摘要： Disclosed herein is a method for forming a multilayer coating film by sequentially coating an intermediate coating material composition, a base coating material composition and a clear coating material composition on a metal for a motor vehicle body or resin material and then thermally curing the compositions, where the clear coating material composition is obtained by mixing a main agent (A) and a curing agent (B).

摘要： A sliding member includes, on a surface of a metal substrate, a surface-treated layer including a zinc-electroplated layer, a chemical conversion-treated layer, and a topcoat layer sequentially stacked on the metal substrate. The chemical conversion-treated layer includes chromium and oxygen. The topcoat layer includes at least one material selected from the group consisting of a silica compound, acrylic resin, polyurethane resin, epoxy resin, phenol resin, and melamine resin. A method of manufacturing the sliding member includes a step of forming, on a surface of the chemical conversion-treated layer, the topcoat layer including at least one material selected from the group consisting of a silica compound, acrylic resin, polyurethane resin, epoxy resin, phenol resin, and melamine resin.
