[1052] The thickness of the surface treatment layer is preferably 1–100 nm, more preferably 1–50 nm. If the thickness of the surface treatment layer is 1 nm or more, the effect based on the surface treatment can be easily and fully obtained.

The substrate layer may contain two or more Group 15 elements.

[1066] As specific elements included in the base layer, elements from Group 1, Group 2, and Group 13 are preferred because the surface treatment layer has better wear resistance, with elements from Group 1 and Group 2 being more preferred, and elements from Group 1 being even more preferred.

[1067] As a specific element, it can contain only one type of element or two or more types of elements.

[1072] 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 or below 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 or below the upper limit mentioned above, the wear resistance of the substrate layer itself is excellent.

[1073] The thickness of the basal layer was determined by cross-sectional observation of the basal layer based on transmission electron microscopy (TEM).

[1074] The substrate layer can be formed, for example, by vapor deposition or wet coating using vapor deposition materials.

[1075] The vapor deposition material used in the vapor deposition process preferably contains oxides containing silicon and specific elements.

"Sintered body" refers to a solid obtained by sintering the powder of vapor-deposited material. Depending on the needs, it can also replace the powder of vapor-deposited material by pressing it into a molded form. "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.

[1078] Vaporized materials can be manufactured, for example, by the following methods.

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.

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.

[1184] Compound 1 and Compound 2, as shown in Table 1, were mixed at the mass ratios shown in Table 1, and heptane was added as a liquid medium to obtain a surface treatment agent with a solid content of 20% by mass.

[1185] The substrate was surface-treated using a surface treatment agent. Dry coating was used as the surface treatment method.

[1186] Chemically strengthened glass is used as the substrate.

[1187] 30g of silicon dioxide was placed as the deposition source in a copper furnace cylinder within a vacuum evaporation apparatus (ULVAC KIKO, Inc., "VTR-350M"). A glass substrate was placed inside the vacuum evaporation apparatus, and the air inside the apparatus was evaporated to a pressure of 5×10⁻⁶. -3 Pressure below Pa. The furnace cylinder is heated to about 2,000°C, and silicon oxide is vacuum-deposited on the surface of the substrate to produce a substrate with a silicon oxide layer having a thickness of about 20 nm.

[1188] 0.5g of each surface treatment agent was added to the molybdenum boat dish inside the vacuum evaporation apparatus, and the vacuum evaporation apparatus was evaporated to a pressure of 1×10⁻⁶. -3 Pa below. The boat containing the surface treatment agent is heated at a heating rate of less than 10°C / min. When the evaporation rate based on the quartz oscillating film thickness gauge exceeds 1 nm / s, the baffle is opened to begin film deposition on the surface of the substrate.

[1189] The baffle is closed when the film thickness reaches approximately 50 nm, ending the film formation process on the surface of the substrate with the silicon oxide layer. The substrate with the deposited compound or composition is then heated at 140°C for 30 minutes and cleaned with ethanol to obtain an article with a surface treatment layer on the surface of the substrate.

[1190] The water repellency, abrasion resistance, and fingerprint removability of items obtained by dry coating were evaluated. The evaluation methods are described below.

[1191] Water repellency

[1192] Approximately 2 μL of distilled water was dropped onto the surface treatment layer of the item, and the initial water contact angle was measured using a contact angle measuring device (product name "DM-500", Kyowa Interface Science Co., Ltd.). The average value of the measurements taken at 5 points on the surface treatment layer was taken as the water contact angle. It should be noted that the water contact angle was calculated using the 2θ method. The evaluation criteria are as follows. AA, A, and B represent levels that are practically without problems.

[1193] AA: The initial water contact angle is greater than 105°.

[1194] A: The initial water contact angle is greater than 100° and less than 105°.

[1195] B: The initial water contact angle is greater than 95° and less than 100°.

[1196] C: The initial water contact angle is less than 95°.

