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, lead salt". The plastic surface is treated with a sulfide solution. Finally, the plastic surface is metallized in a metallizing bath.

L'invention porte sur un procédé de métallisation d'une surface en plastique et comprend les étapes suivantes: la surface en plastique est d'abord soumise à un traitement d'attaque chimique dans des conditions d'attaque chimique douces. Puis, la surface en plastique est traitée avec une solution de sel métallique contenant au moins un sel du groupe suivant: <=sel de cobalt, sel d'argent, sel d'étain, sel de plomb >=. La surface en plastique est traitée avec une solution sulfurée. Enfin, la surface en plastique est métallisée dans un bain de métallisation.
