Description

ABSTRACT:
The present invention relates to a method for treating plastic substrates structured by means of a laser or generation of seed structures on the surface that are suitable for subsequent metallization. The substrates, after the laser structuring, are brought into contact with a process solution that is suitable for removal of the unintentional deposits that arise during the laser structuring. The treatment of the laser-structured substrates with a mixture of wetting agents and compositions that support the cleaning before metallization leads to sufficient removal of the unintentionally deposited metal seeds, without having a lasting damaging effect on the planned structured surface paths.
