Abstract
This invention relates to a process for the preparation of UV protective coatings by plasma-enhanced vacuum deposition, using hydroxyphenyl-s-triazines as UV absorbers. This invention also relates to the use of hydroxyphenyl-s-triazines in plasma-enhanced vacuum depositions and to the substrates coated by this process.
