) is preferably 100 to 3000°C, and more preferably 500 to 3000°C.

[1111] When using vapor deposition materials to form the base layer, one type of vapor deposition material can be used, or two or more vapor deposition materials containing different elements can be used.

From the viewpoint that localized heating is possible, allowing even high-melting-point substances to evaporate, and that areas not irradiated by the electron beam are at low temperatures, thus eliminating concerns about reaction with the container or contamination by impurities, the electron gun method is preferred as an evaporation method for vapor-deposited materials.

[1113] Evaporation methods for depositing materials can utilize multiple boats or a single boat containing all the depositing material. Deposition methods can include co-deposition and alternating deposition. Specifically, examples include: mixing silicon dioxide and a specific source in the same boat; co-deposition of silicon dioxide and a specific element source in their respective boats; and alternating deposition in their respective boats. The deposition conditions and sequence are appropriately selected based on the composition of the substrate.

[1219] C: The average water contact angle is less than 100°

[1220] <Abrasion Resistance>

[1221] For the surface treatment layer of the article, according to JIS L0849:2013 (corresponding to ISO 105-X12:2001), a reciprocating traverse testing machine (manufactured by KNENTACORPORATION) was used to reciprocate steel wool BONSTAR (#0000) for 10,000 cycles at a pressure of 98.07 kPa and a speed of 320 cm / min. The water contact angle after the friction test was then measured. The water contact angle was measured using the same method as the initial water contact angle measured in the above evaluation of water repellency.

[1222] Abrasion resistance is evaluated based on the reduction in water contact angle caused by friction testing. The smaller the reduction in water contact angle, the better the abrasion resistance.

[1223] The evaluation criteria are as follows. A and B represent levels that are practically problem-free. The results are shown in Table 1.

[1224] The decrease in water contact angle = (initial water contact angle) - (water contact angle after friction test)

[1225] A: The reduction in water contact angle is less than 5°.

[1226] B: The decrease in water contact angle is greater than 5° and less than 10°.

[1227] C: The reduction in water contact angle exceeds 10°.

[1228] <Lightfastness>

[1229] A uniform illumination unit (Ushio Corporation) was installed on a mercury lamp (SP-9 250DB, manufactured by Ushio Electric Co., Ltd.), and the sample was placed at a distance of 17.5 cm from the lens. The light intensity in the 200–800 nm range was measured using an intensity meter (VEGA, OPHIR Corporation), and the result was 200 mW / cm². 2 In addition, the spectral irradiance of the aforementioned mercury lamp exhibits bright lines in the region below 300 nm.

[1230] Under atmospheric conditions of 20–40°C and 30–75% humidity, the surface treatment layer of the sample was irradiated with mercury lamp light for 6 hours, and the water contact angle after the light irradiation test was measured. The water contact angle was measured using the same method as the initial water contact angle measurement in the above-mentioned evaluation of water repellency.

[1231] Lightfastness is evaluated based on the decrease in water contact angle caused by light irradiation. The smaller the decrease in water contact angle, the better the lightfastness.

[1232] The evaluation criteria are as follows. A and B represent levels that are practically problem-free. The results are shown in Table 1.

[1233] The decrease in water contact angle = (initial water contact angle) - (water contact angle after light irradiation test)

[1234] A: The reduction in water contact angle is less than 5°.

[1235] B: The decrease in water contact angle is greater than 5° and less than 10°.

[1236] C: The reduction in water contact angle exceeds 10°.

[1237] [Table 1]

[1238]

[1239] As shown in Table 1, it can be seen that in Examples 1-2, 5-9 and 14, compared with Examples 3-4 and 10-13, a surface treatment layer with good wear resistance and light resistance can be formed.
