Abstract: A heat-insulating layer exhibiting high resistance to cracks, peeling, deformation, and gasoline and high heat insulation is obtained on the wall surface of an engine member (19). First, a heat insulator layer including a silicone-based resin and hollow particles containing a Si-based oxide is formed on a wall surface of the engine member (19). Then, Si-based oxide is produced through oxidation of a silicone-based resin in at least part of the surface of the heat insulator layer by heating the surface of the heat insulator layer. Thereafter, a catalytic metal is added to the silicone-based resin in the surface of the heat insulator layer and/or Si-based oxide derived from the hollow particles. Using the catalytic metal as nuclei, electroless plating is performed. In this manner, a heat-insulating layer (21) in which the surface of the heat-insulating film (27) is covered with a plating film (29) is obtained.

Abstract: A transparent layered structure having a high abrasion resistance and a high scratch resistance and a method for producing such a transparent layered structure are provided. A transparent layered structure (1) includes: a plate-like transparent resin base (2); and a transparent protective film (3) located on one surface of the base (2). The heat resistance, for example, of the base (2) is set in a predetermined range so that a light-weight transparent layered structure (1) having a predetermined load resistance is achieved. The protective film (3) includes a silicone resin composition including 9 wt % or more of cage silsesquioxane and fine particles (4) constituted by glass fine particles or metal oxide fine particles subjected to a surface treatment with a silane compound under predetermined conditions. Thus, the transparent layered structure (1) obtains a high abrasion resistance and a high scratch resistance.

Abstract: In a process which is before a treatment process of forming a chemical conversion, TiO2 fine particles as an electron releasing-related substance (electron releasing substance) are attached onto a surface of a vehicle body. Then, a chemical conversion treatment is applied to the vehicle body having the TiO2 fine particles attached thereto. Thereby, an energy band gap of a finally-formed chemical conversion film can be smaller than that of a chemical conversion film formed by using only a chemical conversion treatment agent. Accordingly, the number of electrons (free electrons) which can be supplied onto the surface of a chemical conversion film can be increased during a voltage application in an electrodeposition coating process, and reducing reaction at a cathode can be promoted.
