Abstract: A surface decoration structure includes an undercoat film, a silver mirror film layer, and a topcoat film formed on a surface of a substrate. The silver mirror film layer includes a film of stacked nanometer-sized silver particles having surfaces coated with a polymer dispersing agent, and the topcoat film includes, as a solvent, at least one member selected from the group consisting of an aliphatic hydrocarbon compound, an aliphatic hydrocarbon compound solution including 10% by mass or less of an aromatic compound, and diisobutyl ketone. The undercoat film and/or the topcoat film may include a corrosion inhibitor. The silver mirror film layer may further include a corrosion inhibitor. The surface decoration structure includes the silver mirror film layer with improved luster and corrosion resistance.

Abstract: A bicycle disc brake rotor is basically provided with a main body and a heat release layer. The main body is made of a metallic material. The main body includes an outer portion, an inner portion and a cooling facilitation part. The outer portion has oppositely facing braking surfaces. The heat release layer includes a non-metallic material. The heat release layer at least partially overlies the cooling facilitation part.
