Method for the electroless deposition of a metal layer on a flat article from a metallisation liquid, a device for carrying out said method and a master disc obtained according to the method.

摘要

The method serves for the electroless deposition of a metal layer (7) from a metallisation liquid on a top side of a flat article to be metallised, more in particular a flat disc, for example, a master disc (1) which is used for the reproduction of optical discs. According to the method the top side of the article is first made hydrophilic, if so necessary, after which, with the article supported in a horizontal position, a quantity of metallisation liquid is provided on the top side which was previously made hydrophilic as a stable liquid layer (16) bounded by the edges of the article, after which the deposition of the metal from the liquid on the article takes place and the liquid layer is the removed entirely from the surface. <IMAGE>
