Furthermore, when a base layer described below is provided on the surface-treated substrate, it has better adhesion to the base layer and further improved abrasion resistance of the surface treatment layer.

The underlayer may contain two or more Group 2 elements.

[0217] The Group 4 elements of the periodic table (hereinafter also referred to as "Group 4 elements") refer to titanium, zirconium, and hafnium.

The underlayer may contain two or more types of Group 4 elements.

[0218] The Group 5 elements of the periodic table (hereinafter also referred to as "Group 5 elements") refer to vanadium, niobium, and tantalum.

The underlayer may contain two or more Group 13 elements.

[0220] The Group 15 elements of the periodic table (hereinafter also referred to as "Group 15 elements") refer to nitrogen, phosphorus, arsenic, antimony, and bismuth. As the Group 15 elements, phosphorus, antimony, and bismuth are preferred, and phosphorus and bismuth are more preferred, from the viewpoint of enabling a surface treatment layer to be formed more uniformly on the underlayer without defects, or from the viewpoint of further suppressing variation in the composition of the underlayer between samples. The underlayer may contain two or more Group 15 elements.

[0221] As the specific element contained in the underlayer, Group 1 elements, Group 2 elements, and Group 13 elements are preferred because they provide better abrasion resistance to the surface treatment layer, and Group 1 elements and Group 2 elements are more preferred, with Group 1 elements being even more preferred. The specific element may contain only one type of element or two or more types of elements.

[0222] The oxide contained in the underlayer may be a mixture of oxides of the above elements (silicon and the specific element) alone (for example, a mixture of silicon oxide and an oxide of the specific element), a composite oxide containing two or more of the above elements, or a mixture of an oxide of the above elements alone and a composite oxide.

[0223] From the viewpoint of achieving superior abrasion resistance of the surface treatment layer, the ratio of the total molar concentration of the specific elements in the underlayer to the molar concentration of silicon in the underlayer (specific elements / silicon) is preferably 0.02 to 2.90, more preferably 0.10 to 2.00, and even more preferably 0.20 to 1.80.

The thickness of the underlayer is preferably 1 to 100 nm, more preferably 1 to 50 nm, and even more preferably 2 to 20 nm. When the thickness of the underlayer is equal to or greater than the above lower limit, the adhesion of the underlayer to the surface treatment layer is further improved, and the surface treatment layer has better abrasion resistance. When the thickness of the underlayer is equal to or less than the above upper limit, the underlayer itself has excellent abrasion resistance. The thickness of the underlayer is measured by observing the cross section of the underlayer using a transmission electron microscope (TEM).

[0225] The underlayer can be formed by, for example, a vapor deposition method using a vapor deposition material or a wet coating method.

If necessary, a molded body may be used by press-molding the powder instead of the powder of the deposition material. The granule refers to a solid obtained by kneading the powder of the deposition material with a liquid medium (e.g., water, organic solvent) to obtain particles, and then drying the particles.

A method of kneading the vapor deposition material powder with water to obtain particles, and then drying the particles to obtain granules of the vapor deposition material. A method of mixing a powder containing silicon (e.g., silicon oxide powder, silica sand, silica gel), a powder containing a specific element (e.g., oxide powder, carbonate, sulfate, nitrate, oxalate, hydroxide of the specific element), and water, drying the mixture, and then firing the dried mixture or a compact obtained by pressing the dried mixture to obtain a sintered body. A method of melting a powder containing silicon (e.g., silicon oxide powder, silica sand, silica gel) and a powder containing a specific element (e.g., oxide powder, carbonate, sulfate, nitrate, oxalate, hydroxide of the specific element) at a high temperature, and then cooling and solidifying the melt to obtain a melt.

[0228] A specific example of a vapor deposition method using a vapor deposition material is a vacuum vapor deposition method. The vacuum vapor deposition method is a method in which a vapor deposition material is evaporated in a vacuum chamber and attached to the surface of a substrate. The temperature during vapor deposition (for example, the temperature of the boat in which the vapor deposition material is placed when a vacuum vapor deposition apparatus is used) is preferably 100 to 3,000°C, and more preferably 500 to 3,000°C. The pressure during vapor deposition (for example, the pressure in the chamber in which the vapor deposition material is placed when a vacuum vapor deposition apparatus is used) is preferably 1 Pa or less, and more preferably 0.1 Pa or less. When forming an underlayer using a vapor deposition material, one vapor deposition material may be used, or two or more vapor deposition materials containing different elements may be used.

[0229] Specific examples of evaporation methods for the deposition material include a resistance heating method, in which the deposition material is melted and evaporated on a resistance heating boat made of a high-melting-point metal, and an electron gun method, in which the deposition material is irradiated with an electron beam to directly heat the deposition material, melting and evaporating the surface. The electron gun method is preferred as an evaporation method for the deposition material because it can evaporate high-melting-point substances due to its ability to locally heat the material, and because areas not irradiated by the electron beam are at low temperatures, eliminating the risk of reaction with the container or the inclusion of impurities. The evaporation method for the deposition material may use multiple boats, or all of the deposition materials may be placed in a single boat. The deposition method may be co-evaporation or alternating deposition. Specific examples include mixing silica and a specific source in the same boat, co-evaporating silica and a specific element source in separate boats, or similarly placing them in separate boats and alternately depositing them. The deposition conditions, order, etc., are appropriately selected depending on the composition of the underlayer.

The smaller the decrease in water repellency (water contact angle) after friction, the smaller the decrease in performance due to friction, and the more excellent the abrasion resistance. The evaluation criteria are as follows: Decrease in water contact angle = (initial water contact angle) - (water contact angle after friction) A: The decrease in water contact angle after 10,000 reciprocating cycles is 3° or less B: The decrease in water contact angle after 10,000 reciprocating cycles is more than 3° and less than 5° C: The decrease in water contact angle after 10,000 reciprocating cycles is more than 5°

The smaller the decrease in water contact angle after the accelerated light resistance test, the smaller the decrease in performance due to light, and the more excellent the light resistance of the surface treatment layer. The evaluation criteria are as follows: Decrease in water contact angle = (initial water contact angle) - (water contact angle after accelerated light resistance test) A: Decrease in water contact angle after accelerated light resistance test is 3° or less B: Decrease in water contact angle after accelerated light resistance test is more than 3° and 5° or less C: Decrease in water contact angle after accelerated light resistance test is more than 5°
