FIELD: transport.
SUBSTANCE: invention relates to water repellant abrasion-resistant films to be used in vehicles. Proposed film comprises first layer with multiple fine ledges on its surface, second layer covering the latter and having water-repellant properties, and third layer made on first layer surface opposite said minor ledges. When first layer modulus of elasticity is E1, that second layer is E2 and that of third layer is E3, then satisfied is the following equation E2>E1>E3.
EFFECT: water repellant film with fine abrasion resistance.
