[0331] In one embodiment, the surface treatment of the present disclosure is a dry coating method, preferably vacuum coating.

[0332] In one embodiment, the surface treatment agent of the present disclosure is for use in a wet coating method, preferably dip coating.

[0333] The surface treatment agent of the present disclosure can be impregnated into a porous material, such as a porous ceramic material or a metal fiber, such as steel wool, and formed into a pellet. The pellet can be used, for example, for vacuum deposition.

[0334] The articles of the present disclosure are described below.

[0335] The article of the present disclosure includes a substrate and a layer (surface treatment layer) formed on the surface of the substrate from the surface treatment agent of the present disclosure.

[0336] Substrates that can be used in the present disclosure may be made of any suitable material, for example, glass, resin (which may be a natural or synthetic resin, for example a general plastic material), metal, ceramics, semiconductors (silicon, germanium, etc.), fibers (woven fabrics, nonwoven fabrics, etc.), fur, leather, wood, ceramics, stone, etc., building materials, etc., sanitary products, etc.

[0337] For example, when the article to be manufactured is an optical member, the material constituting the surface of the substrate may be a material for optical members, such as glass or transparent plastic. When the article to be manufactured is an optical member, the surface (outermost layer) of the substrate may have some layer (or film), such as a hard coat layer or an anti-reflection layer. The anti-reflection layer may be either a single-layer anti-reflection layer or a multi-layer anti-reflection layer. Examples of inorganic substances that can be used for the anti-reflection layer include SiO2, SiO, ZrO2, TiO2, TiO, Ti2O3, Ti2O5, Al2O3, Ta2O5, Ta3O5, Nb2O5, HfO2, Si3N4, CeO2, MgO, Y2O3, SnO2, MgF2, and WO3. These inorganic substances may be used alone or in combination of two or more of them (for example, as a mixture). When a multi-layer anti-reflection layer is used, it is preferable to use SiO2 and / or SiO for the outermost layer. When the product to be manufactured is an optical glass part for a touch panel, a transparent electrode, for example, a thin film using indium tin oxide (ITO) or indium zinc oxide, may be provided on a part of the surface of the substrate (glass). In addition, the substrate may have an insulating layer, an adhesive layer, a protective layer, a decorative frame layer (I-CON), an atomizing film layer, a hard coating film layer, a polarizing film, a phase difference film, a liquid crystal display module, etc., depending on the specific specifications.

Examples of such materials include glass, metals (particularly base metals), ceramics, semiconductors, etc., on whose surfaces natural oxide films or thermal oxide films are formed. Alternatively, in cases where the substrate has insufficient hydroxyl groups, such as resins, or where the substrate does not originally have hydroxyl groups, the substrate may be subjected to some pretreatment to introduce or increase the number of hydroxyl groups on the substrate surface. Examples of such pretreatment include plasma treatment (e.g., corona discharge) and ion beam irradiation. Plasma treatment can introduce or increase hydroxyl groups on the substrate surface, and can also be suitably used to clean the substrate surface (remove foreign matter, etc.). Another example of such pretreatment is a method in which an interface adsorbent having a carbon-carbon unsaturated bond group is formed in advance in the form of a monomolecular film on the substrate surface by the LB method (Langmuir-Blodgett method) or chemical adsorption method, and then the unsaturated bond is cleaved in an atmosphere containing oxygen, nitrogen, etc.

[0342] The article of the present disclosure can be produced by forming a layer of the surface treatment agent of the present disclosure on the surface of the substrate, and then post-treating this layer as necessary, thereby forming a layer from the surface treatment agent of the present disclosure.

[0343] The layer formation of the surface treatment agent of the present disclosure can be carried out by applying the surface treatment agent to the surface of the substrate so as to coat the surface. The coating method is not particularly limited. For example, a wet coating method and a dry coating method can be used.
