| description | To provide a coating film that has a fluoropolyether structure and is excellent in wear resistance.SOLUTION: The coating film has a polysiloxane skeleton. In the coating film, a monovalent group (a) having a perfluoroalkyl group represented by CF- in an end thereof is bound to at least some of the silicon atoms of the polysiloxane skeleton, the group (a) has a perfluoropolyether structure in the group and has at least one of groups represented by -CF-, and the ratio of CFfragment ion strength to the maximum strength of CFfragment-ion strength measured by a time-of-flight secondary ion mass spectrometer is 0.25 or more.SELECTED DRAWING: None
【課題】フルオロポリエーテル構造を有し、耐摩耗性に優れる皮膜を提供する。【解決手段】ポリシロキサン骨格を有する皮膜であって、該皮膜では、ＣｎＦ2n+1−で表されるパーフルオロアルキル基を末端に有する１価の基（ａ）が、前記ポリシロキサン骨格のケイ素原子の少なくとも一部に結合しており、前記基（ａ）は基中にパーフルオロポリエーテル構造を有すると共に、−ＣmＦ2m−で表される基の少なくとも１種を有し、飛行時間型二次イオン質量分析計によって測定したＣmＦ2mフラグメントイオン強度のうちの最大の強度に対する、ＣｎＦ2n+1フラグメントイオン強度の比が０．２５以上である皮膜。【選択図】なし |
