<P>PROBLEM TO BE SOLVED: To provide a method for preventing corrosion of a metallic layer, which makes the sulfur resistance of the metallic layer superior and controls the corrosion of the metallic layer, such as tarnish. <P>SOLUTION: The method for preventing corrosion of a metallic layer, covers the metallic layer obtained from a metal of group 11 with a silicon resin layer obtained from a silicon resin composition containing (A) 100 mass parts of organosiloxane including at least one or more reactive functional groups in one molecule; and (B) a metallic compound containing at least one kind selected from the group containing Ni, Cu and Ga, thereby controlling the corrosion of the metallic layer. <P>COPYRIGHT: (C)2012,JPO&INPIT |
