Abstract
A process for the metallization of a plastic surface, whereby the following process steps are performed in sequence, one after another. The plastic surface is subjected to an etching treatment under mild etching conditions. Subsequently, the plastic surface is treated with a metal salt solution, containing at least one salt from the following group: cobalt salt, silver salt, tin salt, and lead salt. The plastic surface is treated with a sulfide solution. Finally, the plastic surface is metallized in a metallizing bath.
