Abstract
An object of the present disclosure is to provide a film that has high water slidability, and a substrate having a surface covered with the film. The present disclosure provides a film having the properties of a sliding velocity of 150 mm/s or more at an inclination angle of 30° and an average surface roughness (Ra) of 1 μm or less, and further provides a substrate having a surface covered with the film.
Claims9
