Document Type and Number:
WIPO Patent Application WO/2023/188446
Kind Code:
A1
Abstract:
[Problem] To provide a silver-plated material that not only has excellent wear resistance but can also keep the peeling resistance of a silver coating layer high, even when exposed to high-temperature/high-humidity environments. [Solution] According to the present invention, a production method for a silver-plated material includes an electro silver plating step for forming a silver coating layer on a base material by means of an electroplating method that uses a cyanide-containing silver plating liquid in which a benzothiazole or a derivative of a benzothiazole has been dissolved and a heat treatment step for holding the silver coating layer at a temperature of 150°C–300°C for 3–30 seconds. Mercaptobenzothiazole or a derivative of mercaptobenzothiazole can, for example, be used as the benzothiazole or the derivative of a benzothiazole.
