Embodiment

[0206] The present invention will be described in more detail through examples below, but the present invention is not limited by these examples.

[0207] [Abbreviations used in Examples]

[0208] The meanings of the abbreviations used in Examples and the like are as follows.

[0209] TEOS: Tetraethoxysilane

[0210] C18: Octadecyltriethoxysilane

[0211] MPS: γ-Mercaptopropyltrimethoxysilane

[0212] GPS: γ-Glycidoxypropyltrimethoxysilane

[0213] UPS: γ-ureidopropyltriethoxysilane

[0214] APS: γ-Aminopropyltriethoxysilane

[0215] ACPS: γ-Acryloyloxypropyltrimethoxysilane

[0216] MPMS: γ-methacryloxypropyltrimethoxysilane

[0217] MTES: Methyltriethoxysilane

[0218] TIPT: titanium tetraisopropoxide

[0219] AN: aluminum nitrate nonahydrate

[0220] EG: ethylene glycol

[0221] HG: 2-methyl-2,4-pentanediol (alias: hexanediol)

[0222] BCS: 2-butoxyethanol (another name: butyl cellosolve)

[0223] IPA: 2-propanol

Synthetic example 1

[0224] (Synthesis of Coating Composition K1)

[0225] 12.7 g of AN and 3.0 g of water were added to a 200 mL flask, and stirred to dissolve AN. EG13.6g, HG38.8g, BCS36.8g, TEOS21.7g, GPS10.6g were added thereto, and stirred at room temperature for 30 minutes to obtain A1 liquid.

[0226] 4.7 g of TIPT as a titanium alkoxide was placed in a 300-mL capacity flask, 58.2 g of HG was added thereto, and stirred at room temperature for 30 minutes to obtain A2 liquid.

[0227] Next, the above liquids A1 and A2 were mixed and stirred at room temperature for 30 minutes. Coating composition K1 was thus obtained.

Synthetic example 2

[0228] (Synthesis of Coating Composition K2)

[0229] 12.7 g of AN and 3.0 g of water were added to a 200 mL flask, and stirred to dissolve AN. EG13.7g, HG39.2g, BCS37.3g, TEOS21.7g, MPS8.8g were added thereto, and stirred at room temperature for 30 minutes to obtain B1 liquid.

[0230] 4.7 g of TIPT as a titanium alkoxide was placed in a 300 mL capacity flask, 58.9 g of HG was added thereto, and stirred at room temperature for 30 minutes to obtain a B2 liquid.

[0231] Next, the above liquid B1 and liquid B2 were mixed and stirred at room temperature for 30 minutes. Coating composition K2 was thus obtained.

Description

technical field [0001] The present invention relates to a coating composition for a touch panel, a coating film formed from the coating composition, and a touch panel having the coating film. Background technique [0002] Conventionally, inorganic coatings have been formed on the surfaces of substrates such as glass, ceramics, metals, and plastics for various purposes. By forming an inorganic film on the surface of a substrate, electrical properties, optical properties, chemical properties, mechanical properties, and the like can be imparted to the substrate. Therefore, these inorganic coatings are put into practical use as conductive films, insulating films, selective light transmission or absorption films, alkali metal elution prevention films, chemical-resistant films, hard coat films, and the like. [0003] As a method of forming such an inorganic film, a vapor phase method such as CVD (Chemical Vapor Deposition), PVD (Physical Vapor Deposition), sputtering, or a liquid...
