PROBLEM TO BE SOLVED: To provide a substrate with a water-repellent film which film has durability such as moisture resistance, is excellent in both of static water repellency and dynamic water repellency, and particularly has a high level of dynamic water repellency and to provide an article for transportation equipment, which article comprises the substrate with the water-repellent film.SOLUTION: The substrate with the water-repellent film includes: the substrate; an underlying layer which is formed on at least a part of the surface of the substrate, is based on silicon oxide, and includes an oxide of an element M having the electronegativity lower than that of a silicon atom; and a water repellent layer which is formed above the underlying layer by using a water repellent layer formation composition containing straight-chain polyorganosiloxane having a hydrolyzable silyl group at the terminal and/or a partially-hydrolyzed condensate thereof. The article for transportation equipment, which article comprises the substrate with the water-repellent film. |
