Abstract: Provided is a leather material comprising a top coat having at least one layer on a leather substrate, wherein at least one of the layer contains a polycarbonate polyurethane resin, a polyester polyurethane resin, and a polyether polyurethane resin.

Abstract: A water repellent film (200) according to the present invention includes a first layer (10) having a plurality of fine protrusions (100) on the surface thereof, a second layer (20) covering the fine protrusions (100) and having a water repellent property, and a third layer (30) provided on the surface of the first layer (10) on the opposite side of the fine protrusions (100). When a modulus of elasticity of the first layer (10) is defined as E1, a modulus of elasticity of the second layer (20) is defined as E2, and a modulus of elasticity of the third layer (30) is defined as E3, a definition of E2>E1>E3 is fulfilled. Accordingly, the water repellent film having excellent resistance to abrasion in which a fine structure is not easily abraded and damaged by an external friction force or the like can be obtained.

Abstract: A water repellent anti-reflective structure with a superior water repellent function and an anti-reflective function, a method of manufacturing the same, and components of vehicles comprising the water repellent anti-reflective structure (e.g., display or window panel) are taught. Numerous cone-shaped projections having a circular or polygonal bottom surface and a diameter of a circular bottom surface or a circle circumscribing with a polygonal bottom surface within a range between 50 and 380 nm are configured to be arranged at a pitch within a range between 50 and 380 nm, having an aspect ratio within a range greater than or equal to 1.5 and made from material having a contact angle with water equal to or greater than 90°.
