Abstract
The invention relates to a polymer-based artificial turf fiber comprising substances () adapted for protecting the fiber against UV radiation. The substances comprise a hindered amine light stabilizer—HALS and a first and a second UV-absorbent substance. The molecular weights of the first and the second UV-absorbent substances differ from each other by at least 100 g/mol.
