Abstract

A method for producing an anti-fouling coating film includes: a step (1) of applying a fine uneven layer forming agent containing at least one type of polysilazane as at least one type of silica raw material on at least one surface of a base substrate, the aforementioned at least one surface comprising at least one type of resin, to form a fine uneven layer containing silica and polysilazane; a step (2) of applying a modification layer forming agent containing a reactive organic compound and polysiloxane or perfluoropolyether on a surface of the fine uneven layer obtained in the step (1), to form a modification layer containing polysiloxane or perfluoropolyether, and a step (3) of applying lubricating oil containing silicone oil or fluorinated oil on a surface of the modification layer obtained in the step (2), to form a lubricating oil layer.

First claim

1 - 7 . (canceled)

8 . A method for producing an anti-fouling coating film, comprising:
a step (1) of applying a fine uneven layer forming agent containing at least one type of a polysilazane as at least one type of a silica raw material on at least one surface of a base substrate, the aforementioned at least one surface comprising at least one type of a resin, to form a fine uneven layer containing a silica and a polysilazane; a step (2) of applying a modification layer forming agent containing a reactive organic compound and a polysiloxane or a perfluoropolyether on a surface of the fine uneven layer obtained in the step (1), to form a modification layer containing the polysiloxane or the perfluoropolyether; and a step (3) of applying a lubricating oil containing a silicone oil or a fluorinated oil on a surface of the modification layer obtained in the step (2), to form a lubricating oil layer.

9 . The method for producing an anti-fouling coating film according to claim 8 , wherein, in the step (1), a silica conversion promoting treatment is performed after applying the fine uneven layer forming agent, to form the fine uneven layer.

10 . The method for producing an anti-fouling coating film according to claim 9 , wherein, in the step (2), a modification promoting treatment is performed after applying the modification layer forming agent, to form the modification layer.

11 . The method for producing an anti-fouling coating film according to claim 9 , wherein the silica conversion promoting treatment is to retain the fine uneven layer forming agent applied under an environment, in which at least one of a humidification and a warming is performed.

12 . The method for producing an anti-fouling coating film according to claim 10 , wherein the modification promoting treatment is to retain the modification layer forming agent applied under an environment, in which at least one of a humidification and a warming is performed.

13 . The method for producing an anti-fouling coating film according to claim 8 , wherein, in the step (2), a modification promoting treatment is performed after applying the modification layer forming agent, to form the modification layer.

14 . The method for producing an anti-fouling coating film according to claim 13 , wherein the modification promoting treatment is to retain the modification layer forming agent applied under an environment, in which at least one of a humidification and a warming is performed.

15 . An anti-fouling coating film disposed on a base substrate having at least one surface comprising at least one type of resin,
wherein the anti-fouling coating film comprises: a fine uneven layer disposed on the base substrate having the aforementioned at least one surface, the fine uneven layer containing a silica and a polysilazane; a modification layer disposed on a surface of the fine uneven layer, the modification layer containing a polysiloxane or a perfluoropolyether; and a lubricating oil layer disposed on a surface of the modification layer, the lubricating oil layer containing a silicone oil or a fluorinated oil.

16 . The anti-fouling coating film according to claim 15 , wherein the fine uneven layer differs in a polysilazane content in a thickness direction of the fine uneven layer, and the polysilazane content on a side of the base substrate is higher than the polysilazane content on a side of the modification layer.
