Examples of conventional treatments include spraying, coating, and printing. etc. can be exemplified. On this occasion,
In the case of spray painting, apply an ultra-thin H layer antifouling layer (8
) is formed, and it is thought that the antifouling property will last.In the case of coating, the antifouling layer (8) is formed on the entire surface by a conventional method, and in the case of printing, the antifouling layer (8) is formed by screen printing etc. The antifouling layer (9) is formed by printing on the entire surface, but if it is effective, it may be formed partially instead of on the entire surface.The silicone-based material used for the antifouling layer is silicone-based paint. Examples include paints containing organic alkoxysilane-based silicone substances such as methylhydrodiene polysiloxane and alkyltrialkoxysilane, and there are no particular limitations.
Examples of fluoro-based substances include fluoro-based paints, such as thermosetting paints that combine a fluoroepoxy compound and 7-mino silicone, paints that use fluoro resin powder as a binder with phenol resin, epoxy resin, etc. There are no particular restrictions on these materials.They are directly formed in close contact with or adhesively molded onto the surface of an insulating substrate, such as a plastic film, so that an antifouling layer is formed on the surface of the insulating substrate, resulting in a lasting effect. It is assumed that this can be expected. In addition, the antifouling layer (8) is formed in advance on the surface of the insulating substrate, transparent conductive substrate, etc. used for the surface of the touch panel before it is assembled into the touch panel, and then assembled into the specified touch panel. The antifouling layer (8
) is not particularly limited in the formation order.
