[0006] According to this disclosure, it is possible to provide an article having a surface treatment layer that has higher friction resistance. [Modes for carrying out the invention]

[0007] In this specification, "monovalent organic group" means a monovalent group containing carbon. Monovalent organic groups are not particularly limited, but may be hydrocarbon groups or derivatives thereof. A derivative of a hydrocarbon group means a group having one or more N, O, S, Si, amide, sulfonyl, siloxane, carbonyl, carbonyloxy, etc., at the terminal or molecular chain of a hydrocarbon group. When simply referred to as "organic group," it means a monovalent organic group. Furthermore, "divalent organic group" means a divalent group containing carbon. Examples of such divalent organic groups include divalent groups obtained by removing one more hydrogen atom from an organic group. Similarly, trivalent or higher organic groups mean groups obtained by removing a predetermined number of hydrogen atoms from an organic group.

[0008] As used herein, "hydrocarbon group" means a group containing carbon and hydrogen, obtained by removing a hydrogen atom from a hydrocarbon. Such hydrocarbon groups are not particularly limited, but include C 1-20 Examples of hydrocarbon groups include aliphatic hydrocarbon groups and aromatic hydrocarbon groups. The above-mentioned "aliphatic hydrocarbon group" may be linear, branched, or cyclic, and may be saturated or unsaturated. The hydrocarbon group may also contain one or more ring structures. The hydrocarbon group may be substituted with one or more substituents.

[0009] In the use herein, the substituents of the "hydrocarbon group" are not particularly limited, but may be, for example, a halogen atom, or a halogen atom, or C 1-6 Alkyl alkyl group, C 2-6 Alkenyl group, C 2-6 Alkynyl group, C 3-10 Cycloalkyl groups, C 3-10 Unsaturated cycloalkyl group, 5-10 membered heterocyclyl group, 5-10 membered unsaturated heterocyclyl group, C 6-10 Examples include one or more groups selected from aryl groups and heteroaryl groups with 5 to 10 members.

[0010] As used herein, "hydrolyzable group" means a group that can undergo hydrolysis, that is, a group that can be removed from the main skeleton of a compound by hydrolysis. Examples of hydrolyzable groups include -OR h , -OCOR h , -ON=CR h 2. -NR h 2, -NHR h , or -NCO (wherein R in these formulas) h Examples include -OR (where - represents a substituted or unsubstituted C1-C4 alkyl group), and preferably -OR h (That is, an alkoxy group). h Examples include unsubstituted alkyl groups such as methyl, ethyl, propyl, isopropyl, n-butyl, and isobutyl groups; and substituted alkyl groups such as chloromethyl groups. Among these, alkyl groups, particularly unsubstituted alkyl groups, are preferred, and methyl or ethyl groups are more preferred.

[0011] The articles of this disclosure are glass and the following formula (1): [ka] [In formula: R 1 is a linear C 11-36 It is an alkyl group, X 1 These are single bonds, or -CO-, -COO-, -NR 2 -, -CONR 2 -, -OCONR 2 -, -NR 2 -CO-NR 2 -, -O- or -S- is a divalent group, R 2 is a hydrogen atom or C 1-6 It is an alkyl group, R Si This is a monovalent group containing a Si atom to which a hydroxyl group or hydrolyzable group is bonded. It includes a surface treatment layer formed from a compound represented by [the formula shown].

[0012] The surface treatment layer included in the articles of this disclosure has both high abrasion resistance and fingerprint wiping properties. Furthermore, depending on the composition of the surface treatment agent used, the surface treatment layer may also have water repellency, oil repellency, stain resistance, waterproofing (preventing water from entering electronic components, etc.), surface slipperiness (or lubricity, for example, excellent tactile feel to the finger), and chemical resistance.

[0013] The thickness of the surface treatment layer is not particularly limited, but is preferably 15 nm or less, for example, 1 to 15 nm, 1 to 13 nm, or 1 to 10 nm.

[0014] In one embodiment, the article of the present disclosure may include an intermediate layer containing silicon oxide between the glass and the surface treatment layer. By providing such an intermediate layer, the adhesion between the glass and the surface treatment layer is improved, and the durability is improved.