[1197] <Abrasion Resistance 1>

[1198] For the surface treatment layer of the item, according to JIS L0849:2013 (corresponding to ISO: 105-X12:2001), a reciprocating traverse testing machine (manufactured by KNT Corporation) was used. Steel wool Bonstar (#0000) was subjected to 100 reciprocating 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 method for measuring the water contact angle after the friction test was the same as the method for measuring the initial water contact angle in the above-mentioned evaluation method for liquid repellency. First, after 100 reciprocating cycles, if the obtained water contact angle value was less than 90°, the friction test was ended, and the number of cycles at the end was recorded. If the obtained water contact angle value was greater than 90°, the friction test was then performed. This operation was repeated until the maximum number of cycles was 10,000. The evaluation criteria are as follows. A and B represent levels that are practically problem-free.

[1199] A: The number of friction cycles is over 2,000.

[1200] B: The number of friction cycles is more than 1,000 but less than 2,000.

[1201] C: The number of friction cycles is less than 1,000.

[1202] <Abrasion Resistance 2>

[1203] For the surface treatment layer of the item, according to JIS L0849:2013 (corresponding to ISO: 105-X12:2001), a reciprocating traverse testing machine (manufactured by KNT Corporation) was used. Steel wool Bonstar (#0000) was subjected to 100 reciprocating 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 method for measuring the water contact angle after the friction test was the same as the method for measuring the initial water contact angle in the above-mentioned evaluation method for liquid repellency. First, after 100 reciprocating cycles, if the obtained water contact angle value was less than 100°, the friction test was ended, and the number of cycles at the end was recorded. If the obtained water contact angle value was greater than 100°, the friction test was continued. This operation was repeated until the maximum number of cycles was 10,000. The evaluation criteria are as follows. A and B represent levels that are practically problem-free.

[1204] A: The number of friction cycles is over 400.

[1205] B: The number of friction cycles is more than 200 but less than 400.

[1206] C: The number of friction cycles is less than 200.

[1207] Fingerprint Removal

[1208] Prepare a 1kg weight with a 2cm diameter red rubber stopper to form the fingerprint impression. Next, add 70μL of artificial fingerprint liquid (manufactured by Ise-hisa Co., Ltd.) to a wiping cloth and allow the fingerprint to adhere in the artificial fingerprint liquid for 1 minute. To remove excess artificial fingerprint liquid adhering to the fingerprint, allow the fingerprint to adhere to a new wiping cloth for 20 seconds. Then, place the item with a surface treatment layer on a hot plate with the temperature set to 23°C. Imprint the fingerprint onto the surface treatment layer.

[1209] An item coated with artificial fingerprint liquid was placed on a sliding device (product name "HHS-2000", manufactured by Shinto Science Co., Ltd.). A flat pressure head with a 1cm square area was attached to a wiping cloth (KB Seiren Co., Ltd., Savina Minnimax) using double-sided tape and placed on the sliding device. The surface treatment layer was wiped with the wiping cloth in one direction with a load of 100g to remove the coated artificial fingerprint liquid. The haze of the wiped area was measured using a haze meter (product name "NDH7000SP", manufactured by Nippon Denshoku Co., Ltd.). The evaluation criteria are as follows.

[1210] A: Haze value is less than 1%.

[1211] B: Haze value is above 1% and less than 5%.

[1212] C: Haze value is above 5%.

[1213] The evaluation results are shown in Table 1.

[1214] In Table 1, Y in requirement (1) and requirement (2) respectively refers to meeting requirement (1) and requirement (2). In addition, "-" means that the first compound or the second compound is not present. In addition, "-" for wear resistance 2 indicates that it has not been implemented.

[1215] [Table 1]

[1216]

[1217] As shown in Table 1, Examples 1-4 and Examples 8-13 contain both Compound 1 and Compound 2, satisfying requirements (1) and (2), thus exhibiting excellent water repellency and abrasion resistance. Comparing Examples 1 and 3, Example 1 demonstrates superior fingerprint removal performance. Comparing Examples 2 and 4, Example 2 shows superior fingerprint removal performance.
