<p>The present invention relates to an article having a silver layer and a resin composition for a coating material for silver which is used in reflective mirrors of photocopy machines and reflective members for indoor and outdoor lighting appliances, automobile headlights and the like. The article having a silver layer of the present invention has a first cured coating layer (A) comprising a resin having anti-corrosion properties for silver, and adhesiveness for both the substrate and silver or a metal comprising mainly silver formed between the substrate and the silver layer (B); and, formed on the silver layer (B), a second cured coating layer (C) comprising a resin selected from the group consisting of a silicone acrylic resin (c1), a silicone alkyd resin (c2), and a multi-functional silicone cross-linked resin (c3) having a main chain formed by siloxane bonds. This type of article having a silver layer is superior in anti-discoloration (anti-corrosion) properties of the silver layer (B). In addition, since the resin composition for coating materials for silver of the present invention contains a multi-functional silicone cross-linked resin (c3) having a main chain formed by siloxane bonds, it is superior in heat resistance, there is no yellowing of the coating thereof even when exposed to temperatures around 200° C., and it gives superior anti-discoloration (anti-corrosion) properties to silver.</p> |
