Abstract
A process for metal-coating plastic surfaces by chemical pretreatment with n acid pickling agent whereby to prepare the plastic surfaces for the subsequent superposition thereon of a metal layer is described. The plastic surfaces to be coated are chemically pretreated by means of an acid pickling agent in the gaseous phase, the chemical pretreatment is then terminated by chemical reaction of the said pickling agent with another material in the gaseous phase to form gaseous reaction products. If desired, the chemically pretreated plastic surface may then be treated with an aldehyde in solution. The treated surface may then be metal coated, if desired employing a galvanic process without external current.
