[0163] When used in this specification, "monovalent organic group" refers to a monovalent group containing carbon. There is no particular limitation on the monovalent organic group, and it can be a hydrocarbon group or a derivative thereof. A derivative of a hydrocarbon group refers to a group having one or more N, O, S, Si, amide, sulfonyl, silyl, carbonyl, carbonyl, carbonyloxy, etc. at the end of the hydrocarbon group or in the molecular chain. In addition, when it is simply expressed as an "organic group", it means a monovalent organic group. In addition, a "divalent organic group" refers to a divalent group containing carbon. In addition, as such a divalent organic group, for example, a divalent group obtained by removing a hydrogen atom from an organic group can be cited. A trivalent or higher organic group also refers to a group obtained by removing a set number of hydrogen atoms from an organic group.

[0164] In the context of this specification, the term "hydrocarbon group" refers to a group containing carbon and hydrogen, wherein hydrogen atoms are removed from hydrocarbons. Examples of such a hydrocarbon group include, but are not particularly limited to, C 1-20The hydrocarbon group may be a hydrocarbon group such as an aliphatic hydrocarbon group, an aromatic hydrocarbon group, etc. The above-mentioned "aliphatic hydrocarbon group" may be any of a straight chain, a branched chain or a ring, and may be any of a saturated or unsaturated hydrocarbon group. In addition, the hydrocarbon group may also include one or more cyclic structures. The hydrocarbon group may be substituted by one or more substituents.

[0165] In the present specification, examples of the substituent of the "hydrocarbon group" include, but are not particularly limited to, halogen atoms, C 1-6 Alkyl, C 2-6 Alkenyl, C 2-6 Alkynyl, C 3-10 Cycloalkyl, C 3-10 unsaturated cycloalkyl, 5- to 10-membered heterocyclic group, 5- to 10-membered unsaturated heterocyclic group, C 6-10 One or more of aryl and 5- to 10-membered heteroaryl.

[0166] When used in this specification, "hydrolyzable group" refers to a group that can undergo a hydrolysis reaction, that is, a group that can be separated from the main skeleton of a compound by a hydrolysis reaction. Examples of hydrolyzable groups include -OR h , -OCOR h 、-O-N=CR h 2. -NR h 2. -NHR h or -NCO (in these formulas, R h represents a substituted or unsubstituted alkyl group having 1 to 4 carbon atoms), etc., preferably -OR h (i.e. alkoxy). h Examples of include non-substituted alkyl groups such as methyl, ethyl, propyl, isopropyl, n-butyl, and isobutyl; and substituted alkyl groups such as chloromethyl.

[0492] In one embodiment, the hydrolyzable group may be the same as the hydrolyzable group contained in the silane compound. By making the hydrolyzable group in the transition metal compound and the group in the silane compound the same, even if the hydrolyzable groups are mutually exchanged, the influence thereof can be reduced.

[0493] In another embodiment, the hydrolyzable group may be different from the hydrolyzable group contained in the silane compound. By making the hydrolyzable groups in the silane compound and the transition metal compound different, the reactivity of the hydrolysis can be controlled.

The catalyst may preferably be contained in an amount of 0.02% by mass or more relative to the entire surface treatment agent, and more preferably may be contained in an amount of 0.04% by mass or more relative to the entire surface treatment agent. The catalyst may be contained, for example, in an amount of 10% by mass or less relative to the entire surface treatment agent, and particularly may be contained in an amount of 1% by mass or less relative to the entire surface treatment agent. The surface treatment agent may contribute to the formation of a surface treatment layer having better durability by containing the catalyst in the above concentration.

[0498] The catalyst promotes the hydrolysis and dehydration condensation of the silane compound of the present invention and promotes the formation of the layer formed by the above-mentioned surface treatment agent.

[0499] Examples of other components other than the above components include tetraethoxysilane, methyltrimethoxysilane, 3-aminopropyltrimethoxysilane, 3-glycidyloxypropyltrimethoxysilane, and methyltriacetoxysilane.

