Problems solved by technology

Yet this antifouling composition, because the layer that is made up of inorganic compound such as silicon dioxide will obtain adhesion through the alkoxysilane that this composition contains, when there is no inorganic compound layer on the substrate surface, even The antifouling property can be obtained temporarily, but there is a problem that the long-term antifouling property cannot be exhibited
Moreover, this antifouling composition is only for the purpose of antifouling, does not have mechanical strength, and is prone to scratches on the surface.
Therefore, when the surface of the base material must have mechanical strength such as wear resistance, the surface of the base material must be provided with a hard coat layer, and there is a problem that the process becomes complicated.

example 1

[0267] In a 300mL four-necked flask equipped with a stirrer and a condenser, add 80g of polymerizable monomer (A-1), 1.0g of water and oil repellent (B-1), 4.0g of active energy ray polymerization initiator (C- 1) 1.0 g of hydroquinone monomethyl ether as a thermal polymerization inhibitor and 65.0 g of butyl acetate (AcBt) as an organic solvent were stirred for 1 hour at room temperature and protected from light to make them homogeneous. Then, while stirring, 75.0 g of colloidal silicon dioxide (D-1) was slowly added, and then stirred at room temperature and protected from light for 1 hour to make it homogeneous.

[0268] Then, 65.0 g of dibutyl ether (DBE) was added as an organic solvent, and the mixture was stirred at room temperature and protected from light for 1 hour to obtain a coating composition (Q1). Then spin-coat (2000rpm × 10 seconds) on the surface of the substrate to cover the composition (Q1), dry it in a hot air circulation oven at 90°C for 1 minute, and then ...

[0273] Then, 65.0 g of dibutyl ether (DBE) was added as an organic solvent, stirred at room temperature and protected from light for 1 hour, and the composition for coating (Q10) was obtained. Then (Q10) is spin-coated (2000rpm × 10 seconds) on the surface of the substrate, dried in a hot air circulation oven at 90°C for 1 minute, and then sprayed with a high-pressure mercury lamp (light intensity: 1200mJ / cm 2 ...