[0015] In a preferred embodiment, the intermediate layer may contain alkali metal atoms in addition to silicon dioxide.

[0016] Examples of the alkali metal atoms mentioned above include lithium, sodium, and potassium. The alkali metal atom is preferably sodium.

[0017] The thickness of the intermediate layer is not particularly limited, but is preferably 1 to 200 nm, and particularly preferably 1 to 20 nm. By setting the thickness of the intermediate layer to be above the lower limit of the above range, the effect of improving adhesion by the intermediate layer becomes greater.

[0018] The alkali metal atom concentration in the intermediate layer can be measured using various surface analysis devices, such as TOF-SIMS, XPS, and XRF.

[0019] The proportion of alkali metal atoms in the total atoms of the intermediate layer can be obtained by XPS depth profiling using ion sputtering. This is done by repeatedly alternating between XPS measurement and surface etching using an ion gun built into the XPS instrument.

[0020] In the intermediate layer, the average concentration of alkali metals in the region with a depth of 1 nm or less from the surface in contact with the surface treatment layer is determined by obtaining a depth profile of alkali metal atom concentrations using TOF-SIMS (time-of-flight secondary ion mass spectrometry) depth profiling by ion sputtering, and then calculating the average value of alkali metal atom concentrations in that profile. TOF-SIMS depth profiling by ion sputtering is performed by repeatedly alternating between TOF-SIMS measurement and surface etching using an ion gun built into the TOF-SIMS instrument.

[0021] The articles of this disclosure may be optical components, but are not limited to these. Examples of optical components include: lenses such as those in eyeglasses; front protective plates, anti-reflective plates, polarizing plates, and anti-glare plates for displays such as PDPs and LCDs; touch panel sheets for devices such as mobile phones and personal digital assistants; disc surfaces for optical discs such as Blu-ray (registered trademark) discs, DVD discs, CD-Rs, and MOs; optical fibers; and display surfaces for watches.

[0022] Furthermore, the articles of this disclosure may be medical devices or medical materials. Also, articles having a surface treatment layer obtained by this disclosure may be automotive interior and exterior components. Examples of exterior components include: windows, light covers, and exterior camera covers. Examples of interior components include: instrument panel covers, navigation system touch panels, and decorative interior components.

[0260] Examples of silicon oxide precursors include silicic acid, partial condensates of silicic acid, alkali metal silicates, silane compounds having a hydrolyzable group bonded to a silicon atom, and partial hydrolyzable condensates of the silane compounds. Silicic acid and its partial condensates can be dehydrated and condensed to produce silicon oxide, while alkali metal silicates can be converted to silicic acid or its partial condensates using an acid or cation exchange resin, and the resulting silicic acid or partial condensates can be dehydrated and condensed to produce silicon oxide. Examples of hydrolyzable groups in silane compounds having a hydrolyzable group bonded to a silicon atom include alkoxy groups and chlorine atoms. The hydrolyzable group in the silane compound can be hydrolyzed to a hydroxyl group, and the resulting silanol compound can be dehydrated and condensed to produce silicon oxide. Examples of silane compounds having a hydrolyzable group bonded to a silicon atom include alkoxysilanes such as tetraalkoxysilanes and alkyltrialkoxysilanes, and tetrachlorosilanes.

[0261] Examples of alkali metal sources include alkali metal hydroxides and water-soluble alkali metal salts. Examples of water-soluble alkali metal salts include alkali metal carbonates, alkali metal bicarbonates, alkali metal hydrochlorides, and alkali metal nitrates. Alkali metal hydroxides and alkali metal carbonates are preferred as alkali metal sources.

[0262] Furthermore, alkali metal silicates can be used as silicon oxide precursors and alkali metal sources. Alkali metal silicates can be converted to silicon oxide via silicic acid, but a small amount of alkali metal may remain in the silicon oxide produced during this process. Therefore, by adjusting the amount of residual alkali metal atoms, silicon oxide containing a predetermined amount of alkali metal atoms can be obtained.
