DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] In the present disclosure, a numerical range indicated using "~" includes the numerical values ​​before and after "~" as the minimum and maximum values, respectively. In the numerical ranges described in stages in this disclosure, the upper or lower limit value described in one numerical range may be replaced with the upper or lower limit value of another numerical range described in stages. The limit values ​​may be replaced by values ​​shown in the examples. In the present disclosure, the term "surface treatment layer" refers to a layer formed on the surface of a substrate by surface treatment. In the present disclosure, "uniformity" refers to the smoothness of the surface of the surface treatment layer. In the present disclosure, when a compound or group is represented by a specific formula (X), the compound or group represented by the formula (X) may be referred to as compound (X) or compound X, and group (X) or group X, respectively.

[0010] [Surface treatment agent] The surface treatment agent of the present disclosure contains a compound having a reactive group and 1-chloro-2,3,3-trifluoro-1-propene (HCFO-1233yd).

[0011] According to the surface treatment agent of the present disclosure, a surface treatment agent with excellent uniformity can be formed. This is believed to be because 1-chloro-2,3,3-trifluoro-1-propene (HCFO-1233yd) as a solvent has excellent compatibility with compounds having reactive groups.

[0012] Hereinafter, each component contained in the surface treatment agent of the present disclosure will be described in detail.

[0015] From the viewpoint of improving the uniformity of the surface treatment layer, it is preferable to use less HCFO-1233yd(E) having a low boiling point than HCFO-1233yd(Z) having a high boiling point. This is because HCFO-1233yd(Z) is less likely to evaporate due to its high boiling point, and the relatively high content of HCFO-1233yd(Z) makes the film formation speed appropriate, which is thought to improve the uniformity of the film. In other words, the mass ratio of the content of HCFO-1233yd(E) to the content of HCFO-1233yd(Z) is preferably less than 1, more preferably 0.80 or less, and even more preferably 0.65 or less.

In addition, a substrate having a surface treatment is preferably a substrate having a surface treatment. When the substrate is provided with a base layer described later, the adhesion to the base layer is more excellent and the abrasion resistance of the surface treatment layer is further improved.

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. If the thickness of the underlayer is equal to or greater than the lower limit, the adhesion of the underlayer to the surface treatment layer is improved, and the surface treatment layer has better abrasion resistance.

The thickness of the underlayer is measured by observing a cross section of the underlayer with a transmission electron microscope (TEM).

[0339] The underlayer can be formed by, for example, a deposition method using a deposition material or a wet coating method.

[0340] The deposition material used in the deposition method preferably contains an oxide containing silicon and a specific element.

[0342] A specific example of a deposition method using a deposition material is a vacuum deposition method, in which a deposition material is evaporated in a vacuum chamber and attached to the surface of a substrate.

The evaporation method of the deposition materials may use multiple boats, or may use a single boat containing all the deposition materials. The deposition method may be co-deposition or alternating deposition. Specifically, examples include a case where silica and a specific source are mixed in the same boat and used, a case where silica and a specific element source are placed in separate boats and co-deposited, and a case where they are placed in separate boats and alternately deposited.

The coated substrate was then heat-treated at 140°C for 30 minutes. As a result, an article having a surface treatment layer on the surface of the silicon oxide layer was obtained.

[0374] Next, the uniformity of the surface treatment layer of the obtained article was evaluated.

[0375] The arithmetic mean height Sa of the surface of the surface treatment layer was measured using an atomic force microscope (product name "AFM5500M", manufactured by Hitachi High-Tech Science Corporation). The evaluation criteria were as follows: The "arithmetic mean roughness of a surface (Sa)" is a parameter that extends Ra (arithmetic mean roughness of a line) to a surface, and represents the average of the absolute value of the difference in height of each point with respect to the average surface of the surface. The calculation method complies with ISO 25178:2010. A: Sa is 10 nm or less. B: Sa is more than 10 nm and 20 nm or less. C: Sa is greater than 20 nm.

[0376] The evaluation results are shown in Table 1. Examples 1 to 4 are working examples, and Examples 5 and 6 are comparative examples.

[0377] [Table 1]

[0378] As shown in Table 1, in Examples 1 to 4, it was found that a surface treatment layer having excellent uniformity could be formed on the substrate, which contained a compound having a reactive group and HCFO-1233yd. It was found that in Examples 1 to 3, in which the mass ratio of the content of HCFO-1233yd(E) to the content of HCFO-1233yd(Z) was less than 1, a surface treatment layer having particularly excellent uniformity could be formed.
