[1046] a', b', c' and d' respectively represent the number of four repeating units of perfluoropolyether constituting the main skeleton of the polymer, and are independently integers of 0 to 300. The sum of a', b', c' and d' is at least 1, preferably 1 to 300, and more preferably 20 to 300. The order of existence of the repeating units marked with subscripts a', b', c' or d' and enclosed in parentheses in the formula is arbitrary. Among these repeating units, -(OC4F8)- can be -(OCF2CF2CF2CF2)-,

[1051] R 5 -(OCF2CF2CF2) b” -Rf 6 …(3a)

[1052] R 5 -(OCF2CF2CF2CF2) a” -(OCF2CF2CF2) b” -(OCF2CF2) c” -(OCF2) d” -Rf 6 …(3b)

[1053] In these formulas, Rf 5 and Rf 6 As described above; in formula (3a), b" is an integer greater than 1 and less than 100; in formula (3b), a" and b" are each independently an integer greater than 0 and less than 30, and c" and d" are each independently an integer greater than 1 and less than 300.

In one embodiment, the surface treatment agent of the present invention does not substantially contain fluorinated oil. Substantially containing no fluorinated oil means that it does not contain any fluorinated oil at all, or may contain a very small amount of fluorinated oil.

[1057] In one embodiment, the average molecular weight of the fluorinated oil can be greater than the average molecular weight of the silane compound containing a fluorinated polyether group. By designing the average molecular weight in this way, better friction durability and surface sliding properties can be obtained, especially when the surface treatment layer is formed by vacuum deposition.

[1058] In one embodiment, the average molecular weight of the fluorinated oil can be made smaller than the average molecular weight of the silane compound containing the fluorinated polyether group. By designing the average molecular weight in this way, the transparency of the surface treatment layer obtained by the compound can be suppressed from decreasing, and a cured product with high friction durability and high surface slip can be formed.

[1069] Hereinafter, the article of the present invention will be described.

[1070] The article of the present invention comprises a substrate and a layer (surface treatment layer) formed on the surface of the substrate using the surface treatment agent of the present invention.

[1071] The substrate that can be used in the present invention can be composed of, for example, glass, resin (natural or synthetic resin, which can be, for example, a general plastic material), metal, ceramic, semiconductor (silicon, germanium, etc.), fiber (textile, non-woven fabric, etc.), fur, leather, wood, ceramics, stone, etc., building parts, etc., sanitary products, and any other appropriate material.

[1072] For example, when the article to be manufactured is an optical component, the material constituting the surface of the substrate can be a material for optical components, such as glass or transparent plastic. In addition, when the article to be manufactured is an optical component, a certain layer (or film), such as a hard coating or an anti-reflection layer, can also be formed on the surface (outermost layer) of the substrate.

When a multi-layer anti-reflection layer is used, it is preferred that SiO2 and / or SiO be used in the outermost layer. When the object to be manufactured is an optical glass component for a touch screen, a portion of the surface of the substrate (glass) may have a transparent electrode, such as a thin film of indium tin oxide (ITO) or indium zinc oxide. In addition, the substrate may have an insulating layer, an adhesive layer, a protective layer, a decorative frame layer (I-CON), an atomized film layer, a hard coating layer, a polarizing film, a phase difference film, and a liquid crystal display module, etc., depending on its specific style.

As the material, glass can be cited, and metals (especially base metals), ceramics, semiconductors, etc. with natural oxide films or thermal oxide films formed on the surface can also be cited. Alternatively, as in the case of resins, etc., although there are insufficient hydroxyl groups, or when there are no hydroxyl groups originally, certain pretreatments can be applied to the substrate to introduce hydroxyl groups on the surface of the substrate or increase them. As examples of the pretreatment, plasma treatment (such as corona discharge) or ion beam irradiation can be cited. Plasma treatment is also suitable for introducing hydroxyl groups on the surface of the substrate or increasing hydroxyl groups, and cleaning the surface of the substrate (removing foreign matter, etc.). In addition, as another example of the pretreatment, it can be cited: using the LB method (Langmuir-Blodgett method, Langmuir-Blodgett method) or chemical adsorption method, etc., a film of an interface adsorbent having a carbon-carbon unsaturated bond group is formed in the form of a monomolecular film on the surface of the substrate in advance, and then, the unsaturated bond is disconnected in an atmosphere containing oxygen or nitrogen.

For simplicity, when using a wet covering method, the catalyst can be added to the diluent of the surface treatment agent of the present invention after the surface treatment agent of the present invention is diluted with a solvent and before it is applied to the surface of the substrate. When using a dry covering method, the surface treatment agent of the present invention to which the catalyst is added can be directly subjected to vapor deposition (usually vacuum deposition), or a granular material in which the surface treatment agent of the present invention to which the catalyst is added is impregnated in a metal porous body such as iron or copper is subjected to vapor deposition (usually vacuum deposition).

[1141] (Rubber friction durability test)

[1142] For the surface treatment layer formed on the substrate surface using the above-mentioned Examples 1 to 21 and Comparative Examples 1 to 6, the static contact angle (degrees) of water at 5 locations was measured, and the average value (degrees) was taken as the value of the initial contact angle (degrees) (friction number 0).