[0505] The layer formation of the surface treatment agent can be carried out by applying the surface treatment agent to the surface of the substrate in a manner that covers the surface of the substrate. The coating method is not particularly limited. For example, a wet coating method and a dry coating method can be used.

[0506] Examples of wet coating methods include dip coating, spin coating, flow coating, spray coating, roll coating, gravure coating, wipe coating, blade coating, die coating, inkjet, cast film, Langmuir-Blodgett (LB) method, and the like.

[0510] When dry coating is used, the surface treatment agent of the present invention may be directly applied to the dry coating method, or may be diluted with the above-mentioned solvent and then applied to the dry coating method.

[0511] The layer formation of the surface treatment agent is preferably implemented in a state where the surface treatment agent of the present invention and the catalyst for hydrolysis and dehydration condensation coexist in the layer. A simple method may also be to dilute the surface treatment agent of the present invention with a solvent in the case of a wet coating method, and then add a catalyst to the dilution of the surface treatment agent of the present invention before applying it to the substrate surface. In the case of a dry coating method, the surface treatment agent of the present invention to which the catalyst has been added can be directly subjected to vapor deposition (usually vacuum deposition), or a granular material impregnated with the surface treatment agent of the present invention to which the catalyst has been added in a porous metal body such as iron or copper can be subjected to vapor deposition (usually vacuum deposition).

As acid catalyst, for example acetic acid, formic acid, trifluoroacetic acid, hydrochloric acid, nitric acid, sulfuric acid, phosphoric acid, sulfonic acid, methanesulfonic acid, p-toluenesulfonic acid etc. can be used. As base catalyst, for example organic amines such as ammonia, sodium hydroxide, potassium hydroxide, triethylamine and diethylamine etc. can be used. Transition metal, aliphatic amine compound and aromatic amine compound can enumerate the same compound as above.

[0513] The intermediate layer containing silicon oxide can be formed by applying a silicon oxide precursor to the substrate surface. In the case where the intermediate layer contains alkali metal atoms, the intermediate layer can be formed by applying a composition containing a silicon oxide precursor and an alkali metal source to the substrate surface.

[0514] As the above-mentioned silicon oxide precursor, silicic acid, partial condensates of silicic acid, alkali metal silicates, silane compounds having hydrolyzable groups bonded to silicon atoms, partial hydrolysis condensates of the silane compounds, etc. can be cited. Silicic acid and its partial condensates can be dehydrated and condensed to form silicon oxide, and alkali metal silicates can be made into silicic acid or its partial condensates using acids or cation exchange resins, and the generated silicic acid or its partial condensates are dehydrated and condensed to form silicon oxide. As the hydrolyzable groups in the silane compounds having hydrolyzable groups bonded to silicon atoms, alkoxy groups, chlorine atoms, etc. can be cited. The hydrolyzable groups of the silane compounds can be hydrolyzed to obtain hydroxyl groups, and the generated silanol compounds are dehydrated and condensed to obtain silicon oxide. As the silane compounds having hydrolyzable groups bonded to silicon atoms, alkoxysilanes such as tetraalkoxysilane and alkyltrialkoxysilane, and tetrachlorosilane, etc. can be cited.

[0515] As the above-mentioned alkali metal source, there can be mentioned alkali metal hydroxides, water-soluble alkali metal salts, etc. As the water-soluble alkali metal salts, there can be mentioned alkali metal carbonates, alkali metal hydrogen carbonates, alkali metal hydrochlorides, alkali metal nitrates, etc. As the alkali metal source, alkali metal hydroxides and alkali metal carbonates are preferred.

[0516] In addition, alkali metal silicates can be used as silicon oxide precursors and alkali metal sources. Alkali metal silicates can be made into silicon oxide through silicic acid, but at this time a small amount of alkali metal will remain in the generated silicon oxide. Therefore, by adjusting the amount of residual alkali metal atoms, silicon oxide containing a specified amount of alkali metal atoms can be obtained.

[0517] The article of the present invention has been described in detail above. However, it should be noted that the article of the present invention is not limited to the article described above.
