Abstract
The invention provides a method for the preparation of a shaped article of a flexible or semi-rigid polyvinyl chloride resin having a metallized surface, of which the adhesive bonding of the metallizing layer to the substrate surface is greatly improved. In the inventive method, the surface of the shaped article is first exposed to low temperature plasma generated in an atmosphere containing a vapor of a specified organosilicon compound before the metallizing treatment in a dry process such as vacuum vapor deposition, ion plating and the like.
